摘　　要：【目的】探明扁桃棉花间作对棉花品质的影响。【方法】以大田棉花为对照(CK),与22年生扁桃树下间作棉花品质进行比较研究。【结果】扁棉间作降低了树冠附近棉花的品质,棉花的棉纤维长度、整齐度、强度、伸长率、可纺系数和成熟度指数6个指标CK>树冠外侧2 m处>垂直树冠处>树冠内侧第一行,距离树干越近,棉花各指标数值越小;棉花短绒指数和马克隆值2个指标CK<树冠外侧2 m处<垂直树冠处<树冠内侧第一行,距离树干越近,数值越大。【结论】扁桃棉花间作系统中扁桃树冠对棉花品质影响显著,距离树干越近,影响越大,测试的8个指标中扁棉间作对棉纤维长度、纤维强度和马克隆值的影响最为显著。【Objective】To investigate the effect of almond and cotton intercroppingquality on the quality of cotton .【Method】Using field cotton as CK,the quality of the cotton intercropped under the 22-year old almond tree was compared and analyzed.【Result】Almond and cotton intercropping decreased the quality of cotton close to the tree canopy.When comparing the six indexes of the cotton fiber length,uniformity,CN/tex elongation,SCI and maturity,the result was that CK〉cotton around 2 m at the external canopy 〉vertical canopy〉first row inside canopy.The closer to the tree trunk,the samller of the value of each index.For the cotton SFI and Micronaire values,the result was CK〈cotton around 2 m at the external canopy〈vertical canopy〈first row inside canopy.The closer the tree trunk,the bigger of the value of each index.【Conclusion】Quality of cotton was influenced by almond and cotton intercropping,and the almond tree canopy has significant effect on cotton quality.The closer to the tree trunk,the bigger the effect is .For the eight tested indexes,almond and cotton intercropping has the most significant impact on the length,CN/tex and Micronaire of cotton fiber.
