摘要
为了验证CARAH预警模型在青海马铃薯晚疫病测报上的适用性,本研究以青海省互助县台子乡为例,对该地区7—8月份的气象数据与田间晚疫病的发生情况进行了综合分析。测报结果表明:在马铃薯生育期内,晚疫病共发生了2代、完成了3次侵入,与田间调查结果基本吻合。同时,利用测报结果对病害进行了防治,实践证明CARAH预警模型对当地晚疫病的测报具有指导性,可在生产中推广应用。
To verify the applicability of CARAH warning model on the potato late blight forecasting, taking the potato planting area of Taizi Township, Huzhu County, Qinghai Province as an example, the relationship between the meteorological data of the area from July to August and field occurrence of late blight was explored. The predicted the occurrence of late blights was 3 infections and 2 gener-ations during the growth period, which was consistent with the field investigation. At the same time, this warning result was used to instruct disease control, and the practice proved that CARAH warn-ing model can be applied in the local potato production.
