| 摘 要： | 在黄河三角洲地区进行的一系列造林抑制土壤返盐的试验表明:林分郁闭度与抑盐作用正相关;林木对其一定范围内的土壤有抑盐作用;农田林网对抑制土壤返盐有显著作用.在此基础上,探讨了林木抑制土壤返盐的原因.提出在黄河三角洲地区广泛造林,同时配合良好的水利建设,是抑制土壤返盐,延长土地利用时间的有效措施.

| Abstract: | A series of forestation tests for controlling soil secondary salinization were conducted in the Yellow River Delta Saline lands.The results showed that the stand canopy density had a positive correlation to the control of soil salinization and forest trees played the control role on soil salinization within a certain range.The farmland shelterbelts had a significant effect on soil salinization control.On the basis,this paper explored the causes of controlling soil secondary salinization by forest trees and ... |
