| 摘 要： | 以阜新地区油松和樟子松混交林和油松纯林的林下土壤为研究对象,通过研究不同林分下对土壤一些物理性质的变化,探讨不同林分对土壤的影响。结果表明:在土壤颗粒组成上,混交林各层土壤的黏粒含量均高于纯林;在土壤团聚体所占比例上,混交林0.25mm团聚体比例高于纯林。混交林较纯林具有改善土壤质地和结构的作用。

Effects of Different Stand Composition on Soil Physical Properties |

| Abstract: | Taking understory soil of Pinus tabuliformis and Pinus sylvestris var.mongolica in Fuxin region as re-search obj ects,through studying the changes of different stand on physical properties ,the features of cultivation in local mixed forest were discussed.Result shows that:in the soil particles,clay content of each layer of soil in mixed forest is higher than that of pure stand.In the proportion of soil aggregates,mixed forest > 0.25 mm aggregates is higher than that in the pure stand.So the mixed forest have the features of improving the soil texture and structure than that of the pure forest. |
