摘　　要：[目的]以河套地区盐碱土为对象,筛选适宜盐碱地使用的土壤调理剂并评价。[方法]对使用不同土壤调理剂后作物产量、土壤有机质含量、盐碱特征数据进行比较分析。[结果]供试调理剂对向日葵产量的影响均未达到显著水平;供试调理剂对土壤有机质含量有明显提高作用,0~20 cm土层土壤有机质含量较对照提高了33.5%~60.0%;供试调理剂对土壤pH有降低作用;中农创达微生物菌剂和益百稼调理剂可有效降低土壤全盐含量。[结论]综合对土壤性质及作物产量的影响,中农绿康微生态制剂、中农创达微生物菌剂、农邦沃土微生物菌剂3种调理剂比较适宜河套地区盐碱地。[Objective]To select and evaluat the soil conditioner suitable for saline-alkali soil in Hetao area as the object.[Method]Crop yield and soil organic matter content salt-alkali characteristic data were compared and analyzed by different soil conditioner.[Result]The effects of the tested conditioner on the yield of sunflower were not significant.The tested conditioner significantly increased the soil organic matter content in the 0~20 cm soil layer by 33.5%~60.0%compared with the control.The tested conditioner can reduce the pH value of soil.ZhongNongchuangda microbial agent and YiBaijia conditioner can effectively reduce the soil total salt content.[Conclusion]Based on the comprehensive effects on soil properties and crop yield,three kinds of conditioning agents,Zhongnonglvkang microorganism agent,Zhongnongchuangda microorganism agent and Nongbang fertile soil microorganism agent,are more suitable for saline-alkali land in Hetao area.
