不同施氮量和密度对杂交中籼两优6326产量及穗粒结构的影响

Effect of the Application Amount of N-fertilizer and the Planting Density on the Yield and Agronomical Character of Medium Indica Hybrid Rice-Liangyou 6326

研究了不同施氮量和密度对杂交中籼两优6326产量及穗粒结构的影响。结果表明,不同施氮量和密度对两优6326产量的影响均达极显著水平;而对株高、穗长及千粒重的影响不大。降低密度和提高施氮量有助于产量的增加。

The effect of the planting density and the application amount of N-fertilizer on the yield and agronomical character of medium indica hybrid rice-liangyou 6326 were studied. The result showed that the yield of medium indica hybrid rice-liangyou 6326 was very signicantly increased with the increasing of application amount of N-fertilizer or the decreasing of the planting density, but there was significant difference in planting height, panicle length and 1 000-grain weight. The result indicated that the yield can be increased through the increasing of N-fertilization and planting density-decreasing.
