Salt Ions Content and Its Vertical Distribution in Salinization of Facility Vegetable Soil in Central and Southern Jiangsu Province
摘要
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 SO42-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.关键词
