Abstract:In order to understand the status of salinization of facility vegetable soil,stratified
sampling of 0-40 cm soil layer was conducted in typical salinization soil of facilities vegetable producing
areas of central and southern Jiangsu Province with 10 cm as a unit,and the adjacent exposed soil
outside the greenhouse was taken as control.We determined and analyzed the soil EC value and the
vertical distribution of major salt content in the soil.The results showed that the EC value of each soil
layer and the major salt ion contents of facility vegetable soil were obviously higher than that of the CK
in the open field.NO3- was the major anion in different soil layers of this area and SO4
2- was also higher;while Ca2+ was the main cation.Soil EC value and the salt ion content were both higher in 0-10 cm soil
layer,indicating possessing topsoil accumulation for them. Soil salinization had developed to deeper
layers in some base.
