A preliminary research was conduct ed on the application of a kind of superior woody vegetable ———Toona sinensis to floating culture bed. The research analyzed its advantage and feasi bility. An overwintering experiment of Toona sinensis planted on the floating bed was conducted. The results showed that in Wuhan , Toona sinensis could live through the winter and sprout without taking any antifreezing measures. The planted float system for Toona sinensis put forward higher re quirements for the carry ability of the bed. It ’s worth further researching on the forming of ecological adaptability and difference in the shape of tree under a sudden change in environment . Key words :aquatic agriculture ;artificial floating bed ; Toona sinensis ;ecological adaptability 1 　引言 的湖面已经成为中度以上的富营养化 ,适宜于农业利 我国是一
