Water-soluble fertilizer: rich in nutrients to promote growth, water-saving and fertilizer-saving

Water-soluble fertilizer is a kind of multicomponent compound fertilizer which can be completely dissolved in water, which can be quickly dissolved in water and can be easily absorbed by crops, and its absorption and utilization rate is relatively high. what is more important is that it can be used in facility agriculture such as spray and drip irrigation. realize the integration of water and fertilizer, and achieve the efficiency of saving water, fertilizer and labor. The use of water-soluble fertilizer is simple and convenient. First of all, people can design the formula according to the characteristics of nutritional requirements for crop growth, and the scientific formula will not cause a waste of fertilizer. as a result, the fertilizer efficiency is almost 2-3 times that of conventional compound chemical fertilizers. Secondly, water-soluble fertilizer is a quick-acting fertilizer, which allows growers to quickly see the effect and performance of the fertilizer, and the fertilizer formula can be adjusted at any time according to the growth of crops. Of course, the application method of water-soluble fertilizer is very simple, it can be fertilized with irrigation water, including sprinkler irrigation, drip irrigation and other ways of irrigation, which not only saves water, but also saves fertilizer, but also saves labor. Today, with the rising labor costs, the benefits of using water-soluble fertilizers are obvious. Because the application method of water-soluble fertilizer is irrigated with water, so the fertilization is very uniform, which also lays a solid foundation for improving yield and quality. Water-soluble fertilizer is generally less impurities, low electrical conductivity, easy to adjust the concentration, so it is safe even for young seedlings, do not have to worry about burning seedlings and other adverse consequences. Because the all-water-soluble fertilizer has the characteristics of simple and easy to use, it has been widely used all over the world. In foreign countries, it is widely used in irrigation and fertilization of vegetables and flowers in greenhouse, all kinds of fruit trees and field crops, the maintenance of landscape greening plants, golf courses and even family greening plants. In China, its high price has affected the acceptance of it by Chinese farmers, but in recent years, due to the rapid development of Chinese flower industry and ornamental horticulture, it has also been accepted by the majority of Chinese professional growers, used for potted flowers, grass flowers, flower cultivation, and even some golf courses. To achieve accurate proportion, to provide reasonable N, P, K and trace elements to balance plant growth; to achieve reliable professionalism, to provide different special fertilizers for different plants, growth periods and water quality. Special addition of super exhibition agent and penetrating agent, good dispersion, fast absorption, improve the absorption and utilization of various nutrients. Water-soluble fertilizer has been widely promoted in China, water-soluble fertilizer is mainly cash crops such as vegetables, fruits and fruit trees in Guangxi, so water-soluble fertilizer has been widely popularized in Guangxi economic crop area in recent seven or eight years. The vegetable greenhouse households in Shouguang City, Shandong Province basically use water-soluble fertilizer, which can improve the soil quality in the greenhouse and the quality of vegetables. Apple is the main cash crop in Qixia City, Shandong Province, and the effect of water-soluble fertilizer on fruit trees is very good through fixed-point experiments. In recent years, the use of water-soluble fertilizer in fruit trees has developed rapidly. In apple-producing areas of Jiaodong Peninsula, Shaanxi apple-growing areas, Guangxi citrus and banana producing areas, water-soluble fertilizer can greatly improve fruit quality, achieve the purpose of increasing production and income, and bring a big surprise to fruit growers. With the continuous innovation of production technology, in terms of crop nutritional requirements, the era of increasing production by massive application of ternary compound fertilizer granulation chemical fertilizer has passed, because water-soluble fertilizer contains all the nutrient elements needed for crop growth. it can meet the purpose of increasing production and income of farmers. It is also the need of the development of the times to popularize basic professional water-soluble fertilizer, change farmers' traditional fertilization habits and promote the integrated development of water and fertilizer. According to the statistics of the chemical industry, by the end of the first half of 2011, more than 200 chemical fertilizer production enterprises had put on record with the Ministry of Agriculture to produce water-soluble fertilizers. A total of 3433 water-soluble fertilizers have been registered in China, including 433 large-element water-soluble fertilizer products, 50 medium-element water-soluble fertilizers, 1195 trace element water-soluble fertilizers and 1010 amino acid water-soluble fertilizers. There are 745 water-soluble fertilizers containing humic acid. In 2010, the national output of water-soluble fertilizer was 400000-600000 