Effects of Simulated Nitrogen Deposition on Soluble Nitrogen in Subtropical Forest Soils

  • 摘要: 通过野外模拟试验,研究CK〔对照,0 kg/(hm2·a)〕、LN〔低氮,30 kg/(hm2·a)〕和HN〔高氮,100 kg/(hm2·a)〕处理3个氮沉降水平对亚热带针叶(杉木)和阔叶(浙江桂、罗桴栲)森林土壤中可溶性氮含量的影响. 结果表明:施氮后3 d,土壤中的w(SIN)(可溶性无机氮含量)在CK和LN处理之间差异不显著,仅发现HN处理与LN及CK处理之间的差异显著. 施氮后3个月,各处理之间差异不显著;与施氮后3 d相比,土壤中的w(NH4+ N)在CK处理显著增加了42%~68%(P<0.05),而HN处理则显著降低了45%~58%(P<0.05);土壤中的w(NO3- N)平均降低了24%~88%,其中HN处理降幅最大也最显著;杉木林土壤降幅最大. 施氮后3 d,随着施氮水平的提高土壤尤其是杉木林土壤中的w(SON)(可溶性有机氮含量)增加,其占w(TSN)(可溶性总氮含量)的比例降低.然而3个月后,施氮影响趋缓甚至相反;与施氮后3 d比较,HN处理下w(SON)降低,而其占w(TSN)的比例却有所升高,表明SON损失仍低于SIN. 阔叶天然林土壤中的w(SON)显著高于杉木人工林,表明凋落物性质差异造成的影响与w(SON)变化有关.
