Problems solved by technology

[0002] At present, there are four major problems in the production and application of microbial bacterial fertilizers. These problems are: 1. The production and packaging process must be carried out under strict aseptic conditions, and the handling and storage processes require good conditions, so the production cost is high and it is easy Pollution, often batches of bacterial fertilizers become waste products; 2. It is difficult to produce and store bacterial fertilizers at high temperatures in the south, and the number of effective viable bacteria is small when used; 3. The number of bacterial fertilizer microorganisms decreases rapidly after entering the soil, and it is not easy to form a dominant community. Bacterial fertilizer has a short validity period and unstable application effect; 4. When applying in the field, it is necessary to avoid agricultural measures such as pesticides and fertilizers and be restricted by environmental factors

Abstract

The invention relates to a compound microbial fertilizer and a preparation method thereof. The compound microbial fertilizer is characterized by being prepared from the following materials in percentage by weight: 40.0-50.0 % of rape seed cakes, 10.0-20.0% of crops straws, 1.5-3.0% of mycothallus, 0.5-1.0% of bacterium thallus and 35.0-40.0% of water. By using the solid fermentation method twice, the invention organically combines the fungi (Trichoderma harzianum and Aspergillus aculeatus for biological control effect) and the bacteria (Bacillus subtillis and Bacillus megatherium for growth-promoting effect), and realizes a simple preparation method. The compound microbial fertilizer has the advantages of environmental condition resistance, high count of active viable bacteria, less influence by the environment after application, slow release of thallus and long-term effective colonization at rhizosphere of plants, promotes plant growth and simultaneously has a certain biological control effect on soil-borne diseases.
