为探明自然水域浮床无土栽培水稻（简称水上种稻，下同）技术应用于大型水库等水域的可行性，１９９１～１９９３年，在浙江省境内的５种水域类型上进行了生态适应性试验。累计试种双季和单季稻４．３３ｈｍ２，均经受住了不同生态环境和不同年份气候条件的考验。其中，除连作早稻单产低于水田水稻对照外，其他两季的单产均超过了水田水稻对照。最高的双手连作稻和单季晚稻单产分别达１４９８５和１００６５ｋｇ／ｈｍ２。从而证明，在各类型水域上进行水上种稻不但可行，且能取得与水田水稻相仿甚至更高的产量。
In order to find out the feasibility of applying floating bed soilless culture rice in natural waters to the water reservoirs of large reservoirs and so on, from 1991 to 1993, the ecological adaptability of five types of waters in Zhejiang Province test. Accumulative trial double-cropping and single cropping 4.33hm2, have stood the test of different ecological environment and climatic conditions in different years. Among them, the yield of rice in the other two seasons exceeded that of paddy rice except for the yield of continuous crop of early rice was lower than that of paddy rice. The highest double-cropping hybrid rice and single-cropped late rice yield reached 14985 and 10065kg / hm2, respectively. This proves that it is not only feasible to grow rice on water in all types of waters, but also to achieve similar or even higher yields than paddy rice.
