通过对发生区内松林进行间伐、修枝等营林措施将松林的郁闭度调整至0.5左右。试区试验结果松突圆蚧的虫口密度从采用营林措施前的2.61头/束下降至0.63头/束,虫口密度下降75.86%,在城市公园规划设计上还应考虑位于不同的坡向营造不同的树种,以防止松突圆蚧的发生和危害。
By adjusting the pine forests in the area, silvicultural measures such as thinning and pruning were adopted to adjust the canopy density to about 0.5. Test results of the pilot area scale population of Populus tomentosa population densities from 2.61 before the use of forest measures / bunch to 0.63 head / bundle, population density decreased 75.86%, in the urban park planning and design should also be considered in different slope to create Different tree species, in order to prevent the occurrence of pine scales scale and harm.
