Embodiment 1

[0018] (1) The grafting time is in the morning and evening when the weather is clear in mid-June, avoiding high temperature and rainy days at noon:

[0019] (2) prepare rootstock: in early spring with 4 years old Acer palmatum seedlings without damage by diseases and insect pests, not germinated, cut off branches at 100cm from the ground, so that only a strong new shoot is kept after it re-germinates and grows as grafting stock; :

[0020] (3) Topping: cut off the young leaves or buds on the top of stock and scion branches 30 days before grafting, so as to impel the lignification of the grafted branches;

[0021] (4) Cut the scion: cut the strong branches in the middle and upper part of the crown of the maple palmatum with high ornamental value, and cut them into wedges with a surface length of 2.0 to 2.5 cm at the lower ends of the opposite leaves of the branches, and 1.0 to 2.5 cm above the opposite leaves. Cut horizontally at 15cm, cut off the leaves and keep the petioles....

Embodiment 2

[0026] (1) The grafting time is in the morning and evening when the weather is clear in the first ten days of July, avoiding high temperature and rainy days at noon;

[0027] (2) Prepare rootstock: in early spring, 3 years old Acer palmatum seedlings without damage by diseases and insect pests and not germinated, cut off the branches at 50cm from the ground, so that only a strong new shoot is kept after it re-germinates and grows to be a grafting stock; ;

[0028] (3) Topping: cut off the young leaves or buds on the rootstock and grafted branch tops 20 days before grafting, so as to impel the lignification of the grafted branches;

[0029] (4) Cut the scion: cut the strong branches in the middle and upper part of the canopy of the chicken claw with high ornamental value, and cut them into wedges with a length of 2.0 to 2.5 cm at the opposite ends of the branches, and 1.0 to 1.5 cm above the opposite leaves. Cut off the leaves and keep the petioles. Wrap the cut scion with a ...

Embodiment 3

[0034] (1) The grafting time is in the morning and evening when the weather is fine in mid-August, avoiding high temperature and rainy days at noon:

[0035] (2) Prepare the rootstock: in early spring, cut off the branches of the 2-year-old Acer palmatum seedlings that are free from fairy pests and have not germinated at a distance of 30 cm from the ground, so that they will re-germinate and only keep a strong new shoot and let it grow as a grafting rootstock. ;:

[0036] (3) Topping: cut off the young leaves or buds on the top of stock and scion branches 20 days before grafting, so as to impel the lignification of grafted branches;

[0037] (4) Cut the scion: cut the robust branches in the middle and upper part of the crown of the maple palmatum with high ornamental value, and cut them into wedges with a length of 2.0 to 2.5 cm at the lower ends of the opposite leaves of the branches, and 1.0 to 1.5 cm above the opposite leaves. Cut horizontally at cm, cut off the leaves and...

Abstract

The invention discloses an acer palmatum twig grafting propagation method, which belongs to a plant vegetative propagation method. The method comprises the following steps of: (1) determining grafting time; (2) preparing rootstock; (3) pinching; (4) cutting scion; (5) cutting the rootstock; (6) joining; and (7) managing grafted seedlings. According to the method, the superior ornamental feature of the acer palmatum can be kept; the rootstock and the scion on which twigs of the acer palmatum are grafted are crisp and tender, and operation such as rootstock cutting and scion cutting is quick, easy and convenient; and thus, the efficiency is increased by over 30 percent compared with hardwood grafting.

Description

technical field [0001] The invention relates to a method for asexual propagation of woody plants, in particular to a method for grafting and propagation of Acer palmatum twigs. Background technique [0002] Acer palmatum (Acer palmatum) is a deciduous tree or small tree of the genus Acer in the Aceraceae family (Aceraceae). rural landscape tree species. In order to maintain the excellent characteristics of Acer palmatum horticultural ornamental varieties, it is generally propagated by asexual reproduction methods such as grafting. [0003] In the middle, spring grafting is the main method. Due to the influence of spring drought and cold spring, the survival rate of grafting is only about 70%. Tender grafting is carried out in the summer growing season. Due to the vitality of semi-lignified branches used as rootstocks and scions High, and the survival rate of grafting is relatively high. According to literature search, there is no propagation method of grafting twigs of Ace...
