Problems solved by technology

[0006] The purpose of the present invention is to solve the problems that the grafting time of the existing bud seedling anvils is relatively fixed, the growth of the tea seedlings after grafting is relatively slow, the seedling cultivation period is long, the tea tree seeds are highly heterozygous, and the traits of the grafted seedlings may be different due to the separation of the traits of the seed stock, Provided is a method for grafting tea tree seedlings and its application

Embodiment 1

[0040] Use Zhonghuang No. 1 as the scion and Zhongcha 108 as the rootstock for grafting. The grafting steps are as follows:

[0041] 1) preparation of rootstock: rootstock selects the full-age clone container seedling with a stem diameter of more than 3 mm, prunes one week before grafting, removes the leaves and twigs below the trunk distance from the base 10 cm, retains the top 2-4 leaves, and pours enough water; details such as figure 1 As shown, the left is before the rootstock is pruned, that is, one week before grafting, the top branches of the rootstock are cut off, and the leaves and twigs below 10 cm from the main trunk are removed; One piece of leaf; the rootstock is a full-year-old tea tree clone container seedling with a stem diameter of more than 3 mm. The container seedlings can be out of the nursery in all seasons. Therefore, the grafting schedule is flexible and not subject to seasonal restrictions, and it also provides guarantees for the survival and rapid gro...

Embodiment 2

[0059] In order to explore the grafting effect between the large-leaf variety Yinghong 9 and the medium-small-leaf variety Zhongcha 108, Yinghong 9 was used as the scion and Zhongcha 108 was used as the rootstock. After 7 months of grafting, three plants were randomly selected. The seedlings are photographed, and the grafted seedlings grow as Figure 12 As shown, after 7 months of grafting, the grafted seedlings grew well, and the stems at the base of new shoots were thicker than 2mm, and the average height reached 24.32cm, reaching the standard for going out of the nursery.

Embodiment 3

[0061] In order to explore the grafting effect between the large-leaf variety Yinghong 9 and the national variety Shuchazao, Yinghong 9 was used as the scion and Shuchazao was used as the rootstock for grafting. After three months of grafting, the grafted seedlings grew as Figure 13 Shown, after grafting 3 months, grafted seedling grows way well, and scion shoot growth height has surpassed 20cm.

Abstract

The invention relates to the technical field of tea tree culture, in particular to a tea tree grafting seedling raising method and application thereof, and the method comprises the following steps: (1) preparing rootstocks and selecting proper scions; (2) cutting the rootstock; (3) cutting the scions ; (4) inserting the scions; (5) binding; and (6) managing after grafting. The method solves the problems that the existing bud stock grafting time is relatively fixed, the growth vigor of the grafted tea seedlings is relatively slow, the seedling raising period is long, the tea tree seeds are highly heterozygous, and the characters of the grafted seedlings may be different due to the separation of the characters of the seeds and the stocks.

Description

technical field [0001] The invention relates to the technical field of tea tree cultivation, in particular to a method for grafting tea tree seedlings and its application. Background technique [0002] Grafting is one of the methods of asexual reproduction of plants and is widely used in fruit tree and vegetable breeding. Grafting can not only maintain the excellent traits of scion varieties, but also utilize the favorable characteristics of rootstocks to enhance cold resistance, drought resistance, and resistance to diseases and insect pests. It has become the simplest, environment-friendly and effective technology for cultivating new varieties. . [0003] When promoting improved varieties of garden plants, asexual reproduction is generally the main method, so that the excellent traits of the varieties can be preserved to the greatest extent. At present, the breeding of improved tea tree varieties is mainly based on cuttings, and cuttings in nurseries with short ears are ...
