So the variety of L21 andLainong9217 should be planted in dry land of high yield,and the variety ofLainong8834 and YD27 in dry land of middle yield,and gaining high yieldand high efficiency.2 The researches on the flag leaf and root system senescence after anthesisand yield were studied in dry land wheat of high yield,the activity of super-oxide dismatase and catalase、and the soluble protein content、Cytokinincontent in wheat flag leaf and root system after anthesisand Cytokinincontent in grain decreased slowly,and the content ofmalondiadehydeand the Abscisic Acidcontent in wheat flagleaf and root system and the Abscisic Acidcontent in grain increasedslowly,meanwhile keep higher root vigor and the root vigor decreased slow-ly,the result would be benefit to delay the senescence and gain high yield.3 The effects of soil thickness on the senescence of flag leaf and root sys-tem、nitrogen distribution and utilization and water consumption law andyield in dry land wheat had been studied in soil column and field.

通过大田条件下旱地高产小麦耗水规律及产量变化的研究表明，4个品种耗水量、产量、水分生产率、籽粒产量中来自花后光合器官输送的比例及综合效益评判结果均以鲁麦21和莱农9217为高，而莱农8834和烟D27则与此相反，因而在旱地高产麦田应以种植鲁麦21和莱农9217为主，中产麦田以莱农8834和烟D27为主，以获得高产高效。2在旱地高产大田对鲁麦21与烟D27两品种花后旗叶、根系衰老及产量变化进行了研究，认为花后旗叶与根系SOD、CAT活性、可溶性蛋白质含量、i-PAs含量及籽粒iPAs含量降低缓慢，MDA含量、ABA含量及籽粒ABA含量增加缓慢，同时保持较高的根系活力且下降缓慢，有利于延缓衰老，形成高产。3土层厚度对旱地小麦花后衰老、氮素分配利用及产量的影响进行了研究，随土层厚度加深，根系活力、根系与旗叶SOD、CAT活性及可溶性蛋白质含量增加，MDA含量减少，土层愈薄，其根系与旗叶衰老愈快。
