Fertilization of young citrus trees

How do young citrus trees fertilize
Apply heavy fertilizer deeply, lead root deep growth.Young citrus trees are usually fertilized twice a year with heavy fertilizer, deep furrow fertilizer, and mainly organic fertilizer.Generally, in the summer rain more, high humidity, when the weeds are abundant, in the winter when the branches are old and ripe, after the plant stopped growing again.Fertilization, from citrus tree 50 to 60 cm, youth by the east-west and south-north dig a 50 to 60 cm deep, 30 to 40 cm wide, 80-100 cm long, deep groove, position of successive change, each ditch various weeds 25 to 30 kg, retting of rotten people of livestock and poultry dung 8-10 kg or 1.5 2 kg of biological organic fertilizer.The weeds are applied to the bottom of the deep ditch, and the fertilizer is mixed with the soil excavated when the deep ditch is dug. After that, the weeds can be filled back into the deep ditch and buried under pressure.
Fertilization of young citrus trees
Apply thin fertilizer frequently, a small amount many times.On the basis of deep heavy fertilizer, citrus young trees every smoke twice fertilizer, gave birth to a new tip is given priority to with quick-acting instant NPK fertilizer completely, respectively, in the old body-to keep full, ripe new tip for germination of new tip and completely show leaf, leaf size basic finalize the design, when leaf light green color.Every time shi NPK (20-20-20) of a water soluble fertilizer 80-100 grams, add water or biogas slurry or retting of rotten people and livestock manure after 5-6 kg, evenly spray on surface soil under canopy, with fat liquid infiltration into the soil completely not outflow is advisable.Or every time each NPK (15-15-15) potassium nitrate harvard or pure 150-200 grams of s-based compound fertilizer, around the canopy drip line, dig deep, each 25 to 30 cm wide ring of shallow groove, the fertilizer evenly broadcast inside the ring fence, cover soil, covering the fertilizers.With the continuous growth of citrus young trees, the amount of fertilizer gradually increased to meet the needs of growth and development.
Citrus fertilization
Apply fertilizer on the leaf surface to supplement nutrients.On the basis of applying fertilizer to citrus root, it is necessary to apply fertilizer to the leaves many times to supplement the nutrients needed by citrus.Every 10 to 15 days commonly foliar spraying 1 0.1% 0.1% magnesium sulfate, zinc sulfate, 0.2% urea and 0.3% potassium dihydrogen phosphate, 600 times amino acid compound micronutrient fertilizer mixture, evenly spray wet all the branches and leaves, to begin it is advisable to have water drops down.
Citrus trees youth fertilizer fertilization technology is to introduce you to them and grow according to the friend, you can refer to these fertilization method, according to the actual situation of planting, fertilizer reasonably.

Plant growth regulator 5 big use error, careful "labor not please"!

In recent years, plant growth regulator in enhance crops resistance and increase crop yield, improve product quality, improve the efficiency of the plant played a huge role, has been recognized by more and more farmers.However, there are some obvious errors in the use of many farmers, which seriously affect the use effect.Here should remind the farmer friend when using plant growth regulator, want to prevent to enter the following five mistakes.


