摘　　要：以新疆棉花连续4a田间实测数据为基础,研究了不同年限膜下滴灌棉田非生育期（3月和10月）土壤盐分的变化。结果表明,膜下滴灌棉田非生育期,10月0~60cm土层含盐量大于3月,而60~100cm土层含盐量变化规律不明显。随着滴灌年限的增加,膜下滴灌棉田土壤含盐量呈增加趋势。Based on the measured consecutive 4-year data in cotton field of Xinjiang, the changes of soil sa- linity in March and October were studied under mulched drip irrigation in different years. The results indi- cated that soil salinity in 0~60 cm soil layer was higher in October than that in March while soil salinity in 60~100 cm changed without obvious regularity. With the increasing of drip irrigation time, soil salinity tended to increase.
