Method for breeding high-yield fast-growing seedlings of high-odor phoenix single-clump tea

Abstract

The invention relates to a method for breeding high-yield fast-growing seedlings of high-odor phoenix single-clump tea. The method for breeding the high-yield fast-growing seedlings of the high-odor phoenix single-clump tea comprises the steps: selecting and breeding root stock seedlings, transplanting, cultivating and disposing the root stock seedlings, selecting and disposing scions, grafting on the lower portion under the skin of the scions, keeping wet and keeping warm by sleeve covers, carrying out shading, shearing bags, removing covers and removing binds, pinching, keeping loose and the like. According to the method for breeding the high-yield fast-growing seedlings of the high-odor phoenix single-clump tea, tea seeds of a phoenix narcissus variety are selected and used for being cultivated to form the root stack seedlings, then half-lignification robust branch tips of phoenix single-clump brand-name and high-quality old tea trees serve as the scions to be grated to the root stack seedlings, not only can new seedlings of tea trees be bred rapidly, but also yield is high, quality is good, and excellent properties of the phoenix single-clump brand-name and high-quality old tea trees are completely kept after the bred new seedlings are put into production. The method for breeding the high-yield fast-growing seedlings of the high-odor phoenix single-clump tea is a tea-tree seedling method which has popularizing significances.

Description

technical field [0001] The invention relates to the technical field of tea seedling breeding, in particular to a method for breeding high-yield and fast-growing seedlings of high-aroma Phoenix single-clump tea. Background technique [0002] Fenghuang Dancong tea refers to the excellent single plant selected from the Fenghuang Narcissus variety under the natural conditions of Fenghuang Mountain in Chaoan County, Guangdong Province, as well as the varieties, strains and strains cultivated. Oolong tea is harvested by unique processing techniques such as greening→drying green→making green (including greening, shaking and standing)→cracking→twisting→drying. It has a variety of natural floral / fruity aromas and special flavors. , belonging to semi-fermented tea, is one of the six famous teas in the country. Fenghuang Dancong tea has the characteristics of clear yellow and bright soup, obvious natural flower fragrance, strong honey flavor, obvious mountain charm, mellow and fresh t...

Problems solved by technology

Among them, seedling cultivation is the use of tea tree seeds to form tea seedlings through sowing and cultivation, which belongs to sexual reproduction. The tea seedlings cultivated by this method are difficult to fully inherit the excellent traits of the mother tree due to genetic factors, so they cannot completely maintain the fragrance of famous and high-quality old tea trees. type and quality, and this method has the limitation of long seedling cultivation cycle; tea branch cutting seedling cultivation is to select a small section of mature new shoots of tea trees and insert them into the soil to grow and cultivate them into complete new seedlings, which belongs to asexual reproduction. Although this method can maintain the mother tree’s Excellent traits, but there are limitations of low cutting survival rate and seedling circumference. Grafting seedlings is to select famous tea tree semi-lignified branches and graft them to tea tree rootstocks to form new seedlings. This method can also maintain the excellent traits of the mother tree. However, there are limitations of cumbersome transplantation of new seedlings, long seedling cultivation cycle, and low yield of new seedlings

[0004] The publication number is CN 10257784A, and the invention patent application with the publication date of July 18, 2012 discloses a tea tree root stock grafting and breeding method. The method uses the root stock of sowing tea seedlings as the root stock, and takes the semi-woody tea tree seedlings that year. Wooden or lignified branches, cut into short ears and grafted with rootstocks, the grafted joints were tightly wrapped with aluminum foil tape, and planted in the nursery. This method has a survival rate of more than 90% of grafted seedlings, and large-scale seedlings can be raised, but there is also a seedling cycle Longer, the limitation of low yield after the seedlings are put into production
