试验以徐州 2 5号为材料 ,研究了壮丰安和复合元素在小麦上的应用效果。结果发现 :处理后茎生 1～ 2叶叶面积减小 ,3～5叶叶面积增加 ,剑叶的增加幅度最大 ,同时叶片功能期延长 ;株高降低 ,茎秆充实度增强 ,花后干物质积累量增加 ,灌浆期延长 ,灌浆速度升高 ,从而粒重增加 ,产量提高 The experiment used Xuzhou No. 25 as a material to study the application effects of Zhuangfengan and composite elements on wheat. The results showed that after treatment, the area of ​​1 ~ 2 leaves decreased, the area of ​​3 ~ 5 leaves increased, the maximum increase of flag leaves and the prolonged function period of leaves. The plant height decreased and the stem filling degree increased. Material accumulation increased, grain filling period increased, grain filling rate increased, which increased grain weight and yield
