对江陵稻区22 年的气象数据逐旬建立变量, 利用逐步回归分析筛选出了与白叶枯病病情指数相关较密切的变量, 建立了预测当地白叶枯病发生程度的多元回归方程。
Based on the 22-year meteorological data of Jiangling rice area, variables were set up ten days later, and the variables closely related to the disease index of the bacterial blight were screened out by stepwise regression analysis. The multiple regression equation for predicting the occurrence degree of the bacterial blight was established.
