摘　　要：以大庆地区盐碱土为研究对象,通过在添加一定比例秸秆的盐碱土中种植玉米,探讨秸秆对盐碱土的改良效果。在盐碱土及添加秸秆的盐碱土中盆栽玉米,待三叶期时,测定玉米幼苗叶绿素、丙二醛含量、渗透调节物质以及抗氧化物酶活性的变化,阐明秸秆对盐碱土的改良效果。结果表明,盐碱土中添加秸秆后,玉米幼苗叶片可溶性糖、可溶性蛋白和丙二醛含量显著降低(P<0.05);叶绿素含量和过氧化氢酶活性的变化不显著(P>0.05)。盐碱土中添加秸秆后,玉米幼苗通过改变细胞膜脂过氧化作用和调节渗透调节物质含量来降低盐碱伤害。Taking the saline-alkali soil in Daqing area as the research object,the improvement effect of straw on the saline-alkali soil was discussed by planting corn in the saline-alkali soil with a certain proportion of straw added.Pot maize was planted in saline-alkali soil and saline-alkali soil with straw added,and the contents of chlorophyll,malondialdehyde,osmotic regulation substances and antioxidant enzyme activities of maize seedlings were measured at the three-leaf stage,to elucidate the improvement effect of straw on saline-alkali soil.The results showed that the content of soluble sugar,soluble protein and malondialdehyde in leaves of maize seedlings decreased significantly after adding straw to saline-alkali soil(P<0.05);there were no significant changes in chlorophyll content and catalase activity(P>0.05).After adding straw to saline-alkali soil,maize seedlings reduced saline-alkali injury by changing cell membrane lipid peroxidation and regulating the content of osmotic regulators.
