Problems solved by technology

[0005] The existing method of persimmon branch grafting is skin grafting. When the thickness of the rootstock is greater than 3cm, the two ears will grow separately after grafting, the healing speed of the grafting joint is slow, the forming is late, and the fruit is prone to premature aging, which affects the later survival rate.

Embodiment Construction

[0013] A persimmon tree grafting method is aimed at rootstocks with a diameter of 3-10 cm for more than 3 years, and the twigs drawn from each scion after the subcutaneous grafting survived are then grafted again, so as to improve the healing speed of the grafting joint and accelerate the growth of the grafted tree. Forming, so as to achieve the purpose of early results.

[0014] A method for grafting persimmon trees, which is characterized in that: in April, hard branches and double spikes are grafted first, and in June and July, the young shoots drawn from the two scions are grafted again.

[0015] As a preference, the grafting operation of the hard branches with double spikes is as follows: select a rootstock that meets the requirements, saw off at the smooth place of the skin, and cut the section with a grafting knife, and cut the skin 1-2cm longitudinally on the opposite sides. Long, deep to the xylem, turn left and right with a knife to make the skin above the incision s...

Abstract

The invention provides a persimmon tree grafting method aiming at a tree stock which grows for more than 3 years and has the diameter of 3-10 cm. After the tree stock is survived through subcutaneous stem grafting, the tree stock is grafted with twigs growing from scions to carry out once nurse graft to improve union speed of a grafting mouth and accelerate shaping of a grafting tree, and therefore the precocity fruiting purpose is achieved. The persimmon tree grafting method is characterized in that a hard twig double scion skin inserting grating method is adopted in April at first, and the once nurse graft is carried out on the twigs growing from two scions from June to July.
