Abstract

Provided is a water-soluble fertilizer, comprising chelated iron, boric acid, calcium dihydrogen phosphate, manganese sulfate, zinc sulfate and copper sulfate. After the fertilizer is applied, a stable soil aggregate granule structure can be formed, the gas permeability of soil and the physical-chemical environment of various nutrient elements in soil are improved, and the absorptive capacity of the soil granule surface and the adduct action of various nutrient substances are increased. A nutrient protective zone can be rapidly formed around plant roots, the diffusion speed and migration distance of nutrients such as nitrogen, phosphorus and potassium in soil are increased, and the absorption and utilization of moisture and nutrients by roots are promoted.

Description

[Name of invention established by ISA in accordance with Rule 37.2] A water-soluble fertilizer

Technical field

This invention relates to fertilizers and, more particularly, to a novel water soluble fertilizer.

Background technique

With the advancement of science and the development of society, the population of the earth is constantly increasing. In order to solve the increasing demand for food, the status of agricultural science and technology is becoming more and more important. In the development of agricultural science and technology, fertilizer has played a vital role. However, for many years, only 20% to 30% of the chemical fertilizer applied to the soil has been absorbed and utilized by the seasonal crops. The remaining chemical fertilizers have been fixed by the soil, forming a large amount of phosphate and nitrate deposits, which destroy the agglomerate structure of the soil. The soil is compacted, the soil fertility is reduced, and the cultivation is deteriorated. Therefore, it is urgent to develop a new type of water-soluble fertilizer with high absorption and utilization.

Summary of the invention

The technical problem to be solved by the invention is that the absorption rate of the new water-soluble chemical fertilizer against the prior art is low, and the residual chemical fertilizer is fixed by the soil, forming a large amount of phosphate and nitrate deposition residue, destroying the agglomerate structure of the soil and causing soil. A new type of water-soluble fertilizer is provided for defects such as compaction, soil fertility, and poor cultivation.

The technical solution adopted by the present invention to solve the technical problem is: constructing a novel water-soluble chemical fertilizer, the composition and ratio thereof are: 20 to 45 parts by weight of urea, 20 to 79 parts by weight of a phosphoric acid compound, and 20.5 to 48 weights. Parts of sulfate, 0.1 to 1.5 parts by weight of borax, bismuth iron 20 to 40 parts of boric acid, 2 to 5 parts of calcium dihydrogen phosphate, 2 to 5 parts of manganese sulfate, 1 to 3 parts of zinc sulfate, 0.1 to 0.5 parts of sulfuric acid Copper, 0.05 to 0.1 parts. 0.1 to 2 parts by weight of ammonium heptamolybdate and 0.5 to 15 parts by weight of polyacrylized Compound.

The novel water-soluble fertilizer of the present invention has the following beneficial effects: by constructing a water-soluble fertilizer composed of a large amount of elements of a full-speed powder-soluble fertilizer, the application of the novel water-soluble fertilizer can form a stable soil agglomerated particle structure to improve soil permeability. Improve the chemical and physical environment of various nutrients in the soil, increase the adsorption capacity of the soil surface, increase the cooperation of various nutrients, and rapidly form a nutrient protection zone at the root of the plant after application, increasing nitrogen and phosphorus. The diffusion rate and migration distance of potassium and other nutrients in the soil promote the absorption and utilization of water and nutrients by roots. It can improve the water holding capacity and fertilizer retention capacity of the soil, improve the water content of the soil, inhibit the evaporation and preservation, improve the soil's substitution and absorption capacity, stimulate the growth of effective microorganisms in the soil, and improve the micro-ecological environment of the soil. It can promote the synthesis of nutrients such as amino acids, soluble sugars and vitamins, and reduce the content of harmful substances such as nitrates and heavy metals.

detailed description

Example one

Constructing a novel water-soluble fertilizer with a composition and ratio of 20 parts by weight of urea, 20 parts by weight of a phosphoric acid compound, 20 parts by weight of a sulfate, 0.1 part by weight of borax, 20 parts by weight of boric acid, 2 Part of calcium dihydrogen phosphate, 2 parts of manganese sulfate, 1 part of zinc sulfate, 0.1 part of copper sulfate, 0.1 part by weight of ammonium heptamolybdate and 0.5 parts by weight of a polypropylene compound.

The new water-soluble fertilizer does not contain any harmful substances to the soil, but reduces the damage caused by the soil disease to the plant. The viscous polymer formed by the dissolution of the new water-soluble fertilizer has a strong adsorption effect, which greatly reduces The loss of nutrients prolongs the fertilizer efficiency and increases the utilization rate of fertilizers, so that the fertilizer efficiency can last for more than 180 days. Finally decomposed into carbon dioxide and Water, no residue, eco-friendly. Improve the soil structure, so that the soil forms agglomerate structure, soil loose, breathable, water retention, fertilizer. It can effectively decompose N.P.K and other substances fixed by soil, and convert it into nutrients that can be directly absorbed and utilized by crops, and improve the utilization rate of fertilizers.
