1. beech has straight trunk, dense shade and dense crown. In the process of tree cultivation, the natural form should be maintained. Modeling method: natural multi-branch modeling. Plastic pruning and technical planting pruning: when planting annual seedlings, attention should be paid to protecting fibrous roots and properly pruning root systems. Sowing time should be from the end of 10 to the end of February 165438+ before germination. Root cutting: generally, the main root is 3-5cm and the lateral root is 3-6cm. Try to keep the fibrous roots and cut off the injured roots and diseased roots. The incision must be smooth, not rough. Pruning of branches and leaves: In order to reduce the transpiration of water, maintain the water balance between the above-ground and underground parts, and improve the survival rate of transplantation, branches and leaves must be pruned appropriately.

2. The top advantage of beech trunk should be maintained, not "big head". False bifurcation mostly occurs at the top of the trunk, so a branch should be cut off from the base in time to keep the trunk straight and the top advantage. For seedlings with damaged main branches, select the solid branch closest to the trunk as the trunk, and cut off other side branches appropriately; Secondly, cut off thin and weak branches from the trunk, and the incision should be smooth, and cut off all the main branches of 1/2. Pruning of seedlings: pruning of seedlings, keeping proper branch points and full crowns.
