| 摘 要： | 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.

| Abstract: | 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 |
