森林鼠兔害发生特点及防控措施

Study on the occurrence characteristics of forest pika disaster and its control measures of Mulan Forestry Administration

自20世纪70年代开始,木兰林区森林鼠兔害由零星发生转化为普遍发生,由危害新造林地幼树发展到危害落叶松、油松、樟子松、云杉幼林地及绿化大苗,影响造林绿化成效,降低绿化大苗经济效益。为防控鼠兔危害,主要采取了苹果切块拌磷化锌、小麦拌溴敌隆、苗干涂抹驱避剂、保护器投药饵等方法,有效地保护了造林成果,在实践中逐渐探索出一条技术先进、生产可行、经济上合算的防治技术措施。

Since the 70＇s of the last century, the Mulan Forestry Administration has witnessed the pika hazard occurrence in artificial larch and Pinus tabulaeforrnis forest in new plantation from sporadically into widespreadedly, which endangers both the development of newly planted saplings of Larix gmelinii , Pinus tabuliforrnis , Pinus sylvestris , Picea asperata plantation and greening seedlings, affecting the afforestation effect, reducing the economic benefits of greening seedlings. In the practice, effective prevention and treatments are conducted with the original apple cuts mixed with zinc phosphide, wheat mixed with bromadiolone, seedling trunks smeared with repellent, baits by dosing protector, indicating that there is a continuous progress in its prevention and control technology, and therefore the afforestation achievements have been effectively protected, and an advanced, well feasible, and economical prevention and control technology has been established.
