晚稻秧苗的壮瘦与否,除要适期播插和秧田具有一定肥力水平外,在很大程度上决定于单位面积上的播种量。我国籼型杂交水稻应用于生产后,不少单位的科研人员进行了稀播、匀苗培育壮秧对杂交稻产量潜力影响的研究,结果不仅减少了杂交稻的用种量,而且还使杂交稻的产量潜力得到充分的
Late rice seedling thin or not, in addition to the appropriate sowing and seedling field has a certain level of fertility, largely determined by the amount of sown per unit area. After the application of indica hybrid rice in our country, many units of researchers carried out research on the effect of sparse seedling and uniform seedling on the yield potential of hybrid rice. The results not only reduced the used amount of hybrid rice, but also made hybridization The yield potential of rice is sufficient
