摘　　要：麦棉两熟条件下，采用３－１式播种方式，对大穗、大粒型小麦品种９３中６（３７系）进行了３种不同行距栽培试验。结果表明，缩小行距有利于小麦、棉花产量的提高，３种行距间产量差异显著；随着行距的缩小，亩产量和有效穗数增加，千粒重和穗粒数减少，差异不显著。Under the rotation system of wheat cotton,the culture test with 3 kinds of different row spacing for big spike and big grain wheat variety 93 zhong 6 (37 line) sown by 3-1 sowing way shows that shortening row spacing is benefical to increase of wheat and cotton,there is significant difference in the yields form 3 kinds of row spacing,with the shortening of row spacing,the yield and the effective spikes increase ,while the 1 000 grain weight and spikes per row decrease,but the difference isn't significant.
