Greenhouse soils displayed apparent phenomena of salt accumulation in topsoil (0–20cm) and salt leaching downwards to the bottom of the soil (80–100cm), especially NO3- that seriously affected the quality of groundwater in the area. Apart from HCO3-, the contents of NO3-、SO42、Cl-、Ca2+、Mg2+、K+、Na+ were increased to different degree in greenhouse soils, and NO3-、SO42- and Ca2+ were the major ions in the soils.

此外，盐分离子的大量累积和向底层迁移，特别是NO3-的淋溶已严重影响到部分地区的地下水水质。4）设施栽培后，土壤中的NO3-、SO42-、Cl-、Ca2+、Mg2+、K+、Na+均有不同程度的累积，阴离子以NO3-和SO42-为主，阳离子以Ca2+为主。

According to the law of conservation of mass and the law of Nsimultaneous equilibrium, the mathematics model of Ni -NH3-NH4 -C2O42-H2O thermodynamic equilibrium system was first built, and the corresponding logarithms concentration -pH diagrams of the system were also drawn.