Myth no. 1: replace "fat" with "agent"
Plant growth regulator must be under the condition of sufficient water to exert significant effect, but the effect of some plant growth regulator was exaggerated by the manufacturers use, led some farmers use it as fertilizer use, to promote crop growth of hope on plant growth regulator, and not in the conventional technologies such as fertilization, irrigation and intertillage, digging up and down time, ultimately affect the use effect of plant growth regulator.
Myth 2: increase the dosage at will
Plant growth regulator is a hormone substance, generally only a few grams or a few milliliters per mu.But some less dosage of farmers always afraid of no effect, increase dosage of plant growth regulator or use concentration at random, not only can not promote plant growth, it will make its growth is restrained, serious and even lead to leaf malformation, dry off, whole plant death.
Myth 3: use water directly
Some plant growth regulators, such as more gibberellin used in production, must be dissolved with alcohol or warm, high - temperature liquor before water use.However, some farmers often do not read the instructions carefully before using plant growth regulator, but use plant growth regulator directly to water.Due to some plant growth regulator can not directly be dissolved in water, combined with the trace of plant growth regulator without prior mixture mixture again after "mother liquor" requires concentration, reagent is hard to a blender, will also affect the use effect.
Myth 4: mix with other substances at will
Whether plant growth regulators can be mixed with fertilizers, pesticides and other substances must be carefully read and tested before it can be determined.But many farmers in the use of plant growth regulator, to graph save trouble, often will be randomly mixed with chemical fertilizers, pesticides, fungicides, etc, to promote growth or flower and fruit, at the same time adding fertilizer or preventing pest.However, if the mixture is not appropriate, it will "double the effort" or even "lose the effort".
Myth 5: never look at the right time, always spray
Plant growth regulator must be used at the critical time of plant growth (such as the differentiation period of cucumber flower buds) to achieve the maximum effect.If used at the wrong time, the desired effect will not be achieved, and there may even be "side effects".Some farmers have insufficient understanding, think whenever spraying plant growth regulator, to be able to promote growth, increase production, income effect, so don't look at time, spraying at any time, lead to the spraying effect is not good, some even production, reduce.

Principles and application of water treatment agents

Water treatment agent is a necessary chemical agent in the process of industrial water, domestic water and waste water treatment.It is the first effect of moderate scale and the composition of the sludge, reduce foam, cutting materials contact with the water erosion, remove the suspended solid in the water, and toxic substances, deodorant decoloring, softened water, etc.
Sharply because the current world nations water to add, also all kinds of environmental statutes heels (water purification method) to formulate, severe day by day and so on all kinds of efficient water disposal reagents to improve soon.In our country, and the capital of the increasingly serious water crisis contradiction of water disposal reagents is produced to a very low, quality also is not all, so accelerate the development of the environmental protection material property of water disposal reagents to carry out the fire.

Ukraine: UN experts warn of chemical disaster and water safety risk as conflict escalates in East

GENEVA (10 November 2017) – Ukraine is facing new risks of chemical disaster and water safety after an escalation of conflict near water supply facilities in the east of the country, two UN Special Rapporteurs have warned.
“We are alarmed by recent reports of shelling around water installations containing chlorine gas and other extremely dangerous chemicals in Donetsk region,” said Baskut Tuncak, an expert on human rights and hazardous substances, and Léo Heller, whose mandate covers safe drinking water and sanitation.
“Damaging installations containing substances such as chlorine gas and the destruction of water treatment facilities could have devastating consequences for the population and the environment of large areas in Eastern Ukraine,” they added.
Chlorine gas, which can cause severe health impacts and death by asphyxiation, has been used as a chemical weapon, but is not specifically listed as controlled under the Convention on Chemical Weapons. However, the use of any toxic chemical as a weapon, including chlorine, is forbidden under the Chemical Weapons Convention.
The Donetsk water filtration station was reportedly shelled repeatedly between 3 and 4 November, causing damage to a back-up chlorine pipeline.
It is reported that if the main pipeline currently in use or any single 900kg bottle containing chlorine, stored in these facilities was hit, it could have killed anyone within a 200 metre radius, including the staff of the facility, and would have disrupted the water supply to almost 350,000 people on both sides of the contact line.
On 5 November, a second water filtration station, Verkhnokalmiuska, which supplies clean water to 800,000 people and stores 100 tons of chlorine gas, was hit by multiple shells. “Again, releasing toxic gas and destroying water supply facilities would have had devastating consequences for populated areas of Donetsk city, Makiivka and Avdiivka,” the experts said.
Mr. Tuncak, who has previously warned of the risks of chemical disasters in eastern Ukraine, added: “All parties involved in conflict must respect international humanitarian law, notably by taking into account the potential consequences of unleashing highly toxic chemicals on the civilian population.”
Mr. Heller noted: “Interference with water and sanitation supplies even in the context of conflict is entirely unacceptable. The rights of almost 1.1 million people’s access to safe drinking water and sanitation on both sides of the contact line are at risk of being affected if hostilities continue to hit water treatment facilities.”
Both experts called on the parties to hostilities to create and respect demilitarized zones around critical water sites in Donetsk region, as was agreed by the Trilateral Group on 19 July this year.
The experts also called for attention to structures at risk of collapse due to poor maintenance. A sludge collector at the phenol plant in Novhorodske has not been repaired after shell damage. Maintenance due every two weeks has not been carried out for a year. Reportedly, the dam around the collector is eroding, risking the release of liquid toxic waste into the Kryvyi Torets and Siverskyi Donets rivers.

