| 摘 要： | 选定与林木生长和对杉木炭疽病病菌扩展有关的10个生态因子,在三明市的建宁、永安、尤溪3个县(市)设置标准地调查,通过计算和分析,发现林龄、立地类型、坡位、土壤类型、造林密度、海拔高度等6个因子与病害程度关系密切,其中与前5个因子呈正相关,与海拔高度呈负相关。混交比、土层厚度、抚育情况及坡向与病害程度关系不密切。在补充调查基础上,应用这一结果对福建省宁化国有林场部分杉木用材林进行了调整改造,并指导十五期间造林计划。

Main Factor Analyses of Colletotrichum gloeosporioides Occurrence and Their Application |
| |
| Abstract: | 10 ecological factors related with forest tree growth and Colletotrichum gloeosporioides germ spread are selected,the sample plots are set up to investigate in Jianning,Yong'an and Youxi 3 counties (cities)subordinate to Sanming City,through the calculations and analyses,this paper finds that 6 factors of forest age,site type,slope position,soil type,afforested density and altitude above sea level relate closely to the disease degree,which assumes the positive correlation with the first 5 ones among 6 factors,and assumes negative correlation with the last one.The mixed proportion,soil layer thickness,tending situation and aspect haven't close relationships with disease degree.On the basis of supplied investigation,part of Cunninghamia lanceolata timber stands of Ninghua National Forest Farm of Fujian Province are adjusted and improved with the results,which meanwhile guide the afforested plan during the 10th Five Year plan. |
