Lead to premature aging of vegetables for many reasons, including unreasonable fertilization is one of the important reasons. How to prevent fertile vegetables to prevent premature aging it? Here to tell you about preventing premature aging vegetables fertilization methods.
Premature aging vegetables
Fertilizer topdressing caused by capillary root injury, do not pay attention to balanced fertilization caused by excessive or weak plant growth, etc., may lead to plant premature aging. Therefore, scientific and rational fertilization is an important measure to prevent premature aging of vegetables. Friends of farmers in the fertilization should pay attention to the following questions:
1. Spring pick-up, still can not increase the amount of fertilizer. Fertilization must be based on the law of need for fertilizer for each crop to be used reasonably to avoid vegetable root injury caused by over-fertilization of chemical fertilizers, leading to premature aging of plants. General topdressing of 15-20 kg of compound fertilizer per acre with bio-fertilizer 30-40 kg is appropriate.
2. Pay attention to balanced fertilization. Such as the lack of potash fertilizer peak results, not only will affect the yield and quality of vegetables, can also cause premature plant failure. Therefore, fertilization must be based on the needs of each crop growth period of the fertilizer needs a reasonable match, in order to make the crop without stubble, no premature decline.
3. Avoid the application of hormones containing fertilizers. In particular, immediately after the application of fertilizer can often lead to plant premature aging. Farmers in the purchase of fertilizer, such "fertilizer is particularly significant" fertilizer must be carefully selected.
How to properly fertilize vegetables to prevent premature aging
4. Spring still pay attention to the application of biological fertilizer. Due to the improvement of soil structure, soil fertility and the suppression of soil-borne diseases, bio-fertilizer is undoubtedly a good fertilizer for curing plant roots and delaying plant senescence. In the production, biological fertilizers must pay attention to cooperation.
5. Pay attention to the use of foliar fertilizer. Some foliar nutrients can alleviate plant deficiency symptoms, often foliar spray can significantly improve plant growth, especially in late vegetable growth, can significantly delay plant aging.
The above is to prevent premature aging fertilization of vegetables introduction, farmers friends in the fertilization time, you can refer to the above methods, combined with the actual planting situation, according to local conditions, a reasonable fertilization.

India's water treatment chemicals average annual growth rate of 6.4%
Indian water treatment chemicals include specialty chemicals and household chemicals in two broad categories. Special chemicals mainly pH regulator, water softener, defoamers and defoamers; daily chemicals are mainly coagulants, flocculants, fungicides and disinfectants.
In 2009, the Indian water treatment chemicals industry reported sales of Rs. 225.3 crore, of which specialty chemicals revenue was Rs. 232 crore, accounting for only 1/10 of the total water treatment chemicals. Frost & Sullivan expects the water treatment industry in India to have an average annual growth rate of 6.4% from 2009 to 2016 and total industry output to reach 44.8 billion rupees by 2015. In the next five years, the growth rate of special chemicals will far exceed the growth rate of daily chemicals.
The report pointed out that India's water treatment chemicals market is now nearing maturity, but the market is highly fragmented, more than 300 manufacturers compete for market share, competition is fierce. Competition will intensify as more and more new players enter the market.
In addition, a number of large conglomerates have also entered the Indian water treatment market for chemical outsourcing operations, including GE Water and WaBag. These manufacturers have set up factories in India to provide better quality, more cost-effective products and longer service life.
The company believes that the main factors that promote the development of water treatment chemicals in India lies in the following aspects: First, the population factor. The population of India is projected to grow to 1.66 billion by 2050, and the rapidly growing population is one of the major drivers of India's water treatment chemicals market. There is no doubt that an increase in population will further increase the demand for domestic and industrial water in India. Second, industrial development will surely promote the development of the water treatment chemicals market in India, as water treatment chemicals are required for the growing industrial and industrial wastewater. Third, the implementation of various environmental standards will effectively improve the Indian environmental level, thus promoting the development of water treatment chemicals market. For example, the current Indian water resources suspended pollutants, dissolved impurities and trace chemicals and other standards are more stringent than before. Fourth, the role of low-cost alternatives. At present, most of India's most common chemicals are sold at a low price of Rs 5-15 / kg, providing the possibility for manufacturers of second- and third-line water treatment chemicals to make alternatives to water treatment chemicals. The use of alternatives will play an important role in promoting the water treatment chemicals market in India over the next three years.
