When the grafted seedlings grow to 20 centimeters in length, loosen the plastic tape in time and wrap the plastic tape loosely and wrap it in the original direction.
Second, timely support
When the scion grows to 30 centimeters, 40 to 50 centimeters of sticks are used to tie them. When tying, first stick the stick with the original branch branches 2-3 fixed, and then the branch and small sticks branching 2-3 sections tied to help, with the grafted branches to be continued growth, support work needs to be kept in phases to keep up In addition, for grafting with tongue-jointing methods, it is not necessary to tie them up and allow them to grow naturally.
Third, the amount of thinning
Grafting sticks grow rapidly. After being tied, they can't solve the problem basically. At this time, they must sparse the “green branches†and reduce the load intensity of grafted bases. Branches were dense branches, back branches, competing branches (branches sprouted under the second bud), branching branches, and stacked branches. The amount of branching accounted for 25-35% of the total number of grafted branches. too much.
Fourth, timely pick up
For grafting of non-viable trees, buds will be budded (with woody buds) in time from July to August.
V. Weak Small Trees "Heavy" Management
For weak trees that are stunted after grafting, special management is required. If the vigor is weak, gibberellin can be used for foliar application. Root joints use multiple microelement fertilizers, rare earth fertilizers or humic acid, amino acid fertilizers to water irrigation. In this way, the tree is strong in resistance and grows faster.
