| 摘 要： | 以全优527为材料,测定6种不同种植基本苗数的产量和主要产量性状,研究机插双晚杂交稻的最适插植基本苗数。结果表明,当基本苗数在83．25万株／hm^2以下时,产量随基本苗的增加而显著增加,超过此值,产量增加不明显。双晚机插杂交稻的种植基本苗数以83．25万株/hm^2为宜。

| Abstract: | Quan-you 527 were adopted to investigate the yield and main characters of six different basic seedling numbers, and then, the optimum transplanted basic seedling number of mechanical transplanted double late hybrid rice was studied. The results showed that when the basic seedling number below 832 500 shoots/hm~2, the yield increased obviously with increasing basic seedling number, when beyond this number, the yield increased not obviously. It indicated that the suitable basic seedling number for mechanical transplanted double season late hybrid rice is 832 500 shoots/hm~2. |
