中文摘要	为了对劣质土及再生水灌溉下农田水分高效利用进行研究,通过野外试验的方法,以内蒙古干旱区城郊建筑回填土农田再生水灌溉玉米为研究对象,系统研究了再生水灌溉劣质土对玉米生长及土壤理化性质的影响。试验期间共灌溉4次水,共设不同再生水(Z)清水(Q)5个处理,分别是T1(4Q)、T2(2Q2Z)、 T3(1Q3Z)、T4(1Q2Z1Q)、T5(1Q1Z1Q1Z)5种模式。结果表明:建筑回填土下再生水灌溉玉米能显著增加玉米干物质、株高、叶面积及产量,且增产最大为15.91%;短期再生水灌溉不会对玉米重金属含量产生影响;再生水灌溉后土壤容重呈增加趋势,长期再生水灌溉会对深层土壤盐分累积产生潜在风险。
英文摘要	In order to promote the efficient use of the inferior soil and reclaimed water in cropland,this filed experiment selected construction backfilled soil in suburbs in arid area of Inner Mongolia as research object to study the influence of reclaimed water irrigation on the maize growth and physical and chemical properties of construction backfilled soil.During the experiment period,the filed was irrigated 4times,and 5different irrigation modes were established,from reclaimed water(Z)to clear water(Q).The irrigation modes were T1(4Q),T2(2Q2Z),T3(1Q3Z),T4(1Q2Z1Q)and T5(1Q1Z1Q1Z).The results showed that the reclaimed water irrigation on construction backfilled soil could increase the dry matter,plant height,leaf area and yield of maize.The maximum increase of maize yield was 15.91%.The short-term reclaimed water irrigation did not influence the heavy metal content of maize.The soil bulk density showed an increasing trend after the reclaimed water irrigation.And the long-term reclaimed water irrigation could induce the potential risk of the salt accumulation in deep soil.
