Study on the Slope Protection Effect of Different Vegetation Types in Ditch and Land Reclamation

This article focuses on improving the effectiveness of slope protection and proposes a series of effective strategies. In terms of vegetation selection, based on local natural conditions, drought tolerant vegetation such as lemon and sea buckthorn are selected in arid areas, rhododendrons and tea trees are selected in acidic soil areas, and Robinia pseudoacacia and Lespedeza are selected in steep slopes, emphasizing the synergistic combination of trees, shrubs, and grasses. In terms of configuration mode, a layered configuration is adopted, with tall trees such as poplar and willow planted on the upper layer, shrubs such as purple locust and thorns planted on the middle layer, and herbaceous plants such as ryegrass and clover planted on the lower layer. Mixed planting of leguminous and non leguminous plants is also promoted to increase vegetation diversity. In the later maintenance and management, reasonable irrigation and fertilization should be carried out according to vegetation needs and soil moisture conditions. Drip irrigation and sprinkler irrigation should be used to ensure water in dry seasons, organic fertilizer should be applied in spring and autumn, and chemical fertilizer should be applied during vigorous growth periods; At the same time, the comprehensive use of biological, physical, and chemical methods to prevent and control pests and diseases, regular inspections, and ensure the effectiveness of slope protection provide scientific guidance for slope protection projects.
