[目的]探明杂交中稻川江优527的高产栽培技术。[方法]研究了施氮量、栽秧方式和密度对水稻生长的影响。[结果]不同栽秧方式的产量水平表现为等行距>宽窄行>三角形。在相同栽秧密度条件下,等行距比三角形显著增产,但增产程度与栽秧密度呈显著负相关关系。[结论]川江优527的高产栽培技术:施氮量90~150 kg/hm2,栽秧密度15.16万穴/hm2左右,栽秧方式为等行距。
[Objective] The research aimed to investigate the high-yielding cultivation techniques of hybrid rice Zhongjiang You 527. [Method] The effects of nitrogen application, planting methods and planting density on the growth of rice were studied. [Result] The yield of different planting methods showed equidistance> width and width> triangle. Under the same planting density, the row spacing was significantly higher than that of the triangle, but the yield increase was significantly negatively correlated with the planting density. [Conclusion] The high yielding cultivation techniques of the superior 527 in Chuanjiang showed that the nitrogen application rate was 90-150 kg / hm2 and the planting density was about 151 600 hm2 / hm2.
