Composite microbial agent and production method thereof

Abstract

The invention relates to a composite microbial agent and a production method thereof. The composite microbial agent consists of a granular material core, a paraffin protective coating and a microbial agent coating layer between the core and the protective layer. The excellent product structure can ensure that the effective microbe content in the composite microbial agent is high, and the product has stable properties and high fertilizer efficiency and meets the requirements of various crops; and compared with the conventional biofertilizer, the composite microbial agent can improve the yield of food crops by 10 to 15 percent, improve the yield of cash crops by 8 to 14 percent, improve the yield of vegetables by 15 to 20 percent, and improve the yield of fruits by 15 to 25 percent. Throughthe production method, the granulation rate of the product is 95 percent, the granule strength of the product is high, and because the water content of the granular material is low, the energy consumption in the energy process is reduced, the production efficiency of drying equipment is improved and the investment of the drying equipment is reduced.

Description

【Technical field】

[0001] The invention belongs to the technical field of fertilizers. More specifically, the present invention relates to a composite microbial inoculum, and also relates to a production method of the composite microbial inoculum. 【Background technique】

[0002] With the extensive use of chemical fertilizers, it is a well-known fact that it causes soil compaction, environmental pollution and the continuous reduction of utilization rate. For this reason, scientists from various countries have been working hard to explore ways to improve the utilization rate of chemical fertilizers to achieve balanced fertilization and rational fertilization to overcome its drawbacks. Microbial fertilizers have a unique role in solving these problems. Chinese scientific researchers have been exploring for many years and have achieved fruitful results. According to the types of crops and soil conditions in our country, the use of microbial fertilizers and chemical fertilizers ...
