摘要
雪霉雪腐病是新疆维吾尔自治区昌吉回族自治州冬小麦的主要病害,每年都有不同程度发生,随着气象条件的变化形成了发病周期。通过搜集1996—2018年病害资料与田间调查,分析冬小麦雪霉雪腐病发病率与冬季最大积雪深度、≥20 cm积雪日数、≥30 cm积雪日数、3月中旬降水量、3月下旬平均气温等19个气象因子的相关性,筛选出强相关性气象因子,建立了冬小麦雪霉雪腐病发生气象等级预报模型,通过应用检验,有比较好的预报效果。
Snow mold was the main diseases of winter wheat in Changji Hui Autonomous Prefecture,Xinjiang Uygur Autonomous Re?gion,they occur every year to varying degrees,and they form an onset cycle with changes in weather conditions.By collecting disease data from 1996 to 2018 and field surveys,the correlation between winter wheat snow mold incidence and 19 meteorological factors such as maximum snow depth in winter,≥20 cm snow days,≥30 cm snow days,precipitation in mid-March,average temperature in late-March were analyzed.The strong correlation meteorological factors was screened out,and a meteorological grade forecasting model for winter wheat snow mold rot was established.The application test has a good forecasting effect.
