根据勃利县林业局通天一林场种子园1986～1991年的气象资料，对5、6月的日最高气温与日最低气温的温差和日最大风力的日数进行概率分析。结果表明，我国引发落叶松枯梢病发生的环境条件与日本不同，温差和风力是引发该病的主要诱因。
According to the meteorological data from 1986 to 1991 in Tong Tianyi Forestry Farm of Boli County Forestry Bureau, the probabilities of the daily maximum temperature and daily minimum temperature and the maximum daily maximum winds in May and June were analyzed. The results showed that the environmental conditions that caused the Larix principis-rupprechtii disease in our country were different from those in Japan. Temperature difference and wind force were the main inducing factors.
