Effect of Different Planting Density on Hybrid Rice Yield of Zheyou18

研究不同栽培密度对杂交稻浙优18产量的影响。结果表明,有效穗数随栽培密度增加而增加,丛有效穗、穗实粒数、结实率、千粒重随栽培密度的增加而降低。在适宜的栽培密度范围内,产量随栽培密度的增加而提高,最适栽培密度为20 cm×23 cm,每667m^2产量为569.7 kg,增产效果显著。

We studied the effect of different population density on gr~.in production of hybrid rice zheyoul8. Results indicated that with the planting density increasing, total panicles increased, panicles per hill, filled spikelets per panicle, seed setting rat, 1000-kernal weigh decreased, It tends to have more rice production as density increasing within certain range, the optimum planting density is 20cm×20cm, the corresponding yield reached 569.7kg per 667m2.
