【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】 The objective of this study was to investigate the occurrence of field wheat and wheat single cropping wheat powdery mildew in the intercropping of wheat and wheat, and to study the difference of the occurrence of wheat powdery mildew and the single cropping of wheat under the intercropping of wheat and wheat. 【Method】 The regular field survey method was used to study the field growth and decline of walnut wheat with intercropped wheat and wheat with intercropped wheat and wheat. 【Result】 Wheat powdery mildew began to damaging in mid-May. The field growth and decline pattern of wheat and wheat intercropped with wheat and wheat with inter-crop of wheat and wheat with interplanting of wheat and wheat was basically the same as that of monoculture with wheat. Wheat powdery mildew Disease index: Walnut wheat intercropping> jujube wheat intercropping> wheat monoculture. 【Conclusion】 The results showed that the law of field growth and decline was basically the same between the intercropping wheat and wheat single cropping field. The disease index of wheat and wheat intercropping wheat field was higher than that of single cropping of wheat.
