不同人工林对黄河三角洲滨海盐碱地土壤理化性质的影响
Effect of Different Plantations on Soil Physicochemical Properties in Coastal Saline Land of the Yellow River Delta
摘要
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 cat ionexchange 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 ％).关键词
