摘　　要：以大田棉花为对照(CK),研究了环塔里木盆地杏、棉间作系统对棉花的产量和纤维品质特性的影响。结果表明:杏、棉间作下棉花的产量及其构成因素相比对照均有不同程度的减小,且随着距杏树垂直距离的增加,其变化呈偏态分布趋势;在杏、棉间作区,棉花的比强度、伸长率和马克隆值明显减少,而纤维长度、整齐度、黄度和纺纱指数则形成了明显的增加区和降低区,表明杏、棉间作对棉花产量和纤维品质的影响很大。With the ingle cropping of cotton as CK, the effect of apricot-cotton intereropping on fiber quality characteristics and yield of cotton around Tarim Basin was studied. The results showed that the trend of changes in the yield and its components of cotton was in partial distribution tendency in the apricot-cotton intercropping system, which were lower than those in CK. In apricot-cotton intercropping, the strength, elongation and Micronaire value of cotton were cantly reduced, but the fiber length, uniformity, yellowness and CSP of cotton increased obviously in some areas but reduced in others. The experiment showed that the apricot-cotton intercropping had great effect on fiber quality and yield of cotton.
