Chinaure-containing high-efficiency slow-release compound fertilizer

Abstract

The invention relates to the field of compound fertilizers, particularly a chinaure-containing high-efficiency slow-release compound fertilizer. The fertilizer is prepared from the following raw materials in parts by weight: 10-15 parts of 1250-2000-mesh kieselguhr, 12-15 parts of calcium superphosphate, 20-22 parts of urea, 12-14 parts of plant ash, 15-18 parts of sugar mill lime sludge, 8-10 parts of rotten vegetable leaf, 4-6 parts of glycerophosphate sodium, 5-8 parts of xylanase, 20-22 parts of oil tea cake powder, 28-30 parts of poultry manure, 4-6 parts of sodium isoascorbate, 10-12 parts of glycidol ether epoxy resin, 3-5 parts of butyl glycidyl ether, 1-2 parts of polyethyleneglycol, 1-2 parts of ethylenediamine, 5-7 parts of pine needle powder, 2-4 parts of chinaure, 4-5 parts of borax, 2-3 parts of sodium tripolyphosphate, 1-3 parts of potassium permanganate, 2-4 parts of zinc gluconate, 6-8 parts of table vinegar and 4-5 parts of assistant. The compound fertilizer has multiple nutrients; the kieselguhr and coating agent are utilized to implement dual slow-release coatings; and the coating agent contains the chinaure, and can prevent the insects and ants from biting. The fertilizer has the advantages of low tendency to nutrient loss, long fertilizer efficiency, no toxicity or harm to soil and favorable crop root environment, has the functions of sterilization and corrosion resistance, and enhances the yield and quality.

Description

technical field [0001] The invention relates to the field of compound fertilizers, in particular to a high-efficiency slow-release compound fertilizer containing pepper grass. 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 fertilizers. How...

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
