High-efficiency slow-release compound fertilizer containing grape skin

Abstract

The invention relates to the compound fertilizer field, and more specifically relates to a high efficiency slow release compound fertilizer containing grape skin, and comprises the following raw materials by weight: 10-15 parts of 1250-2000 meshes diatomite, 25-30 parts of biogas slurry, 2-4 parts of zinc sulfate, 20-25 parts of monoammonium phosphate, 1-2 parts of ammonium molybdate, 15-18 parts of urea, 16-18 parts of potassium chloride, 4-5 parts of dry grape, 2-5 parts of animal crushed bone meal, 2-4 parts of zinc gluconate, 6-8 parts of edible vinegar, 10-12 parts of water hyacinth fresh slurry, 30-35 parts of decomposed rapeseed cake, 10-12 parts of non-ionic polyurethane dispersion liquid, 1-2 parts of polyethylene glycol, 18-20 parts of brewer's grain and 4-5 parts of auxiliary agent. The composite fertilizer has the advantages that production cost is low, raw materials such as waste grape skin can be used, technology is simple, nutrient is rich, duration time of the fertilizer efficiency is long, nontoxicity and innocuousness can be generated to soil, certain sterilization anticorrosion effect is provided, crop insect disease condition can be mitigated, and increasing yield and income effect is obvious.

Description

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