Forestry seedling cultivation fixing device

The invention relates to the technical field of seedling planting, in particular to a forestry seedling cultivation fixing device. A forestry seedling cultivation fixing device comprises a cultivation ground and a seedling body cultivated on the cultivation ground. The forestry seedling cultivation fixing device has the beneficial effects that when wind power exists outside to push a piston to slide in a mounting pipe, in the piston moving process, an annular plate rotates on all fixing plates after being stressed, and in the rotating process of the annular plate, the annular plate is fixed to the fixing plates; the cleaning plates on the annular plate are driven to break and clean weeds around the outside of the protection box, the influence of surrounding higher weeds on illumination of seedling bodies is avoided, planting operation of the seedling bodies is further facilitated, and in the piston movement process, the bottom of planting soil of the seedling bodies is pushed to be loosened, so that the plant
