Embodiment Construction
[0009] The idea of the present invention is to use the characteristics of high clay and organic matter content and low permeability coefficient of the river / lake bottom mud, and combine the current difficulties in planting plants in rocky desertification areas to make the river / lake bottom mud into spherical nutrient soil, and plant pioneer plants that can control rocky desertification. Spherical nutrient soil can be sown directly in rocky desertification areas, or sowed by hole application. Pioneer plants can use the nutrients in the nutrient soil made from bottom mud to stabilize and grow, and then through the expansion of the root system, achieve Immobilization in rocky desertification areas, so as to realize the rapid and stable growth of pioneer plants in rocky desertification areas, and promote the improvement of vegetation in rocky desertification areas.
