Wax-sealing grafting method for old branches of daye tea tree

Abstract

The invention provides a wax-sealing grafting method for old branches of a daye tea tree. A grafting period is selected to be from an overwintering budding period of the tea tree to an initial periodof budding. The method comprises the steps: scion branch selection, scion branch collection, scion scissoring, scion waxing, selection of seedling rootstocks, scion cutting, cutting of rootstocks, scion insertion and interface sealing and binding. According to the technical scheme provided by the invention, on the one hand, the method employs a side cutting mixed grafting method of blending the side grafting and cutting grafting, thereby solving a problem that a conventional grafting method is low in rate of survival because the grafting is liable to cause water loss or waterlogging; on the other hand, the method achieves the grafting with the seedling rootstocks of the daye tea tree through collecting a few of new types of daye tea trees or the branches of new types of trees, and then achieves the culturing of a high-yield crown through the elaborate culture management of a tea garden, thereby speeding up the production of the new type of tea gardens or the expansion of the new typesof resources, achieving the purposes of yearly grafting and next year production, and achieving the efficient and quick expansion of the new type of daye tea trees or the new types of resources.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a wax grafting method for old branches of large-leaved tea trees. Background technique [0002] The reproduction of the offspring of the big-leaf tea tree is divided into two ways: sexual reproduction and asexual reproduction. Vegetative propagation methods usually adopt methods such as cuttings, layering, grafting, and tissue culture to cultivate new tea tree plants. In the Yunnan tea area, the breeding and promotion of tea tree varieties is usually achieved by using short-ear cuttings to propagate seedlings and transplanting them. Using the grafting method to renew the large-leaf tea tree varieties has been tried by scientific researchers in the 1980s and 1990s, but it has not been popularized due to the old grafting method, low survival rate, and high cost. [0003] Due to the severe drought in winter and spring in Yunnan tea area, the survival rate of ...

Problems solved by technology

Using the grafting method to update the large-leaf tea tree varieties has been tried by researchers in the 1980s and 1990s, but it has not been popularized due to the old grafting method, low survival rate, and high cost.

[0003] Due to the severe drought in winter and spring in Yunnan tea area, the survival rate of transplanted short-eared cutting seedlings is generally low. Repeated replanting not only increases the cost of garden construction, but also delays the production time of tea gardens. The low survival rate of planting is the bottleneck restricting the popularization of fine varieties of large-leaf tea trees in Yunnan
