Green organic agricultural fertilizer and preparation method thereof

Abstract

The present invention discloses one new kind of green organic agricultural fertilizer and its preparation process. The material for the green organic agricultural fertilizer consists of coal gangue powder 20-30 wt%, stalk powder 10 -20 wt%, urea 5-10 wt%, calcium superphosphate 20-30 wt%, monoammonium phosphate 5-10 wt%, potassium sulfate 5-10 wt%, bentonite 5-10 wt%, biofertilizer fermenting agent 5-8 wt%, and trace elements 2 wt%. The green organic agricultural fertilizer can strengthen plant resistance, reduce pesticide using amount to protect ecotope, raise yield and quality of agricultural product, prevent soil hardening and pollution and optimize plant growth conditions.

Description

technical field [0001] The invention relates to a fertilizer, and relates to a method for preparing an organic fertilizer by using biochemical technology, specifically, using industrial production waste coal gangue and agricultural production waste straw as basic raw materials, adopting modern biochemical technology and advanced production technology Refined into a new type of green organic agricultural fertilizer. Background technique [0002] In recent years, with the development of agricultural production, farmers have obtained high grain yields by using chemical fertilizers, and used highly toxic pesticides to prevent the damage of crops from pests and diseases. However, the above-mentioned chemical fertilizers and highly toxic pesticides have also brought potential hazards to agriculture, and as the hazards spread and develop, they directly endanger human health. For example, agricultural products (grain, fruit, vegetables) produced with highly ...

Problems solved by technology

However, the above-mentioned chemical fertilizers and highly toxic pesticides have also brought potential hazards to agriculture. As the hazards spread and develop, they directly endanger human health.

For example, agricultural products (grain, fruit, vegetables) produced with highly toxic pesticides will inevitably carry pesticide residues; long-term use of chemical fertilizers will cause soil compaction in rural farmland soil, destroy the soil aggregate structure, and affect the ecological balance of soil microorganisms. This will lead to a sharp drop in soil fertility, which will bring hidden dangers of reduced production to future agricultural production, and will also cause a serious decline in the quality of agricultural products produced. In recent years, the Ministry of Agriculture has realized this and requires the use of organic fertilizers in the soil to improve this state and protect the soil. ecological environment and human health

[0003] At present, many fertilizer manufacturers are developing new fertilizers, but they are far from meeting the demand. Therefore, the development of new green organic agricultural fertilizers is also a hot spot in the industry.