At the same time, India's water treatment chemicals industry is also facing some adverse factors. In smaller cities and remote areas of India, laws and regulations are being enforced to a lesser extent, especially in wastewater treatment; inadequate infrastructure for sewerage systems in India has resulted in the treatment of only 26.8% of domestic wastewater and 60% of industrial wastewater. In addition, the government agency managing water resources in India is too bloated and its lack of cooperation and communication hinders the development of the water treatment chemicals industry in India to a certain extent.

Food safety rumors harm.
Food safety is a typical microcosm of the new challenges and problems now facing Chinese society. Public consumption confidence index dropped, attaches great importance to frequent heavy accusations of food safety supervision, becoming the most prominent social performance of China's food safety issues. Zhang Yong, director of the State Food and Drug Administration, pointed out in the "13th Five-Year Plan" preparation work that the food and drug safety is a major basic livelihood issue. The Central Party Committee and the State Council have always attached great importance to this. In particular, after the institutional reform, the regulatory tasks have increased substantially, the regulatory resource gap has been further enlarged, and the regulatory power needs to be raised urgently. The global demand for food safety is getting higher and higher, and all countries and the industry are taking active actions. The premier of the State Council said: "Food is the world, food safety first, food safety is related to the people's health and life safety, economic development and social harmony .We want to establish a complete and systematic implementation of the main responsibility for enterprise food safety , Improve food safety standards, strengthen inspection and testing, strengthen food safety supervision and strengthen self-discipline of the industry.2018 Shanghai Food Safety Exhibition will lead the industry trends and will focus on food safety supervision, food safety and biotechnology, microbiology and life sciences, testing Analysis and control, retrospective technology is the largest professional event not to be missed in the five major sections of the exhibition, which is dedicated to promoting innovation and commercial development in all branches of the industry and attracting experts and scholars from all over the world in scientific research and food fields.

Eight, can kill: belong to copper hydroxide, trade name, also known as crown bacteria copper, Feng security, blue shield and so on. In vegetables can be used to control bacterial diseases. Because of its strong protective effect, before the onset can be used to control fungi, Oomycetes disease. Because it is alkaline and inorganic copper, it can only be used with a stable structure of organic fungicides, such as chlorothalonil and so on. And can not be mixed with acidic drugs. It is also not appropriate to mix medications containing metal ions and foliar fertilizer. For mixed with the chemical reaction of the United States and the United States, thiophanate-methyl, carbendazim, diethofen, etc. also should not be mixed, after the mixture of precipitation, condensation and other colloid damage should also avoid mixing, it is not clear should be Test again to determine, so as to avoid a drug injury.
Nine, deuterin Zinc: can prevent a variety of fungal diseases, but the role of powdery mildew is poor. Prevention and treatment of early blight, late blight, spot blight, leaf mold, anthracnose, gray mold, eggplant sponge blight, brown-spot disease, etc., pay attention to squash vegetables sensitive to zinc, medication should strictly control the concentration can not be too large .
Ten, Cheson zinc: is a broad-spectrum, quick-acting protective fungicide. Other names 安泰生. Cabbage downy mildew prevention and control, cucumber downy mildew, tomato disease sooner or later, PTS Zinc is a protective fungicide, must be in the disease before or during the onset of spraying. Do not mix with copper and alkaline agents.
