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.

This invention discloses a mangrove ecological restoration planting system with survival status monitoring. The system includes a portable integrated planting device, a survival status monitoring module, and a positioning and tracking module. The planting device includes a cylindrical body with a pointed bottom. Inside the cylindrical body, from top to bottom, there are a nutrient chamber and a seedling fixation device. The side wall has an expandable anchoring structure to improve the device's erosion resistance. The nutrient chamber is filled with slow-release fertilizer and in-situ soil probiotic immobilization substrate to provide a long-term and stable nutrient supply for mangrove seedlings. The seedling fixation device is made of biodegradable elastic material to fix the seedling roots. The survival status monitoring module monitors the growth of seedlings along the axial direction of the cylindrical body in real time and determines the survival status through elastic tension components and tension sensing units. The positioning and tracking module obtains the device's location information to count the proportion of devices washed away by tides, providing data for optimizing the anchoring structure.
