Problems solved by technology

[0002] Over the years, in crop cultivation, the amount of chemical fertilizers has been increasing, and the amount of organic fertilizers has been decreasing, while the utilization rate of chemical fertilizers by crops is only about 30%, and about 70% of chemical fertilizers are deposited and fixed in the soil. Or it is lost in the rivers with the rain and is not absorbed and utilized by crops, which causes soil compaction, environmental pollution, eutrophication of rivers and groundwater is becoming more and more serious, soil organic matter content decreases, fertility decreases, and the living space of beneficial microorganisms in the soil becomes smaller , the number is reduced, the disease resistance, cold resistance, and drought resistance of crops are weakened, and the occurrence of diseases and insect pests is becoming more and more serious, resulting in a decline in crop quality and yield reduction

Abstract

The invention discloses a complex microorganism organic fertilizer and a preparation method thereof. The complex microorganism organic fertilizer is prepared by the following steps of: putting the following raw materials in proportion by weight into a Saccharomgces cerevasae liquid accounting for 0.5-0.8% of the weight of the raw materials, a Bacillus laterosporus liquid accounting for 0.1-0.5% of the weight of the raw materials and Bacillus megaterium liquid accounting for 0.1-0.5% of the weight of the raw materials for fermentation, wherein the raw materials comprise 1-50 parts of castor bean meal, 1-50 parts of cow or chicken dung, 1-20 parts of rice hull bran, 1-10 parts of bone meal, 1-80 parts of straws and 1-40 parts of rapeseed oil and cake in proportion by weight; and after the fermentation, adding 1-20 parts of urea, 0.5-10 parts of double superphosphate and 0.5-15 parts of potassium sulfate to prepare into the complex microorganism organic fertilizer, wherein the moisture content of the complex microorganism organic fertilizer is below 30 percent. The organic fertilizer can completely substitute a chemical fertilizer and can be used a base fertilizer or a additional fertilizer.
