| 摘 要： | １９９４年和１９９５年在玉溪市北城镇刺桐关办事处石狗头村，云南松纵坑切梢小蠹虫危害的云南松林中，进行了施肥试验。施肥后的云南松被害株率和蠹害指数平均下降２２．６９％和３３．７％，而未施肥的云南松被害株率和蠹害指数平均下降１１．７３％和１８．３％，被害株率和蠹害指数实际平均下降１０．９６％和１５．４％。试验证明，通过施肥，增强树势，能提高云南松对纵坑切梢小蠹虫危害的抵御能力，起到间接防虫的效果

| Abstract: | The fertilization test on the trees damaged by Tomicuspiniperda has been done in the forest of Pinus yunnanensis in 1994 and 1995 in Shigoutou village, Citongguan office,Beicheng town of Yuxi city.The results showed that on the average, damaged rate and the damaged index of the trees decreased by 22.69% and 33.7% respectively after fertilized,those of unfertilized Pinus yunnanensis forest decreased by11.73% and 18.3% respectively.actually the 2 data decreased by 10.96%and 15.4% respectively,also the results of test indicated that it is possible to increase the resistance ability of Pinus yunnanensis to Tomicus piniperda through fertilization and strengthening the power of Pinus yunnanensis. |
