The invention relates to a management and cultivation method of fruit trees, in particular to a cultivation method of big trees of improved variety of
apricot tree in cold areas along the mountain, which has high
grafting survival rate, and particularly relates to a top-
grafting and superior variety-exchangecultivation method of improved variety of the
apricot tree. The cultivation method comprising the steps of collecting and storing,
cutting ears, boiling
wax liquid,
sealing wax,
pruning stock,
grafting and
cutting ears, performing management after grafting and so on. The method solves the problem that the cion is difficult to store, and comprises the steps of
cutting branches of the improved variety of
apricot tree into 6-7cm of ear sections;
sealing wax for the whole ears; sealing and preserving the ears in the cold place at low temperature, wherein the ears can be preserved for more than 6 months; after the trees in the to-be-grafted area expand leaves, namely, the sap flows, performing grafting; strongly shaping the ansu apricot, common apricot or low-yield local big trees; performing grafting by cleft grafting,
cut grafting, notch grafting and so on; after 7-10 days, germinating and branching, wherein the
survival rate can reach more than 85%; even if part ears do not survive, the ears can be preserved for long period due to
wax sealing of the whole ears; therefore, the un-survival ears can be grafted in time, and then 100% of
survival rate of the tree in this year can be ensured.
