Natural disease-resistant high-yield slow-release compound fertilizer

Abstract

The invention relates to the field of compound fertilizers, and particularly relates to a natural disease-resistant high-yield slow-release compound fertilizer which is prepared from the following raw materials in parts by weight: 10-15 parts of 1250-2000-mesh kieselguhr, 18-23 parts of monoammonium phosphate, 10-12 parts of potassium chloride, 15-18 parts of ammonium chloride, 3-5 parts of walnut green seedcase, 6-8 parts of boron-magnesium fertilizer, 2-5 parts of raw gypsum powder, 3-5 parts of ferrocene, 6-8 parts of Alexandria laurel leaf, 10-12 parts of horse manure, 3-5 parts of safflower Lycoris radiata aqueous extract, 6-8 parts of wood dust, 3-6 parts of poplar peel, 7-9 parts of calcium phosphate, 2-4 parts of tonka powder, 1-3 parts of sweet orange peel ultramicropowder, 1-3 parts of water-soluble lanolin, 5-7 parts of polyvinylpyrrolidone, 10-12 parts of gelatin, 2-3 parts of thiocarbamide and 4-5 parts of assistant. The compound fertilizer fully utilizes common cheap organic matters in daily production and life, lowers the production cost, improves the soil environment, and utilizes the kieselguhr and modified gelatin slow-release coating agent to form dual coatings on the nutrients, so that the fertilizer efficiency is more endurable, thereby reducing the inefficient loss of nutrients, effectively enhancing the yield and quality of the crops and enhancing the disease-resistant and antimicrobial capacities of the crops.

Description

technical field [0001] The invention relates to the field of compound fertilizers, in particular to a natural disease-preventing high-yield slow-release compound fertilizer. 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.

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
