摘　　要：利用稻田退水进行浮床栽培水稻与空心菜产量及品质研究。结果表明:浮床水稻产量达到2 236.54 kg/hm2,收获的稻谷达到国家标准四级稻谷;浮床空心菜3次收获产量合计2 726 g/m2。收获的稻谷和新鲜空心菜重金属含量没有超过国家标准限量。与常规种植相比,浮床水稻、空心菜产量和品质较差,但符合国家食品安全标准。The floating-bed experiment in paddy drains was conducted to research on yield and quality of floating bed rice and water spinach. The results showed that The yield of floating bed rice reached 2 235.54 kg/hm^2, and the harvested rice reached the national standard four-grade rice. The total yield of three harvests of floating bed water spinach reached 2 726 g/m^2. The heavy metal content of harvested rice and fresh vegetables did not exceed the national standard limit. Compared to the conventional farmland planting, the yield and quality of floating bed rice and water spinach were poor. but met national food safety standards.
