High concentration of salt in soil causes ion imbalance, oxidative damage, water deficit and nutrient deficiency, which lead to molecular damage, growth retarded, and even death of plant.

土壤中高浓度的盐分会使离子失衡、氧化伤害、水分亏缺、营养缺乏，并导致生物大分子被破坏、生长迟缓、甚至植株死亡。

Soil hydraulic conductivity is closely related to the movement of water and salts in soil profiles and is highly affected by solution salt concentration and its composition.

水力传导度的变化直接影响土壤剖面的水盐运动，并和土壤溶液的盐分浓度及其组成有很大关系。
