Research on the Core Technology of Remixing Soil by Soft Rock and Sand in the Maowusu Sand Land Region

Abstract

The purpose of this paper is to resolve the technique problem of land consolidation in Maowusu Sand Land to make the sand land into important reserve resources for farmland development aiming to execute the land consolidation in Maowusu Sand Land by the material of soft rock and sand which are called two calamities together.Methods employed include laboratory experiment,field experiment and empirical analysis.The results indicate: 1) The complementarity of properties in material structure is first found,and the composition ratios by soft rock to sand fit for different crops are obtained;2) The model of effective utilization of water and soil coupling in ecological fragile region is proposed;3) The technique system of remixed soil by soft rock and sand is completely researched;4) Standardized and sweeping land consolidation project is innovatively operated,which realizes utilization of sand land successfully, and a new model of land consolidation integrating the construction of water-saving efficient and high-standard farmland with modern operation is made out.It is concluded that resourceful utilization of soft rock and sand could be realized with scientific ratio by soft rock to sand to make the desert into farmland,which supplies technical support for comprehensive development of Maosuwu Sand Land.
