摘　　要：针对冀东滨海地区土壤结构差,盐碱化程度高,棉花出苗率低、保苗难的现状,对棉花不同种植模式土壤盐分变化及对出苗率的影响进行了研究。结果表明,0～5cm耕层盐分的变化幅度最大,有效抑制表层盐分的升高是棉花苗全苗壮的关键;膜侧播种、沟边播种由于播种位置盐碱轻、墒情易掌握,出苗全,是较适宜的棉花种植模式。Aiming at the status of poor soil structure, high degree of salinity, low cotton germination rate and hard seedling in east of Hebei Province coastal area, effects of different cotton planting patterns on soil salinity and germination rate were studied. The result showed that there is the biggest change of salinity at 0 -5 cm plow layer, and it is key to control increasing salinity in topsoil;because of light salinity, moisture easy to master and full emergence in planting location, side membrane planting and side ditch sowing are the most appropriate model of cotton cultivation .
