甘肃河东地区小麦条锈病(Wheat Stripe Rust)越夏指标的修订
|
摘要
小麦条锈病越夏气象指标,目前仍沿用二十世纪六十年代的研究结果,需要修订完善。文中利用甘肃河东地区2007-2014年50个不同海拔高度小麦条锈病单点病田率、病情指数调查资料、39个平均越夏病田率资料,采用统计学方法建立了小麦条锈病病情指数、平均病田率的气象统计模型,综合两种方法计算结果,确定了甘肃河东地区小麦条锈病越夏指标的上限为夏季最热时段8d滑动平均气温24~25℃,期间空气相对湿度越低对应的平均气温也越低。研究为当地准确发布中短期趋势预报,积极开展早期防治,控制病害越夏范围具有一定指导意义。
The summer meteorological indicators of wheat stripe rust that are now still used are the research results of 1960's,and need to be revised and improved.Based on the investigations of wheat stripe rust disease rates including 50 single points at different altitudes,disease index survey data,and 39 average through summer disease rates at the area of eastern Gansu from 2007 to 2014,we applied statistical method to establish the meteorological models of wheat stripe rust disease index and average disease field rate,and then determined the maximum limit for wheat stripe rust,that is the 8 day temperature slide during the hottest period of summer is 24 ~25℃.During the period the lower relative humidity corresponds to the lower air temperature.The study results have a certain significance for the accurate short-term forecast for local field management.
