Growing rice with floating bed on the natural waters is a new technique of rice soilless culture developed successfully in 1990. In 1991-1993, the trials on the ecological adaptability were conducted on 5 kinds of natural waters in Zhejiang Province to examine the feasibility of the technique to be applied in the varied waters such as large reservoir, lake, fish pond and so on. The double- and single-cropping rice of 4. 33 hm2 experienced different ecological environments and climates. Except for double-cropping early rice, rice growing on the waters in different seasons yielded highlier than paddy rice. The highest yields of double and single-cropping rice are 14 985 and 10 065 kg/hm2, respectively. The technical model of growing rice on the natural waters was established , including transplanting, fixing of floating bed, and so on.
