- 摘要:
- 为研究氮沉降对黄土丘陵区林地土壤可溶性氮及可溶性有机物官能团特征的影响，设置6个不同施氮水平0，2.8，5.6，11.2，22.4，44.8 gN/（m2·a）的盆栽油松，连续培养五年，对油松根际、非根际可溶性氮及其组分进行了研究。结果表明：氮添加会显著增加土壤可溶性总氮、可溶性无机氮和可溶性有机氮含量、可溶性有机氮占可溶性氮的比重随氮沉降的增加而成倍增加，可溶性氮及其组分均未表现出明显的根际效应。与此同时，通过不同紫外特征的研究，发现较低和较高水平氮沉降均能增加根际土水溶性有机物中芳香族化合物的积累，非根际土则无明显差异，说明氮沉降与植物的共同作用改变了土壤水溶性有机物结构。
- Abstract:
- To study the effects of nitrogen deposition on the functional characteristics of soil soluble nitrogen and soluble organic matter on the Loess Plateau, 6 nitrogen levels 0, 2.8, 5.6, 11.2, 22.4 and 44.8 gN/(m2·a) potted pine were set, continuous cultivation lasted for five years. Nitrogen addition significantly increased soil water soluble total nitrogen, water soluble inorganic nitrogen and water soluble organic nitrogen content, the proportion of soluble organic nitrogen to soluble nitrogen increased exponentially with the increase of nitrogen deposition. The soluble nitrogen and its components showed no obvious rhizosphere effects. At the same time, it was found that the lower and higher levels of nitrogen deposition increased the accumulation of aromatic compounds of soil water soluble organic matter in the rhizosphere, but could not make the difference in non rhizosphere soil. Nitrogen deposition can increase the content of nitrogen in soil which can be dissolved in water. The effect of plant root system on this trend is not significant. Pinus tabulaeformis can hardly change the effect of nitrogen deposition on the content of active nitrogen in soil. The combined effects of nitrogen deposition and Pinus tabulaeformis can increase the aromatic functional groups of the water soluble organic compounds in the rhizosphere.
