CARAH模型预测不同海拔马铃薯晚疫病中心病株出现时间观察

Observation of the occurring time of center disease plants of potato late blight at different altitudes and its prediction with CARAH model

通过2014、2015年2年在贵州省6个不同海拔高度马铃薯主产县试验观察,6个马铃薯基地观测圃费乌瑞它中心病株出现时间与CARAH模型预测值吻合,表明CARAH模型对费乌瑞它马铃薯晚疫病中心病株出现时间有较为准确的预测作用。

Observation of occurring time of center disease plant of potato late blight on variety ＂Fei Wurui it＂ potato in 6 main potato producing counties at different altitudes were conducted in 2014 and 2015, and comparing experiments were executed between field observation and prediction with CARAH model. The two results coincided with each other which indicated that it was a relatively accurate method of prediction for center disease plant of ＂Fei Wurui it＂ potato with CARAH model.
