研究了不同的保温育苗措施对4个双季早稻品种秧苗素质、产量及产量构成因子的影响。结果显示:采用强氯精浸种方式的早稻出苗率较高,采用稻种伴侣浸种的早稻有效穗数、生物量、每穗总粒数、结实率、千粒重和产量均较高;采用湿润育秧方式的早稻产量、每穗粒数、结实率较高;采用湿润育秧+双膜覆盖处理的早稻产量和生物量较高。
The effects of different incubation and seedling raising measures on the quality, yield and yield components of four double-season early rice varieties were studied. The results showed that the emergence rate of early rice with strong chlorine seed soaking was higher, the effective panicle number, biomass, total grains per panicle, seed setting rate, 1000-grain weight and yield of early rice soaked with rice seed mate were higher; The yield of early rice and grains per spike and seed setting rate were higher. The yield and biomass of early rice with moist seedling and double-film mulching were higher.
