| 摘 要： | 在福建省三明地区杉木设立了４８４块标准地，对杉木炭疽病的发病程度及标准地有关因子进行了调查和回归分析，发现杉木炭疽病的发病程度与林龄，立地类型和坡位间存在密切关系，与林份密度，海拔高度，土壤类型之间也有一定关系；而与土层厚度，抚育情况，坡向和混交比之间关系不密切，指出在实际生产中，只要在不在Ⅲ，Ⅳ类地和坡顶造林，即可有效地控制杉木炭疽病的发生。

| Abstract: | plots of Chinese fir in Sanming Prefecture of Fujian province were investigated and the correlation of disease index of anthracnose and 10 factors of plots were analysed. The 10 factors are (1)site class, (2)soil type, (3)soil depth, (4)tending, (5)position on the slope, (6)direction of hillside, (7)stand age, (8)stand composition, (9)stand density and (10)elevation. The results indicated that the disease index correlated significantly with (1), (5) and (7), correlated slightly with (2), (9) and (10), and had no relation to (3), (4), (6) and (8). It was concluted that the disease could be controled effectively, if there was not any planting of trees on the site of above 3 and the top of the hill. |
