摘要:
研究了停止割脂、封山育林、抚育管理、降低油松在林分中的比率4种营林技术措施对控制红脂大小蠹危害的影响。结果表明，停止割脂后第3年有虫株率下降42.72%、株均虫口减少49.37%，封山育林后第3年有虫株率下降78.68%、株均虫口减少54.89%，抚育措施对该虫的危害影响较小；混交林与纯林比较，当油松在林分结构中的比例低于40%时，第3年有虫株率下降5.91%～26.27%、株均虫口平均减少6.44%～34.62%。第2期李有忠等营林技术措施对红脂大小蠹控制效果研究
Abstract:
Control effect on Dendroctonus valens was studied by adopting 4 kinds of forest management measures including stopping turpentine, closing hillsides to facilitate afforestation, fostering tending of woods and decreasing the percentage of pine in forest stand. The results showed that the percentage of insectinfected trees at the third year after stopping turpentine descended 42.72%, the insect population per tree decreased 49.37%. The percentage of insectinfected trees at the third year after closing hillsides to facilitate afforestation descended 78.68%, the insect population per tree decrease 54.89%. The control effect of fostering tending of woods to this insect is not prominence; if mixed forest and pure forest are compared, when the percentage of pine in forest was lower than 40%, the percentage of insectinfected trees at the third year decreased by 5.91%26.27%, the average insect population per tree decreased by 6.44%34.62%.
