| 摘 要： | 2011年通过田间病情消长调查,应用比利时马铃薯晚疫病预警系统分析了固原市马铃薯晚疫病发生程度与各环境因子的关系。结果表明,马铃薯晚疫病始见期迟早与发生程度无正相关关系,高湿有利于发病,但高温可抑制发病。利用比利时马铃薯晚疫病预警系统预测的结果与大田发生蔓延情况基本吻合。

| Abstract: | Belgium CARAH model was used to analyze effects of environmental factors on degree of potato late bright through investigation in fields in 2011.The results showed that the earliest disease plant was not related to degree of potato late bright.The moist environment may be beneficial to disease plant,but may suppress potato late bright at the same time.Belgium CARAH model for forecasting potato late blight was consistent to the breakout degree of potato late bright in fields. |
