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.
