Artificial floating bed technology has been used to repair eutrophic water. However, there are relatively few studies on the overwintering of economic plants on the floating bed. In order to realize the resource utilization of wastewater, celery, Artemisia selengensis, Garlic, Chinese yam, lettuce and other crops were selected as the test plants for the floating bed. Quantitative experimental study was conducted on the aquaculture wastewater in winter. The results showed that after 90 days of acclimation, the tested plants showed different growth characteristics, with the survival rates above 84.48%. The distribution of nitrogen and phosphorus in water and subsurface plants of 5 species were different. The contents of nitrogen and phosphorus in plants The accumulative amounts were 1.15 ~ 5.18 g·m-2 and 0.04 ~ 0.21 g·m-2, respectively, with the order of garlic > celery > seabuckthorn > sedum chrysanthemum> lettuce and celery> garlic> sesame oil> sesame oil> lettuce.
Key words: Winter / artificial floating bed / economic plant / growth characteristics / absorptive capacity
