摘　　要：采用拌种和浸种2种方法,探讨了高巧+顶苗新药剂组合处理种子后对水稻安全性、秧苗素质的影响,以及对秧田期稻蓟马和灰飞虱的控虫效果。结果表明,每千克稻种用高巧4 m L+顶苗新4 m L拌种、浸种处理对水稻安全性高,且能刺激幼苗生长,有利于培育壮苗;播后30 d拌种、浸种处理对稻蓟马的防效分别为96.41%、90.33%,播后20 d对灰飞虱的防效分别为80.73%、78.21%,可较农户常规防治减少用药2次以上。因此,高巧+顶苗新拌种、浸种技术具有良好的推广应用前景。By using seed dressing and soaking methods,this study described effects of combination of Gaucho and Dingmiaoxin on rice safety,seedling quality and control of Stenchaetothrips biformis,Laodelphax striatellus. As a result,seed dressing and soaking using the combination of 4 m L Gaucho and4 m L Dingmiaoxin for per kilogram rice seed was safe to rice,and could stimulate seedling growth,thus helpful for cultivating strong seedlings. The two treatments also had good control effects on Stenchaetothrips biformis and Laodelphax striatellus. The control efficiencies for Stenchaetothrips biformis 30 days after sowing were 96. 41% and 90. 33%,respectively. For Laodelphax striatellus,the control effects 20 days after sowing were 80. 73% and 78. 21%,respectively. The control methods reduced the frequency of pesticide spraying by more than twice,and had a good prospect for promotion and application.
