Environmentally-friendly efficient microbial compound fertilizer and preparation method thereof

Abstract

The invention discloses an environmentally-friendly efficient microbial compound fertilizer and a preparation method thereof. The environmentally-friendly efficient microbial compound fertilizer is prepared from chicken manure, cow dung, dried pond sludge powder, ground phosphate rock, edible fungi residues, furfural residues, a microbial agent, wheat bran, bean cakes, urea, ammonium nitrate, potassium humate, wheat straws, charcoal powder and traditional Chinese medicine residues, wherein the microbial agent is prepared from bacillus licheniformis, bacillus subtilis, bacillus mucilaginosus, bacillus megatherium, pseudomonas, bacillus thuringiensis, bacillus amyloliquefaciens and nitrogen-fixing bacteria. The edible fungi residues and the furfural residues are smashed and mixed with water, the microbial agent is added for fermentation, the Chinese traditional medicine residues are added to perform fermentation, then the rest of the raw materials are added, and the microbial compound fertilizer can be obtained by performing full mixing, granulation and drying. The raw materials used for the microbial compound fertilizer are all natural fertilizers and contain rich mineral substances, the damage of a soil acid-base structure and a nutritional ingredient structure caused by inorganic fertilizer application is avoided, and the environmentally-friendly efficient microbial compound fertilizer is greener and more environmentally-friendly.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to an environmentally friendly and efficient microbial compound fertilizer and a preparation method thereof. Background technique [0002] In my country, due to the long-term use of chemical fertilizers for many years, the shortage of organic fertilizers and the imbalance of various nutrients have caused the ecological environment of farmland, soil physical and chemical properties and soil microbial flora to be damaged to varying degrees, which has affected the safety of agricultural products to a certain extent. . At present, crop pest control is mainly to use chemical agents and toxic pesticides to mix and stir, and apply them to the soil or crops. Long-term use of a large amount of pesticides and fertilizers will easily cause pesticide resistance of pests, soil compaction, and damage to water sources, soil and crops. Pollution is caused, and the quality of agricultural pro...

Problems solved by technology

[0003] Since the growth and development of crops requires a variety of nutrient elements, microbial fertilizers with a single strain and single function can no longer meet the needs of modern agricultural development. Modern microbial fertilizers cannot be composed of only a single strain, but tend to be compound microbial fertilizers.

Compound microbial fertilizer is an organic combination of inorganic nutrient elements, organic matter and microbial bacteria, which reflects the comprehensive effect of inorganic chemical fertilizers, organic fertilizers and microbial fertilizers, overcomes the shortcomings of traditional organic fertilizers, and overcomes the shortcomings caused by simple chemical fertilizers. Disadvantages such as degradation of soil physical and chemical properties and decline in the quality of agricultural products

[0004] my country has always advocated the rapid and sustainable development of agriculture, but due to various reasons, the utilization rate of my country's compound microbial fertilizers has been kept at a low level
