1988年在我国南方十二省杂交稻制繁种区计4.8万亩面积上进行了“九二○”增效剂的应用试验、示范.结果表明,该增效剂能提高“九二○”的功效。使“九二○”用量减少50％,从而降低了生产成本;同时,这种增效剂还可以提早不育系花时0.5～1.0小时,提高不育系柱头外露率,有利于异交结实,使制繁种产量提高10％左右.
In 1988, the test and demonstration of “920” synergist was carried out on 48,000 mu of hybrid rice breed areas in 12 southern provinces of China. The results showed that the synergist can enhance the “920” Efficacy. At the same time, the synergist can also prematurely spend 0.5-1.0 hours on sterile lines, increasing the stigma exsertion rate of male sterile lines, which is good for outcrossing and fruiting , So that system of production increased by about 10%.
