摘　　要：为了探究简化栽培措施对不同类型棉花品种产量和纤维品质性状的影响程度,以3种类型棉花品种为试验材料,在中等密度(5.2万株/hm^(2))条件下研究常规整枝和不整枝2种栽培方式对棉花产量及纤维品质性状的影响。结果表明整枝措施对不同类型棉花品种的铃重、籽指、衣分、纤维长度、马克隆值、整齐度指数、伸长率均没有显著影响,对纤维比强度影响显著(F=7.27);整枝和品种类型对棉花产量构成因素(铃重、籽指、衣分)和纤维品质性状均没有互作效应。在种植密度5.2万株/hm^(2)时,整枝措施能提高棉花品种的纤维比强度,对棉花产量构成因素(铃重、籽指、衣分)无显著影响。The main objective is to explore the effects of simplified cultivation on the yield and fiber quality characters of different cotton varieties.Using three different cotton varieties, the effects of normal pruning and non-pruning on cotton yield and fiber quality were studied under moderate plant density(52000 plants/hm^(2)).The results showed that pruning measures had no obvious effects on boll weight, seed index, lint percentage,fiber length, micronaire value, uniformity index and fiber elongation, but significantly influenced the fiber strength(F=7.27).There was no significant interaction effect between pruning measures and varieties on yield components and fiber quality traits.Pruning significantly improved fiber strength of cotton variety under moderate plant density(52000 plants/hm^(2)), but it had no significant effect on yield components(boll weight,seed index and lint percentage).
