Embodiment 1

[0069] 1. Reed collection: reeds are collected from the natural growth of reed communities;

[0070] Select reeds that grow well at the collection site and cut them off the ground, and cut off the reed leaves, then sort the thin rods: 2-3 mm in diameter, thick rods: 3-5 mm in diameter, and cut the thick and thin reed rods respectively into 30 cm long;

[0071] 2. Germination of reeds: germination under bundled conditions;

[0072] Bundle 10 thin reed stalks into 1 bundle or 5 thick reed stalks into 1 bundle, put them into the pool for soaking for 15 days; during this period, change the water once every 3 days to make the reed stalks germinate and cultivate reed seedlings;

[0073] 3. Seedlings of reeds

[0074] Cut the newly germinated reed seedlings on the reed stalks, plant them in rectangular plastic boxes filled with peat soil that are convenient for transportation, and cultivate them for 55 days. The rectangular plastic boxes are 35 cm long, 25 cm wide, and 10 cm high; ...

Embodiment 2

[0078] 1. Reed collection: reeds are collected from the natural growth of reed communities;

[0079] Select reeds that grow well at the collection site and cut them off the ground, and cut off the reed leaves, then sort the thin rods: 2-3 mm in diameter, thick rods: 3-5 mm in diameter, and cut the thick and thin reed rods respectively into 30 cm long;

[0080] 2. Germination of reeds: germination under bundled conditions;

[0081] Bundle 10 thin reed stalks into 1 bundle or 5 thick reed stalks into 1 bundle, put them into the pool for soaking for 15 days; during this period, change the water every 4 days to make the reed stalks germinate and cultivate reed seedlings;

[0082] 3. Seedlings of reeds

[0083] Cut the newly germinated reed seedlings on the reed stalks, plant them in a rectangular plastic box filled with peat soil that is convenient for transportation, and cultivate them for 60 days. The rectangular plastic box is 38 cm long, 27 cm wide, and 11 cm high; Water once...

Abstract

An engineering method for restoring the degenerated river bank by reed includes such steps as culturing reed seedlings, and transplanting them in the slope of river bank by different engineering approaches.

Description

technical field [0001] The invention belongs to an engineering method for restoring reed communities to degraded river bank ecosystems. Background technique [0002] Based on traditional water conservancy engineering design ideas, the revetment works of urban rivers in my country only consider the durability of the project and the convenience of construction, and mostly use concrete or reinforced concrete materials, ignoring that rivers are also living ecosystems. As a result, artificial structures are cut off. The connection between the water ecosystem and the terrestrial ecosystem destroys various ecological processes of the river, which leads to the reduction of the self-purification and self-recovery ability of the river and the serious pollution of the river. [0003] Since the 1970s, developed countries such as Germany, Switzerland, and Japan have carried out a large number of experimental studies on the ecological restoration of concrete riverbanks, rebuilt concrete ri...
