Production method of compound microorganism fertilizer

Abstract

The invention discloses a production method of a compound microorganism fertilizer. The production method comprises steps as follows: an azotobacter chroococcum bacterial agent and a soil silicate bacterial agent in the weight ratio being 1: (0.5-1.5) are stirred and mixed in proportion; 2-8kg of flour and 10-40kg of clear water are taken and then stirred and mixed in the proportion being 1: (4-6), and a liquid culture medium is prepared; the stirred mixture is placed in the liquid culture medium and left to stand for 24 hours at the temperature of 10-30 DEG C, and the compound microorganism fertilizer is obtained. The source of soil nitrogen is increased; phosphorus and potassium which are difficult to dissolve are converted into a phosphorus and potassium compound which can be absorbed and used by crops, and the nutrition condition of the crops is improved. Microorganisms can generate a large amount of plant growth hormone in the breeding process to stimulate and adjust crop growth, accordingly, plants grow healthily and robustly, and absorption of nutritional elements is promoted; the disease resistance and drought resistance ability of the plants are enhanced, breeding of pathogenic microorganisms is inhibited, water absorption is increased, the use quantity of fertilizers is reduced, and the crop quality is improved.

Description

technical field [0001] The invention relates to microbial fertilizers, in particular to a production method of compound microbial fertilizers. Background technique [0002] China is a large agricultural country, and agriculture is the foundation of the national economy. The development of agriculture is not only of strategic significance to the economic development of our country, but also to the agricultural production and economic development of the world. At present, due to the increase in the use of pesticides and chemical fertilizers around the world, the dependence on pesticides and chemical fertilizers is increasing, resulting in insufficient use of organic fertilizers, imbalanced soil nutrient ratios; land compaction, soil quality decline; river and groundwater pollution, etc. series of questions. In order to avoid repeating the mistake of "pollution first, then destruction, then treatment" in developed countries, and to develop "sustainable agriculture", it is nece...
