Problems solved by technology

However, the existing slow-release compound fertilizers still have certain shortcomings, mainly in that the nutrient ratio is relatively fixed, and it is difficult to meet the different needs of various soils and various crops; the slow-release effect is not satisfactory, and does not match the growth needs of crops , thereby reducing fertilizer efficiency, affecting crop growth, resulting in reduced production and income

Abstract

The invention relates to the field of composite fertilizers, in particular to a slow-release composite fertilizer capable of preventing crop premature senility and pest and disease damage. The fertilizer is prepared from the following raw materials in parts by weight: 10-15 parts of 1,250-2,000-mesh diatomite, 20-22 parts of diammonium phosphate, 10-12 parts of calcium magnesium phosphate fertilizer, 6-8 parts of borax, 10-12 parts of leftovers in a grape wine plant, 2-3 parts of litsea cubeba leaves, 12-15 parts of germinated brown rice, 12-15 parts of potassium magnesium sulfate, 2-4 parts of ferrous sulfate, 15-18 parts of fermented manure, 4-6 parts of potassium silicate, 1-3 parts of bacillus megatherium, 10-12 parts of yellow bean residues, 13-14 parts of waste mushroom culture materials, 1-3 parts of marigold root water extract, 0.1-0.2 part of artemisia vulgaris oil, 12-15 parts of gelatin, 2-3 parts of animal grease, 1-2 parts of Tween 80, 3-5 parts of magnesium stearate and 4-5 parts of an assistant. The composite fertilizer is rich in raw material type and rich in nutrition; nutrients are double coated with the diatomite and a slow-release coating agent, so that the fertilizer efficiency is relatively lasting; moreover, the composite fertilizer has environment-friendly and safe pest-proof, corrosion-proof and bactericidal effects, so that the soil activity is good, the crop premature senility is hardly caused, the crop yield can be effectively increased, and the crop quality can be effectively improved.

Description

technical field [0001] The invention relates to the field of compound fertilizers, in particular to a slow-release compound fertilizer for preventing premature aging of crops and preventing pests and diseases. 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 uti...
