Abstract
The application discloses a method for clearing and controlling recurrence of Spartina alterniflora, which comprises the following steps: firstly, arranging straw stacking fields and landfill pit positions in a Spartina alterniflora clearing area; secondly, mowing, recycling and airing the aboveground part of the Spartina alterniflora before a flowering period; thirdly, excavating the landfill pits according to the terrain, pushing the surface soil containing seeds and residual roots into the landfill pits, covering and compacting the soil, and further performing rotary tillage on the root dense positions to break the roots; and finally, restoring the beach by using the excavated deep earthwork or external planting soil, and planting native vegetation after the terrain is stable. The application mainly utilizes mechanical equipment, is simple and easy to implement, can form a strong interference habitat for the Spartina alterniflora, effectively solves the problem of recurrence of the Spartina alterniflora, and improves the success rate of plant replacement.
