研究表明，以８０—１００ｐｐｍ浓度的“９２６”植物生长调节剂，于苗期、抽穗期、灌浆期三次喷施水稻，增产率达２０—３５％。构成增产的主要因素是提高成穗率，增加穗粒数和粒重。
The sesult of the field trial has shown that the rice output can be increased by 23-35 % by appliang 80-100ppm 926 to rice at seedling stage, heading stage and in the milk gtage,The main factor that leads to increasing production is the effective nate of ears and grain number of ears and increasing grain weight.
