摘要[ 目的] 为樱花褐斑穿孔病的防治提供理论依据。[ 方法] 对气象资料进行分析, 统计樱花叶片孔洞数, 研究空气湿度对樱花褐斑
穿孔病的影响。[ 结果] 当气温为20 ~30 ℃时, 湿度是决定樱花褐斑穿孔病发病程度的主要因素, 发病程度与空气湿度呈显著正相关。
[ 结论] 空气湿度与樱花褐斑穿孔病的发生密切相关。

Abstract [ Objective] The research ai med to provide theoretical basis for the control of sakura cercospora shot hole . [ Method] The meteorological data
of Shanghai was analyzed ,the number of holes onleaves of Prunus lannesi ana was counted ,and the i nfluence of humidity on sakura cercospora shot hole
was investigated .[ Result] Whenthe temperature was 20 - 30 ℃, humidity was the mai nfactors determing the degree of sakura cercospora shot hole ,and
there was a positive correlation between them.[ Concl usion] Humidity was closely related to the happening of sakura cercospora shot hole .
