Abstract
At present, the most modes of aquaculture in our country are high-density intensive culture. With the development of this model, pollution of the ecological environment of aquaculture is becoming more obvious gradually. As a result, more and more Chinese and foreign scholars have studied the pollution of aquaculture environment, and the means to deal with the pollution problem have become more and more abundant. The purpose of this study is to explore the impact of ecological base technology on the culture environment of aquaculture ponds. The main research object is ecological base, and the changes of microbial community structure in the water and ecological base in the culture environment are analyzed, so as to explore the mechanism of ecological base in the culture environment. The water quality index showed that ammonia nitrogen, nitrate nitrogen, nitrite nitrogen and phosphate were all in a stable state of decline during the whole experiment, and the contents were all within the safe concentration range. The microbial diversity in the experimental group was lower than that in the control group, indicating that the microorganisms in the experimental group would transfer and attach to the ecological base, and the unique structure of the ecological base provided an ideal habitat for microorganisms, thus increasing the diversity of microbial community structure. The results showed that the influence of ecological base on water quality index was not obvious, but on bacterial community.
