Abstract

The invention relates to a microbial composite fertilizer and a preparation method thereof. The microbial composite fertilizer comprises: by weight, 5 to 15 parts of urea, 5 to 15 parts of monoammonium phosphate, 5 to 15 parts of potassium sulfate, 10 to 30 parts of weathered coal, 2 to 10 parts of a calcium-magnesium-phosphate fertilizer, 30 to 80 parts of organic fertilizer powder and 3 to 5 parts of composite bacteria. Compared with simple chemical fertilizers, the microbial composite fertilizer is more scientific and reasonable in composition and structure, has a higher level than a level of a traditional fertilizer in performance, improves a nutrient absorption rate of a crop from 30% to 65%, improves soil compaction and increases fertility of soil.

Description

technical field [0001] The invention relates to the field of microbial fertilizers, in particular to a microbial compound fertilizer and a preparation method thereof. Background technique [0002] The contribution of chemical fertilizers to solving the problem of food and clothing is universally recognized. Among the various elements of increasing grain production, the contribution rate of chemical fertilizers is 50%. Putting in one kilogram of fertilizer will increase the yield of grain by 10-15 kilograms. Modern agricultural production has developed to the point of relying on, or even relying on, chemical fertilizers. The input of fertilizer has accounted for 50% of the total input of agricultural production. [0003] However, chemical fertilizers can also damage the soil, causing deterioration of soil physical and chemical indicators, degradation of soil fertility, and damage to the foundation of human existence. It casts a heavy shadow on the road of sustainable devel...
