摘要:
根据安徽黄山市2008-2012年的气象资料和田间调查的病情,采用逐步回归和通径分析法,分析了气象因子与油菜根肿病发病率的关系。结果表明,9月份月均温、9月上旬降雨量和9月下旬降雨量与根肿病发病率关系最密切。建立了油菜根肿病的预测模型。

Abstract:
According to the meteorological data and field investigation of rape clubroot disease incidence during 2008-2012 in Huangshan city of Anhui province, the relationship between meteorological factors and rape clubroot disease incidence was analyzed by stepwise regression and path analysis. The result showed that important climate factors affecting the disease incidence of rape clubroot obviously were the average temperature, rainfall in first ten days and rainfall in the last ten days of September. A mathematical model for forecasting of disease epidemic was set up.
Key words:  rape clubroot disease  meteorological factor  stepwise regression  pathway analysis  forecasting of plant disease
