The method that apply fertilizer of garlic sprout

Garlic seedling is a common vegetable, garlic seedling cultivation is to harvest seedlings for the purpose, the growth period experienced by the main seedling period, one year can be more stubble cultivation.So how do you fertilize garlic plants?Here to introduce the garlic seedlings fertilization method.

How does garlic sprout fertilize good

During the growth period of garlic seedling cultivation, less fertilizer was needed, but the plant planting density was large and the amount of fertilizer absorption per unit area was large.At the same time, small garlic cloves were used as seed garlic in garlic seedling cultivation.Together with the edible part is false stem (namely leaf sheath part, also called garlic white) and tender leaves, tender and juicy garlic seedlings, taste delicious, so garlic seedlings cultivation fertilization can not be ignored.

Of garlic seedling apply fertilizer is to should apply sufficient base fertilizer, 2 it is not to need crouch seedling, want to urge after all.Base fertilizer can be combined with land preparation, 667 square meters apply ripe circle fertilizer 4000-5000 kg, or human and animal manure 2500-3000 kg, or agricultural fertilizer 5000 kg, plus ammonium bicarbonate 15-20 kg, 50 kg calcium superphosphate as base fertilizer.Generally, the top dressing should be 2-3 times, with quick effect fertilizer and mainly nitrogen fertilizer.

The method that apply fertilizer of garlic sprout

The first topdressing is usually carried out after the seedlings are fully grown, with a total area of 667 square meters for 1000-1500 kg of human excrement and urine, or 10-15 kg of urea;The second topdressing can be conducted about 15 days before harvest, and the application amount can be the same as the first time.If harvest is late, can add between two topdressing to chase fertilizer, topdressing quantity is general 667 square metre apply urea 15-20 kilograms.After the spring harvest, to be combined with water pouring green, green fertilizer, in order to speed up the green, improve the quality and yield of garlic seedlings.

Greenhouse cultivation of garlic seedlings, to prepare fertile soil.Top dressing was mainly carried out through leaf surface.After seedling height 5 centimeters, every square metre is irrigated apply water of 20 grams urea, after every 7 days gute is applied apply solution of 300 times water of 2 ammonium phosphate, after every foliar fertilize, want to use clear water to rinse foliar, lest produce fertilizer to harm.

Above is the introduction of the garlic seedling fertilization method, planting garlic seedling friends, can refer to the above fertilization method, combined with the actual planting conditions, reasonable fertilization.

How to fertilize pineapple effectively?

Pineapple fruit quality, rich nutrition, with heat quenching thirst, xiaoshi zhixie, spleen and stomach tonic, solid vitality, benefit qi and blood, xiaoshi, clearing damp, beauty slimming and other effects, for the summer medicine and excellent seasonal fruit, but also should not eat too much.

1. Base fertilizer: it is the material basis for ensuring good plant growth after planting, and requires large amount of fertilizer, complete elements, high concentration and harmonious proportion.Use manure, compost, soil compost, waste compost, green compost, cake compost after retting processing can be applied, add appropriate amount of chemical phosphorus, potassium, magnesium fertilizer.In red soil and brick red soil with low available phosphorus and low nitrogen and calcium, 3.5-4 tons manure, 150-200 kg calcium superphosphate, l5-20 kg potassium sulfate and 0.8-1 kg magnesium sulfate were applied together with two topsoil and mixed well.

2. Base fertilizer: the basic fertilizer for the growth and development of pineapple in one year is the material condition to ensure the high yield and high quality in the next year. Therefore, it is said that "one base wins three catches".Apply in the first foot or between the lines to open a good fertilizer ditch, the dead leaves, fruit stalks, weeds or green fertilizer pad in the bottom of the ditch, and then apply mixed with two topsoil fertilizer and fertilizer farmers.Generally each mu of soil fertilizer 2-2.5 tons, nitrogen, phosphorus and potassium ternary compound fertilizer 20-25 kg, cake fertilizer 25-30 kg.Earth up immediately after application.

3. Top dressing:

1) strong bud fertilizer.In order to promote the growth of succulent buds, the root soil or the base of petiole was added with water after the fruit was harvested.

2) fat before flowers.Before the differentiation of flower bud, l1 month was applied, 2-2.5kg manure, 20-30g urea and 40-50g superphosphate were applied on each plant to promote the differentiation of flower bud, increase the number of layers of flowers and enhance the cold resistance of the plant.

3) promote bud growth.In January, ditch in the stem base and apply mainly phosphorus and potassium fertilizer, mixed with half of the farm fertilizer, applying 0.8-1kg per plant, to promote the bud hypertrophy and lay a material foundation for increasing the fruit:

4) the strong fruit promotes the bud fertilizer.During the 4-5 months after flowering and small fruit growing period, potassium and phosphate fertilizer were applied, together with a small amount of nitrogen fertilizer, with the amount of fertilizer accounting for l/5 of the annual amount of fertilizer applied, and the dry application at the stem foot furrow or with doule blunt application.

