The results indicated that: at the beginning of experiment with the exposed sediment treatment,several forms of nitrogen released from the sediment,perhaps disturbed by planting submerged macrophyte,but with the time passing,submerged macrophyte absorbed more NO-3-N,and through the nitrification and denitrifi.
结果表明,开始阶段因裸露底泥处理会向水体中释放出不同形态的氮素,使水体总氮含量有所增加。
