甘肃太子山林区落叶松鞘蛾防治与研究

Control and Research on Larch Sheath Moth in Taizishan Forest Area of Gansu Province

从20世纪70年代末至今,甘肃太子山林区大面积种植华北落叶松,已使华北落叶松成为太子山林区的特色乡土树种,大批优秀树种在太子山林区生长旺盛,华北落叶造林工程大有成效。与此同时,太子山林区的落叶松鞘蛾活跃的现状也为林区的病虫害防治工作埋下了巨大的隐患,太子山林区的病虫害防治存在诸多问题,早期忽视对苗木种子的检疫,导致落叶松鞘蛾大面积蔓延,已经严重影响太子山林区落叶松林木的生长情况。根据太子山林区的落叶松林区分布和落叶松鞘蛾防治的情况,详细介绍了化学、物理、生物、营林防治措施,旨在为当地病虫害防治提供切实可行的防治路径。

Since the end of the 1970s,larch has been widely planted in Taizi Mountain forest area of Gansu province,which has made larch become the characteristic local tree species in Taizi Mountain forest area.A large number of excellent tree species grew vigorously in Taizi Mountain forest area,and the deciduous afforestation project in North China has achieved great results.Taizi mountains area,meanwhile,the status quo of larch sheath moth active for forest insect pest prevention also buried the huge hidden trouble,the pest control had many problems of taizi mountains area,early neglect on seedling seed quarantine,thousands of larch sheath moth spread,had the serious influence taizi mountains forest larch forest growth.According to the distribution of larch forest area and the control situation of larch sheathing moth in Taizi Mountain forest area,the chemical,physical,biological and forest control measures were introduced in detail in order to provide feasible control path for local pest and disease control.