4. Foliar fertilization: due to the special water storage structure and absorption function of the leaves of pineapple, foliar fertilization has a particularly good effect, especially when it is inconvenient to apply fertilizer in the rhizosphere after plant sealing, foliar fertilization is an important way to replenish fertilizer.Nutrition growth period to nitrogen fertilizer, reproductive growth period to potassium, phosphorus for the second, can be sprayed on the surface of the famous big fertilizer bao, dol and calcium fertilizer.In may, June and July, each leaf was sprayed with dol 1-2 times a month, which can significantly improve the sugar content and flavor of the fruit

American white moth control technology

1. Strengthen quarantine: seedlings in the epidemic area are not allowed to be transported outside the region without quarantine or treatment. Active prevention and treatment are carried out in the epidemic area to effectively control the spread of the epidemic.

2, artificial prevention: before the larvae 3 years old, found that the screen screen was manually cut off, and centralized treatment.If the larva is dispersed, the larva will be collected by the method of stringing the grass to the trunk before pupation, and the larva will be collected by a person at regular intervals.

3. Trapping and killing adults: use American white moth sexual attractant or environment-friendly insect attractant to trap and kill adults. Put the decoy core into the trap during the occurrence period of the adult, hang the trap in the forest, directly trap and kill male adults, block the mating of pests, reduce the reproduction rate, and achieve the purpose of eliminating pests.

4, chemical agents: in the larvae damage issue do early detection, early prevention, if there is a larva harms, the area to check it again, timely prevention, drug choice for biological control 0.12 propylene glycol esters algal acid (algae cover), 2.5% efficient cyanogen chloride fluorine chrysanthemum ester micro emulsion 1500 times spray, Bt emulsion 400 times liquid spray, efficient cypermethrin 2.5% ec 1500 times liquid, and can effectively control the pests.

5, biological control: zhou because bees is a new species, native to China, has become the natural enemies of the moths, the little bee can be found in a variety of hidden places pupate fall webworm, spawning parasitic fall webworm, this kind of high efficient, economic, pollution-free has passed the appraisal of bio-control research and technological achievements is the epidemic area accumulates promotion use.

American white moth control technology

Fall webworm is worldwide quarantine pests, nickname the tiger moth, tent caterpillars autumn, autumn act moth, for lepidoptera tiger moth (genera insects, the main harm of fruit trees and ornamental trees, especially for hardwood, the garden trees, economic forest, farmland shelterbelt cause serious harm, such as the first batch of invasive species have been listed in China, let's take a look together fall webworm control technology!

Agricultural control of bacterial blight

1, agricultural prevention and control: strict selection of bacteria free soil with nutrient soil seedling, seedbed soil treatment can be used with 40% chloronitrobenzene and 41% astatine · pyrimethamine mixture, the ratio of 1:1, or with 38% pyrimethyrimethole, each mu dosage of 25 ~ 50 ml, uniform spray on the seedbed.Crop rotation with gramineous crops can reduce the incidence of disease.In autumn, the melon field turned 25 ~ 30 cm deep, and the surface soil bacteria and disease residues were turned into deep soil to decompose.Land leveling, suitable sowing, generally in 5 cm ground temperature stable sown when 12 ~ 15 ℃ advisable.After the emergence of seedlings timely culling disease seedlings, after the rain should be broken by intertillage hardening, in order to improve the ground temperature, so that the soil loose dredging gas, enhance the disease resistance of melon seedlings.

2. Biological control: spray the seedbed with the root type of 2-4 grams per square meter during seedling cultivation. Before and after transplanting, the seedling bed can be diluted by 1500-3000 times with 200ml of root per plant.

3. Seed treatment: the amount of medicine used for seed dressing is 0.2-0.3% of dry seed weight. The commonly used pesticides include seed dressing shuang, Dixon, seedling disease net, rikerella and other seed dressing agents.

4. Pesticide control: at the initial stage of the disease, spray 38% amylpyridamole 800 times liquid, or 41% astatine · pyrimethylamine 600 times liquid, or 20% methyl trichlorphos emulsion 1200 times liquid, or 72.2% prilik water agent 800 times liquid, once every 7 ~ 10 days.Or general + door god by 600 times liquid dilution, 3 liters per square meter before or after sowing and planting seedbed irrigation.At the time of transplanting or after transplanting and before the frequent occurrence of expected diseases, the product was diluted with 600-fold solution and root irrigation was conducted. The medication was given once every 7 days, and The Times of medication were determined by the patient's condition.

The pathogenesis of blight

Mycelium and sclerotium were used to overwinter in soil or diseased tissues, with strong saprophysis, which could survive in soil for 2 ~ 3 years, and was spread by rain, running water, bacteria-bearing compost and agricultural tools.Germs develop warm 20 ~ 24 ℃, unearthed seedlings and went to suffer, more commonly occurs in middle and later periods of the seedling.In the seedling stage bed temperature is higher or in the late seedling, rainy wet, soil is too sticky, heavy stubble disease.Sowing too dense, not timely thinning, high temperature easy to cause the disease.

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.

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!

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.

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.
