摘　　要：连续2年选择西昌葡萄种植相对比较集中的西宁镇、西乡乡、川兴镇以及礼州镇,使用五点法调查葡萄在露地栽培、避雨栽培、大棚栽培3种不同栽培条件下葡萄白粉病的发病情况。结果表明,露地栽培通风透光性好,能够有效控制白粉病的发生;避雨栽培可以达到避雨效果,但棚内局部温度高,易形成干旱条件,白粉病病害较严重;大棚栽培棚内环境高温、高湿,白粉病病害相对较轻。In order to study the incidence of grape powdery mildew under different cultivation conditions,such as open cultivation,rainproof cultivation and greenhouse cultivation,the investigation was done by 5 points method for two years,four towns were chosen including Xining Town,Xixiang Town,Chuanxing Town and Lizhou Town,in which grape planting was relatively concentrated.The results showed that it could effectively control the occurrence of powdery mildew on the condition of the open cultivation,where ventilation and light transmittance were better.Rainproof cultivation was a good shelter,but it was easy to form dry conditions because of high local temperature in the shelter,so that powdery mildew was serious.Powdery mildew was relatively light under greenhouse cultivation because of relative environment with high temperature and high humidity.