Cymbidium Cyanide: The mechanism of action and features are mainly to prevent the spore germs of pathogenic bacteria, the host bacteria also have a killing effect on the host. It has protective, therapeutic and systemic effects and is effective against downy mildew and blight. Cyclocarbamide alone with short duration of efficacy, and protective fungicides such as propineb mixed with zinc, can extend the duration. Suitable for crop cucumbers, grapes, peppers, potatoes, tomatoes and so on. Control objects downy mildew and disease.

Celery soil testing and fertilization technology
Celery is one of the most common green vegetables, rich in a variety of nutrients. In celery planting process, fertilization is an important work, celery fertilization methods and ways there are many. Today to tell us about celery soil testing and fertilizer technology.
celery
To be celery nutrient growth peak nutrient uptake, the period of nitrogen, phosphorus, potassium, magnesium, calcium absorption of five elements accounted for more than 84% of the total absorption. Celery need nitrogen highest, followed by calcium and potassium, phosphorus, magnesium at least. Celery is also a great demand for boron in the boron-deficient soil or due to drought and low temperature inhibition of absorption, the petiole is prone to transverse rupture, that is, "stem folding disease," seriously affecting the yield and quality.
Fertilizer medium fertility level of celery throughout the growth of fertilizer per acre for the farmhouse 2500-3000 kg (or organic fertilizer 350-400 kg), nitrogen fertilizer 13-16 kg, phosphorus fertilizer 5-6 kg, potassium 6-9 kg, nitrogen , Potassium base fertilizer and three top dressing, fertilizer ratio 2: 3: 3: 2, all phosphate fertilizer for basal, fertilizer and manure (or commercial organic fertilizer) mixed application.
Basal fertilizer applied per mu farm 2500-3000 kg or 350-400 kg of organic fertilizer, urea 4-5 kg, 11-13 kg of diammonium phosphate, potassium 4-5 kg.
Celery soil testing and fertilization technology
Topdressing seedlings in the Huanmiao Mushi urea growth rate of 6-8 kg, 3-4 kg of potassium sulfate; vigorous growth of the early Mushi urea 8-11 kg, 3-5 kg of potassium sulfate; vigorous growth of mid-term Mushi urea 6- 8 kg, 3-4 kg of potassium sulfate.
Root top dressing such as heart rot found available 0.3% -0.5% calcium nitrate or calcium foliage spray. Foliar application of boron fertilizer to a certain extent to avoid the occurrence of stem split, spraying 0.2% per acre borax or boric acid solution 40-75 kg. Facility cultivation can increase the carbon dioxide gas fertilizer.
Above is celery soil testing and fertilizer technology, planting celery friends can refer to the above method, combined with the actual planting situation, rational use of soil testing and fertilizer technology.

How to fertilize cotton to high yield?
With the cotton planting methods and technological advances, fertilization methods also need to make the appropriate changes, how to fertilize cotton to high yield it? Here to tell you about cotton fertilization skills.
How to fertilize cotton to high yield
In recent years, the introduction of a large number of insect-resistant cotton around the effective control of the harm of bollworm, ray ban, the number of fallen buds greatly reduced, reproductive growth strong, bell earlier and more, to be fat peak faster and fierce. If the traditional methods of fertilization, often can not meet their needs, resulting in poor nutrition and premature aging. In addition, insect-resistant cotton because of the introduction of insect-resistant genes, its resistance to decline, prone to leaves, stem blight and other diseases.
Increasing the amount of nitrogen and nitrogen fertilizer reduction
Potassium fertilizer has the function of cotton stress resistance and disease prevention, therefore, need to increase the application of potash fertilizer. If blindly adding nitrogen and phosphate fertilizer, ignoring the application of organic fertilizer and potassium fertilizer will not only increase the cost of fertilization, but also lead to premature or late cotton, affecting the yield and quality greatly.
Increase of organic fertilizer, potash, reduce nitrogen, phosphate fertilizer operations are as follows: Mushi about 3000 kilograms of organic fertilizer, potassium 10-15 kilograms. From the traditional acres of urea 25-30 kg of urea, 50 kg of superphosphate, reduced to 12 kg urea mu, superphosphate 25 kg. The above fertilizers, combined with deep soil facilities 15 cm below.
