摘要
2014年,在重庆市万州3个烟蚜典型发生烟区开展了黄板诱蚜技术示范推广应用研究,研究了黄板诱蚜技术对烟蚜控制、蚜传病害病毒病防治的效果以及对烟田经济效益的影响。结果表明,黄板诱蚜示范区对烟蚜的迁飞起到了较好阻隔效果,降低了烟蚜虫口密度,处理后14,21 d,对烟蚜的校正防效达到80%;黄板诱蚜有效降低了烟草蚜传病毒病发生率,对烟草马铃薯Y病毒病有较好的控制效果;黄板诱蚜示范烟田每公顷产量可增加255.40 kg,产值可增加5 625元/hm2。
In 2014, Wanzhou carried out demonstration application of yellow board induced aphid technology research in 3 typical tobacco aphid occurrence area of Chongqing, which maninly studied the effect of yellow board induced aphid technology on control effect of aphid, borne disease virus disease prevention and economic benefits of tobacco field. The results showed that yellow board induced aphid demonstration area showed good effect of population migration barrier, reduced the aphid population density, after the treatment of14, 21 d, correction control effect reached 80%; yellow board induced aphid effectively reduced the incidence of tobacco aphid borne virus disease, had good control effect on tobacco potato virus Y; Chongqing Wanzhou District yelllow board induced technology promotion could increase output 255.40 kg/hm2, generate economic benefits 5 625 yuan/hm2, could widely recommended.
