| Abstract: | The correlation between rape white rust and meteorological factors in Lhasa from 1988 to 1990 were analyzed. The main results are as follows:The conditions favorable to the occurrence and development of rape white rust are higher mean temperature higher night mean temperature, less diurnal range of temperature, more rainy days and less radiation, higher relative humidity. Raise the ground temeprature can reduce the occurrence and development of rape white rust. |
