High-efficiency biological organic fertilizer and preparation method

Abstract

The invention relates to a high-efficiency biological organic fertilizer and a preparation method, belonging to the field of fertilizers and preparation. The preparation method comprises the following steps of: uniformly mixing 40-70 parts of livestock manure, 20-30 parts of rice hull, 10-20 parts of straw powder and 10-20 parts of compound microbial starter culture, then adding water into the mixture, wherein water is controlled to account for 45-55%, and placing the mixture in a fermentation tank for sealing fermentation; when a fermentation temperature reaches 58-60 DEG C, turning over the material, feeding oxygen into the material for 7-15 days, thereby finishing the fermentation step, and finally carrying out temperature reduction decomposition on the mateiral, drying, crushing and pelleting, thereby obtaining the high-efficiency biological organic fertilizer. The compound microbial starter culture of the invention has rich nutrients and can meet the requirements of the crops for nutrients in the whole growth period; and as microbes generate lots of metabolites with the special effect, the high-efficiency biological organic fertilizer has the advantages of being capable of obviously inhibiting harmful microbes, increasing the ground temperature and the disease resistance of the crops, stimulating and adjusting the rapid growth and development of crops, partially or completely replacing a chemical fertilizer, reducing the input of the chemical fertilizer in green food, improving the ecological environment of soil, leading the soil to become loose, solving the problem of soil hardening and increasing soil productivity.

Description

technical field [0001] The invention belongs to fertilizer and its preparation, in particular to a high-efficiency bio-organic fertilizer and its preparation method. Background technique [0002] With the enhancement of people's awareness of health care, green and environmentally friendly food has become the first choice of people. However, the current agricultural planting in my country still relies on chemical fertilizers to increase production and income. The extensive use of chemical fertilizers has caused soil ecological environment to deteriorate, soil compaction, and buffer capacity. The ability to resist natural disasters is weakened, soil fertility decreases, and the microbial community in the soil changes, which eventually induces the incidence of various crop diseases, resulting in negative effects of reduced grain production, high input and low output. More importantly, as chemical fertilizers are continuously and massively input into farmland, harmful chemicals a...

[0002] With the enhancement of people's awareness of health care, green and environmentally friendly food has become the first choice of people. However, the current agricultural planting in my country still relies on chemical fertilizers to increase production and income. The extensive use of chemical fertilizers has caused soil ecological environment to deteriorate, soil compaction, and buffer capacity. The ability to resist natural disasters is weakened, soil fertility decreases, and the microbial community in the soil changes, which eventually induces the incidence of various crop diseases, resulting in negative effects of reduced grain production, high input and low output

More importantly, as chemical fertilizers are continuously and massively input into farmland, harmful chemicals are enriched in organisms through soil and water bodies, and enter crops and livestock through the food chain, leading to food pollution and ultimately harming the human body healthy
