| 摘 要： | 通过两处不同营林抚育措施下星天牛(Anoplophora chinensi)对光皮桦(Betula luminifera)人工林分的危害调查,结果发现:造林前不炼山造林后不修枝、连续进行割草3年的营林抚育措施在一定程度上可以抑制星天牛对光皮桦幼树的危害。光皮桦纯林、光皮桦杉木(Cunninghamia lanceolata)混交林均易遭受星天牛的危害,且以冲沟地段受害较为严重;光皮桦幼树被星天牛危害后枯死率极高,2年生幼树受害后枯死率达100%,3年生幼树受害后枯死率达的达75%。

| Abstract: | According to the investigation on the harm of Anoplophora chinensis to plantation of Betula luminfera with tow different tending measures.The results showed that the measure which did not burn the mountain before afforestation and did not pruning after afforestation followed by mowing for 3 years continuously could inhibit the harm of Anoplophora chinensis to the Betula luminifera seedlings in a certain extent.Both the pure Betula luminifera afforestation and the afforestation with Betula luminifera mixing Cunninghamia lanceolata were easily suffered by Anoplophora chinensis,and it was more serious if they planted in gully area.After endangering by Anoplophora chinensis,the exsciccation rate of Betula luminifera seedlings was extremely high,which would reach 100% in the two-year seedlings and reach 75% in the tree-year seedlings. |
