中文摘要:
      在新疆南疆自然生态条件下，研究了杏棉间作对棉花产量及其构成因素的影响。结果表明：间作棉花的LAI在整个生育期低于单作，且峰值出现早，后期下降缓慢，比单作低15.9%；叶片的净光合速率Pn与SPAD值联系密切，盛花期前叶片的Pn、SPAD值增长快，间作的叶片Pn和SPAD值均低于单作；间作棉花地上部干物质快速积累持续期比单作少10.7 d，最大积累时间间作棉花比单作早4.7 d，最大积累量间作比单作少0.42 g/(d·株)；间作棉花的“三桃”(伏前桃∶伏桃∶秋桃)比例为0.14∶1∶0.14；皮棉产量为1 395.3 kg/hm2，比单作低41.2%；经济收入间作比单作高37.8%。
英文摘要:
      Under the natural environment in south Xinjiang, we studied the effect of apricot-cotton intercropping on cotton yield and yield components, aimed at providing the theoretical basis for efficient cultivation technology of cotton in the apricot-cotton intercropping system. The results showed: The LAI of intercropped cotton was lower than that of sole cotton through the whole growth stage, and the peak of LAI appeared earlier and LAI of intercropped cotton decreased slowly at the later stage, and was lower than that of sole cotton by 15.9%; There was a close relation between leaf Pn and its SPAD value, before peak flowering, both the leaf Pn of intercropped cotton and sole cotton increased fast and so was the leaf SPAD value, but both of which were lower than that of sole cotton; The fast accumulating period of dry matter above ground of intercropped cotton was shorter than that of the sole cotton by 10.7 days, and t he max dry matter accumulation time of intercropped cotton appeared earlier than that of sole cotton by 4.7 days, and the max dry matter accumulation amount was less than that of the sole cotton by 0.42 g per plant; The ratio of the three kinds of bolls of intercropped cotton was 0.14∶1∶0.14, and the lint yield was 1 395.3 kg/hm2 lower than that of the sole cotton by 41.2%; The economic income of intercropped cotton is higher than that of the sole cotton by 37.8%.
