Problems solved by technology

The above two methods have the following disadvantages in the breeding of wild tea tree seedlings: (1) wild tea trees grow in deep mountains, and there is a transportation process from picking branches to cuttings. The length of fresh-keeping time of tea tree cuttings directly affects the survival of tea seedlings cuttings. rate, but there is no branch fresh-keeping method in the above patented technology
(2) wild tea is undomesticated tea tree, its breeding technology is different from cultivated tea tree, and the cutting survival rate is low; and there is no research in the existing patent
[0004] The application of the prior art on wild tea has the following disadvantages: when the seedlings are propagated and cut, a complete leaf is left, and the water on the leaf surface has a large transpiration effect, which affects survival; Long time, easy to get sick, low survival rate
[0005] In view of the disadvantages of no tea tree branch fresh-keeping technology, low survival rate of wild tea seedlings and easy disease in the existing technology, it is necessary to provide a new breeding method of wild tea seedlings to improve the survival rate of wild tea cuttings and the utilization rate of branches

Abstract

The invention provides a breeding method for wild tea nursery stocks and belongs to the technical field of plant cultivation. The method comprises the steps of (1) nursery land selection; (2) seedbed building; (3) sunshading shelter erecting; (4) scion harvesting and freshness preservation; (5) scion cutting; (6) seedling scion insertion; (7) film mulching and heat preservation; (8) nursery garden management. Compared with the conventional wild tea cutting technology, the breeding method increases the utilization rate of scions, shortens the growth cycle of tea seedlings and increases the survival rate of nursery stocks, with survival rate of the wild tea nursery stock cutting reaching 85%-90%.

Description

technical field [0001] The invention relates to a method for breeding wild tea seedlings, belonging to the technical field of plant cultivation. Background technique [0002] China is the origin of tea trees and has rich resources of wild tea tree varieties. The breeding and preservation of wild tea trees is of great value and significance to the utilization of these tea tree variety resources, tea tree germplasm innovation, variety selection and tea tree biotechnology research. [0003] At present, there are few researches on the special technology of wild tea seedling breeding, and the technology related to the cutting breeding of tea tree seedlings is mostly used. Chinese Invention Patent Application Publication No. CN 104604506 A "A Rapid Breeding Technology of Ancient Tea Trees" discloses a method for rapid breeding of ancient tea trees, which includes "selection of nursery sites - establishment of seedbeds - setting up shade sheds - cuttings of spikes - Nursery manage...
