Problems solved by technology

[0002] At present, there are 5 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. The effective storage period is short, 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. Short and unstable application effect; 4. Agricultural measures such as pesticides and fertilizers should be avoided in field application and restricted by environmental factors
5. It is difficult to produce and preserve bacterial fertilizer under high temperature in the south, and it is difficult to promote autumn crops such as rapeseed
