Abstract

The invention relates to the field of compound fertilizer, and in particular to a coating slow-released compound fertilizer for improving soil and promoting growth. The fertilizer is prepared from the following raw materials by weight: 10-15 parts of diatomite of 1250-2000 mesh, 15-18 parts of composted livestock and poultry manure, 2-4 parts of zinc sulfate, 12-15 parts of ammonium nitrate, 6-8 parts of potassium humate, 5-8 parts of calcium sulfate, 3-5 parts of magnesium sulfate, 2-3 parts of ferrous sulfate, 6-8 parts of a Tripterygium wilfordii aqueous extract, 2-5 parts of beer yeast, 4-5 parts of southern magnolia fallen leaves, 10-12 parts of wheat bran, 5-7 parts of Astragalus adsurgens all grass, 1-2 parts of snail shell powder, 1-3 parts of betaine, 4-6 parts of pigeon manure, 20-22 parts of urea, 14-16 parts of zein, 4-5 parts of polyvinyl butyral, a proper amount of 90% ethanol water solution, 2-3 parts of oleic acid, 1-3 parts of glycerol monostearate and 4-5 parts of an auxiliary. The compound fertilizer provided by the invention has extensive raw material sources and comprehensive and rich nutrients, utilizes diatomite and modified zein slow-released coating agent to form double coating on the nutrients in the production process, so as to realize lasting fertilizer efficiency; and the compound fertilizer contains a variety of natural soil improvers, improves soil vitality, and can continuously improve the yield and quality of crops.

Description

technical field [0001] The invention relates to the field of compound fertilizers, in particular to a slow-release compound fertilizer for improving soil growth and promoting coating. Background technique [0002] In modern agricultural production, compound fertilizer can be seen everywhere. It has the advantages of high nutrient content, less auxiliary components, high fertilizer utilization rate, and convenient storage and application. It plays an important role in promoting high and stable crop yields. Slow-release compound fertilizer is an important category of compound fertilizers, and it is also the focus of research on the development of my country's chemical fertilizer industry. Its slow-release principle is to coat a thin layer of hydrophobic substances on the surface of fertilizer particles, so that the internal nutrients are slowly released to the In the soil, nutrients are continuously supplied to crops, which effectively improves the utilization rate of fertilize...
