摘　　要：通过土柱模拟试验,研究了不同土壤改良剂对新疆盐碱土壤的理化性状的影响。2种改良剂均能使重度盐渍化土壤迅速脱盐降低土壤盐碱性,改善盐碱土土壤性质。旱地龙能显著降低CO32-、HCO3-、Cl-含量,禾康能显著降低SO42-、K＋＋Na＋、Mg2＋含量。通过田间试验对比分析2种改良剂应用效果,结果表明,施用FA旱地龙增产21.1%,施用禾康增产17.8%。The filde experiment with monolith lysimeters was carride out to studu the effect of different soil modifier on the characteistict of slil cheical,The results indiate that 2 kinds of soil modifier could enhance salt leaching significautly and decreasded soil alkalization,FA Handilong could reduce CO2-3、HCO-3 and CI-content,hekang could reduce SO2-4、K＋＋Na＋ and Mg2＋ coutent.The fidld trials were carried out to compare and analyse the effects of two siol amendment were highest when the cost of FA Handilong were considerde.
