对免耕抛秧稻籽粒灌浆结实特性的研究结果表明 :免耕抛秧稻的结实率高于常耕抛秧稻 ,主要以一次枝梗的结实率较高。免耕抛秧稻全穗枝梗数与总粒数均高于常耕抛秧稻 ,其中二次枝梗的差异较大。免耕抛秧稻灌浆启动较早 ,齐穗后籽粒淀粉含量高于常耕抛秧稻 ,而可溶性糖的含量低于常耕抛秧稻。
The study on the grain-filling characteristics of no-tillage and throwing rice showed that the seed-setting and throw-away rice seed setting rate was higher than that of the conventional tillage and rice-throwing rice, and the primary seed setting rate was high. The number of panicle branches and the total number of grain in the no-tilled and throw rice seedlings were all higher than that of the permanent pan-throwing rice seedlings, of which the secondary branches and stems differed greatly. The no-tillage seedling throwing started earlier, after heading, the grain starch content was higher than that of the permanent cultivating and throwing rice, while the content of soluble sugar was lower than that of the conventional tillage and throwing rice.
