The grafted scion of chestnut must be picked from the tree of the fine variety. When the scion is applied on the parent tree, the outer stump of the middle and upper part of the crown should be used to avoid the emergence of the branch of the tree on the trunk of the lower part of the crown; when scioning on the grafted tree, To prevent stringing on the rootstock tree, the thickness of the scion shall be 0.5 cm or more, and the thickness of the scion shall be relaxed to 0.5 cm. The time taken should be before the chestnut sprouts, generally before the Ching Ming. The scion to be laid must be bundled in a timely manner, with 100 bundles each, and the base must be flush. It cannot be placed in the orchard for too long. It can be wrapped in sacks, transported in time to the storage pits, and placed on the floor of the cellar, about 10 cm thick. The clean river sand will be bundled with scion and inserted in the wet sand. It should also be checked frequently to prevent the scion from becoming moldy, germinating and draining. During the day, the ventilation of the cellar door should be opened and the cover should be tight at night. When the cellar is dry, water should be sprayed in time so that the quality of the scion can be guaranteed and the grafting period can be extended.
