摘要
通过70年的治理,榆林沙区生态环境得到进一步改善。随着飞播灌木造林地植被盖度的持续增加,近年来,各种植物病虫害危害也呈现增加的趋势。针对出现的病虫害严重的问题,选择不同区域对危害程度较为严重治沙先锋植物进行害虫调查,结果表明,沙蒿木蠹蛾对沙蒿的危害是榆林沙区飞播灌木林最主要害虫之一,并依据其生活习性和发生特点,有针对性的采取生物措施、物理措施和化学措施等综合防治,达到了预期的防治效果。
After 70 years of management,the ecological environment of Yulin sandy area has been further improved,and the vegetation coverage of aerial seeding shrub forestation land has continued to increase.Various plant diseases and insect pests,however,have also shown an increasing trend.In view of the serious problems of diseases and insect pests,different regions were selected to conduct pest investigation into the pioneer plants.The results showed that the damage of Holcocerus artemisiae to Artemisia arenaria was one of the most important pests in the aerial shrub forest in Yulin sandy area.According to its living habits and occurrence characteristics,biological,physical and chemical measures were taken to control the pests.
