In the rapid urbanization process, each construction occupies high-quality cultivated land, and regional tillage returning forest engineering is implemented, so that new problems of reduction of per capita cultivated land, lack of land and grain and the like are caused, and the occupation and compensation balance of the cultivated land is required. Therefore, comprehensive remediation and utilization of degraded and unutilized land is critical. The Maousu sand land is one of four sand lands in China, has proper natural conditions and has great potential for treatment and utilization. However, most of the past land improvement methods concentrate on sand prevention and sand fixation, and the problem of 'three-way' of water running, fertilizer running and soil running of the sandy land is not fundamentally solved, so that the degenerated sandy land is stably transformed into a production type newly-increased cultivated land, and the goals of ecological conservation and green agricultural development are simultaneously realized. Secondly, the partial renovation technology has high cost, slow effect and poor persistence. Therefore, starting from the structural problem of the sandy land, the method fundamentally solves the problems of loose texture of the sandy land, poor structural stability of the soil body and the like by engineering construction measures by utilizing the complementarity of other soil materials around the sandy land, and becomes the key for the regulation and utilization of the desertified land. Although a water and soil coupling test facility for the field building by compounding arsenic sandstone and sand is reported, the reconstruction of a soil layer of a sand ground is not considered, and the bottom sand soil still has the risk of water and fertilizer running.

In the elm forest city in the south of the roughur sand land, the domestic desertification land and the clay are alternately or vertically superposed and distributed, so how to utilize the complementarity of the clay and the sand around the sand on the physical structure to build the soil body of the sand land, form a reasonable particle structure and a reasonable soil layer structure, thoroughly solve the utilization obstacle of the sand land and promote the productivity of new land building is a problem to be solved urgently.

According to the crop planting requirement, sandy soil with different thicknesses is covered on the crushed clay, the thickness of the sandy soil is 30cm, but the volume ratio of the sandy soil to the clay in the mixed layer 1 is generally required to be ensured to be 1:1, namely the plowing thickness is generally twice of the thickness of the sandy soil. The plowing depth of the covering layer in the mixing step was 30cm, the sandy soil of 15cm thickness and the pulverized clay of 15cm thickness were mixed to form a mixed layer 1, and a clay layer 2 of 15cm was left. The clay layer 2 is used as a water and fertilizer retaining layer, and the mixed layer 1 and the clay layer 2 form a 'montmorillonite soil' which is 'sticky in sand'. Ploughing for 2-3 times to mix the covering sand and clay uniformly and reconstruct soil particles to form surface soil with reasonable structure. The technical scheme utilizes the complementarity of the clay and the sandy soil around the sandy land on the physical structure to reconstruct the sandy land soil body, forms a reasonable particle structure and a reasonable soil layer structure, thoroughly solves the utilization obstacle of the sandy land and improves the productivity of the sandy land.
