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。

Vacuum was satisfied to the requirement of fresh-cut taro package and benefit to reduce water loss and to inhibit browning. The treatment of insufflate fresh-cut broccoli with 20mg·L-1 6-BA could delay chlorophyll reduction, inhibit ion leakage increasing and slow down the process of senescence. Fresh-cut broccoli packed with the atmosphere combination of 2.5%O2+7%CO2+90.5%N2 had high Vc and high chlorophyll content, and the senescence of the products was delayed certainly. The gas mixture of 5%O2+ 2%CO2+93%N2 could reduce the rate of respiration, chlorophyll decomposition, membrane breakdown and tissue senescence of pakchoi.

真空包装适合鲜切芋头，降低贮藏中鲜切芋头的水分损失，抑制鲜切芋头褐变发生；用20mg·L~(-1)6-BA喷洒鲜切青花菜可推迟叶绿素降解，抑制相对电导率的增加，延缓了衰老；2.5％O_2+7％CO_2+90.5％N_2MAP包装的鲜切青花菜Vc含量较高，叶绿素荧光值也较大，明显延缓了鲜切青花菜的衰老：5％O_2+2％CO_2+93％N_2混合气体抑制了青菜的呼吸作用，降低了叶绿素降解速度，减缓了细胞膜损伤及组织衰老程度。

The results as follows:(1)The decrepit rules of Lycoris leaves were: the senescence of all leaves incarnated that they turned yellow from outside to inside; to the single leaves, the main type of senescence was that it was from tip to the edge gradually, and then went to middle nervation and to the base of leave finally. There was affinity between temperature and the senescence of lycoris longituba.

具体结果如下：(1)长筒石蒜叶片衰老形态的规律为：整株长筒石蒜叶片衰老主要是从外轮叶片逐渐向内轮叶片变黄；单个叶片的衰老主要类型是从叶尖开始逐渐沿着叶片边缘向叶中脉到叶的基部。

The results revealed that treatment with mannitol retarded cell senescence,enhanced the ability of cells to redifferentiation,and reduced the activities of both peroxidase and IAA oxidase.Although treatment with 6 BA reduced the activity of peroxidase obviously,the influence of 6 BA in IAA oxidase and cell senescence was not significant.

结果表明，甘露醇处理能延迟水稻细胞衰老，提高细胞再分化能力，降低细胞过氧化物酶和 IAA氧化酶活性；6- BA( 2 mg/L )虽然明显降低细胞过氧化物酶活性，但对 IAA氧化酶及细胞衰老无明显影响。

So the depth(20-40cm)of fertilizer application could be as best depthfor delaying the senescence of flag leaf and root system and gainning highyield and high efficiency in dry land wheat.5 The effects of deep cultivation-root cutting on the senescence after an-thesis and yield had been studied in dry land wheat of high yield.the best ef-fect obtained from treatments by deep cultivation-root cutting in beforewinter stage,next by the treatment in the starter stage treatment and in con-trol,lastly by the treatment in the before winter stage and starer stage.
