摘要
根据2000年、2001年和2003年5-10月田间试验和相应的气象观测资料,利用相关普查和回归分析方法分析了果实形成期枸杞黑果病与气象因子的关系。结果表明,枸杞黑果病病情指数与果实形成期的降水量、降水日数、平均相对湿度、平均日照时数和平均风速间均具有极显著相关关系。其中降水量、降水日数和平均相对湿度是枸杞黑果病暴发流行的主要原因。
Based on the experimental and meteorological data in Yinchuan, Ningxia Hui Autonomous Region, the relationship between meteorological factors and occurrences of Colletotnchum gloeosprioides penz of Lycium barbarum was studied by correlation and regression analysis. The result showed that meteorological factors were highly related to the occurrences of Colletotnchum gloeosprioides penz of Lycium barbarum. The main meteorological factors included rainfall, rainy day, mean relative humidity, mean sunshine duration and mean breeze during fruit developing stage of Lycium barbarum. The rainfall, rain-days and mean relative humidity were more important than others.
