| 摘 要： | 通过不同的抛栽密度对无盘旱育免耕抛栽稻产量的影响对比试验,表明:不同的抛栽密度对无盘旱育免耕抛栽稻的穗粒数、结实率、千粒重影响不大,对产量有一定的影响,早稻抛秧密度为2.0万丛/667m2时,其经济性状指标与产量最高;晚稻在低肥管理下抛秧密度以2.42万丛/667m2,高肥管理下抛栽密度以1.98万丛/667m2较理想。

| Abstract: | Through the plots experiments of the broadcasting density's impacts on the yield of non-tray cultivation with no-tillage rice,the results show that different broadcasting densities have little impacts on grain number per spike, seed set,1000-grain weight of rice,but a certain impact on the yield.The broadcasting density of 20,000-cluster/mu for earlier rice has the highest economic feature index and yield.For later rice,broadcasting density of 24,200-cluster/mu at lower fertilization and 19,800-cluster/mu at higher fertilization will have the ideal results. |