“Ensuring access to, and adequate maintenance of, damaged sites containing hazardous substances is vital. We call on all parties to agree on and respect adequate security arrangements which would allow regular maintenance as well as repairs to be conducted safely,” concluded the human rights experts.

Fertilizer industry representatives attend the UN Committee on World Food Security

Rome: 15 October 2015 – A fertilizer industry delegation led by Chairman Abdulrahman Jawahery and Director General Charlotte Hebebrand attended the 42nd session of the Committee on World Food Security (CFS) in Rome this week.
The mission included a meeting with FAO Director General Graziano da Silva. During this meeting, Dr. Jawahery reiterated the industry’s commitment to increasing access to inputs and technology by smallholders “We believe that it is of utmost importance to continue developing a broad range of practical programs to improve smallholder access to inputs. This includes financing, of course, but it also comprises services to farmers in form of technologies and knowledge transfer.”
Mr. da Silva commended the private sector for playing a crucial role in achieving zero hunger and combatting malnutrition. The private sector’s commitment was also highlighted by the unprecedented attendance of over 140 delegates.
The IFA delegation had several bilaterals with country actors and participated in two side-events/ Charlotte Hebebrand spoke in a side-event on nutrition organized by the World Food Programme and the Scaling Up Nutrition (SUN) movement. Hebebrand presented several case-studies on micronutrient fertilization concluding that “Micronutrient fertilization is a simple, affordable and sustainable solution to contribute to eradicating deficiencies globally. This makes it a viable program which can be tailored to regional and national needs and implemented worldwide.”
In another event organized by the International Year of Soils Steering Committee, Hebebrand spoke to the merits of integrated soil fertility management and highlighted that “Soil testing is important so farmers can learn exactly how much of each nutrient is required to ensure balanced fertilization using locally available organic nutrients and mineral fertilizers. “
The voice of the fertilizer industry was also heard in Plenary where Dr. Jawahery delivered a compelling statement on Action on Food Insecurity in Protracted Crises. He stressed that “The private sector, is the biggest engine of poverty reduction and economic growth in the developing world and thus stands ready to contribute to securing food availability for people living in protracted crises”.

The IFA Chairman also hosted the High-Level Dinner which brought together business leaders and ambassadors, which provided a vibrant forum for discussion among private and public actors. IFA and its members have been actively engaging in the CFS through the Private Sector Mechanism. Moreover, IFA has developed a longstanding relationship with the Rome-Based Agencies and currently sits on the Steering Committee of the International Year of Soils.

Pesticides linked to birth abnormalities in major new study

High exposure to pesticides as a result of living near farmers’ fields appears to increase the risk of giving birth to a baby with “abnormalities” by about 9 per cent, according to new research.
Researchers from the University of California, Santa Barbara, compared 500,000 birth records for people born in the San Joaquin Valley between 1997 and 2011 and levels of pesticides used in the area.

The average use of pesticides over that period was about 975kg for each 2.6sq km area per year.

But, for pregnant women in areas where 4,000kg of pesticides was used, the chance of giving birth prematurely rose by about 8 per cent and the chance of having a birth abnormality by about 9 per cent.

Writing in the journal Nature Communications, the researchers compared this to the 5 to 10 per cent increase adverse birth outcomes that can result from air pollution or extreme heat events.

“Concerns about the effects of harmful environmental exposure on birth outcomes have existed for decades,” they wrote.

“Great advances have been made in understanding the effects of smoking and air pollution, among others, yet research on the effects of pesticides has remained inconclusive.

