油松麻栎混交林土壤物理性质研究

Study on Soil Physical Properties of Mixed Pine Oak Forest

以麻标油松混交林为研究对象,油松纯林为对比,分析两种林分情况下的土壤物理性质,通过对比发现:(1)油松麻栎混交林的下层土壤紧实度更利于透水透气;油松纯林和油松麻栎混交林对比毛细孔隙度和总孔隙度在0-10cm层表现出显著差异;油松麻栎混交林的最大持水量、毛管持水量、田间持水量均大于油松纯林的持水量。可见油松麻栎混交林利于土壤结构的改善,土壤蓄水能力的增强,为辽西地区的造林任务提供可行的数据支撑。

Taking the mixed forest of oak and pine as the research object and the pure forest of pine as the contrast,the soil physical properties under the two stand conditions were analyzed.The difference of capillary porosity and total porosity between pure stands of pine and mixed stands of oak and pine was significant in 0~10cm layer.The maximum water holding capacity of pine tabulae mixed forest by capillary is all larger than that of pure pine tabulae forest.It can be seen that mixed pine oak forest is conducive to the improvement of soil structure and the enhancement of soil water storage capacity,providing feasible data support for afforestation task in western liaoning region.
