%X 在新疆自然生态环境下，以‘新陆早32号’为材料进行大田试验， 对2种机采棉行距配置模式（66 cm+10 cm、72 cm+4 cm）下的冠层结构、光合特性及产量进行研究。结果表明：66 cm+10 cm模式下形成的冠层结构较72 cm+4 cm模式更有利于棉花生育后期通风透光，从而促使叶片净光合速率增强，持续时间长，使得66 cm+10 cm模式籽棉产量显著高于72 cm+4 cm模式，2模式间单铃数呈显著性差异。<br>Taking ‘Xinluzao 32’ as experimental material and under the treatments of two row spacing patterns (66 cm+10 cm,72 cm+4 cm).The cotton yield, canopy structure and photosynthetic indexes were studied in Xinjiang.The results showed that canopy structure formed under the pattern of 66 cm+10 cm was compared with that of 72 cm+4 cm pattern, it was more conducive to the cotton ventilation and light transmission at late stage of growth,and it could promote cotton leaves to have strong and long-time net photosynthetic rate .The cotton yield under treatment of 66 cm+10 cm pattern was significantly higher than that of 72 cm+4 cm pattern, the boll number per plant showed significant difference.