“While environmental contaminants generally share the ethical and legal problems of evaluating the health consequences of exposure in a controlled setting and the difficulties associated with rare outcomes, pesticides present an additional challenge.
“Unlike smoking, which is observable, or even air pollution, for which there exists a robust network of monitors, publicly available pesticide use data are lacking for most of the world.”

They said exposure to pesticides varied greatly in the San Joaquin Valley, with more than half of the births in places where there were no pesticides used in the area.
“For most births, there is no statistically identifiable impact of pesticide exposure on birth outcome. Yet, for individuals in the top 5 per cent of exposure, pesticide exposure led to 5 to 9 per cent increases in adverse outcomes,” they said.
“The magnitude of effects was further enlarged for the top 1 per cent, where these extreme exposures (more than 11,000kg over gestation) led to an 11 per cent increased probability of preterm birth, 20 per cent increased probability of low birth weight, and about a 30g decrease in birth weight.

“For birth abnormalities, being in the high versus low pesticide exposure group for cumulative pesticide use over gestation increased the probability of a birth abnormality by about 9 per cent (5.8 per cent of births have a birth abnormality in this sample).”

Levels of pesticide use depended to a large degree on the types of crops being grown.

“Commodities such as grapes receive nearly 50kg per hectare per year of insecticides alone in the San Joaquin Valley region, while other high value crops such as pistachios receive barely one third of that amount,” the researchers said.
They were unable to isolate the roles of different chemicals used in the study.
“Doing so is extremely challenging, because many chemicals are used in conjunction or in close spatial or temporal windows,” the paper said.
Commenting on the study, Professor Alastair Hay, an environmental toxicologist at Leeds University, said it had been “very well conducted”.
“This study will be picked over carefully by regulatory agencies, as indeed it should be,” he said.

“The sheer size of the study, and the meticulous way it has been carried out, suggest that there is an environmental hazard for mothers resident in an area with large-scale pesticide usage and that investigation of measures to mitigate exposures to the chemicals are needed.”

He said it was not clear which pesticides had been used, but added that the study was “likely to have wide applicability in view of the type of crops sprayed”.
“And given that the risk is clearly in the area most heavily exposed – which you would expect to see if the problem were real – there are clear messages that mitigation measures are needed,” Professor Hay said.

Dr Christopher Connolly, a neurobiologist at Dundee University, said the study reported “a significant increase in adverse birth effects that relate to high level pesticide use”.

“However, the devil is in the detail, and the detail is missing – which pesticide(s) are responsible for these effects?” he said.

“This makes it important that the study is repeated with a detailed list of the chemicals used at each site and the impact on births correlated to individual pesticide (and cocktail) application.


“In the UK, the average total pesticide load in intensively managed arable fields is about 1.5 times higher than the average reported in this study area, but is 10-fold lower than the high pesticide load reported to correlate with adverse birth effects in this study.

Just add water: how to take cuttings from houseplants

I am the crazy cat lady of the house plant world. I have so many of them. Closing the curtains has become quite the task, as you snake between specimens all vying for light. And yet I continue to take cuttings.
Many house plants are easily rooted in water. I love to watch roots grow, particularly in winter, when there’s something so cheering about a life so willing. Truth be known, it makes most sense to take cuttings in spring and summer. On top of that, cuttings taken in water are somewhat inferior to those taken in soil, in part because water doesn’t offer the most nutritious beginning. But that doesn’t stop me.
Philodendrons, begonias, tradescantia, pilea, peperomias, ctenanthe (but sadly not calathea) and rhipsalis are just a few of the types that will readily root in water.
In general, cuttings should be 10-15cm long – larger cuttings may take, but the ratio of stem to root often makes for a weak plant. Use a sharp knife or secateurs and cut just below where a leaf attaches to the stem, known as a node. If you leave a section of stem below the node, this will likely rot off.
As well as the lowest leaf, you may need to remove a few more, leaving just the top two or three. Essentially, any part of the cutting that sits in water should be free of leaves that will rot. Fetid water is not a nice place to start a life.
Also remove any flowers that are present, to prevent the cutting from developing seed, which will waste energy that would be better diverted to creating roots. And, again, the flowers may go mouldy and rot.
Little vases, water or milk bottles are ideal for rooting. If there is a wide neck, you may have to create some sort of mesh across the top so that the cutting doesn’t fall into the water. You can also have several cuttings together in one container.
Choose a smaller container than you’d imagine. The cutting will release hormones into the water to encourage rooting, and a great volume of water will dilute them, so that the process takes longer.
Rooting will generally occur in three to four weeks, though some begonias and pilea take much longer. Keep the cuttings somewhere bright and warm, and be patient. If a particular stem in a group of cuttings goes mushy and starts to rot, whip it out before it contaminates the rest. When there are numerous roots, 2-5cm long, the cutting is ready to be potted up.

