Embodiment 1

[0046] A method for breeding a new variety derived from hybrid maple ingot, comprising the following steps:

[0047] a. Plant the colorful autumn seeds;

[0048] b. After the saplings grow up, find several saplings whose leaves turn red in autumn, and make two groups of saplings whose leaves turn red in autumn, and the two saplings in the group are used as scion and rootstock respectively;

[0049] c. Carry out grafting by cutting grafting at the beginning of April every year, and the specific operation steps are:

[0050] Ⅰ. Cut the scion into branches with a length of 7cm, leave a pair of full buds at the upper end of each branch, and cut it into a wedge shape with a slope length of 1.5cm and another slope length of 1cm at the base of the branch section;

[0051] Ⅱ. Saw off the rootstock at a distance of 4 cm from the ground to form a smooth cut surface, and form an incision vertically downward where the xylem of the cut surface of the rootstock is close to the cambium, and t...

Embodiment 2

[0066] A method for breeding a new variety derived from hybrid maple ingot, comprising the following steps:

[0067] a. Plant the colorful autumn seeds;

[0068] b. After the saplings grow up, a few saplings whose leaves turn red in autumn are found. Every two saplings whose leaves turn red in autumn form a group, and the two saplings in the group are used as scion and rootstock respectively;

[0069] c. Carry out grafting by cutting grafting at the beginning of April every year, and the specific operation steps are:

[0070] Ⅰ. Cut the scion into branches with a length of 10 cm, leave 2 pairs of full buds at the upper end of each branch, and cut it into a wedge with a slope length of 2 cm and another slope length of 1.5 cm at the base of the branch;

[0071] Ⅱ. Saw off the rootstock at a distance of 3 cm from the ground to form a smooth cut surface, and form an incision vertically downward where the xylem of the cut surface of the rootstock is close to the cambium, and the d...

[0078] A method for breeding a new variety derived from hybrid maple ingot, comprising the following steps:

[0079] a. Plant the colorful autumn seeds;

[0080] b. After the saplings grow up, find several saplings whose leaves turn red in autumn, and make two groups of saplings whose leaves turn red in autumn, and the two saplings in the group are used as scion and rootstock respectively;

[0081] c. Carry out grafting by cutting grafting at the beginning of April every year, and the specific operation steps are:

[0082] Ⅰ. Cut the scion into branches with a length of 8 cm, leave a pair of full buds at the upper end of each branch, and cut it into a wedge with a slope length of 1.8 cm and another slope length of 1.3 cm at the base of the branch;

[0083] Ⅱ. Saw off the rootstock at a distance of 4 cm from the ground to form a smooth cut surface, and form an incision vertically downward where the xylem of the cut surface of the rootstock is close to the cambium, and the dept...

Abstract

The invention discloses a breeding method of a new variety derived from hybrid acer truncatum, which includes the following steps: Binfen Qiuse seeds are planted; after saplings grow up, several saplings with red leaves in autumn are found, and saplings with red leaves in autumn form a group, and the two saplings in the group are grafted by a cutting grafting method; in the second year, the best grafted seedlings with red leaves in autumn are selected from the grafted seedlings, and each two grafted seedings are grafted again as a group; in the third year, the best secondary grafted seedlingswith red leaves in autumn are selected from secondary grafted seedlings, and the second grafted seedlings are grafted again; and the best seedlings with red leaves in autumn are selected and observedfor many years. The survival rate of grafting survival rate is about 70% by the method, the new plant variety obtained is named Fuhong, the new variety continues the excellent resistance of acer truncatum and acer platanoides, especially the insect resistance and salt-alkali resistance characteristics are superior to that of the acer truncatum, the most important thing is that the effect of leavesof the new variety turning red is better, the red turning cycle is stable, the leaves can steadily turn red in October every year, and the ornamental value is higher.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a method for breeding a new variety derived from hybrid maple ingots. Background technique [0002] The genus Acer is a family under the order Sapindus. The morphological characteristics are trees or shrubs, with sparse evergreen leaves and small green flowers, which often turn red after autumn and before the leaves fall. [0003] Yuanbao maple belongs to Aceraceae, Acer genus, deciduous tree, 8~10m high. Yuanbao maple has a beautiful tree posture, beautiful leaf shape, red young leaves, and yellow or red leaves in autumn. It is a famous red-leaved tree species in autumn. Weak positive, semi-shade tolerant, cold-resistant, relatively wind-resistant. [0004] Norway Acer, aliases: Purple Leaf Norway Acer, Red Emperor Norway Acer, Big Leaf Red Maple, Acer family Acer, deciduous tree, tree height 9-12 meters. Norway maple is a tree species that grows upright and has a b...
