中文摘要:

为了明确陕西省小麦条锈菌越夏范围，通过多年调查和试验研究，结合近年来各地小麦播种面积变化情况，对陕西省条锈菌越夏范围进行了系统分析。结果表明，小麦条锈菌在陕西省能够顺利完成越夏。越夏区主要分布于陇县、太白、凤县等高海拔地区；不稳定越夏区主要分布于镇安、旬阳阳山等海拔1 400 m以上小麦种植区；留坝、宁强、山阳、周至和宁陕等海拔1 400 m以上区域几乎没有小麦种植，已丧失了越夏区作用，成为小麦条锈菌非越夏区。

英文摘要:

Making clear of over summering of Puccinia striiformis f. sp. tritici (Pst) in Shaanxi province has great importance for forecasting and integrated control of wheat strip rust. Through organized survey and experiments in the over summering regions, we studied systematically the situation of over summering of Pst in Shaanxi province. The results showed that Pst could over summer in some local regions in Shaanxi province. Altitude above 1 400 m in Longxian, Fengxian, Taibai county and the Yangshan mountains in Zhen′an and Xunyang county were the main regions for Pst over summering. The mountains in Zhen′an and Xunyang belonged to unstable over summering regions and the wheat planting area was about 2 000 hm in 2010. There was almost no wheat cultivation in Liuba, Ningqiang, Shanyang counties where altitude were above 1400 m, so these regions had no function for over summering of Pst.
