摘要
运用通径分析的原理 ,对 1 988～ 1 989年在尤溪设立的 8个标准地所收集的气象因子和病速的观察资料进行研究 ,力图剖析各因子对毛竹枯梢病发生发展的影响程度及其因子间的相互关系 .结果表明 :平均气温与病速是决定毛竹枯梢病病情指数的主导因子 ,平均相对湿度对毛竹枯梢病病情指数的直接作用不大 。
Based on the data obtained of the Top Blight of P heterocycle, the influencing grade to disease index of Top Blight of P heterocycle of pathogens temperature, relative humidity, rainfall and increase speed of disease index were studied by the means of path analysis method The result showed that pathogens temperature and increase speed of disease index were main factors deciding disease index of Top Blight of P heterocycle, the direct influence of relative humidity were not great while its indirect influence by other factor were great
