Example Embodiment
[0015] Example 1
[0016] Such as figure 1 As shown, in the quasi-ecological lake bank slope constructed by the present invention, the embankment adopts a combination of embankment and road, the embankment body is a homogeneous earth dam, and the construction of the bank protection is located above the pavement of the river bed. The trenches excavated on the slope are grid-like, with a width of 30cm-40cm and a depth of 25cm-30cm. For sandy soil slopes, the area within the frame formed by the ditches is 3m 2 ~4m 2 , For the slope of clay soil, the area can be appropriately increased to 5m 2 ~6m 2 . Such as image 3 As shown, high-density root systems are used to plant wet plants such as willow and tamarisk in each ditch. The plants are planted by transplanting. We take 60cm-80cm wet plants and cut them to a height of 50cm. The plant spacing is 2.5cm-3.0cm, the roots are interlaced and planted in the ditch, covered with soil, watered enough, and watered again the next day. After the...
Example Embodiment
[0017] Example 2
[0018] Such as figure 2 As shown, the trench excavated on the slope in this embodiment is fish-scale, and wet plants such as chinensis and tamarisk are planted by cuttings in the trench. The plant spacing of the wet plants is 1.5cm—2.0cm, and the cuttings are 30cm long, and are inserted into the soil. 20cm. The cutting date is March 10-20, the south of the Yangtze River can be advanced appropriately (March 10), and the north of the Yangtze River can be postponed appropriately (March 20). Plant high-density wet plants in the ditch, cover with soil, water enough water, and water again the next day. After the water penetrates into the soil layer, cover with soil as a ridge, the ridge height is 20cm--30cm. Cut it once in the autumn of the first year. During the 15th-20th of August, lightly cut it 30cm-35cm above the ground. After the first year, it can be cut twice a year, early spring on March 10-15 or at the turn of autumn and winter on November 15-30, re-cut to ...
