摘要
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。
Using 91B569 a new line of wheat as material,the effects of spraying pesticide and applying fertilizer on wheat yield was studied.The results showed that different treatments resulted in difference of resistance to wheat powdery mildew. In the treatments of carbendazim,carbendazim+thiram and tridemorph+KH 2PO 4,the resistance to powdery mildew was the first grade.Spraying carbendazim,thiram and tridemorph improved the prevent effection of wheat powdery mildew,extended photosynthesis of functional leaves,raised weight of 1000 kernels, and therefore increased wheat yield.
