摘    要:目的]研究聚马来酸(PMA)对次生盐渍化土壤盐分的影响。方法]设4个处理,其中,处理1为清水对照,处理2施用130g/m^2PMA.处理3施用260g/m^2PMA.处理4施用B、Zn、Fe复合微肥1g/m^2,3次重复,随机区纽设计,测定不同处理对次生盐渍化土壤盐分的影响。结果]处理3对次生盐渍化土壤影响最大,EC值为2.6mS/cm,其次为处理2,EC值为3.0ms/cm;处理2SO4^2-含量最低,达3.688g/kg,其次为处理4,为7.024g/kg;处理3Na^+浓度最低,为11.81g/kg,其次为处理2,为15.13g/kg;处理3Mg^2+浓度最低,为1.943g/kg,其次为处理2,为2.254g/kg。结论]PMA可以降低土壤盐分,改善土壤的盐渍化程度。

关 键 词:聚马来酸  棚室  次生盐渍化  土壤盐分

Abstract:Objective]The study aimed to research the effect of PMA on salt of secondary salinization soil.Method] A randomized block design with four treatments and three repeats was adopted to determine the effect of different treatments on the salt of secondary salinization soil.Result] The treatment 3 had the biggest influence on the secondary salinization soil with the EC value of 2.6 mS/cm,then followed by treatment 2 with the EC value of 3.0 mS/cm;treatment 2 had the lowest SO42-content with 3.688 g/kg,follow...
Keywords:PMA  Plastic greenhouse  Secondary salinization  Soil Salt