What are the principles of cotton fertilization
Flower boll fertilizer once concentrated to two facilities
Flower boll cycle is the most vigorous growth and development of cotton throughout the life, the need for the most time, need to re-Huaping fertilizer. Generally need acres of urea 25-30 kg, potash 10 kg. Bunch cotton boll fast and concentrated for the characteristics of cotton boll fertilizer can be 2/3 initial flowering, the remaining 1/3 about 15 days and then chase, so that can not only meet the cotton flowering bell Needs, but also can effectively prevent the growth and decline of cotton plants.
Cover top soil top dressing changed to foliage
Late cotton growth, the absorption capacity of the root decline, if insufficient nutrients, can easily lead to premature aging, the need to top-cover fertilizer. Top dressing foliar fertilizer has the advantages of simple, quick, good effect, fertilizer and other advantages, can save 2/3 than the soil topdressing fertilizer.
The above is some introduction of cotton fertilization techniques, planting cotton friends can refer to the above methods, combined with the actual planting situation, the rational fertilization.

Environmental problems that exacerbate water pollution
Take water pollution as an example.
In the past ten years, Jilin Songhua River pollution incident, Fujian Zijin Mining pollution incident, Guangxi chromium pollution incident, a large area of Taihu Lake cyanobacteria outbreak, a large area of Dianchi Lake cyanobacteria outbreak, one by one water pollution incident all touch the nerves of ordinary people, How to drink a healthy, safe, clean and good water, become the hot topic of the whole society.
The year 2013 just passed is another year of water pollution incidents.
First, in March, the incident that shocked the entire country in Shanghai's Huangpu River floating 10,000 dead pigs caused panic in Shanghai and the surrounding area. Henan Xinxiang appeared to use untreated paper-making wastewater to irrigate the wheat fields. Then there was another reporter who broke the news that part of Shandong Weifang Chemical enterprises and paper mills use high-pressure water wells to discharge sewage to the underground. In April, Dongjiang District, Kunming City, Yunnan Province also screened the milk river. The tailings water discharged by the local industrial and mining industries was directly injected into the rivers and polluted for many years. Water and soil pollution ...
In May 2013, according to a survey released by the State Environmental Protection Administration, the overall quality of shallow groundwater in the North China Plain was generally poor with almost no Class I groundwater; Class I-III groundwater, which can be directly consumed, only accounted for 22.2% Grade V groundwater available after treatment accounted for more than 56.55%. Due to serious groundwater pollution, villagers in Tianjin Zhai Zhuang Zi only drink 0.5 yuan per pot for the past three years for water supply, and the well water in the village is only used to wash the pot and wash clothes.
According to the "Land and Resources Bulletin" released by the Ministry of Land and Resources in June 2013, there are currently 4929 groundwater quality monitoring points in 198 municipalities and autonomous regions throughout the country, of which there are 1999 monitoring points in which the comprehensive evaluation of water quality is of poor quality and the water quality There are 826 monitoring points of very poor level. 40% of groundwater monitoring point of poor water quality, good grade water quality accounted for only 11.8%. Iron, manganese, fluoride, "three nitrogen" (nitrite nitrogen, nitrate nitrogen and ammonium nitrogen), total hardness, total dissolved solids, sulfate, chloride and other monitoring points are the main oversupply component, and individual monitoring points There are still heavy (class) metal project exceeded the standard.
Water pollution and frequent accidents have seriously threatened people's normal life and the continuous development of agriculture and industry.
EU released lycopene assessment report
On December 1, 2017, the European Food Safety Authority (EFSA) released the assessment report on the expansion of lycopene (E 160d) as a food additive for certain meat products and fruit and vegetable products. Applicants should apply multiple times. The group Evaluate and conclude:
It is recommended that lycopene (E160d) be used as a food additive in meat, fruit and vegetable products at a limit of 60 mg / kg but at this limit total food additive intake may exceed current ADI; Uncertainty, the Panel recommends further precise assessment.
