对河南襄城县１１ａ的气象因子与烟草黄瓜花叶病（ＣＭＶ）的病情指数关系进行分析，筛选出了影响病害发生的 １０个主要气象因子：１月上旬日相对湿度离均差，１月中下旬日相对湿度离均差，１月上旬日均温≥１０℃的积温，１月中旬水热系数，２月中旬温度离均差，３月上旬日相对湿度≤５０％的日数，３月上旬平均相对湿度，４月下旬日相对湿度离均差，４月份水热系数，５月上中旬相对湿度离均差．并建立了相应的回归方程，通过回测和试报检验，误差在亚１１％～２３％之间，表明依据以上气象因子可以对烟草ＣＭＶ进行中长期测报和短期测报．
The relationship between meteorological factors of 11a in Xiangcheng County of Henan Province and disease index of tobacco cucumber mosaic disease (CMV) was analyzed and 10 major meteorological factors influencing the occurrence of disease were screened out: the relative humidity was averaged from January to early January, The relative humidity in the second and second days from the average, the average daily temperature in early January ≥ 10 ℃ accumulated temperature, mid-January hydrothermal coefficient, the average temperature in February from the average, the relative humidity in early March day ≤ 50% of the number of days, March The average relative humidity in the first ten days of April relative humidity from the average, April hydrothermal coefficient, the relative humidity in mid-May from the average. The regression equation was established. The error was between 11% and 23% by backtesting and test reporting, which indicated that long-term and short-term measurement of tobacco CMV could be carried out based on the above meteorological factors.