tons, a substantial increase of more than 50% over the previous year. At present, the state has issued relatively perfect product quality standards for a large number of element water-soluble fertilizers, trace element water-soluble fertilizers, amino acid water-soluble fertilizers and humic acid water-soluble fertilizers, which clearly defines the effective ingredients, packaging specifications, label production and commodity names of all kinds of products, as well as normative requirements for the use instructions of the products. Scientific and reasonable standard for the rich proportion of a large number of elements in water-soluble fertilizers: according to the standard of the Ministry of Agriculture of the people's Republic of China (NY1107-2010), a large number of elements in water-soluble fertilizers (medium elements) solid products, the main technical indicators the content of a large number of elements ≥ 50.0%, the content of medium elements ≥ 1.0%. Large amount of element water-soluble fertilizer (medium element type) liquid products, the main technical indicators large element content ≥ 500g/L, medium element content ≥ 10g/L. Among them, the content of a large number of elements refers to the sum of the total N, P2O5 and K2O contents, and the product should contain at least two large amounts of elements, with a single large element content of not less than 4.0% (40 g per kilogram). The content of medium elements refers to the sum of the contents of calcium and magnesium, and the product contains at least one medium element, and a single medium element with a content of not less than 0.1% (1 g L) shall be included in the content of medium elements. A large number of elements water-soluble fertilizers (trace elements) solid products, the main technical indicators the content of a large number of elements ≥ 50.0%, the content of trace elements is 0.2% UV 3.0%. A large number of elements water-soluble fertilizer (trace element type) liquid products. Among them, the content of a large number of elements refers to the sum of the total N, P2O5 and K2O contents, and the product should contain at least two large amounts of elements, with a single large element content of not less than 4.0% (40 g per kilogram). The content of trace elements refers to the sum of the contents of copper, iron, manganese, zinc, boron and molybdenum, and the product should contain at least one trace element with a content of not less than 0.05% (5 g per cent). The content of molybdenum element is not more than 0.5% (5 g inch L). Application characteristics: a large number of element water-soluble fertilizers are rich in 12 necessary nutrient elements for crops, which are scientifically and reasonably proportioned and applied continuously, which can not only ensure high yield and good quality, but also effectively enhance plant resistance and reduce the occurrence of diseases. it can greatly improve the absorption and utilization of fertilizer. A large number of element water-soluble fertilizers can be flushed and drip irrigation can also be used as foliar fertilizer, the whole process of topdressing does not need to apply other fertilizers, saving the trouble of fertilizer selection. According to the requirements of crops, a large number of element water-soluble fertilizers must have the following technical characteristics: 1. The water-soluble chelated trace element composition should avoid antagonistic effect with phosphorus element. 2. For crops, it has the characteristics of stress resistance and yield increase, which can significantly improve crop photosynthesis, improve crop yield and quality, increase sugar content, enhance stress resistance such as cold resistance, drought resistance, disease resistance and lodging resistance, and prolong shelf life. 3. The addition of high potassium formula can quickly meet the demand for potassium during fruit and grain expansion, increase fruit sweetness, improve fruit coloring and prolong storage time. Principle of natural macromolecule organic matter containing humic acid: humic acid is a kind of natural macromolecule organic compound, which contains many kinds of active genes such as carboxyl group, phenolic hydroxyl group, methoxy group and so on, so it has strong physiological activity. It can react with heavy metal ions such as combination, replacement, complexation, chelation and so on to modify it and form a variety of new substances (new products) with a variety of beneficial properties. Water-soluble fertilizer containing humic acid is a kind of multi-functional fertilizer. at present, there are mainly two ways to combine humic acid and water-soluble fertilizer products: one is the combination of humic acid and water-soluble fertilizer of a large number of elements. humic acid can achieve unitary fusion, binary fusion or ternary fusion with a large number of elements of nitrogen, phosphorus and potassium, such as humic acid nitrogen fertilizer, humic acid phosphate fertilizer, humic acid potassium fertilizer and humic acid compound fertilizer. The standard of water-soluble fertilizer containing humic acid is NY1106-2010. Application characteristics: first of all, water-soluble fertilizer containing humic acid can stimulate crop growth. The stimulating effect of humic acid foliar fertilizer is mainly shown in that it can promote seed