Microbial organic fertilizer and preparation method thereof

Abstract

The invention discloses a microbial organic fertilizer and a preparation method thereof and belongs to the technical field of fertilizers. The problems that the existing fertilizer is low in utilization rate and the land is easily hardened are solved. The microbial organic fertilizer is a fermentation product with the moisture content of 15-20wt% which is obtained by performing bacteria liquid inoculation fermentation on the following raw materials, wherein the inoculated bacteria liquid comprises the following components in percentage by weight: 45 percent of brewer yeast, 35 percent of bacillus subtilis, 13 percent of lactobacillus fermenti and 7 percent of EM bacteria; the raw materials comprise the following component in percentage by weight: 48 percent of human and animal excreta, 38 percent of crop straw, 12 percent of banana skin and 2 percent of traditional Chinese medicine compound; the inoculation amount of the fermentation inoculation bacteria liquid is 1 weight percent; and the traditional Chinese medicine compound comprises the following components in parts by weight: 3 parts of manyflower solomonseal rhizome, 6 parts of Chinese yam, 3 parts of Codonopsis pilosula, 3 parts of antifebrile dichroa, 8 parts of celastrus angulatus, 3 parts of areca catechu and 3 parts of andrographis paniculata. The organic fertilizer adopts the purely biological raw materials, is good in fertilizer efficiency and can be used for improving the soil structure, the environmental pollution is not generated, and the preparation method is simple.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a microbial organic fertilizer and a preparation method thereof. Background technique [0002] As the world's population continues to increase, the demand for food is also increasing, and the status of agricultural technology development is becoming more and more important. In the development of agricultural science and technology, chemical fertilizer plays a vital role. However, only 20% to 30% of the chemical fertilizers applied to the soil are absorbed and utilized by the crops of the current season, and the rest of the chemical fertilizers are fixed by the soil, forming a large amount of phosphate and nitrate deposition residues, causing waste of fertilizers and destroying the soil. Aggregate structure causes soil compaction, soil fertility decline, and arable performance become poor. Therefore, it is necessary to develop organic fertilizers to solve this problem. [00...

Problems solved by technology

However, only 20% to 30% of the chemical fertilizers applied to the soil are absorbed and utilized by the crops of the current season, and the rest of the chemical fertilizers are fixed by the soil, forming a large amount of phosphate and nitrate deposition residues, causing waste of fertilizers and destroying the soil. Aggregate structure, causing soil compaction, soil fertility decline, and poor cultivability. Therefore, it is necessary to develop organic fertilizers to solve this problem

[0003] Domestic waste (such as feces) or agricultural fertilizer (straw) is generally treated as garbage, which wastes manpower, material resources and land; it also pollutes the environment. If these wastes can be recycled, the production cost of fertilizers can be greatly reduced and waste For the treasure, benefit the country and the people

[0004] Organic fertilizers need to be fermented to achieve better results. If the fermentation is not complete, secondary fermentation will occur after fertilization, resulting in seedling burning. In the past, composting was generally used for fermentation, using the composting raw materials. Fermentation by microorganisms, the fermentation period is longer, the fermentation is not complete, and better fertilizer efficiency cannot be achieved, and it may also cause seedling burning
