| 摘 要： | 为了比较山地麻竹笋用林不同土壤垦复措施对养分流失动态的影响,在福建南靖国有林场设置径流场,进行了1年的观测、取样和氮磷钾浓度分析.结果表明,3种土壤垦复措施的氮、磷、钾流失量具有明显的季节性,4～9月3种养分流失量占全年90%以上,且都呈现全翻>带翻>对照,但3种经营措施间氮、磷的年流失量差异均不显著,全翻的钾流失量差异水平达显著,带翻与对照间差异不显著.

| Abstract: | A comparative study on the soil nutrient losses of hilly land shoot-used Dendrocalamus latiflorus plantations at the Nanjing stated-owned forest farm,Fujian Province showed that the losses of soil N,P and K under three treatments of stand condition improvement varied with season,and 90% or more of these losses appeared from April to September,with the order of overall ploughing>strip ploughing>control. There was no significant difference of N and P losses among the three treatments,while the K loss was markedly higher under overall ploughing than the control. |
