以满播小麦为对照，研究了不同规格麦棉套种小麦的边行优势效应以及预留行宽度与边行优势效应的关系。结果表明：麦棉不同规格套种对小麦单产有一定的边行优势效应；其边行效应主要反映在单位面积成穗数方面，而对小麦的穗粒数和千粒重无明显影响；小麦边行优势效应的大小，在一定范围内只与每带小麦边行所占比例有关，与预留行宽窄无关。
Taking full-sowing wheat as a control, we studied the superiority of side-rows and the relationship between the width of reserved rows and the superiority of side-rowing wheat with different specifications of wheat and wheat intercropping. The results showed that different wheat and cotton interplanting had certain sideline superiority effect on wheat yield. The sideline effect was mainly reflected in spikelets per unit area, but had no significant effect on the number of spikelets per panicle and 1000-grain weight. The effect of the size, within a certain range only with the proportion of each side of the wheat with the proportion of lines, with the reserved line width has nothing to do.
