摘　　要：在田间条件下研究加工番茄不同品种、不同播种时间、不同栽培管理方式以及气象因子对早疫病发生的影响。结果表明:新疆种植的加工番茄品种多不抗病,是加工番茄早疫病发生的主要因素;4月25日播种和5月10日育苗移栽,加工番茄早疫病发生最为严重,病情指数分别达到88.33和76.66;在5月9日同期栽培条件下,育苗移栽加工番茄早疫病发生严重度均高于直接播种的栽培方式,其中覆膜栽培膜上覆盖麦草的栽培模式早疫病发生最为严重,病情指数达到45;5月份日平均温度越高,6月份降雨量越多,早疫病发生越严重。The study was to research the influence of different processing tomato varieties,different seeding time,different plant pattern and meteorological factor to processing tomato early blight diseasing under field.The results showed that the principal reason of processing tomato early blight seriously occurring were most processing tomato varieties were susceptible and highly susceptible.When seed sowed in April 25 and seedling transplanting in May 10,processing tomato early blight seriously occurring and the disease index were 88.33 and 76.66 respectively.When seed sowing and seedling transplanting were planted in May 9,different seedling transplanting treatment had highly disease index than different seed sowing treatment respectively and all treatment mulching methods increase the disease index than natural planting.The method that plastic film covered then covered with straw had highest diseased,the disease index were 45.The higher daily average temperature in May and higher rainfall had caused processing tomato early blight seriously occurring.
