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.
