Biological organic fertilizer special for soybean and preparation method thereof

Abstract

The invention discloses a biological organic fertilizer special for soybean and a preparation method thereof. The biological organic fertilizer is prepared from the following raw materials in parts by weight by fermenting through a microbial agent: 15-24 parts of animal wastes, 20-26 parts of straws, 7-12 parts of wheat bran, 6-10 parts of fungi culture fungi residues, 2-6 parts of saw dust, 1-3 parts of maize meal, 1-3 parts of bean pulp and 10-19 parts of tap water, wherein the weight ratio of the microbial agent is composed of EM bacteria, saccharomycetes and nitrogen-fixing bacteria at a ratio of 3:1:1, and the inoculation amount of the microbial agent accounts for 0.1% of the weight of the raw materials. The preparation method disclosed by the invention can not only reduce the expense of treating the animal wastes, but also achieve the effect of waste utilization, solves the problem of pollution of the animal wastes on the environment, also solves the problem that the straws, the wheat bran and the fungi culture fungi residues are difficult to treat, meets the requirements of ecological circular agriculture and is low in cost and easy to operate.

Description

technical field

[0001] The invention relates to the technical field of agriculture, in particular to a special bio-organic fertilizer for soybeans and a preparation method thereof. Background technique

[0002] Soybean is an important food crop and economic crop. Its output and planting area are second only to rice, wheat, and corn, ranking first in the world. Soybean plays an important role in the national economy and people's livelihood. In recent years, with the rapid development of the livestock and poultry breeding industry, the demand for soybean meal in the corresponding feed industry is also in a state of short supply. Therefore, it is the direction of people's efforts to make effective use of land resources and improve the yield and quality of soybeans. In addition, animal manure from animal husbandry becomes animal husbandry waste. If it is specially treated, it will take a lot of manpower and material resources. The treatment of crop straw and fungus breeding res...
