对培矮64S不同抛秧密度的试验结果表明,抛秧量与制种产量、有效穗数、总颖花数成显著或极显著正相关;抛秧随秧龄的不同,播始天数有变化。相同秧龄时抛植比插植生育期延长2天左右;培矮64S的最适抛秧密度每667m2为48～50张秧盘。
The test results on the density of different seedling throwing of Peiai 64S showed that there was a significant or very significant positive correlation between the seedling throwing yield and the seed yield, effective panicle number and total spikelet number. The throwing days varied with the different seedling ages. The same seedling age when the plantation than the implanted growth period of about 2 days extension; Peihao 64S optimum density of throwing planted per 667m2 for 48 ~ 50 seedling tray.
