摘　　要：【目的】调查核桃小麦间作田、红枣小麦间作田及小麦单作田小麦白粉病发生情况,研究果树小麦间作模式下小麦白粉病发生为害情况与小麦单作田的差异性。【方法】采用定期定点调查的方法,研究核桃小麦间作田、红枣小麦间作田和小麦单作田小麦白粉病的田间消长规律。【结果】小麦白粉病在5月中旬开始为害,核桃小麦间作田和红枣小麦间作田小麦白粉病田间消长规律与小麦单作田基本一致。小麦白粉病病情指数:核桃小麦间作田>红枣小麦间作田>小麦单作田。【结论】果树小麦间作田和小麦单作田小麦白粉病田间消长规律基本一致,但果树小麦间作田小麦白粉病病情指数高于小麦单作田。【Objective】o investigate the fruit wheat intercropping difference of monoculture field with wheat powdery mildew damage mode through the investigation of the wheat powdery mildew occurrence of the walnut-wheat intercropping,jujube-wheat intercropping and wheat monoculture fields.【Method】By regular fixed-point investigation method,the severity of wheat powdery mildew of walnut-wheat intercropping and jujube-wheat intercropping and wheat monoculture were investigated.【Result】Results showed that wheat powdery mildew began to harm in the middle of May,the growth and decline of wheat powdery mildew of fruit tree-wheat intercropping and wheat monoculture were basically consistent. The disease index of wheat powdery mildew was： walnut-wheat intercropping 〉jujube-wheat intercropping〉 wheat monoculture.【Conclusion】The growth and decline of wheat powdery mildew of fruit tree-wheat intercropping and wheat monoculture was basically consistent. The disease index of wheat powdery mildew of fruit tree-wheat intercropping was higher than that of the wheat monoculture.