How to use pesticides Scientific use of pesticides (b)
Five, tomato gray leaf spot per 667 square meters can be used 15% grams of fungicide smothering agent (gram Kling Ling Qing bacteria) 200 grams smoked.
Sixth, how to control tomato leaf mold disease: (1) broad-spectrum fungicide: such as chlorothalonil (merken), fluhexin (iprodione), thiophanate-methyl and so on. The advantages of such agents are: broad spectrum prevention, safety, low prices, good preventive effect. The disadvantage is: poor treatment. It should be used before the onset, or with the treatment of prominent drug use. (2) azole drugs: such as myclobutanil (cents), triflumizole (Teflon), difenoconazole (World Health), the advantages of significant therapeutic effect, low dosage, strong absorption, Long-lasting, the disadvantage is: the amount of the general assembly to curb the growth of crops. If more than three consecutive doses, it is likely to cause tomato leaves smaller, harden, brittle, black and so on, it should be used with caution, especially in the cold period of winter to use less, except for the world height. In the use of such agents can be used with some growth regulators, such as brassinolide (Shi Taiyuan, Yun-120, etc.), cytokinin and other use, in order to reduce its inhibit tomato growth side effects. (3) antibiotic agents: such as kasugamycin, polymyxin, agricultural anti-120, the advantages of these agents are: safe, broad-spectrum, strong absorption, the prevention effect is outstanding, but the treatment effect is poor. Based on the characteristics of the aforesaid medicaments, the following medicaments should be used when preventing and controlling tomato leaf mold with medicaments: when there is no spot on the leaf or the incidence is less than 5%, broad-spectrum bactericides, or world-scale, or antibiotic- Can also be mixed use. When the incidence is higher than 5%, and there is a trend of spread, the azole fungicide should be used. Of course, you need to use with brassinolide, cytokinin and other plant growth regulators. When the disease is particularly serious, the azole drugs can be mixed with broad-spectrum drugs or antibiotics to prevent and treat the disease.
Seven, amoxicillin: azoxystrobin, amoxicillin bactericidal spectrum is very broad, the four major types of pathogenic fungi: Ascomycetes, Basidiomycetes, half-know bacteria and oomycetes in most of the pathogens All valid. A drug treatment of multiple diseases is the prominent features of Amistar, and the role of the existing fungicides different ways, high activity, the current resistance of bacteria to amisiaca weaker. Its strongest advantage is to prevent protection, not its therapeutic effect.
Its preventive and protective effect is ten times to several times that of ordinary protective bactericide, and its therapeutic effect is almost not much different from that of ordinary systemic therapeutic bactericide. Therefore, to give full play to the effect of amoxicillin, must be used before or during the onset of disease. When the incidence of severe use of amoxicillin, disease prevention and other systemic fungicide will not be significantly different. In order to give full play to the effectiveness of Amistar for disease prevention and production enhancement, it is most appropriate to use Amistar for the following three periods based on the experiences of different places. The first is to use seedlings at the seedling stage; the second is at the pre-flowering stage; Third, the early fruit growth. Adequate water spray is also an important factor in ensuring the effectiveness of Amistar. In Shouguang, a greenhouse of 50-60 meters in length should be sprayed with at least 4 sprays of water (120 pounds) at adult plants (tomatoes, cucumbers, eggplants, bell peppers) and 6-7 sprays of water at 80 meters of sheds. The use of concentrations are 1500 times the liquid (add 1 pack of water per atomizer Amistar), each spray interval of 10-15 days, with a spray 2-3 times. Amitage general single, we must pay attention.
Sixth, how to control tomato leaf mold disease: (1) broad-spectrum fungicide: such as chlorothalonil (merken), fluhexin (iprodione), thiophanate-methyl and so on. The advantages of such agents are: broad spectrum prevention, safety, low prices, good preventive effect. The disadvantage is: poor treatment.

