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, and concretely relates to a long-acting sustained-release composite fertilizer rich in organic materials. The fertilizer is prepared from the following raw materials in parts by weight: 10-15 parts of 1250-2000 mesh diatomite, 12-15 parts of ammonium humate, 8-10 parts of triple superphosphate, 5-6 parts of pumace, 6-8 parts of bean dregs, 4-5 parts of grass meal, 5-7 parts of lees vinegar, 1-2 parts of white sugar, 0.5-1 part of xylose, 18-20 parts of urea, 5-6 parts of borax, 8-10 parts of sodium carboxymethylcellulose, 6-8 parts of redispersible latex powder, 2-3 parts of ammonium ferric citrate, 8-10 parts of ammonium dihydrogen phosphate, 0.1-0.2 part of calcium stearate and 4-5 parts of an auxiliary agent. The raw materials of the composite fertilizer are rich in multiple organic materials, so that the soil activity is effectively improved, and the adverse influence of long-term fertilization on soil is improved; dual cladding on nutrient is formed by utilizing diatomite and a sustained-release coating agent in the production technology, so that nutrient is not easy to loss, the utilization rate is greatly improved; and release of nutrient is long-acting and efficient, and sufficient nutrient and balanced soil environment help to improve both crop output and quality, and the plantation benefit is increased.

Description

technical field [0001] The invention relates to the field of compound fertilizers, in particular to a long-acting slow-release compound fertilizer rich in organic matter. 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. However,...
