Under 50%, 60% and 70% field capacity, ammonium nitrogen content in soil with water soluble felted and coated fertilizer was in positive correlation to water content, and nitrate nitrogen content after 24 d was more than that with urea treatment.

在田间持水量50%、60%、70%条件下，微水溶性胶结包膜缓释肥料土壤铵态氮含量变化与水分呈正相关关系，24 d后硝态氮含量呈高于尿素处理趋势。

Owing to the influence of industry sewage, living sewage, the lixiviate things of soil in the wet-dry zones and the falling of water self clean ability, the water quality of reservoir will be influenced and the fluctuation in stage will share a inverse relationship with the regression of river level in the natural state.

由于受到陆地污染物的进入、淹没地污染物的浸出以及水体自净能力下降的影响，消落带水环境存在着岸边污染带和水陆交叉污染两方面的问题，将严重影响库区水环境质量，扰乱该地区原生生态系统，影响三峡库区生态环境安全。

However 528 nm and (dR716-R496)/(R716+R496) were the most important waveband and index to evaluate the variation of Fv/Fm on Mangifera indica and Decussocarpus nagi. At water deficit photosynthetic capacity and stomatal conductance reduced by decreasing soil water potential.

在平地结果显示，不同生态习性之植物其Fv/Fm对温度及光度之反应各异，并得知528 nm为推估芒果Fv/Fm萤光变化的重要波长，其反射率一次微分值为推估芒果Fv/Fm之最佳指数，NDVIdR716-496则为推估竹柏Fv/Fm最准确之指数。

When water-content was over 90-100% or low 40-50% in the soil, it affected the growth of Sabaigrass, as a result, the number of green leaves decreased and the length of green leaves shortened. In June that Sabaigrass grew rapidly, water logging in field significantly influenced vegetate and restrained to the development of tillers.

土壤含水量过高(90～100％)和过低(40～50％)，龙须草整个生育期没有分蘖快速增长的现象，进入8月份，甚至还出现分蘖死亡的现象，叶片的生长也受到很大影响，叶片总数极显著地减少，叶片的长度缩短，长于或等于80cm的叶片根本没有。

The study results indicated: The growth and output of the Sabaigrass was in orderon condition that soil holding water ratio was between 70% and 80%. The segregatingbranch of Sabaigrass have not grow rapidly in the procreative period when the soilheld higher(90～100%) or lower water (40～50%), and in August the death ofsegregating branch appeared.The growth of laminae was also impacted, the quantityor length of laminae, even shorter than 80cm. Finally with the result that the outputdecreased evidently.In June, the nutrition blooms in this time, the growth ofsegregating branch of Sabaigrass was affected by the field waterlogging, the caudexand segregating branch were half less than in the normal condition.

如果土壤含水量过高(90～100％)和过低(40～50％)，龙须草整个生育期没有分蘖快速增长的现象，进入8月份，甚至还出现分蘖死亡的现象，叶片的生长也受到很大影响，叶片总数极显著地减少，叶片的长度缩短，长于或等于80cm的叶片根本没有，最终导致产量显著降低；尤其是在6月份龙须草营养旺盛生长的时期，大田淹水极大地影响龙须草的生长，抑制分蘖的发生，收获时龙须草的总茎蘖数只有正常的一半。

A portable photosynthesis system made by PPSYSTEM Ltd. was used to study the photosynthetic properties of 3 cultivarsof Rubus idaeus under the field conditions. The results indicated that the individual leave net photosynthetic rates had 2 peaks during a day,an obvious photosynthetic midday slump was observed in A,there was a significant difference in midday depression among the 3 cultivars;evaporation rates of B and C had 2 peaks during a day,while A had 1 peak,and an obvious midday slump was observed in B and C;Stomatic conductance is the key factor of midday slump;Compared with B and C,A had a higher water using efficiency,which will consume less soil water.

利用英国PP-SYSTEM公司生产的TPS-1便携式光合作用测定系统，对3个树莓品种的光合特性进行了比较研究，结果表明树莓叶片光合速率日变化呈双峰曲线，A品种&日中低落&现象明显，B、C品种不甚明显；B、C品种的蒸腾速率日变化曲线基本上为双峰型，日变化过程中的&午休&现象非常明显，而A品种为单峰型，日变化过程中的&午休&现象不甚明显；此外，叶片气孔导度与叶片光合速率的日变化趋势基本一致，呈平行变化趋势，说明气孔导度是影响光合速率的直接因子；较B、C品种而言，A品种具有较高的水分利用效率，说明其更能节约并有效地利用土壤水分。

Water samples were extracted and purified and collected by solid-phase extraction LC-18 column.
