Organic-inorganic compounded sustained-release fertilizer capable of enhancing soil activity

Abstract

The invention relates to the field of composite fertilizers, and concretely relates to an organic-inorganic compounded sustained-release fertilizer capable of enhancing soil activity. The fertilizer is prepared from the following raw materials in parts by weight: 10-15 parts of 1250-2000 mesh diatomite, 6-8 parts of old Chinese cabbage leaves, 18-20 parts of urea, 8-10 parts of heavy calcium, 12-15 parts of potassium sulfate, 1-3 parts of acorn powder, 1-3 parts of waste tobacco leaves, 4-6 parts of celery roots and leaves, 2-4 parts of cabbage stumps and leaves, 1-2 parts of manganese sulfate, 3-5 parts of borax, 2-4 parts of ferric citrate, 1-2 parts of sodium tetraborate, 18-20 parts of decomposed barnyard manure, 8-10 parts of natural calcium bentonite, 6-8 parts of olea europaea oil sediment, 6-9 parts of sodium carbonate, 5-8 parts of potassium chloride, 15-18 parts of seaweed gel and 4-5 parts of an auxiliary agent. According to the composite fertilizer, wastes in life and production are fully utilized and are subjected to fermentation processing, so that nutrients are relatively easy to absorb and utilize by crops; dual cladding on nutrients is formed by utilizing diatomite and a sustained-release coating agent in the technology, so that nutrients are not easy to lose, and the fertility is durable and efficient; the sustained-release agent is completely degradable without destroying soil environment; and crops grow vigorously, is strong in disease resistance and obvious production-increasing output-increasing effects.

Description

technical field [0001] The invention relates to the field of compound fertilizers, in particular to an organic-inorganic compound slow-release fertilizer that enhances soil activity. 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 fertilizer...

AI Technical Summary

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
