摘    要:对猕猴桃溃疡病流行分析表明,影响该病发生严重程度y的生态因子是3月中下旬降水x1和1月份均温x2,其模型是y=2.1359 0.0107x1-0.6061x2;猕猴桃溃疡病发生流行的主导因子为冬季及初春旬均温和降水量的相对变差,并且由此得到病害流行的回归方程为:y=-8.127 22.739x-13.254x^2,经检验,该方程达极显著水平。

关 键 词:猕猴桃溃疡病  病菌  流行预测  流行主导因子  相对变差  回归方程

Abstract:The prevalent analysis of kiwifruit bacterial canker for several years showed that the effective ecological factors of severe degree were the precipitation (x 1) in the second and last ten days of March,and the average temperature (x 2) of January.The model was y=2.1359 0.0107x 1-0.6061x 2.The main factor of the prevalence was the relative variation of ten days average temperature and precipitation in Winter and in early Spring,and the regression equation was y=-8.127 22.739x-13.254x 2.The forecast effect of the equation was obviously significant after testing.
Keywords:Kiwifruit bacterial canker  Pseudomonas syringae pv  actinidiae  Prevalent forecast  Main factor of forecast  Relative variation  Regression equation
