摘　　要：比较了30d,45d,60d 秧龄弹性秧与半水秧的产量,秋苗素质,于物质累积以及生育期变化.结果表明,弹性秧比半水秧平均增产12.6%,其中60d 秧龄的增产最大,达35.4%。弹性秧秧苗素质好,移栽后干物质累积快,并且可提早2～4d 成熟.The yields,quality of seedlings,cumulative rates of dry matter and growth stages of the elastic and the humid growing rice seedlings in three ages(30,45,60d) were studied.The results indicated that the average yield of the elastic growing seedlings increased by 12.6% compared with that of the humid growing seedlings,and out of three different seedling ages,the yield of the elastic growing rice seedlings transplanted in the age of 60 d was 35.4% higher than that of humid growing rice seedlings.The quality of elastic seedlings was better,its rate of dry matter accumulation was quicker after trans- planting and generally the ripening date was 2-4 d earlier as compared with the humid growing seedlings.
