同林龄不同林型土壤交换性阳离子含量的比较分析

Comparison Analysis of Exchangeable Cation Content of Soil of Different Forest Type in the Same Stand Age

通过对二代落叶松幼龄林、樟子松幼龄林、天然次生林、落叶松水曲柳混交林土壤交换性阳离子的分析,得到了同林龄土壤交换性阳离子变化趋势,为评价土壤供肥蓄肥能力、改良土壤和合理利用林地、营造速生丰产林提供重要依据.

By analysis of exchangeable cation content of soil of secondary young growth of larch, young growth of Pinua sylvestris vat. mongolica, natural secondary forest mixed forest of larix and Fraxinus mandshurica, variable trends of exchangeable cation content of soil of same stand age were obtained, providing important reference for evaluating fertilizer application or storage of soil, improving the soil, using the stand conservatively and establishing the fast-growing and high-yielding plantation.
