Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of microbial inoculant culture, and particularly relates to a culture device for improving saline-alkali soil by microbial inoculant. BACKGROUND

[0002] In the process of saline-alkali soil improvement, the application of microbial inoculant is crucial, which can effectively regulate the saline-alkali environment of soil through metabolic activity. However, during the culture stage of microbial inoculant, it is usually necessary to simulate the saline-alkali environment in the culture solution, that is, to add a certain concentration of saline-alkali components. Most of the existing culture devices adopt static culture mode, and the culture dish is in a static state, which leads to the precipitation of saline-alkali substances in the culture solution.

[0003] The saline-alkali precipitation directly affects the uniformity of the contact between the microorganisms and the culture solution, and further reduces the activity and reproduction efficiency of the inoculant. In addition, the static culture is difficult to simulate the dynamic environment of saline-alkali soil, so that the microorganisms cannot fully adapt to the high saline-alkali conditions during the culture stage, which ultimately affects the improvement effect in the real saline-alkali soil. Therefore, there is an urgent need for a culture device for improving saline-alkali soil by microbial inoculant to solve the above problems. SUMMARY
