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。

In order to find out completely the soil-wheat contaiminated by heavy metals in Tianjin sewage farm, we collect samples on the dry land and examinate contents of heavy metals in soil-wheat system. Firstly, the anthor evaluates that soil irrigated by sewage that has been contaminated slightly, the main polluting factors are Cd and Zn, and then the anthor evaluates soil according to different regions, soil types and irrigating water. Secondly, the anthor analyzes content and enrichment ability of heavy metals in different part of wheat, evaluates wheat is contaiminated by Cd widespreadly, only few samples polluted by Zn.Finally the anthor put up correlative analysis about heavy metal contents in the soil-wheat system, as well as plant enrichment coefficient and some physico-chemical properties of soil, and establishes a prognostic model about heavy metal content among wheat spike, soil, soil types, PH, organic matter and salinity with the quantifying theory.The prognostic accuracy of primarily contaminative factors is the best with compound correlative coefficient examining, the model can be founded.With improvement of living level, people need cleaner food.
为全面了解天津市污灌区农产品生产地土壤和旱地作物小麦的重金属污染状况，我们于2004～2005年对全市污灌区的土壤和小麦进行了采样，在对该区土壤—小麦系统中六种重金属元素(Cd、Cu、Pb、Zn、Cr和Ni)的含量进行检测的基础上，本文首先分析评价了污灌区农田土壤的环境质量总体已达到了轻度污染水平，主要的污染因子是Cd和Zn，同时对污灌区农田土壤分区县、土壤类型和不同灌水类型进行了评价；然后分析了重金属在小麦不同部位的含量与富集能力，评价了污灌区旱地作物小麦普遍遭受了Cd的污染，只有个别样点遭受了Zn的污染；最后对土壤—小麦系统重金属含量间以及植物富集系数与土壤部分理化性质间进行了相关分析，由于土壤类型是定性变量，本论文以数量化理论建立了小麦穗实中重金属含量与土壤中重金属全量、土壤类型、PH值、有机质和全盐量间的预测模型，经复相关系数检验，污灌区主要的污染因子Cd和Zn的预测精度最高，模型可以成立。

The results as followed:gaining high yield must keep higher flagleaf and canopyphotosynthetic rate after anthesis,highter flag leaf andcanopy photosyntheticrate would be benefit to keep grain filling rate andform high yield.
在旱地高产大田通过对L21与D27两品种旗叶与群体光合速率、籽粒灌浆速率及产量变化的研究，认为旱地小麦要获得高产必须保持花后高的旗叶与群体光合速率，以有利于籽粒灌浆速率维持，形成高产。
