研究了马尾松与山杜英、枫香、拟赤杨和光皮桦混交后土壤水分物理性质的变化。结果表明:采用几种阔叶树与马尾松混交后,改善了土壤的水分物理性质,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。阔叶树与马尾松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。
The changes of soil water physical properties after mixed with Pinus massoniana and Shanmuying, Liquidambar formosana, Alnus cremastogyne and Betula platyphylla were studied. The results showed that the physical properties of the soil were improved after the mixed use of several broadleaf trees and Pinus massoniana. The results showed that the maximum water holding capacity increased, the capillary water holding capacity, the field water holding capacity increased and the soil effective water holding capacity also increased greatly . The total soil porosity, non-capillary porosity and capillary porosity were increased after mixed with broad-leaved tree and masson pine, and the permeability of mixed soil was improved.
