以优质高产晚熟新品系龙辐９１Ｂ５６９为材料，研究了小麦抽穗期喷药、施肥对小麦产量的影响。结果表明各处理方法对小麦白粉病的反应型不同，多菌灵、多菌灵＋福美双、十三吗啉＋ＫＨ２ＰＯ４对小麦的反应型为１级，说明喷施多菌灵、福美双、十三吗啉提高了对小麦白粉病的防治效果，延长功能叶片的光合作用，增加小麦籽粒的千粒重，以致提高了小麦的产量。
Longye 91B569, a new late-ripening line with high yield and good quality, was used to study the effect of spraying and fertilizing wheat on the yield of wheat at heading stage. The results showed that each treatment method had different responses to wheat powdery mildew. Carbendazim, carbendazim + thiram, tridemorph morpholine + KH2PO4 had a level 1 response to wheat, indicating that spraying carbendazim, thiram, Trimorpholine improves the control effect on wheat powdery mildew, prolongs the photosynthesis of functional leaves, increases the 1000-grain weight of wheat grains, and increases the yield of wheat.
