Response Characteristic of Soil Moisture and Salt to Salt Isolated Layer in Seashore Saline Soil
Research of soil salt and water movement rules is the premise and foundation of the construction of vegetation in seashore saline-alkali land. 20cm slag was set as salt isolated layer in the bottom of plant pit to study the rule of seasonal variation of soil profile salt and water. The result indicates that:(1) salt isolated layer not only can reduce the changes of soil moisture content at different depth significantly, and make it to be stable, but also has obvious effect to maintain the consistency of soil moisture, this is beneficial to the survival and growth of saline-alkali plants (2) salt isolated layer makes the changes of electrical conductivity relative alleviation at different soil depths, slowly increase, lesser range, even it inhibit the salt movement in dry season. This paper shows that the setting of salt isolated layer can adjust water and salt in saline-alkali soil, improve the survival rate and growth of saline-alkali plants.
