中文摘要	为探讨传统种植(1穴1株)和集群种植(1穴3株)方式下棉花产量及田间微环境差异,在甘肃河西走廊干旱荒漠绿洲区对传统种植和集群种植方式下棉花的产量和微环境进行对比研究。结果表明,集群种植下棉花的经济产量显著高于传统种植,集群种植下穴距配置对产量产生一定的影响,穴距为28 cm时棉花的单铃质量和皮棉产量最高,并且显著提高了棉花衣分;集群栽培可有效增加单位面积铃数,提高棉花中后期群体光截获率和冠层湿度,降低棉花冠层温度,对棉花群体内部CO_2摩尔分数仅有微弱的影响。因此,相对于传统种植方式,集群种植可显著改善棉花群体微环境,进而提高棉花的经济产量,且穴距为28 cm是集群种植获得较高产量的最佳穴距。
英文摘要	In order to investigate the difference of yield and field microclimate of cotton under traditional planting (one plant in a hole) and cluster planting patterns (three plants in a hole), yield and field microclimate were studied between traditional planting and cluster planting pattern in the desert oasis region of Hexi corridor. The results showed that the economical yield of cotton in cluster planting was significantly higher than traditional planting. The hole spacing of cluster planting had some effects on yield, and it had the highest boll weight and lint yield with hole spacing 28 cm and the lint percentage was significant enhanced. The total boll number per area in cluster planting was increased, the canopy light interception and canopy humidity in the middle and last stage were enhanced, but the canopy temperature was reduced. The canopy CO_2 concentration of every layer was effected by cluster planting, but not significantly. Therefore, the canopy microclimate of cotton was improved in cluster planting and the economical yield was enhanced, and the 28 cm was the suitable hole spacing in cluster planting which can achieve high economical yield.
