Problems solved by technology

[0006] In the existing microbial fertilizer preparation process, the microbial agent is mainly added during the granulation process. High temperature treatment will lead to the death of a large number of microorganisms. After application, the bacterial agent has a short effective time, poor repeatability and stability.
In addition, because the microorganisms in microbial fertilizers cannot directly contact with chemical fertilizers, microbial fertilizers have problems such as low microbial survival rate and poor activity, which leads to unsatisfactory improvement of soil functions. Therefore, it is necessary to develop a microbial survival rate High-efficiency and simple preparation process of functional fertilizers to improve the current situation of deteriorating soil functions, thereby promoting the recovery of soil functions

Abstract

The invention discloses a composite fertilizer for adjusting soil functions and a preparation method thereof. The composite fertilizer comprises a composite fertilizer particle core layer, an isolation middle layer and a microorganism organic film coating layer, wherein the isolation middle layer is coated to the surface of the composite fertilizer particle core layer; the microorganism organic film coating layer is coated to the surface of the isolation middle layer. The composite fertilizer is characterized in that the weight ratio of the composite fertilizer particle core layer to the microorganism organic film coating layer is (20 to 300):1; the microorganism organic film coating layer comprises organic matter mixture and enzyme bacteria according to a weight ratio of 0.2 to 10. The composite fertilizer has the advantages that more than thirty types of beneficial microorganism composite bacterial colony are contained, the activity of microorganism is strong, the mycorrhiza is formed, the absorbing area of root system is increased, the nutrients are promoted to be absorbed and utilized, the fertility is improved, the formation of humic acid is promoted, the acid and alkaline value of soil is adjusted, and the physical and chemical properties of soil are improved.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a compound fertilizer for regulating soil functions, and also relates to a preparation method of the compound fertilizer. Background technique [0002] Water is the source of life, soil is the foundation of a country, soil is the fundamental premise for the existence and development of human society, and the most important basic resource. As a layer of loose material on the earth's surface, soil has many important functions: first, soil is an important source of nutrients necessary for terrestrial organisms, and acts as a nutrient pool; second, it has the role of biological support, including supporting The mechanical support of green plants also includes a wide variety and huge number of biological groups in the soil, and supports the life and reproduction of underground organisms; thirdly, the soil can regulate the flow of water and solute, thus playing the func...
