不同树龄桉树林下土壤斥水性研究
Study on Soil Water Repellency of Eucalyptus Forests in different Tree-age
摘要
Abstract
Soil water repellency is an important and universal physical property, which was the physical phenomenon allowing soil to repel water from soil surface particles.The experiment was conducted in 15, 10, 5 tree-age Eucalyptus forest, the surface soil layer (1～5 cm) were selected, the soil water repellency and water content were measured, and the relationships between the repellency and content were analyzed.The results showed that the soil water repellency increased significantly with the increasing of Eucalyptus treeage (P<0.05).The water repellency of soil in natural water-bearing state of Eucalyptus forest was higher than that in air-dried soil, in which the difference reached the significant level (P<0.05) in 15 and 10 tree-age Eucalyptus forest.There was a significant negative correlation between soil water repellency and water content in 5 and 10 tree-age Eucalyptus forests (P<0.05) , but no significant correlation in 15 tree-age Eucalyptus forest (P>0.05).关键词
