Composite fertilizer for wheat

Abstract

The invention discloses a composite fertilizer for wheat. The fertilizer comprises the following raw materials in parts by weight: 20-30 parts of urea, 20-30 parts of potassium chloride, 20-30 parts of monoammonium phosphate, 15-20 parts of ordinary calcium superphosphate, 2-4 parts of full gemma microorganism microbial inoculum, 20-30 parts of feather meal, 10-20 parts of gourmet powder residue, 20-40 parts of starch residue, 20-30 parts of sugar residue, 4-10 parts of pregelatinized starch, 2-5 parts of tung oil, 5-10 parts of disproportionated rosin, 5-8 parts of lignosulfonate, 2-5 parts of polyvinyl alcohol, 4-8 parts of carboxymethyl cellulose, 20-30 parts of activated carbon, 30-40 parts of organic carbon, 15-20 parts of borax, 15-20 parts of attapulgite clay powder, 10-14 parts of weathered coal, 5-10 parts of calcium bentonite and 20-25 parts of zeolite powder. According to the invention, the composite fertilizer for the wheat is environment-friendly, can improve soil, is good in slow release and is long in fertilizer application period.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a compound fertilizer for wheat. Background technique [0002] Chemical fertilizers and pesticides play a very important role in agricultural production. With the improvement of people's living standards and health awareness, people attach great importance to the safety of agricultural products. The demand for pollution-free and green food is increasing year by year. The current wheat planting uses There are many types of fertilizers, and N, P, and K compound fertilizers are mainly used. They are mainly composed of three inorganic elements, N, P, and K, and can meet the growth needs of wheat in a short time. However, long-term use will damage the soil aggregate structure, which will easily cause soil compaction and soil hardening, thereby affecting the growth of wheat, and the promotion effect on wheat growth is not obvious. Organic fertilizers are processed by biomass, anima...

Problems solved by technology

However, long-term use will damage the soil aggregate structure, which will easily cause soil compaction and soil hardening, thereby affecting the growth of wheat, and the promotion effect on wheat growth is not obvious. Organic fertilizers are processed by biomass, animal and plant waste, and plant residues. It eliminates the toxic and harmful substances in it, and is rich in a large number of beneficial substances. It can not only provide comprehensive nutrition for crops, but also has a long fertilizer effect. It can increase and renew soil organic matter, promote microbial reproduction, improve soil physical and chemical properties and biological activity, and is green. Key Nutrients for Food Production

However, the existing organic fertilizers have short fertilizer effects. How to prepare a green, environmentally friendly, soil-improving, slow-release, and long-lasting fertilizer has become a technical problem that needs to be solved at present.
