| 摘 要： | 通过室内培养的方法代替实地混交造林和枯落叶客置实验,研究了陕北黄土高原不同阔叶树种枯落叶对针叶纯林土壤微生物数量的影响。结果表明:在陕北半干旱风沙区(靖边),油松林引入白榆,樟子松林引入旱柳或客置其枯落叶,有利于改善土壤微生物性质;在陕北半湿润黄土丘陵区(黄陵),侧柏林引入桦树,落叶松林引入刺槐、小叶杨、桦树和辽东栎,油松林引入桦树、小叶杨和刺槐或客置其枯落叶,有利于改善土壤微生物性质。

| Abstract: | Impacts of different dry deciduous of broad-leaved species on soil microbial of artificial coniferous pure stands in Loess Plateau of Northern Shaanxi Province were investigated.The results showed that the introduction of Ulmus pumila to Pinus tabulaeformis forest and Salix matsudana to Pinus svlvestris forest could improve microorganisms in the soil in this semi-arid and sandy area(Jingbian).In the semi-humid zone(Huangling) however,soil microorganisms could be improved by the introduction of Betula platyp... |
