【摘要】 [目的]调查营林措施对杨扇舟蛾和杨树水泡溃疡病的防治效果。[方法]通过轻度、中度、重度间伐和修枝进行杨扇舟蛾和杨树水泡溃疡病的防治试验。[结果]杨扇舟蛾的防治以中度间伐为宜,虫口密度平均下降10.83%;杨树水泡溃疡病的防治,以轻度间伐最佳;修枝对杨扇舟蛾和杨树水泡溃疡病的防治均以中度为宜。[结论]间伐和修枝有利于杨树病虫害的防治。更多还原

【Abstract】 [Objective] The aim was to investigate the control effects of forest management measures on Clostera anachoreta and Botryosphaeria dothidea.[Method] The control effects of mild,moderate,severe thinning or pruning on the C.anachoreta and B.dothidea were tested.[Result] The results showed that moderate thinning was appropriate to control C.anachoreta,and the average insect population density decreased by 10.83%.And mild thinning was the best to control B.dothidea.The moderate pruning was suitable for controlling both C.anachoreta and B.dothidea.[Conclusion] The forest management measures of pruning and thinning were beneficial to control poplar diseases and insect pests.更多还原
