- 摘要:
- 为了探讨人工林对黄河三角洲滨海盐碱地土壤理化性质的改良效果，采用野外取样和室内分析测定相结合的方法，以林龄8年的4种人工林为研究对象，未造林空地为对照，对各样地的土壤理化性质指标进行分析。结果表明：（1）4种人工林均能改善黄河三角洲滨海盐碱地的土壤理化特性。与对照空地相比，人工林的平均土壤容重、含盐量、pH值分别降低了4.8%，44.4%，2.5%，平均总孔隙度、毛管孔隙度分别提高了6.0%，4.7%；（2）不同人工林对土壤阳离子交换性能及碱化度的影响效果各异，其碱化度大小依次为：柽柳（27.4%） > 杜梨（23.3%） > 对照（19.5%） > 白蜡（16.0%） > 盐柳（13.3%）。
- Abstract:
- In order to study the effects of different plantations on soil physicochemical properties in coastal saline of the Yellow River delta, the soil physicochemical properties of four different plantations and the control of the unplanted land were analyzed by the method of soil sampling and laboratory measurement. The results showed that:(1) the four different plantations could improve the soil physicochemical properties of coastal saline land of the Yellow River delta; compared to the control, the average soil bulk density, soil salinity and soil pH in plantations decreased by 4.8%, 44.4%, 2.5%, respectively, while the total porosity, capillary porosity increased by 6.0%, 4.7%, respectively; (2) the effect of every plantation on cation exchange performance and exchangeable sodium percentage was different, the exchangeable sodium percentages of different plantations decreased in the order:Tamarix chinensis(27.4%) > Pyrusbetulifolia(23.3%) > CK(19.5%) > Fraxinus chinensis(16.0%) > Salix psammophila ‘YanliuYihao’(13.3%).