germination, increase seed emergence rate, promote root growth, improve the ability of root system to absorb water and nutrients, increase tillers or branches, and mature earlier. Second, improve the physical and chemical properties of soil and improve soil fertility. When humic acid fertilizer is applied to the soil or soil, it can also improve the soil and improve the fertilizer efficiency. Because humic acid organic colloid in humic acid fertilizer combines with calcium ion in soil to form flocculent gel, this colloid is a good cementing material, which can cement soil particles and increase the structure of water-stable aggregates in soil. so as to improve the water, fertilizer, oxygen and heat status of the soil. Provide nutrients for crops. The fertilizer can absorb ammonium ion, potassium ion, calcium ion, magnesium ion and zinc ion, and can form iron and aluminum complex with free iron ion and aluminum ion in acid soil, reduce the fixation of phosphorus and improve the utilization rate of fertilizer. Third, promote the reproduction and activities of microorganisms. Humic acid can stimulate microorganisms, improve the activity of fungi, bacteria and nitrogen-fixing bacteria, promote the decomposition of organic matter, accelerate the ripening of farm fertilizers, and promote the release of available nutrients. Standard for trace element water-soluble fertilizer to enhance crop disease resistance: according to the standard of the Ministry of Agriculture of the people's Republic of China NY1428-2010, trace element water-soluble fertilizer solid product, the main technical index trace element content ≥ 10.0%; liquid product, main technical index trace element content ≥ 100g/L. Among them, the content of trace elements refers to the sum of copper, iron, manganese, zinc, boron and molybdenum, and the product should contain at least one trace element. A single trace element with a content of not less than 0.05% (0.5g/L) shall be included in the content of trace elements. The content of molybdenum is not more than 1.0% (10 g / L) (except for products containing trace elements containing molybdenum). Application characteristics: trace element water-soluble fertilizer refers to multi-element compound fertilizer which can be completely dissolved in water. Compared with traditional calcium superphosphate and granulation compound fertilizer, water-soluble fertilizer has obvious advantages. Its main characteristics are low dosage, low cost, fast absorption of crops and high utilization rate of nutrients. The rational use of trace element water-soluble fertilizer on vegetables plays a good role in improving the yield and quality of vegetables and enhancing the disease resistance of vegetables. In the single element experiment, boron has a very good effect on increasing fruit, increasing fruit setting rate and increasing fruit compactness. Zinc has a good effect on improving the disease resistance of crops, maintaining the biological activity of plant cells and improving the effect of spraying pesticides on crops. Copper can better maintain the cell osmotic pressure of vegetable crops, so that the enzyme metabolism, photosynthesis and respiration in crop cells can be carried out better. In a word, trace elements are of great significance to the healthy growth of vegetables themselves. The principle of reducing residue and promoting environmental protection of water-soluble fertilizer containing amino acids: amino acids exist in fertilizer as the smallest molecule of protein, which is easy to be absorbed by crops; it also has the function of improving disease resistance and improving crop quality. Supplement the essential amino acids of plants, stimulate and regulate the rapid growth of plants, promote the healthy growth of plants and promote the absorption of nutrients. Enhance plant metabolic function, improve photosynthesis, promote plant root development, and accelerate plant growth and reproduction. The standard of water-soluble fertilizer containing amino acids is NY1429-2010. Application characteristics: amino acid fertilizer is used in crops, which can obviously increase yield, improve quality, reduce pesticide residues and protect ecological environment. In addition, due to the continuous improvement of the production process of amino acid fertilizer, the source of raw materials is wide, and the production cost is getting lower and lower, which provides a guarantee for cheap acquisition of amino acid chelates. Therefore, amino acid fertilizer is playing a more and more important role in agricultural production. In terms of environmental protection, amino acid fertilizer can balance nutrition, provide fertilizer for green pollution-free and organic products, improve soil quality, improve the utilization rate of chemical fertilizer and reduce environmental pollution. As far as crops and farmers are concerned, the yield-increasing effect of amino acid fertilizer is very obvious, especially for cash crops, and the application of amino acid foliar fertilizer has obvious effect on improving quality (especially fruit trees). From the perspective of farmers' consumption consciousness, farmers, especially in cash crops and vegetable growing areas, are more and more aware of the development space of organic food and green food, so the market prospect of amino acid fertilizer will be wider and wider.
