Yangmei saplings grafting have tips (Yangmei tree grafting skills)

Yangmei saplings are generally used branching, mainly cutting. The scion selection of strong growth, into the fruitful fruitful tree, cut the upper periphery of the crown of l a 2-year-old branch. Rootstock selection of wild sowing seedlings or from sowing trees to take seed sowing, cultivate 2 a 3 years after the sapling.

Yangmei grafting in the spring before budding, early connection is more favorable, too late due to injuries to the sulfur impact interface survival, generally in early February to late March. Each scion is 6 to 7 centimeters long, with plastic film wrapped after picking up, the best mulch moisturizing.

Yangmei sap flow is exuberant, affecting the grafting survival rate, especially in the large rootstock grafting, the impact is greater. In order to inhibit the tree's momentum and reduce the rise of sap in the roots, the following methods can be used for treatment.

1, in situ grafting, cut off the root system. Commonly used in 2 a 3-year-old rootstock, after grafting from the rootstock cultivation beds on both sides of the deep cut, cut off part of the main lateral roots.

2, ex situ grafting. Before grafting, dig up the rootstock, cut off some of the main lateral branches, planted in a different place, and then grafted.

3, indoor grafting. The rootstock will be dug up, indoor grafting, used for 2-3-year-old rootstock, or from the mountain field excavation of 3-4-year-old large rootstock, after picking up the fake planting or directly planted in the planting point.

4, stay branch grafting. First planting rootstock, and then in situ grafting, the application of large rootstocks more. That is, grafting on the main branch, leaving another branch for the "hanging branch" to attract water to the branch flow, slowing down the growth potential of the grafted part, in order to improve the grafting survival rate.
