- Available N and P have inverse dynamics in that while available N decreases, available P increases, except for Phragmites communis Trin. 根际土有效态养分的变化则与全态相反，6种植物的根际土有效氮含量均显著低于非根际土，除芦苇外，根际土有效磷含量均高于非根际土。
- The results were found as following: wetland with plants was superior to unplanted one in removing ability of both N and P. 结果表明:有植物床的脱氮除磷效果好于无植物床,复合床脱氮除磷效果最好,但芦苇床、姜花床、复合床之间的差异不显著;
- The matter reason of eutropher in water is because algae grow raplily in propriety temperature and illumination when nutriment of N and P is imported from the environment. 水体富营养化的主要原因是由于外界输入过量的氮磷营养物质,在适当的温度、光照下,藻类过量生长繁殖造成的。
- Elevated CO2 increased the dry mass of stem, branch, leaf and root and the uptake of N and P per plant, but decreased the N and P contents of each organ. CO2浓度增加,红桦幼苗茎枝、叶、根和总生物量提高,氮(N)、磷(P)含量降低,但单株N、P总吸收量均增加。
