Soil salt leaching device and method

The invention relates to a soil salt leaching device and method, and the device comprises a water retaining assembly which forms a to-be-leached salt region in an enclosing manner, a drainage plate islaid at the bottom of a to-be-leached salt area and makes contact with soil, a hollow structure is formed in the drainage plate so that drainage can be facilitated, and a water pumping port of the vacuum water pumping system is communicated with the drainage plate through a drainage pipeline. A vacuum technology is applied to a salt leaching process, and aiming at the characteristics of high saltcontent, high viscosity, poor water and air permeability, low organic matter content and the like of soil, a fluffy nutrient material is added into the soil firstly, an upper layer is irrigated withfresh water, then water in the soil is pumped out by vacuum, and soluble salt in the soil is eluted out through continuous supplementation of the fresh water. 本发明涉及一种土壤洗盐装置和方法，该装置包括：挡水组件，所述挡水组件围设形成待洗盐区域；排水板，所述排水板铺设于所述待洗盐区域的底部，并
