Method for grafting saving of camellia tree plant with dead overground branches

Abstract

The invention discloses a method for grafting saving of a camellia tree plant with dead overground branches. The method for grafting saving of the camellia tree plant with the dead overground branches comprises the following steps that a camellia tree of which the overgroud stem is dead due to pest and disease damage or environment factors is selected, the dead stem is cut off and removed with a saw, the underground root portion with the physiological activity is left, a notch is cut to be in a deep V shape along the axis of the root, a branch, with a thickness matched with the thickness of the notch in the root portion, of a precious camellia tree is used as a grafting scion wood, 2-5 twigs can be left on the morphological upper end of the branch, the morphological lower end of the branch grafting scion wood is cut to be in a shape matched with the shape of the notch in the underground root portion, the branch grafting scion wood is inserted into the notch in the underground root portion, the cambium and the phloem of the grafting scion wood are aligned with the cambium and the phloem of the root, sealing treatment is carried out, the grafting condition is checked at regular intervals, a plastic film is taken out of the root portion after two months, and the grafting survival condition and the sprouting condition of the scion wood are checked. According to the method for grafting saving of the camellia tree plant with the dead overground branches, the branch of other camellia trees is used as the scion wood based on the original root portion, and the dying camellia tree can survive with the grafting method.

Description

technical field [0001] The invention relates to a method for maintaining garden trees, in particular to a method for grafting and rescuing dead aboveground branches of camellia trees.

[0003] Camellia trees are often affected by some diseases and insect pests or environmental factors during the growth process. Especially during the transplanting process, the above-ground parts often die, while most of the bottom parts are still physiologically active for a considerable period of time. In general gardening practice , these dead plants on the ground will be discarded and replanted, which will often cause greater economic losses
