昆嵛山赤松纯林赤枯病特征及与林分因子的关系

解析和定量评价了林分因子对赤松赤枯病发生（发病率和病情指数）的影响，研究发现松赤枯病的发病率和病情指数在不同林分因子分组中均有差异，且受林分密度和枝下高的影响最显著，并提出病害防治建议：对昆嵛山区域赤松纯林赤枯病的防治工作要以林分密度和枝下高为主要调控对象。

The effects of stand factors on the occurrence of Pinus densiflora needle blight, with incidence rate and disease index as the evaluation indicators, were analyzed and quantitatively evaluated. The study found that the incidence rate and disease index of pine needle blight varied among groups stratified by different stand factors, and were most significantly affected by stand density and clear bole height. Moreover, disease control recommendations were proposed: for the prevention and control of Pinus densiflora needle blight in pure Pinus densiflora stands in the Kunyu Mountain area, stand density and clear bole height should be taken as the main regulatory targets.
