Efficient slow release composite fertilizer for wheat

Abstract

The invention discloses an efficient slow release composite fertilizer for wheat. The fertilizer comprises the following raw materials in parts by weight: 20-30 parts of ammonium chloride, 15-20 parts of potassium sulphate, 20-30 parts of mono-ammonium phosphate, 15-20 parts of a calcium-magnesium-phosphorus fertilizer, 5-19 parts of a white phosphorus fertilizer, 4-10 parts of pregelatinized starch, 2-4 parts of a full gemma microbial preparation, 20-30 parts of feather meal, 10-20 parts of gourmet powder residues, 20-40 parts of starch residues, 20-30 parts of sugar residues, 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, 5-8 parts of kaolin, 15-20 parts of attapulgite clay powder, 10-14 parts of weathered coal, 20-25 parts of zeolite powder, and 5-10 parts of calcium silicate. According to the invention, the efficient slow release composite fertilizer can improve soil, and is comprehensive in nutrition, and high in slow release effect.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a high-efficiency slow-release 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 destroy the structure of soil aggregates, thereby affecting the growth of wheat, and the promotion effect on wheat growth is not obvious. Organic fertilizers are processed from biomass, animal and plant waste, and p...

Problems solved by technology

However, long-term use will destroy the structure of soil aggregates, thereby affecting the growth of wheat, and the promotion effect on wheat growth is not obvious. Organic fertilizers are processed from biomass, animal and plant waste, and plant residues to eliminate toxic and harmful substances. , rich in a large number of beneficial substances, not only can provide comprehensive nutrition for crops, but also has a long fertilizer effect, can increase and renew soil organic matter, promote microbial reproduction, improve soil physical and chemical properties and biological activity, is the main nutrient for green food production, but the current fertilizer effect Short, low utilization rate, how to prepare a fertilizer that can improve the soil, comprehensive nutrition and good slow-release effect has become a technical problem that needs to be solved at present
