Efficient sustained-release compound fertilizer containing waste mushroom stalks

Abstract

The invention relates to the field of compound fertilizers and particularly relates to an efficient sustained-release compound fertilizer containing waste mushroom stalks. The fertilizer is prepared from the following raw materials in parts by weight: 10-15 parts of diatomite of 1250-2000 meshes, 6-8 parts of peanut shell fine powder, 15-18 parts of waste mushroom stalks, 4-5 parts of angelica keiskei leaves, 12-13 parts of purple potato slag, 2-4 parts of D-sodium erythorbate, 5-6 parts of galanga leaves, 4-5 parts of yeast powder, 1-3 parts of zinc sulfate, 10-12 parts of calcium superphosphate, 20-23 parts of monoammonium phosphate, 22-28 parts of urea, 3-5 parts of ferrous sulfate, 10-14 parts of xylitol slag, 1-2 parts of eugenol powder, 12-15 parts of glycol chitosan, 0.1-0.3 part of glutaraldehyde, 6-8 parts of polyvinyl alcohol, 2-4 parts of cellulose ether and 4-5 parts of auxiliaries. According to the compound fertilizer disclosed by the invention, waste materials in daily lives are fully utilized to ensure more sufficient and varied nutrients on the basis of reducing the production cost, and the diatomite and a sustained-release coating agent are used for forming double coating on the nutrients to ensure more durable fertilizer efficiency so as to obviously improve the yield and quality of crops, so that the compound is a novel green and efficient compound fertilizer.

Description

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

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
