Effect of brackish water irrigation on the movement of water and salt in salinized soil

Abstract In China, fresh water resources are scarce, while brackish abundant. Reasonable utilization of is one the important measures to alleviate contradiction shortage. order study effect irrigation on and salt transport in saline-alkali soils, one-dimensional infiltration experiments soil columns were conducted. The influence with different salinities salinized was compared analyzed. results showed that under irrigation, Kostiakov model could better simulate change rate time, capacity had a positive response salinity water. There good linear relationship between cumulative wetting front distance. Under conditions, depth desalination, Na + , Cl − removal different, which inversely proportional degree salinity; increase water, content concentration increased gradually, but difference desalination zone not obvious. Therefore, has certain distribution saline soil.
