摘　　要：采用人工模拟中雨的方式研究了降雨对化学杂交剂SX-1使用效果的影响。结果表明,化学杂交剂SX-1喷施后人工模拟中雨时间越近,化杀剂杀雄效果越差,表现在不育率降低、不育性持续时间变短;化杀剂SX-1喷施后8 h降中雨对药效影响不大。同时,化学杂交剂SX-1对油菜的生长发育有一定的抑制作用,降雨时间距喷施化杀剂的时间越短,其抑制作用越小。The effect of rainfall on the use of chemical hybridizer SX-1 was studied by means of simulated moderate rainfall. The results showed that the shorter the simulated moderate rain time after spraying chemical hybridizing agent SX-1, the worse the effect of chemical pesticides on male sterility, the lower the sterility rate and the shorter the duration of sterility. Simulated moderate rain after spraying chemical pesticides 8 hours had no significant effect on the efficacy of chemical pesticide SX-1. At the same time, the chemical hybridizing agent SX-1 inhibited the growth and development of rapeseed. The shorter the time between rainfall and spraying chemical pesticides, the smaller the effect of inhibition.