Pot into pre-moistened potting compost in a suitably sized container with drainage, and keep the compost moist but not sodden until you see new growth. If the cutting grew in the water – and many do – it may be a good idea to prune it back a little when potting up. This will force new growth at the base and make for a bushier plant.

2 Kinds Of High-Quality Insecticide Details For Banana

Most people like to eat Bananas, but pests are abhorrent to banana farmers. However, now a wide range of pesticides, bananas should choose what kind of insecticide it dose? Here are two kinds of banana premium insecticides.



1. Cicadae belongs to the Bacillus thuringiensis variants, this type of insecticidal bacteria on humans, animals, crops, aquatic crops non-toxic, better stability, and other pesticides can be mixed.

The bacteria on more than 150 kinds of insects, especially Lepidoptera insects have varying degrees of pathogenic and toxic killing effect, when pests eat such insecticidal bacteria, will soon stop feeding, nerve paralysis, insect body softening, Rotten stink death. Preparation of a WP (10 million live spores / g) and emulsion (10 billion live spores / ml) two, spray, dusting, poison soil and other means of administration, the commonly used dose of 50 grams per acre of powdered bacteria. If mixed pyrethroids or trichlorfon and other pesticides, there is a clear synergy. But can not be mixed with fungicides or systemic organophosphate pesticides. Apply the temperature above 30 ℃ the best, should be used with caution in the sericulture area.

2. Rattan fine root extract from the roots of Fu plant botanical insecticides, with contact and stomach poisoning effect on aphids and lepidopteran larvae better. For humans and animals, the crop is extremely safe, especially suitable for fruits, vegetables, tea, mulberry use, commonly used 2.5% fish rubber latex EC 500-800 times spray.

The above is a small series for everyone to introduce two kinds of high quality banana insecticide, I hope we can help prevent banana pests.

Prospect of Water Treatment Technology in China

With the environmental problems more and more serious, environmental protection is gradually into the country's vision. At the same time, a lot of water treatment technology is also made great progress, in general, that is efficient, simple and convenient, low energy consumption.


1, adhere to the road of sustainable development

Water treatment products

Although the protection of the environment is very important, can not put aside the economy, hinder its development. In order to coordinate the relationship between the two, the government departments can actively encourage enterprises to adopt fund-raising approach, while ensuring economic development, vigorously build sewage treatment plants, increase the intensity of sewage purification.
2, the construction of environmentally friendly, efficient sewage treatment plant
Perhaps many people do not know, in fact, sewage treatment plants will produce waste gas, sludge. If we ignore it, it will cause secondary pollution. So, we can take a certain approach to remove the exhaust gas. For example, we can clean up the waste gas produced by the treatment of sewage through the deodorant burner. Perhaps three or five years, or ten years later, and so on when environmental technology has matured, the treatment of waste sludge more scientific and reasonable, so that the sewage treatment plant to become the number one role in the elimination of pollution it!

Water treatment products

In the construction of sewage treatment plants, we can not but consider the cost, can not but consider the speed of resource consumption. Therefore, we should also vigorously develop water treatment technology, hoping to develop a low energy consumption, high efficiency processing technology. This will not only reduce costs, but also improve water quality, thereby improving the environment we live.
3, to change the operating mechanism of sewage treatment plants
Although the construction of sewage treatment plants inseparable from the improvement of water resources and environment, but if the factory is always operating regardless of the cost, it is estimated that no one is willing. So, if we turn the sewage management plant into a business model, so that they also have some economic benefits, is it can make the sewage treatment plant treatment effect can be improved? Because once transformed into a business model, sewage treatment plants will certainly find ways to improve their own sewage treatment methods to improve water quality. In this way, they will be actively involved in the improvement of water treatment research, and actively promote the improvement of water treatment technology.

