淹水

The results show that:①The forest soils have the stronger nitrification, but also the nitrification in surface horizon is stronger than the undersoil's.

结果表明：①森林土壤有较强的硝化活性，且表土层比底层土强，同时根际土利于硝化作用进行，根际效应R/S在4.5左右；②淹水厌气培养24h，-N的消失率为52%～58%，占第10天的55%～71%，且表土层-N的消失率比底层土大；③参与同化反硝化作用的还原酶活性较强，在培养24h后，被还原的基质数量占加入基质数量的70%～90%。

The effective factor of phosphorous release from soil in Water-Fluctuation-Zone of the Three Gorges Reservoir.;2. The water-fluctuation-zone of reservoir and big river had special environmental characteristics that were a joint of aquicolous and terrestrial ecological system.

以三峡库区消落区典型江段万州断面为试验基地，以释磷能力较强的紫色土为对象，根据三峡水库消落带的&干湿交替&空间和时间特征，进行万州断面土壤磷释放的实验室模拟试验，分析了周期性&淹水-落干&干湿交替对土壤磷释放的影响。

In addition, the content of OlsenP of soil with plants was higher than that of soil without plantfor soils with Cynodon dactylon and Ficus tikoua by 215％ and 127％.Key words: Three Gorges Reservoir; WaterFluctuationZone; phosphorous release; effective factor

种植植物的土壤在淹水后OlsenP含量大于土壤直接淹没时的释放量，种植狗牙根和野地瓜藤的土壤中OlsenP分别较未种植物土壤释放量高出215％和127％。

Objective: To study the different and the variety of four organic acids in leaves of Isatis indigotica among different cultivated populations in water stress condition and healthy plant.

中文摘要：目的：检测北京、内蒙古、河北和陕西等4个栽培居群菘蓝叶片中草酸、苹果酸、柠檬酸和抗坏血酸等4种有机酸成分含量的差异及在淹水胁迫下的变化。

Cumulative NH4+-N is a good evaluating index of soil N-supplying not only for the first season crop, but also for two successive season crops. ND is more correct in revealing the potential mineralizable nitrogen when SON was regarded as mineralized N, although cumulative SON alone is not a good index for the potential of mineralizable nitrogen. And cumulative TSN could also be taken as an index for the potential mineralizable nitrogen to some extent.

淹水培养期间铵态氮累积量是评价可矿化氮的较好指标，不仅适宜于第一季作物，而且也适用于连续两季作物；SON累积量不能单独作为；SON累积量不能单独作为反映可矿化氮的指标，但用ND反映土壤可矿化氮潜势时，包括SON后更加准确；TSN在一定程度上能够反映土壤可矿化氮。

The Mount Beigu wetland is nearby Yangtze River, which undergoes seasonal flooding, and its dominant plants are Phragmites communis and Phalaris arundinacea.

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