A drug treatment of multiple diseases is the prominent features of Amistar, and the role of the existing fungicides different ways, high activity, the current resistance of bacteria to amisiaca weaker. Its strongest advantage is to prevent protection, not its therapeutic effect.
Its preventive and protective effect is ten times to several times that of ordinary protective bactericide, and its therapeutic effect is almost not much different from that of ordinary systemic therapeutic bactericide. Therefore, to give full play to the effect of amoxicillin, must be used before or during the onset of disease. When the incidence of severe use of amoxicillin, disease prevention and other systemic fungicide will not be significantly different. In order to give full play to the effectiveness of Amistar for disease prevention and production enhancement, it is most appropriate to use Amistar for the following three periods based on the experiences of different places. The first is to use seedlings at the seedling stage; the second is at the pre-flowering stage; Third, the early fruit growth. Adequate water spray is also an important factor in ensuring the effectiveness of Amistar. In Shouguang, a greenhouse of 50-60 meters in length should be sprayed with at least 4 sprays of water (120 pounds) at adult plants (tomatoes, cucumbers, eggplants, bell peppers) and 6-7 sprays of water at 80 meters of sheds. The use of concentrations are 1500 times the liquid (add 1 pack of water per atomizer Amistar), each spray interval of 10-15 days, with a spray 2-3 times. Amitage general single, we must pay attention.
How to use pesticides Scientific use of pesticides (a)
In recent years, with the continuous improvement of people's living standards, the demand for vegetables and fruits has also been constantly improved. It is necessary that these vegetables and fruits are sold well, fresh and delicious, and they also want to eat healthy vegetables in the body without any pollution. No harm, especially for the latter's request even worse, there are still many people in the purchase of such goods will be selected when there are some minor insects moth phenomenon, that such vegetables or fruits are not sprayed pesticides, after eating the body No damage. It can be seen that modern people pay more and more attention to the improvement of their quality of life. How to use pesticides on the fruits and vegetables they planted and how to use pesticides scientifically and reasonably has become a concern for modern growers. The following specific to understand: how to use scientific pesticides.

Humus acid whole solution!
Humic acid is a kind of organic matter that is caused by and accumulates in the remains of plants and animals, mainly the remains of plants, through the decomposition and transformation of microorganisms, and the series of geochemical processes. Its total is staggering, trillions of tons. Rivers and lakes, soil, coal mines, most of its surface has its traces. Because of its widespread existence, the impact on the Earth is also great, involving the carbon cycle, the accumulation of mineral migration, soil fertility, ecological balance and so on. Soil contains the largest amount of humic acid, but less than 1% on average, and fresh and brackish water contains less total but lower concentrations.
Humic acid is a good biological activity. The organic carrier composed of many kinds of functional groups is also an intermediate with the metabolic function of plant respiration and photosynthesis, so it has great capacity and can be combined with many kinds of materials. Humic acid and pesticides are mainly combined by the way of ionic bond, hydrogen bond, proton transfer, electron transfer, complexation and other interactions to form a new type of pesticide polymer complex, which is the humic acid environmental pesticide. Research and practice show that humic acid and insecticides, fungicides, herbicides compound, can play a role in enhancing efficacy and reduce toxicity.
Specific performance:
- solubilization: humic acid can play a role as a surfactant, the surface tension of the metal salt is lower than the surface tension of water, the pesticide can produce significant dispersion and emulsification effect, can improve the solubility of soluble pesticides;
- Synergism: Humic acid can enhance plant absorption of pesticides, can improve the biological activity of pesticides and plant growth regulators, can significantly improve the effect of pesticides;
- Slow release: Humic acid has a significant inhibitory effect on the decomposition rate of pesticides, and the greater the amount of humic acid, the slower its rate;
- Detoxification: Humic acid can passivate biological activity of those susceptible to pesticide-sensitive enzymes, to stimulate the activity of antagonistic enzymes to pesticides to alleviate and reduce the toxicity of pesticides.
