Effects of Litter Removal and Nitrogen Addition on Nitrogen Dynamics in Chinese Fir and Broad-Leaved Forest Soil

  • 摘要: 通过野外模拟试验,选择中亚热带针叶林(杉木林)和阔叶林(浙江桂林和罗浮栲林)森林生态系统,设3个施氮水平CK(对照)、低氮〔30kg/(hm2·a) 〕和高氮〔100kg/(hm2·a)〕及2个凋落物处理,研究施氮对土壤主要形态氮质量分数的影响、动态变化及凋落物在其中的作用. 结果表明:与CK相比,高氮处理可瞬时(3d)提高森林土壤氮质量分数,但施氮后持续效应的影响降低. 与保留凋落物相比,去除凋落物在施氮的持续效应中,可降低阔叶林土壤w(铵态氮)18.2%,而杉木林土壤的氮质量分数则略有升高.去除凋落物下施氮的持续和瞬时效应可增加各种林下土壤的w(硝态氮),其中浙江桂林土壤w(硝态氮)分别增加58.9%和38.2%,罗浮栲林土壤分别增加7.0%和30.0%,杉木林土壤分别增加-17.1%和9.0%. 可见凋落物在施氮连续事件中存在复杂的短期和长期相互影响. 阔叶林土壤w(SON)(SON为可溶性有机氮)较高,并且其微生物w(SON)及其占微生物w(TN)的比例高于杉木林土壤,而杉木林土壤微生物w(铵态氮)及其占微生物w(TN)的比例高于阔叶林土壤.
