Abstract: 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 PYand GY, but no effect on the PC; PYhad 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穐m-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.
