摘要
研究了刺槐与杨树混交林后沙地土壤水分 物理性质变化的状况 .结果表明 ,刺槐与杨树混交后 ,土壤水分 物理性质得到了改善 ,表现在土壤最大持水量增加 ,毛管持水量、田间持水量得以提高 ,土壤有效持水量也有了较大幅度的提高 .刺槐与杨树混交后土壤总孔隙度、非毛管孔隙度、毛管孔隙度得到提高 ,并由此而改善了混交林土壤的渗透性能 .表 4参
The changes of sandy soil water-physical properties after mixed plantation of poplar and black locust are studied. The results showed that mixed forest improved sandy soil water-physical properties, that is, increased soil maximum moisture capacity, capillary capacity and field capacity. The mixed forest also increased soil total porosity, non-capillary porosity, capillary porosity and improved soil permeating property. Tab 4, Ref 7
