摘  要:
在云南巧家县和东川区二二二林场华山松疱锈病发病高峰期,通过典型抽样调查,经数据处理后得出影响华山松疱锈病发生的主导林分因子,在巧家县为:林木长势、林内卫生状况、样地内松树密度、郁闭度;在东川二二二林场为:林木长势、坡位、郁闭度。两地病害发生的主导林分因子有一定的差异,为两地采用有针对性的林业技术防治措施、可持续控制病害提供了依据。

摘  要:
Through typical sampling technique, the relationship between forest factors and occurrence of Pinus armandii blister rust was studied in 222Forest Farm and Qiaojia County. It was found that the key forest factors in these two places are different. In 222Forest Farm, the key forest factors are the tending status of trees, slope position and sanitation conditions under trees, but that in Qiaojia County are the tending status of trees, the density of trees, sanitation conditions under trees and canopy density. The results provide some references for forest management and sustainable control of Pinus armandii blister rust.
