摘　　要：研究了不同垄作方式对土壤生态环境及棉花产量品质的影响.结果表明,垄作栽培能提高0～20 cm土壤温度,可以降低土壤容重,提高土壤孔隙度和通气性.垄作栽培适宜的垄高（15 cm）能促进棉花早生快发,稳长增蕾铃,子棉产量达4 593 kg/hm2,与垄高25 cm和平作相比,差异达极显著水平.Ecological environment of soil and yield and quality of cotton was studied with different kinds of ridge planting.The results showed that ridge planting could increase the temperature in 0～20 cm soil,reduce soil bulk density,improve soil permeability and physical properties of soil moisture.The optimal height for ridge planting was 15 cm,which could promote the growth and development of cotton.The seed cotton yield was 4 593 kg/hm2,with significant difference from that of 25 cm height and flat-planting.
