以某种材料为浮载体,并采取相应的工程措施,在自然水域的水面上栽培水稻的方法叫水上种稻。此项技术是由中国水稻研究所研究成功的。他们在浙江省境内的大型水库、小型水库、内荡、外荡、山塘和鱼塘等水域上种植的水稻均取得了较高的产量,亩产均达500 To some kind of material for the floating carrier, and take the appropriate engineering measures, the method of cultivation of rice on the water surface of natural waters called water on rice. This technology is researched by China Rice Research Institute successfully. They have achieved relatively high yields of paddy rice planted in large reservoirs, small reservoirs, inner swamps, swarms, ponds and fish ponds in Zhejiang Province, with a yield of 500
