Medium and trace element nutritional synergist with abundant sulfur and zinc and application of medium and trace element nutritional synergist

Abstract

The invention relates to a medium and trace element nutritional synergist with abundant sulfur and zinc and application of the medium and trace element nutritional synergist. The medium and trace element nutritional synergist comprises 38%-75% of medium and trace element components, 0.5%-4% of dispersing agents, 0.5%-6% of wetting agents, 0.5%-5% of film-forming agents, 0.5%-5% of coalescing agent, 0.5%-5% of fillers, 19.5%-40% of water and 0.5%-2% of pigments. Various components are uniformly mixed with one another to obtain a product which is flow emulsion, and the coalescing agent is ethylalcohol or texanol ester alcohol. The application includes enveloping granular macro-element fertilizers and powdery fertilizers with the medium and trace element nutritional synergist for providing medium and trace element nutrition such as the sulfur and the zinc for the fertilizers; coating seeds with the medium and trace element nutritional synergist for improving the vitality of the seeds, increasing the germination rate of the seeds and improving the activity of seedlings; spraying the medium and trace element nutritional synergist on leaf surfaces for quickly providing the medium and trace element nutrition such as the sulfur and the zinc for crops; applying the medium and trace element nutritional synergist to drip irrigation and fertilization, allowing the medium and trace elementnutritional synergist and other macro-element fertilizers to be fed to positions near the root systems of the crops and further allowing the medium and trace element nutritional synergist to be absorbed by the root systems of the crops. The medium and trace element nutritional synergist and the application have the advantages that a medium and trace element nutritional layer can be quickly and efficiently formed on the surface of each fertilizer or the surface of each seed without drying, and the medium and trace element nutritional synergist is excellent in leaf surface spraying performanceand suspension fertilizer performance.

Description

technical field [0001] The invention relates to the manufacture of novel fertilizers and seed coating, in particular to the manufacture and application of a nutritional synergist rich in trace elements in sulfur and zinc. Background technique [0002] China is a large agricultural country. Various fertilizers, especially chemical fertilizers, have made an indelible contribution to my country's food security. The main fertilizers are urea, phosphorus fertilizer and potassium fertilizer, as well as various N:P:K formulations prepared from the above three raw materials. Compared with the compound fertilizer. The use of these fertilizers has played an important role in increasing farmers' production. However, in recent years, farmers have generally reported that no matter how much chemical fertilizers are used, the effect of increasing production is not obvious, that is, the output and the amount of chemical fertilizers used form an S curve. In addition, people also found that ...

Problems solved by technology

3. Magnesium participates in the conversion process of phosphoric acid, without magnesium, the output cannot be formed

3. Sulfur is not a component of chlorophyll, but it affects the synthesis of chlorophyll

2. Manganese deficiency inhibits protein synthesis, causing nitrate to accumulate in plants, making plants harmful

2. When molybdenum is deficient, molybdenum protein cannot be synthesized, resulting in the accumulation of nitrate in plants, making plant food harmful

3. Molybdenum deficiency affects nitrogen fixation by nitrogen-fixing bacteria

[0018] However, fertilizer companies encountered a problem in the process of producing fertilizers containing medium and trace elements: Among the 10 trace elements required by crops, except for sulfur, boron and silicon, other elements are metal elements, and these metal elements are only Only in the ionic state or chelated state or activated state can it be absorbed by crops

[0046] With the improvement of people's requirements for crop yield and quality, in addition to applying some trace element fertilizers to the soil, scientifically, some medium and trace element foliar fertilizers and drip fertilization will be combined with foliar spraying, especially for economic crops, such as fruit and vegetable crops. A large amount of foliar fertilizer will be used. Generally, some water-soluble inorganic salts such as zinc sulfate are used in large quantities to supplement the nutrition of medium and trace elements. This method is very costly, so it limits the scope of application. Only a single soil fertilization method is adopted, which affects the improvement of crop yield and quality
