宜香优2115不同栽培密度对产量的影响

The Effect of Different Planting Density of Yixiangyou-2115 on Yield

为了达到高产、高品质及抗性好的栽培目的,筛选出水稻宜香优2115的适宜栽培密度,研究了不同的栽培密度下,对其产量及产量构成因素的影响。研究结果表明,株行距对宜香优2115的产量影响达到了极显著水平,在本试验中,土壤肥力中等的情况下,栽培密度为13536穴/667m2时,产量达到最大;在一定的栽培密度范围内,有效穗数随着栽培密度的增加而增多;每穗实粒数与栽培密度呈负相关关系。

In order to achieve high yield,good resistance to high quality and cultivation objective,select the suitable planting density of rice appropriate Yixiangyou 2115,studied the varieties under different planting density,the influence on the yield and yield components. Research results show that the plant row spacing influence on appropriate Yixiangyou 2115 output reached extremely significant level,in this experiment,soil fertility under the condition of medium,the planting density of 13536 holes/667 m2,the maximum yield of rice variety; In the range of cultivated density,the number of effective panicles increased with the increase of cultivation density. The grain number per ear was negatively correlated with the cultivation density.
