摘　　要：对冀西北坝上地区饲用燕麦病害种类、主要害虫和天敌昆虫种类、主要杂草种类、发生频率、危害程度等进行研究。结果表明:燕麦田黑穗病最常见,炭疽病、秆锈病等受环境条件影响偶有发生,从危害程度看黑穗病中度危害,炭疽病、秆锈病轻度危害。饲用燕麦主要害虫种类有12种,蚜虫在8月中下旬受降雨影响,中度发生,危害部位主要集中叶片,叶鞘和穗子。以取食蚜虫为主的天敌种类有12种,有抑制蚜虫发生的趋势。田间杂草主要以狗尾草和灰绿藜为主。通过调查研究初步摸清了冀西北坝上地区饲用燕麦的病虫草害发生情况,为建立高标准燕麦干草生产基地提供技术指导。The objective of this paper was to investigate on the characteristics of disease types,pests and weeds in oat field in n northwestern bashang plateau of Hebei Province.The results showed that Ustilago avenae was the most common disease in oats field,and Colletotrichum graminicola and Puccinia graminis were occasionally affected via environmental conditions.Ustilago avenae was moderate in degree,but Colletotrichum graminicola and Puccinia graminis were slight in degree.There are 12 kinds of main insect pests in feed oats.Aphids are affected by rainfall in the middle and late August,and they occur in a moderate degree.The main damage parts are leaves,leaf sheaths and spikes.The weeds in the field were mainly Setaria viridis and chenopodium glaucum.The Investigation on the varieties of diseases and insects,and weeds in oat field in northwestern bashang plateau of Hebei Province provided technical guidance for the establishment of high standard oats hay production base.
