Abstract:Through the supervision of the greening and beautification project of the Hanting section under the Water Diversion from Yellow River to Qingdao Project from 2021 to 2023, this paper analyzes the schemes and characteristics of the planting technology of greening seedlings in the embankment sections with high saline-alkali content. By combining and comparing the management and protection methods and the growth situations of the greening seedlings, it puts forward targeted and relatively reasonable suggestions on the seedling planting in the embankment sections with high saline-alkali content, those with relatively high saline-alkali content, and those with silt soil. It is recommended to adopt the methods of washing away salt and separating alkali, or mixing and blending with corn cob debris accounting for $5\%$ of the volume for improvement, so as to achieve the purposes of separating alkali, retaining water, and increasing soil fertility.