Organic-inorganic fertilizer as a new type of fertilizer, is becoming the 21st century ecological agriculture with fertilizer development. Here mainly discusses the fertilizer humic acid in agricultural applications.
A. The use of humic acid can change the soil salt is too high, alkaline is too strong, highly dispersed soil particles, poor soil structure of physical and chemical properties, promote the formation of soil aggregates, make it into good condition, so as to plant root growth Develop and create good conditions.
B. Application of humic acid can loose topsoil, destroying the accumulation of salt, reducing the amount of salt in the topsoil, play a salt effect, improve the emergence rate, reduce the weak seedlings, dead seedlings, so that plants grow healthily.
C. Humic acid has a high cation conversion, more than 10 times higher than the average soil. After applied to the soil, so that the soil adsorption capacity of anion significantly increased, so that the surface salt content decreased.
D. Saline-alkaline soil, especially alkaline soil PH value is too high (9.0 above), directly endanger crop growth and even cause death, and the other PH value also affects the soil phosphorus, iron, manganese, boron, zinc and other nutrients Effectiveness. Humic acid PH value of 6.8 acidic, alkaline and neutralization can reduce the harm of alkalinity on the soil and plants, so that low-yielding saline-alkali so as to create good soil conditions for crop seedling growth.

How to fertilize garlic?
Garlic fertilizer has always been the focus of attention of many garlic farmers friends, how to give garlic how to fertilization? Today we will introduce garlic fertilization methods.
Garlic fertilizer
Garlic can be growth and development needs and fertilizer, fertilizer characteristics of fertilizer, garlic should be based on organic fertilizer, supplemented by chemical fertilizers; mainly based fertilizer, supplemented by the principle of top dressing to meet the garlic growth and development process The need for nutrients.
Garlic base fertilizer is best to organic fertilizer. Common organic fertilizer loop fat, chicken manure, duck manure, manure, compost, cake and so on. Whether the application of basal fertilizer is sufficient is directly related to the commerciality of garlic and garlic and the overwintering performance of the plants, so the application of adequate basal fertilizer should be implemented in production.
Basal fertilizer application rate should be based on the target yield of garlic and yield per unit area of the amount of fertilizer and other factors to be considered. Conditional application of cotton seed cake pie 50-100 kg. Combined with organic fertilizer for basal application of fertilizer are usually superphosphate, nitrogen and phosphorus fertilizer, nitrogen and potassium fertilizer or ternary compound fertilizer. Every 667 square meters of standard nitrogen fertilizer about 75 kg.
Nitrogen fertilizers have 2/3 for basal application, 1/3 for top dressing. Most phosphorus, potassium fertilizer for basal application.
Phosphate fertilizer used about 30 kilograms of superphosphate. Phosphate fertilizer for basal application, whether it is superphosphate, or calcium magnesium phosphate fertilizer, should be mixed with organic fertilizer, shallow tillage into the tillage. The amount of potassium fertilizer application, generally about 66 kilograms of potassium sulfate applied about 30 kg.
Basal application of fertilizer is generally half of the organic fertilizer applied before arable land, spread evenly on the soil surface, combined with arable land, the fertilizer into the ground; the other half in the sowing, the focus of ditch facilities, and fertilizer, soil Mix and sow. Such as ammonium bicarbonate or organic fertilizer for the basal fertilizer, to trenching buried, or with water facilities, combined with land preparation after the fertilizer and soil mixed.
Phosphate fertilizer is the best application of shallow facilities, centralized facilities or stratification facilities. One can be applied before a part of arable land, the other part of the cultivation after planting garlic, or in the ground after the shallow facilities in the ground 6-10 cm Department to facilitate the absorption and utilization of seedlings, nurturing strong seedlings, improve seasonal utilization of phosphate fertilizer. Potash can be used in arable land, with the spread of farmland, turn into the ground can be.
The above is the introduction of the method of garlic fertilization, garlic farmers friends can refer to the above methods, combined with the actual planting situation, scientific fertilization.
