This invention provides a method for controlling Spartina alterniflora and promoting natural
mangrove restoration based on rolling mulching and in-situ mud
slurry, belonging to the field of ecological control technology. The method involves mechanically rolling Spartina alterniflora to flatten most of it and press it into the
tidal flat soil. Then, a biodegradable
mulch film is laid on top, and mud
slurry is extracted and applied to form a mud
slurry cover layer. A
mangrove seed interception and planting device is then installed on the mud slurry cover layer to prevent
mangrove seeds from growing naturally, thereby reducing the cost of Spartina alterniflora control and improving the efficiency of Spartina alterniflora control.
