摘要：

研究结果表明,甘肃陇南越夏区条锈菌源的主要传播路线是沿康县至略阳的近正西气流轨道和文县至广元的西北气流轨道,主要对汉中地区和绵阳的大多数地区小麦秋苗吹送,并可波及陕西安康地区和商洛部分地区及四川达县和万县等地。四川阿坝州越夏区菌源的主要传播路线是沿汶川至灌县的西北偏北气流轨道。其菌源与成都平原麦区的关系密切,对绵阳地区的北川、平武和绵竹等地也很重要,并可波及南充、内江及江汉流域等地区。湖北秋苗的初始菌源多来自西北越夏区。

摘要：

Longnan prefecture of Gansu province and Abazhou of Sichuan provi-nce,where stripe rust of wheat caused by Puccinia striiformis often occursfrequently,are importan toversummering areas of wheat stripe rust in China.Field surveys and tests on the dispersal of wheat stripe rust were carried out inLnognan and Aba District during 1979—1984.In the major dispersal trackof ov- ??ersummering inoculum of stripe rust in Longnan,there are two pathways,i.e.nearwestward trajectory of airflow from Kang county to Lueyang countyand southwestward trajectory of airflow from Wen county to Guangyuancounty.The oversummering inoculum in this area is mainly blown by windtoward the autumn-sown wheat seedlings in Hanzhong and major parts ofMianyang prefectures,and also can be spread to Ankang and part of Shangluoprefectures in Shanxi province,Da county and Wan county in Sichuan prov-ince ect.The major dispersal track of oversummering inoculum in Abazhouof Sichuan province is along northwestward by northward trajectory ofairflow from Wenchuan county to Guan county.Inoculum within this areahas in close conne ction with wheat region in Chengdu plain and also is animportant source of inoculum for autumn-sown wheat seedlings in Beichuan,Pingwu and Mianzhu counties of Mianyang prefecture.And it can be spreadto Neijiang,Nanchong prefectures and Jianghan river basin and so on.Theinitial inoculum sources of stripe rust at autumn-sown wheat seedlings inHubei province most likely come from northwestern oversummering area.So,it is very important to control the stripe rust of wheat in Longnan andAba oversummering area.
