Abstract: The prevalent analysis of kiwifruit bacterial canker for several years showed that the effective ecological factors of severe degree were the precipitation (x1) in the second and last ten days of March,and the average temperature (x2) of January.The model was y=2.1359+0.0107x1-0.6061x2.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-13.254x2.The forecast effect of the equation was obviously significant after testing.
