3 mg/kg) for 24 h and 36 h respectively,the effects of seed soaking with ABA on rice seedling growth and rice yield were studied, with the method of soaking seeds in clear water as the control.

3mg/kgABA浸种24h和36h,以清水浸种作对照,研究了ABA浸种对水稻秧苗生长和产量的影响。

The new seedling agent- ZS1 #、ZS2 #、ZS3 #, which are the mixture consisted of different plant growth regulators and fungicide, are applied to growth of rice seedling with using plastics seedling on the basis of the preliminary test study of plant growth regulators GA、NAA、6-BA、PG 1and PG 2 on the growth of rice seedling by soaking seed.
