该文探讨了ＺＳＢ－Ｒ生物型种衣剂对不同活力水平杂交水稻种子的影响以及包衣种子不同浸种时间处理的活力变化。研究表明：该种衣剂能提高不同活力水平杂交水稻种子的发芽势和发芽率，但对发芽指数和活力指数影响不大，即包衣种子活力基本稳定。剂量加倍会使种子活力明显下降。浸种会降低包衣种子活力，生产用种应避免浸种或缩短浸种时间，否则会产生不良作用。
This paper explored the effect of ZSB-R seed coating on the seed vigor of hybrid rice with different vigor level and the change of vitality of seed coating at different soaking time. The results showed that the seed coating could improve the germination energy and germination rate of hybrid rice seeds with different vigor levels, but had little effect on the germination index and vigor index, that is, the seed vigor of the coating was basically stable. Doubling the dose will significantly reduce seed vigor. Seed soaking will reduce the vitality of the seed coating, seed production should be avoided soaking seeds or shortening the soaking time, otherwise it will have adverse effects.
