Description

Technical Field

[0001] The invention belongs to the technical field of microbial fertilizer preparation, and in particular relates to a composting device for preparing microbial fertilizer. Background Art

[0002] Microbial fertilizers, also known as biological fertilizers, inoculants or bacterial fertilizers, refer to a type of fertilizer product that uses the life activities of microorganisms as the core to enable crops to obtain specific fertilizer effects. There is an essential difference between microbial fertilizers and micro-fertilizers: the former is a living being, while the latter is a mineral element. Microbial resources are abundant, with a wide variety of types and functions, and can be developed into fertilizers with different functions and uses. Moreover, microbial strains can be artificially selected and continuously purified and rejuvenated to improve their vitality. Especially with the further development of biotechnology, it has become possible to obtain the required strains through genetic engineering methods.

[0003] There are many types of microbial fertilizers, and microbial fertilizer products are generally divided into two categories: one is microbial fertilizer in a narrow sense, which refers to the increase in the supply of plant nutrients through the life activities of microorganisms, including increasing the total supply of plant nutrients in the soil and production environment, resulting in improved plant nutritional status and increased yields. The representative variety of this type of microbial fertilizer is rhizobium fertilizer; the other is microbial fertilizer in a broad sense, which refers to the microbial life activities of the microorganisms, which can not only increase the supply of plant nutrients, but also produce plant growth hormones, promote the absorption and utilization of nutrients by plants, or antagonize the pathogenic effects of certain pathogenic microorganisms, reduce crop diseases and insect pests and promote increased crop yields.

[0004] According to the type of microorganisms, they can be divided into five categories: ① bacterial fertilizers (such as rhizobium fertilizers, nitrogen-fixing fertilizers, phosphate-dissolving fertilizers, potassium-dissolving fertilizers, and photosynthetic fertilizers); ② actinomycete fertilizers (such as antibiotic fertilizers); ③ fungal fertilizers (mycorrhizal fungal fertilizers: including ectomycorrhizal agents and endomycorrhizal agents); ④ algae fertilizers (such as nitrogen-fixing cyanobacteria fertilizers); ⑤ compound microbial fertilizers, that is, fertilizers formed by a combination of two or more microorganisms in a certain proportion.

[0005] The basis of the action of microbial fertilizers is living microorganisms that play a specific role. These microorganisms directly or indirectly affect the physiological metabolism of plants or soil environmental conditions through their growth, reproduction and physiological activities. In order to give full play to the role of microbial fertilizers. One of the main functions of microbial fertilizers. For example, various autogenous, combined or symbiotic nitrogen-fixing microbial fertilizers can increase the nitrogen content in the soil; the application of a variety of phosphorus-dissolving and potassium-dissolving microorganisms, such as Bacillus and Pseudomonas, can decompose the insoluble phosphorus and potassium in the soil and convert them into phosphorus and potassium compounds that can be absorbed and utilized by crops, thereby increasing the supply of nutrients in the crop growth environment. The application of some microbial fertilizers increases the organic matter in the soil and improves the fertility of the soil.

[0006] The role of microorganisms in agriculture has gradually been recognized by people. More than 70 countries in the world have produced, applied and promoted microbial fertilizers. There are also 250 enterprises in my country that produce about hundreds of thousands of tons of microbial fertilizers for production. Although this is not comparable to the output and use of chemical fertilizers in the same period, it has indeed begun to play a role in agricultural production and has achieved certain economic and social effects. With the deepening of relevant research and the continuous expansion of market demand, the production of microbial fertilizers has shown a large-scale industrial production model.
