绿色植保技术在高黎贡山绿色生态优质烟叶生产中的应用

在高黎贡山绿色生态优质烟叶生产示范区,秉承"公共植保,绿色植保"的理念,按照"预防为主、综合防治"的植保方针,从烟田生态系统整体出发,构建了以农业防治为基础、以生物防治为重点、以物理防治为辅助、以化学防治为补充的病虫害绿色防控技术,核心技术包括:黄板诱杀烟蚜、烟粉虱的物理防治技术;频振式杀虫灯防治烟草害虫的物理防治技术;性信息素诱杀斜纹夜蛾、烟青虫、棉铃虫的生物防治技术;烟蚜茧蜂防治烟蚜的生物防治技术;生物制剂防治烟草病虫害的应用技术。通过绿色防控技术的示范推广,把病害虫的为害损失控制在经济允许的水平之下,2012年化学农药的使用量较2011年减少15.4%,保护了烟田生态环境,提升了烟田自然因子的控害能力,实现了示范区病虫害的可持续控制。

Application of Green Plant Protection Technology in Gaoligongshan Green Ecological Quality Tobacco Production

In Gaoligongshan green ecological high quality tobacco production demonstration areas, green plant protection technology system has been built. The construction principles of the system are that as a basis for agricultural control, to focus on biological control, physical control for the auxiliary and as a supplement to chemical control. The core technologies of the system is composed of yellow card to trape Myzus persicae and Bemisia tabaci, frequency vibration-killing lamp to control tobacco pests, sex pheromone to trape Prodenia litura, Heliothis assulta and Helicoverpa armigera, the Aphidius gifuensis to contrnl Myzus persicae, biological agents to control tobacco pests and diseases. The demonstration and extension results showed that the losses of the pests and diseases infestation has been controlled under the permissible economy level, the use of chemical pesticides reduced the amount of 15.4% in 2012 compared with that of the 2011. Through the application of green plant protection technology, the ecological environment of tobacco fields has been protected, the natural factom controlling pests and diseases ability been enhanced, and the sustainable pest and disease control achieved.
