摘　　要：为了找出最佳的盐碱地改良措施,该试验用有机肥、复合肥和新型生物改良剂(TM、EM)对土默川碱化土壤进行改良。施用改良剂EM后,土壤全盐下降的幅度为23.21%~48.43%,p H下降的区间为3.88%~10.63%,碱化度下降3.02~4.06个百分点,土壤养分也均有提高,速效磷、速效钾、有机质、微生物碳量分别比CK增加了43.41%,32.37%,39.75%,55.68%。结果表明,生物改良剂EM的改良效果较好。Organic fertilizer, compound fertilizer and now biological modifier, EM （TM） were used modified alkaline soil in Tumochuan plain. Throuth applacation of modifor EM, soil salt descend range was 23.21% to 48.43%, pH decline range was 3.88% to 10.63%,and soil basicity reduced range between 3.02% and 4.06% ,but nutrients in the soil were increased. Available phosphorus and available potassium and organic matter,soil microbial biomass carbon respectively increased more than CK by 43.41%, 32.37%, 39.75%, 55.68%. The results showed that the biological modifier - EM improved effect.
