Biological compound fertilizer

Abstract

The invention discloses a biological compound fertilizer. The biological compound fertilizer is prepared from, by mass, 3-10 parts of composite microbial inoculants, 3-5 parts of nitrogen-fixing bacteria, 3-5 parts of phosphobacteria, 3-5 parts of potassium-dissolving bacteria, 5-15 parts of humic acid, 10-20 parts of borax, 4-6 parts of chitin, 1-3 parts of polypeptide, 5-15 parts of seaweed fertilizer, 8-10 parts of zeolite powder and 1-3 parts of synergist. By adding seaweed fertilizer and multiple microbial inoculants into the fertilizer, the capability of crops for absorbing nutritional ingredients is effectively improved, the fertilizer waste is reduced, the damage of chemical fertilizer to soil is reduced, nutrient balance is achieved, and nutrients needed by crop growth are provided; the fertilizer is scientific and reasonable in formula, balanced in nutrition and capable of providing nutrients needed by crop growth, improving the quality of crops and increasing the economic benefit of crops.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a biological compound fertilizer. Background technique [0002] With the gradual increase in the utilization rate of domestic fertilizers, the requirements for fertilizers are also constantly increasing. At present, a large amount of chemical fertilizers are used, which seriously leads to the increase of harmful substances in crops, and the microbial flora has been damaged to varying degrees, resulting in poor quality. Insufficient nutrition, especially the soil is easy to compact, the drought resistance effect is poor, and the water retention performance becomes poor, which seriously affects the normal growth of crops, thereby affecting the poor economic benefits of agriculture. At present, some provinces have applied potassium bacterial fertilizers on a large scale, and achieved significant yield-increasing effects. This is an important development approach to solve the pot...

[0002] With the gradual increase in the utilization rate of domestic fertilizers, the requirements for fertilizers are also constantly increasing. At present, a large amount of chemical fertilizers are used, which seriously leads to the increase of harmful substances in crops, and the microbial flora has been damaged to varying degrees, resulting in poor quality. Insufficient nutrition, especially the soil is easy to harden, the drought resistance effect is poor, and the water retention performance becomes poor, which seriously affects the normal growth of crops, thus affecting the poor economic benefits of agriculture

At present, some provinces have applied potassium bacterial fertilizers on a large scale, and achieved significant yield-increasing effects. This is an important development approach to solve the potassium deficiency in agriculture, but it also has limitations. It cannot solve the problem that agriculture must provide nitrogen and phosphorus fertilizers through the application of chemical fertilizers.
