研究杨树烂皮病发生发展与气象条件的相关关系,可为杨树烂皮病预报、防治提供科学依据。基于2002—2008年黑龙江省14个代表站点杨树烂皮病资料和气象资料,利用相关分析法,研究杨树烂皮病发生发展与气象条件的关系。结果表明：黑龙江省杨树烂皮病发病率与上年10月至当年4月平均气温、5—9月温湿系数、降水量、降水日数、上年10月和当年3月空气相对湿度、极端最高气温、气温日较差、气温日较差大的天气条件持续时间及平均风速呈正比,与上年10月至当年4月温湿系数、5—9月平均气温、上年12月至当年1月空气相对湿度、极端最低气温及日照时数呈反比。湿润、温凉和冬季冷热骤变的气候环境可以加剧杨树烂皮病的发生发展,日照充足和夏季高温对杨树烂皮病有抑制作用。

The relationships between Valsa sordida nits and meteorological conditions were analyzed in order to provide the scientific references for forecasting and controlling the disease.Based on the observational data of Valsa sordida nits and the meteorological data at 14 representative stations from 2002 to 2008,their relationships were discussed by a correlation analysis method.The results indicate that the incidence rates of Valsa sordida nits is in a positive correlation with some meteorological conditions such as air temperature during October of previous year to April of current year,the temperature-humidity coefficient from May to September,precipitation,the number of precipitation days,the relative humidity from October of previous year to March of current year,the extreme maximum temperature,the diurnal temperature range(DTR),duration of large DTR and the mean wind speed,while it is in a negative correlation with the temperature-humidity coefficient during October of previous year to April of current year,the mean temperature from May to September,the relative humidity from December of previous year to January of current year,the extreme minimum temperature and sunshine duration.Some climatic conditions such as humidity,warming,cold and the sudden change of cold and warm in winter could strengthen the occurrence and development of Valsa sordida nits,while some others such as abundance sunshine and high summer temperature could restrain the disease.
