Notice of Retraction: Soil Water and Soil Salt Movement on Land with Reeds Growing

Abstract

Simulation experiments were carried out in containers with groundwater supply and reeds growing. Groundwater evaporation law, the salt movement law of unsaturated soil in the 0-60cm depth, and the relationship between soil water and soil salt movement were discussed deeply. The result show: (1) Phreatic evaporation with reeds growing is larger than that on bare land under the same experimental conditions. With the increase of groundwater level, Phreatic evaporation with and without reeds growing are all decreased, evaporation with reeds decreased faster than that bare land. Evaporation from phreatic with reeds had good consistency with that from water surface. The consistency of phreatic evaporation and water surface evaporation is decreased with the increase of groundwater level. The more shallow groundwater level, the greater the amount of phreatic accumulative evaporation of soil with and without reeds growing. The relationship of phreatic accumulative evaporation and the evaporation time fit a linear function. (2) Soil salt of soil surface 0-5cm and phreatic accumulative evaporation on bare land fit a logarithmic function. The more shallow Groundwater level, the larger the slope of the cure. Soil salt of soil surface 0-5cm and phreatic accumulative evaporation on land with reed growing fit a power function. At the same phreatic accumulative evaporation, accumulation of soil salt in the soil surface is largest when the groundwater level is controlled at -40cm.
