摘　　要：选用中早熟常规棉花品种为材料 ,采用裂区设计 ,研究了地膜覆盖对中早熟棉花品种的影响。结果表明 :地膜覆盖对中早熟棉花品种蕾期的株高、果枝数、第 1果枝节位以及伏前桃有极显著或显著的正面效应 ,但对伏桃和秋桃有显著的负效应 ,对单株铃数、单铃重、衣分、皮棉产量及纤维品质的影响不显著。The influence of plastic film mulching on middle-early maturation variety was studied by split-plot design test. Plastic film mulching only has positive effect on height,number of productive branch and node number of first productive branch in square period for middle-early maturation variety, but has prominent minus effect to summer-boll and autumn-boll, and has no prominent effect to boll weight,lint percentage,lint yield and quality of fiber.
