摘　　要：通过研究不同熟性棉花品种棉铃空间分布及产量品质形成差异,为该地区选择适宜熟性品种提供理论依据。在南疆塔里木盆地进行不同熟性棉花品种棉铃空间分布及产量品质形成差异的研究。结果表明:不同熟性棉花品种的棉铃脱落率表现为早熟>中熟>中早熟;"三桃"比例中伏前桃表现为早熟>中熟>中早熟,伏桃表现为中早熟>中熟>早熟,秋桃表现为中熟>早熟>中早熟;单株铃数和单铃质量表现为中熟>中早熟>早熟;产量表现为中早熟>中熟>早熟;上半部平均长度和断裂比强度表现为中早熟>中熟>早熟;马克隆值表现为中熟>中早熟>早熟。中早熟品种不论在成铃率和"三桃"比例,还是在产量、品质等方面都表现出较强的适应性,中熟品种次之,早熟品种不太适应塔里木棉区种植。在目前种植条件下,中早熟品种更适合在南疆塔里木棉区种植。This research studied the cotton boll spatial land cotton cultivars with different maturity,to provide distribution,the yield and fiber quality of up- theoretical basis for selecting suitable maturity cultivars in this area. A field experiment was conducted in Tarim Basin of south Xinjiang with the ma- terials of different maturity cotton cultivars （early, medium and middle early maturity）. The result showed that the boll abscission rate （BAR） of cotton cultivars was sequenced early,medium,and mid- dle early maturity in descending order. For the three bolls ratio, the pre-summer bolls from high to low was the early, medium, middle early maturity, the summer bolls was the middle early, medium, early maturity,and the autumn bolls was medium,early,middle early maturity. The bolls per plant and sin- gle boll mass from higher to low were the medium, middle early, early maturity cultivars. The yield, fi- ber length and the break strength were the middle early, medium, early maturity. The micronaire value was the medium, middle early, early maturity. The middle early maturity cultivars were better than the others, with lower BAR ,higher boll retention, better three boils ratio and higher yield and fiber quali- ty,and followed by the middle maturity cultivar. And the early maturity cultivars were not suit for the Tarim Basin. Combining with the experiment results and production practice, it could be concluded that,in the current planting condition, the middle early maturity cultivar is the most suitable cotton cultivars planting in Tarim Basin of south Xinjiang.
