摘　　要：不同品种、不同盐水比重选种试验结果表明,选种时的盐水比重大,秧苗素质好,田间生长优势明显,出苗率提高6.9%,增产幅度达2.4%～5.6%。小粒型品种的盐水选种比大粒型品种增产幅度高1.4%～4.7%,晚熟品种比早熟品种增产幅度高1.1%～3.6%。但不同盐水比重选种对米质的影响不大。The result of selection experiment of different variety and saline specific gravity showed that seedling quality with large proportion was better than others. The seedling had significant growth advantage. Emergence rate increased 6.9% and yield increased 2.4%-5.6%. Through the saline selection, yield of small grain rice variety increased 1.4%-4.7%, and yield of late-maturing variety increased 1.1% -3.6%. But different saline specific gravity had less impact on rice quality.
