以杂交中粳泗优 90 2 2为材料 ,3种不同密度和 3种不同的行株距配比主式的试验表明 :不同行株距配比方式之间的产量趋势为 :适度的宽窄行配比方式 >近似正方形配比方式 (行距与株距近似相等 ) >宽行窄株配比方式。进一步说明 :一种理想的行株距配比方式必须把叶片的合理配置与培育高质量群体充分结合起来
The experiment of three main varieties of hybrid japonica rice, Siyou 90 2 2, with three different densities and three different line spacing ratios, showed that the yield trend between different line spacing patterns was moderate width line ratio Method> Approximate square ratio (line spacing and plant spacing are approximately the same)> wide line narrow plant ratio. Further Description: An ideal line spacing ratio must be the rational allocation of leaves and cultivate high-quality groups fully integrated