Water treatment products

4, to improve the reuse rate of recycled water
Sewage treatment is not necessarily to meet the requirements of drinking can be considered standard, because some of the water production standards are not so high. Therefore, when the sewage after a certain treatment, if you can achieve some of the requirements can be used after the use, no longer need to clean. This will not only realize the reuse of sewage, but also can save processing costs and improve water treatment efficiency. With the scientific and technological constantly updated, sewage treatment technology must also be more mature, the scope of application will be more broad, may be able to apply to agriculture, industry, life and other aspects.
5, properly handle the sludge
After the sewage treatment, often produce a certain amount of sludge. Some of these sludge may contain heavy metals and other poison, but it is not nothing. As long as we are based on the composition of the sludge, and then to be analyzed, naturally you can find a proper way to deal with them so that they can also be used to achieve the purpose of effective use and conservation of resources.

Activated Sludge Treatment of Refining Sludge Wastewater

The activated sludge method was used to treat the alkali residue wastewater after pretreatment in a refinery. The activated sludge was domestically acclimated with the target wastewater as the carbon source, and then the domesticated alkali sludge was treated with domesticated activated sludge to reduce its COD (chemical oxygen demand) value. The experimental results show that the biochemical treatment of activated sludge has a significant reduction effect on the COD value of the alkali residue wastewater. Under the conditions of hydraulic retention time of 24 h, the average removal rate of COD is up to 76% and the volume load is about 0.7 kg COD / (m3 • d). After 10 days of operation, the total COD removal rate can reach about 74% Water quality reached the national emission standards (GB 8978-1996).

Refining caustic soda wastewater is the waste caustic soda generated during the alkaline scrubbing of petroleum products during the oil refining process. The main components are Na2S, mercaptans, thioethers, thiophenes, phenols, quinones and naphthenic acids, which are difficult to handle in high concentration organic One of the waste water. At present, researchers use a variety of treatment technologies based on the characteristics of industrial wastewater, including high-temperature wet oxidation and mild wet air oxidation. The United States Zimpro company first developed a wet air oxidation of industrial applications, and its application in the treatment of harmful petrochemical waste and waste. The process of organic and sulfide treatment efficiency, but the reactor requirements (high temperature, high pressure).

This kind of wet oxidation technology has a good effect on wastewater treatment, but requires large equipment investment and high energy consumption, which can not completely mineralize nitrogenous compounds and PCBs, thus limiting its wide application. Wright Chemical Company for many years and South Korea SK Group Institute of Biological Experimentation, SK will be highly efficient biological treatment technology used in the treatment of high-concentration caustic wastewater, the creation of the Wright bio-technology. This process has high adaptability to changes of pollutant concentration, poison concentration and salinity in wastewater.

However, the phenomenon of temperature increase during the operation of the process is obvious, which will seriously reduce the oxygen-dissolving capacity of the muddy water mixture in the reactor and reduce the microbial activity. Han Jianhua on the wet oxidation of sulfur-containing refinery caustic sludge made in-depth study, put forward a 'mitigation of wet oxidation deodorization - acid recovery of phenol or naphthenic acid - SBR process (treatment of alkali residue waste water process, and in 1998, in Shanghai A petrochemical enterprise has designed an industrial pilot plant which can effectively oxidize the organic sulfides and inorganic sulfides in spent lye to eliminate sulfuric acid and eliminate the stench gas emissions from the further treatment of the spent lye.However, Moderate wet oxidation has the disadvantages of incomplete treatment and harsh equipment requirements, but also because of excessively high temperature, carbon residue easily causes the pressure in the reactor and seriously affects the normal operation of the treatment device. Biological treatment of organic wastewater is convenient and fast, Mild, low energy consumption, less investment, no catalyst addition and operational safety, etc., get the general attention of researchers.

