The characteristic research of rhizosphere microbes in floating bed cultivated swamp cabbage
摘要
Abstract
This paper researched the characteristics of rhizosphere microbes in floating bed cultivated swamp cabbage,took an example of bacteria. The test was divided into 3 groups according to the cultiva-tion area ratio of swamp cabbage:50% group,25% group and zero,as a experimental control. We regu-larly observed the dynamic characteristics of bacteria and COD by PFU method during the test,and then analyzed the relationship between them. The results showed that:first,the total bacterias of both 50% and 25% group were an order of magnitude higher than those of the control one. Second,swamp cabbage grew within 4 weeks,its cultivation area ratio had relative correlation to the total bacteria,and they showed no significant difference after 4 weeks. Third,the rate of COD removal was 63. 54% by the 50% group, 47. 92% by the 25% group,25% by the control group,so the growth of rhizosphere microbes in floating bed cultivated plants had significant, linear correlation to the degradation of organic compounds in wastewater. Research quantitatively demonstrated the relationship between them from biological aspects to develop the theoretical foundation on eutrophied water treatment by floating bed cultivation,it benefits to popularize and apply this technology. 2figs. ,3tabs. ,8refs.关键词
