The results showed:（1）Accompanied with decreasing of light intensity, leaf length, width and leaf thickness of Dichondra repens increased initially and then decreased. They were up to the peak under 76.19 % transparency. The length of petiol extended with the decreasing of light intensity, but the leaf morphology of Dichondra repens was no significant effect.

结果表明：（1）随着光照强度的降低，马蹄金叶片的长度、宽度及厚度均表现出先增大后减小的趋势，在76.19％光照强度下达到最大值；叶柄长度随着光强的减弱而增长，叶片的形态并未发生显著变化。

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。

After 48h of exposure, the color of leaf of Egeria najas became greenish badly and the leaf was conglutinated, and the chlorophyll content of leaf declined significantly when the Hg concentration were above 2.00mg/L.By the changes of chlorophyll content, the lethal concentration of Hg to Egeria najas was 0.10-2.00mg/L.

处理48h以后，Hg~(2 )浓度人于1.00mg/L实验组中的叶片褪绿严重而且叶片相互粘连，叶片叶绿素含量明显低于对照组，从中可以粗略看出Hg(2-)对细叶蜈蚣草的致死浓度为0.10-2.00mg/L。

We will start with a picture of a leaf bug (Author's Note: I am a far cry from an entomologist, and the bug looks like a leaf, hence leaf bug, tada).

我们将开始与图片叶错误（作者注：我相距甚远的一名昆虫学家，和错误看起来像一片树叶，因此，叶错误， tada ）。

一些常用的叶子像tejpat ，香菜叶，巴叶和薄荷叶。

The results showed that the POD activity was higher in the sporophyll than that in the stems and leaves in which the POD activities were weak from bottom to top in native plant. For the Japanese plant, the POD activities of the stems and leaves were the same in all positions. However, the activity was slightly higher in mid-portion of a leaf than that in stems. The high enzyme activities were observed in mid-bottom stems in the half-bred plant, and the activity was higher in bottom leaf than that in mid-top leaf.

结果表明：3个裙带菜群体的POD同工酶其孢子叶活力都相对强于其它部位；日本裙带菜茎和叶的各部位POD酶活力相同，但叶中部的酶活力稍强于茎；自育裙带菜茎底部和茎中部的POD酶活力较强些，而叶底部的酶活力较叶中部和顶部的强；本地裙带菜的茎和叶由底部到顶部POD酶活力逐渐变弱。

This article analysis the effects of canopy structure: cultivated density and canopy thickness, canopy azimuth angle and gradient, canopy height and interline distance, canopy stretch degree, leaf area coefficient, leaf area density; fruit photosynthesis characteristics: leaf optical characteristics required, changes in law of fruit Pn's season and day; the internal and external effects of photosynthesis; light interception and distribution, the paper puts forward some exiting problems and provides direction for future research.
