摘　　要：为选择适宜旱地宽厢宽带种植的玉米品种,采用随机区组设计方法,于灌浆期对不同玉米杂交组合在净作与旱地宽厢宽带种植模式中穗位叶叶片的光合速率、叶面积、叶绿素含量以及成熟期的产量进行比较分析。结果表明,贵单501和兴单12较适合于宽厢宽带模式。贵单501和兴单12的光合速率分别比净作中边1行高出9.04μmol.m-2.s-1和0.83μmol.m-2.-s1;叶面积分别比净作中边1行增大6.8%和4.6%;叶绿素含量分别比净作边1行提高16.3%和14.7%;产量比净作仅减少6.4%和9.1%。边行优势越明显的玉米杂交组合在旱地宽厢种植模式中能获得与净作相当的产量。In order to choose the suitable maize variety used in arid land width theater box wide band plant pattern,the method named the randomly block design is used in this experiment. The photosynthetic rate, the leaf area, the chlorophyll content of the ear leaf in the grouting period and the output in the mature period of the different maize hybrid combination cultivated individually in normal single plant patterr, and the arid land width theater box wide band plant pattern have been analyzed. The results showed that Guidan 501 and Xingdan 12 were more suitable to width theater box wide band model, compared with that of the last line of the band in normal single plant pattern. The photosynthetic rate of Guidan 501 and Xingdan 12 cultivated in width theater box wide band model increased by 9.04μmol·m^-2·s^-1 and 0.83μmol·m^-2·s^-1,the leaf area of Guidan 501 and Xingdan 12 increased by 6.8% and 4.6% , the chlorophyll content of Guidan 501 and Xingdan 12 increased by 16.3% and 14.7% , the yield of Guidan 501 and Xingdan 12 only deceased by 6.4% and 9.1%. The yield of those maize combinations which have the obvious last line advantage in arid land width theater box wide band plant pattern is almost the same as that cultivated in normal single plant pattern.
