不同氮输入梯度下草甸沼泽土反硝化损失和N2O排放

The level of soil total phosphorus content as follows : marsh soil Soil meadow black soil forest brown soil .

土壤全磷含量高低表现为：沼泽土黑土草甸黑土森林棕壤土。

Effects of Land Use Change on Carbon Contents of Marsh Soil in the Sanjiang Plain

土地利用对沼泽湿地土壤碳影响的研究

Marsh soil physical and chemical properties differ prominently .

湿地各样地土壤理化性质存在显著差异，海堤防护林地、苇塘草地、大米草等滩涂的土壤理化性质均要优于对照地潮间海滩。

Response of Nitrification-Denitrification and Carbon Mineralization to Nitrogen Input in Meadow Marsh Soil

草甸沼泽土壤硝化-反硝化作用和有机碳矿化对氮输入的响应

Multiple regression analysis showed that the nitrogen mineralization potential of meadow marsh soil was the main factor affecting DOC production .

多元回归分析表明，草甸湿地DOC的生成主要受土壤氮矿化潜势制约（P<0.05）。

In frozen-thaw process of peat mire soil , the temperature gradient of lower soil is larger than meadow marsh soil .

泥炭沼泽土冻结过程中，下部土壤的温度梯度较草甸沼泽土大。

In melting process , more water is blocked in upper layer because peat mire soil permeability is lower than meadow marsh soil .

融化过程中，由于泥炭沼泽土渗透性较草甸沼泽土低，土壤化通后，其表层能滞留更多的水分。

The results showed : ( 1 ) The methane production rates reached the maximum on the third day in three kinds of plant marsh soil , then gradually decreased with incubation time .

本文研究结果如下：（1）3种植物沼泽湿地土壤的CH4产生率在培养前期达到最大值后，随培养时间逐渐降低。

Between the four soil types the degree of similarity of soil animals were higher , mostly middle-similar , only the marsh soil and meadow soil is very similar .

四个土类间土壤动物的相似程度均较高，大多为中等相似，只有沼泽土和草甸土为极相似。

In meadow marsh soil , temperature had more evident effect , where nitrification-denitrification had a significant positive correlation with the soil temperature at the depths of 5 cm , 10 cm and 15 cm ( P0.05 ) .

温度对前者硝化-反硝化作用的影响比后者更为明显，其反硝化速率与5、10和15cm地温均呈显著正相关（P0.05）；

Effect of Returning the Crop Stack into Subsoil on Improving The Marsh Bog Soil and Drainage

秸秆心土还田改良沼泽化土壤排涝效果的研究

The result shows that the fertility of different types of soil is obviously different , marsh peat soil and irrigated cubic thick soil have the highest fertility , irrigated flat thick soil has medium fertility , and shifting sand soil has the poorest fertility .

分析结果表明不同类型的土壤肥力差异较明显，沼泽泥炭土、灌耕厚立土的养分含量最高，灌耕厚平土次之，流动风沙土最差。

Effect of marsh manure on soil fertility , yield and quality of fruit in early mature orange

沼肥对早熟蜜柑土壤肥力及产量品质的影响

But coping with salt is not the only challenge for plants in the salt marsh . , soil there is dense and very low in oxygen ,

但是，适应海碱地带过量的盐分并不足以保障他们的生存，因为那儿的泥土非常紧密，而且含氧量极低，
