Abstract

The invention relates to the field of soil science, and discloses a reconstruction structure a desertification land, which comprises a water-retaining and fertilizer-retaining layer, a mixed layer anda fertilizer layer which are sequentially laid from bottom to top, wherein the mixed layer is prepared by mixing loess and sandy soil or mixing red clay and sand soil; the water-retaining and fertilizer-retaining layer is a red clay layer or a yellow soil layer. The invention also discloses a reconstruction remediation and utilization method for the desertification land, which comprises the following steps of: selecting a sandy land with flat terrain and few vegetation and leveling the sand; laying the water-retaining and fertilizer-retaining layer and the mixed layer sequentially from the bottom to top in the sandy land after leveling, and compounding; laying the fertilizer layer on the mixed layer; carrying out multi-crop compound planting on the fertilized land; Irrigating and fertilizing: carrying out irrigation and fertilization on crops by using water and fertilizer integrated equipment. According to the invention, the desertification land is remedied through land survey, oil preparing and soil applying to create reasonable soil particles and a soil body structure, the desertification land is changed into an available land, and the land is accurately managed through soil culture fertilizer, crop optimization and irrigation and fertilization.

Description

technical field [0001] The invention relates to the field of soil science, in particular to a reconstruction structure of desertified land and a reconstruction improvement and utilization method. Background technique [0002] Healthy, ecological and efficient farmland is the basis for the development of modern agriculture. However, land improvement projects mainly focus on the transformation of low- and medium-yield fields and the construction of high-standard farmland, and the work on the improvement and utilization of degraded and unused land is relatively late. The optimization of land functions is still the main goal of land consolidation projects, and the research on the limiting factors of crop yield and related engineering measures is relatively lacking. The selection and cultivation of improved varieties is the core of modern agricultural development, but the lack of relevant cultivation techniques and land suitability research makes it difficult to sow improved var...
