Preparation method of carbon-based biological bacterial fertilizer

Abstract

The invention discloses a preparation method of carbon-based biological bacterial fertilizer. The fertilizer is prepared from, by weight, 20 parts of sheep manure organic fertilizer, 10 parts of biomass charcoal, 15 parts of potassium fulvic acid, 10 parts of bacillus subtilis culture substances, 10 parts of aspergillus awamori culture substances, 10 parts of bentonite, 8 parts of nitrogen-phosphorus-potassium, 5 parts of polyglutamic acid, 3 parts of potassium bacteria agent and the balance water. The preparation method comprises the following steps that S1, by weight, potassium fulvic acid,bacillus subtilis culture substances, aspergillus awamori culture substances, nitrogen-phosphorus-potassium, bentonite and water are added into a stirrer, stirring and mixing are conducted for 5 min at the rotation speed of 60 r / min, and a mixture A is prepared; the sheep manure organic fertilizer and biomass charcoal are used as a matrix and added into the mixture A for secondary fermentation. The preparation method is reasonable in design, the preparation technology is simple, the preparation cost is low, the survival rate and propagation speed of microorganisms are increased, a substrate required by survival of the microorganisms is improved and optimized, and the method is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of biological bacterial fertilizer, in particular to a preparation method of carbon-based biological bacterial fertilizer. Background technique [0002] Due to the excessive use of inorganic fertilizers, the soil quality in many areas of my country is generally poor, especially in the low carbon-nitrogen ratio of the soil, which leads to the destruction of the soil microbial system, the continuous reduction of beneficial microorganisms, and seriously affects the growth and development of the root system. In order to improve soil quality and increase the number of beneficial microorganisms in the soil, in recent years, production has begun to pay attention to the application of microbial fertilizers. However, after ordinary microbial fertilizers are applied to the soil, the effect is often not good. The main reason is that the applied exogenous microorganisms are difficult to survive in the soil or the surviv...

Problems solved by technology

However, after ordinary microbial fertilizers are applied to the soil, the effect is often not good. The main reason is that the applied exogenous microorganisms are difficult to survive in the soil or the survival rate is very low. Insufficient carbon source, on the other hand, the limited beneficial microorganisms from exogenous sources are exposed to the large number of harmful microorganisms in the soil, and the survival conditions are very poor
