摘要
对山西省太谷县枣区枣黑顶病发生程度与大气氟含量及6个气象因子的关系进行逐步回归分析,结果从中筛选出大气氟浓度、平均温度、相对湿度、日照时数4个关键因子,且大气氟含量、相对湿度与枣黑顶病的发病率呈极显著正相关,平均温度、日照时数与枣黑顶病的发病率呈极显著负相关。
Based on the data collected from the jujube growth area of Taigu County, Shanxi Province, the analysis of the relationship between the incidence of the jujube black top disease and six meteorological factors along with the atmospheric fluoride concentration was conducted. Four key factors, the atmospheric fluoride concentration, average temperature, relative humidity, and sunshine duration were chosen out in the paper. It draws the conclusion that there is a significant positive correlation between the atmospheric fluoride concentration, relative humidity and the incidence of the disease whereas the average temperature and sun- shine time have remarkable negative correlation with it.
