salt concentration in soil

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。

The research, turf planting experiment in small areas, has been carried out with six varieties of Bluegrass (Poa) under heavier soil salinity (The average soil salt concentration is 0.617%).

选用早熟禾属的6个品种在较重盐渍土地上（平均土壤全盐量0．617％）进行小区植坪试验。
