摘要

为改善人工针叶林地的土壤化学性质退化的问题

通过土壤与枯落叶混合后进行室内培养的方法

研究了黄土残塬沟壑区阔叶树种枯落叶对针叶林地土壤化学性质的改善效应。结果表明:(1)小叶杨枯落叶对侧柏林地土壤碱解氮、有机C和胡敏素的改善效果显著;沙棘枯落叶对油松林地土壤速效磷和侧柏林地土壤pH值、速效磷、速效钾、富啡酸的改善效果显著;柠条枯落叶对油松林地土壤速效钾、有机C、胡敏酸和胡敏素的改善效果显著。(2)对油松林地来说

枯落叶的综合改善效应为:沙棘>柠条>辽东栎>小叶杨>刺槐枯落叶;对侧柏林地来说

枯落叶的综合改善效应为:小叶杨>沙棘>辽东栎>柠条>刺槐枯落叶。

Abstract

The objective of this laboratory experiment was to determine if leaf litter from deciduous tree spe-cies could be used to improve the chemical properties of a degraded soil in a coniferous forest in the gully re-gion of the Loess Plateau. Results showed that:(1) The application of Populus simonii leaf litter to a Platycladus orientalis forest soil significantly increased soil alkali-hydrolyzable N

organic C

and humin. The application of Hippophae rhamnoides leaf litter to a Pinus tabulaeformis forest soil significantly increased available P and to a Platycladus orientalis forest soil significantly increased pH value

available P

available K

and fulvic acid. The application of Caragana microphylla leaf litter to a Pinus tabulaeformis forest soil significantly increased available K

organic C

humic acid

and humin. (2) Leaf litter from Hipp-ophae rhamnoides had the greatest overall effect on Pinus tabulaeformis forest soil

followed by leaf litter from Caragana microphylla

Quercus liaotungensis

Populus simonii

and then Robinia pseudoacia. For the Platycladus orientalis forest soil

the positive effects of leaf litter declined in the order of Populus simo-nii > Hippophae rhamnoides > Quercus liaotungensis > Caragana microphylla > Robinia pseudoacia.
