摘　　要：以冬小麦品种豫麦 34为材料 ,在不同带距条件下对小麦籽粒产量、蛋白质含量和蛋白质产量以及三者相互关系进行了研究。结果表明 :带距对蛋白质产量和籽粒产量有显著的影响 ,对籽粒蛋白质含量影响不明显 ;蛋白质产量与籽粒产量呈现极显著正相关 ,与籽粒蛋白质含量关系不密切 ;蛋白质产量与籽粒产量之间存在着直线回归关系 ,二者的模拟方程为 :Y =10 6 80 9+0 10 7X(kg·hm-2 ) ;2 0m带距条件下小麦籽粒产量最高 ;2 4米带距条件下 ,小麦边行优势总值最大 ,与其它作物套作 ,效益较好。The grain yield(GY), protein content(PC), and protein yield(PY) of winter wheat in different bands spacing, and their relationships between each other were studied with winter wheat varity of Yumai 34. The results showed that band spacing took hadlsingificant effect on the wheat PY and GY, but no effect on the PC; PY had significant relationship with GY, and no close relationship with PC.Linear regression relationship exists between PY(Y) and GY(X):Y=106 809+0 107X(kg·hm -2 ); GY was the highest at 2 0m band spacing,The marginal effect was the greatest and better benefit will be gotten with relaying intercropping in 2\^4m band spacing.
