摘要
为明确新疆维吾尔自治区北疆马铃薯主产区真菌病害的种类及其发生特点,2014~2017年对马铃薯主产区真菌病害发生及流行情况进行调查,为开展关键有效的病害防治措施提供科学理论参考。调查表明,北疆有9种马铃薯真菌性病害,主要有早疫病、晚疫病、黑痣病、干腐病。病害的发生时间与严重程度取决于当地气候条件、品种特性和播期;主要病害因不同地区、年份、品种、栽培模式发生情况有差异;马铃薯黑痣病、黄萎病等土传病害日益严重,需引起足够重视。
Investigations on the occurrence and prevalence of fungous disease of potato in main potato production areas from 2014 to 2017 were conducted in order to clarify the fungous diseases and occurrence characteristics in main potato producing areas in northern Xinjiang Uygur Autonomous Region, so as to provide scientific and theoretical references for carrying out key and effective disease prevention measures. There were nine potato fungous diseases in northern Xinjiang, mainly including potato early blight, potato late blight, potato black scurf, and potato dry rot. The occurrence time and severity of the diseases were determined by local climate conditions, variety characteristics and the sowing time. The main diseases varied with different regions, years, varieties and cultivation patterns. The occurrence of soil-borne diseases,such as potato black scurf and Verticillium wilt, was increasingly serious, which should be paid enough attention.
