作者经过20多年的试验确定了呼和浩特地区马铃薯晚疫病短期和长期预测方法。短期预测试验中在吸收了前人工作成果的同时,定期定时地观察了信号地、宅旁院地和育种试验地,长期预测的方程为y=31.4E-71.2。采用以上方法准确地预测了呼和浩特地区马铃薯晚疫病的发生。 After more than 20 years of experiments, the authors determined short-term and long-term prediction methods of potato late blight in Hohhot. In the short-term prediction test, while taking the previous work out, we regularly observed the signal ground, house yard and breeding trial site. The long-term prediction equation is y = 31.4E-71.2. Using the above method to accurately predict the occurrence of potato late blight in Hohhot.
