耕作和育秧方式对机插水稻群体质量和产量的影响

摘要

The effects of farming method,rice variety and seedling-raising method were studied on the population growth quality and grain yield of the mechanized transplanting rice by way of three-factor split plot design.The results showed that the no-tillage mechanical transplanting treatment was poorer than the conventional mechanical transplanting treatment in transplanting quality in general,but the former was similar to the latter in population growth quality.In regard to grain yield,the no-tillage mechanical transplanting treatment was lower than the conventional mechanical transplanting treatment.Raising both pot-mat seedling and plastic-tray seedling did not make much difference in population growth and grain yield of mechanized transplanting rice,so both of the seedling-raising methods can be adopted according to practical conditions.%用3因素裂区设计,研究了耕作方式、品种和育秧方式对机插稻群体质量和产量的影响.结果表明,免耕机插栽插质量整体差于常规翻耕机插,群体质量与常规翻耕机插差异不大,产量低于常规翻耕机插.塑料软盘育秧与钵形毯状育秧对水稻生长和产量的影响较小,生产上可因地制宜选用.
