不同植被条件下苏打盐渍土容重与水分入渗速率差异
Soil Bulk Density and Water Infiltration Rate under Different Vegetations in Saline-sodic Soils
摘要
Abstract
Soil bulk density and water infiltration rate were determined under different plant communities in saline -sodic soils in the Songnen Plain.The bulk density measurements showed that there was a significant difference among different vegetation covers .The lar-gest soil bulk density was found under Phragmites australis( Cav.) Trin.ex Steud.and was increased with the increase of sampling depth in soil.On the contrast,the lowest soil bulk density was observed under Leymus chinensis,which was decreased with the increase of sam-pling depth in soil.The result of water infiltration rate indicated that vegetation covers could increase water infiltration rate .The esti-mates of water infiltration rate showed a consistent agreement with the actual measured values from 0 minute to 110 minutes.关键词
