不同林分类型对林下土壤化学性质的影响

Effects of Different Stand Types on Soil Chemical Properties Under Forest

以辽宁北票地区的油松纯林和油松+山杏混交林为研究对象,分析两种林分类型对林下土壤化学性质的影响。结果表明:混交林对土壤p H值和有机质含量提升显著,可提高土壤质量。混交林在碱解氮和有效磷方面有较好的提升效果。

The effects of two types of plantation on chemical properties of soil under the forest were studied by using pure forest of Pinus tabuliformis and mixed forest of Pinus tabuliformis ＋ Armeniaca sibirica in Beipiao Area of Liaoning Province. Result shows that mixed forest can significantly increase p H value organic matter content of soil and therefore can significantly improve soil quality. In terms of effective nutrients,mixed forest has optimal improvement in alkalinity,nitrogen,and effective phosphorus.
