摘　　要：以早熟棉冈0379品种为材料,研究麦后棉直播不同密度(4.5万株、6.0万株、7.5万株/hm2)和施肥量(75、120、165 kg/hm2)对产量及主要性状的影响。结果表明,种植密度6.0万株/hm2,施肥量165 kg/hm2的处理,其子棉产量为3 520.95 kg/hm2,皮棉产量为1 662.00 kg/hm2,显著高于其他处理,麦后棉直播可以达到较高的产量水平。Used Gang-0379, an early maturing cotton, as research material. To investigate the effect of different planting densities and different fertilizer levels on cotton yield and agronomic trait, planting pattern experiments in field were conducted, with crossover-randomized experimental design which contains three density levels（45 000、60 000、75 000 plants / hm^2） and three fertilizer levels（75、120、165 kg / hm^2）. The results showed that take the design pattern of 60 000 plants per hectare and165 kg per hectare would lead to a better result of 3 520.95 kg / hm^2 for seed cotton yield and 1 662.00 kg / hm^2 for lint cotton yield, with remarkable difference to other design patterns.
