以杨树溃疡病发病资料和气象数据为基础,对杨树溃疡病与气象因子的关系进行了分析,筛选、确定了肇源县影响杨树溃疡病的主要气象因子,分别为5月极端低温(x10)、6月平均湿度(x13)和8月降水量(x23),建立的回归模型预测精度达90%以上,达到了利用该模型对杨树溃疡病预测的基本要求。
Based on the data of poplar canker disease and meteorological data, the relationship between poplar canker ulcer disease and meteorological factors was analyzed, and the main meteorological factors affecting poplar canker disease were identified and identified as the extreme low temperature in May (x10), average humidity in June (x13) and precipitation in August (x23). The prediction accuracy of the regression model was over 90%, which met the basic requirements for prediction of poplar canker disease using this model.