Alkali residue COD in the water generally tens of thousands to hundreds of thousands

Because of its complex composition, contains many refractory organic matter, therefore, it is necessary to explore a new method of deep treatment of alkali-based wastewater treatment plant. In this experiment, the activated sludge was domestically acclimated with the wastewater to be treated as the carbon source, and its effect on the treatment effect of alkali-based wastewater from refineries was investigated.

Fulvic acid's four major roles!

Improve the soil

Improve soil aggregate structure. Fulvic acid is a humic substances, can affect the nature of the soil, promote soil to form a more stable aggregate structure, so that the soil content of ≥ 0.25mm increased by 10-20%, organic matter content increased by 10%, the soil can maintain water , Increase ventilation, is conducive to the growth of crops.

Enhance soil water retention. Fulvic acid is a kind of hydrophilic colloid with strong water absorption capacity, the maximum water absorption can exceed 500%, the weight of water absorbed from the saturated atmosphere can reach more than double its weight, which is much larger than the average mineral colloid; Fulvic acid inhibits crop transpiration, slowing the rate of soil water consumption and correspondingly increasing soil moisture content.

Enhance soil fertility. Fulvic acid itself is an organic acid, which not only increases the dissolution of the mineral part of the soil, provides soil nutrients, but also increases the effectiveness of nutrients through complexation. Fulvic acid as an organic colloid, with positive and negative charges, can absorb anion and cation, making these nutrients can be stored in the soil, not with the water loss, improve fertilizer utilization, the significance of the soil is particularly significant.


Promote the absorption of trace fertilizer, to solve the shortage of disease

Fulvic acid chelate trace elements in the formation of strong mobility, easily absorbed by the crop of fulvic acid chelates, to the site of the deficient in crops, effectively solve the lack of disease. Fulvic acid and iron, zinc and other trace elements chelation reaction occurs, resulting in good solubility, easily absorbed by the plant fulvic acid trace element chelate, effectively solve the leaf yellowing caused by iron deficiency.

Improve crop quality

Fulvic acid has the function of surfactant, can reduce the surface tension of water, emulsifying and dispersing pesticides; with a number of pesticides to produce different degrees of hydrogen bonding or ion exchange reaction; early fruit coloring, mature, similar Ethylene ripening effect.

Anti-disease ability

1, fulvic acid directly improve the soil organic matter content, for beneficial microorganisms to provide an excellent environment, benefit the population and gradually develop the dominant populations, inhibit the growth of harmful bacteria, coupled with the plant itself due to the excellent soil conditions and robust growth, disease resistance The ability to strengthen, thus greatly reducing the disease, especially the occurrence of soil-borne diseases.

2, fulvic acid obvious inhibitory effect on fungi, can control many diseases caused by fungi.

3, fulvic acid contains carboxyl, hydroxyl phenolic and benzene carboxylic acid structure, which with some of the phenoxy carboxylic acids, the same as the active ingredient of phenolic pesticides, has some bacteriostatic antiviral effect.

Fulvic acid is the best component of soil humus, which can not only reduce the crop burden, increase soil fertility, enrich soil matrix of bacteria, but also improve crop yield and quality, so as to help farmers to increase production, improve quality, raise land Long-term goal.

Prevention and treatment of bacterial blight

Damping off to wire is withered nuclear bacteria genera and imperfect bacteria caused the door fungal infection, host range, in addition to the solanaceae, melons, vegetables, some vegetables, such as leguminosae, cruciferae can also killed, major hazard seedling stem base or underground roots, do not produce flocculent white mildew, lodging and slow progression of symptoms can be distinguished from damping off, let's together to have a look at prevention and treatment of damping off!

Symptoms of bacterial blight

Damping off in seedling, the middle and late major hazard seedling stem base or underground roots, oval or irregular dark brown disease spot at first, early disease seedling wilting during the day, night recovery, disease gradually sag, excessive shrinkage, some gradients are dark brown, when the disease spot expanding around the stem dry death finally, but no lodging, strain only light brown depression disease spot and not die, seedbed of the disease when humidity is big department is not very obvious hazel spider filamentous fungi.
