Problems solved by technology

The soil column simulation device for soil solute transport is an important device for indoor soil solute research. The domestic soil solute transport simulation device is generally made of circular plexiglass or UPVC material, with a height of less than 3m and a soil column diameter of less than 40cm. The height and diameter of the test soil column are small, so it is difficult to actually simulate the migration and transformation of soil moisture and pollutants on a large scale, which brings certain difficulties to the large-scale soil solute transport simulation research. The impact of boundary effects greatly reduces the accuracy of soil column simulation. Therefore, it is necessary to develop a large-scale soil column simulation device, which also needs to achieve low land occupation, low site space requirements, and low investment. The need for large-scale solute transport simulation provides important equipment and condition support for promoting the study of soil solute transport in my country
