摘要: 水面无土栽培水稻(简称水面稻)是运用浮于水面的栽培床种植水稻的新方法。本研究从三种形式的栽培床中筛选出一种较好的草把式栽培床作为无土栽培水稻的载体。它具有结构紧凑、浮力好、材料易得、制作简便、可连续使用2~3年。成本较低等优点。可用于栽培各类型水稻或其它水生作物。多年试验表明,水面种稻通风透光好,根系发达,稻株生长健壮,病虫害轻,结实率高,稻谷产量高而稳。结合水体养鱼,效益更高,应用前景广阔。Abstract: Soilless rice cultivation is a new rice-growing method using floating materials on water surface.Straw-bundle bed selected from three culture materials is considered to be the best one.It has the advantages of compact compages, good buoyancy.available source, easy making.2 to 3-years using duration and lower cost.All rice and other aquatic crops canbe cultured using this straw-bundle bed.The results from several years' experiences showed that:1.Comparing with rice growing in paddy field, rice yield of floating method is fairly stable and high due to the good aeration, well developed root-system.healthy plant.less disease.insect damage and high filled-grain rate.2.Combining with raising fish in water body.high economic benefits will be obtained.So it will open up broad prospects for further development.
