Problems solved by technology

[0003] Fulu Zifeng is a new plant variety, and no one other than the owner of the variety rights has conducted any research on its reproductive technology. Fulu Zifeng is a deciduous tree species, and the grafting of deciduous tree species is traditionally carried out during the dormant period. Branch grafting and grafting during the dormant period have been popularized and applied in the grafting and propagation of Fulu Zifeng, but the grafting time during the dormant period is short, and the timeliness is difficult to grasp. The rootstock must be cultivated one year in advance, and it takes two years to emerge from the nursery and other unfavorable factors. , with certain limitations

Embodiment 1

[0023] Specific steps are as follows:

[0024] 1. Grafting time selection: choose the first ten days of July during the growth period of Fulu Zifeng;

[0025] 2. Cultivation of rootstocks: Establish a small seedbed in the greenhouse in the first ten days of February, concentrate sowing and cultivating the seedlings of sweetgum sweetgum, and transplant them to the outdoor field for cultivation after no frost in the middle and late March, with a planting density of 10×15cm, in early July The diameter of the transplanted seedlings is about 1cm, and the lower part can be used as a rootstock when it has been semi-lignified;

[0026] 3. Scion selection: select the semi-lignified branches of the current year as scions, which are free from diseases and insect pests, grow vigorously, have full axillary buds, and have a thickness of more than 0.8cm as scions, which are cut and used now;

[0027] 4. Grafting: Graft the rootstock at a position 5-10 cm away from the ground where the bark ...

Embodiment 2

[0031] Specific steps are as follows:

[0032] 1. Grafting time selection: choose the first ten days of June during the growth period of Fulu Zifeng;

[0033] 2. Cultivation of rootstocks: At the beginning of March, the 1-2 year-old liquidambar seedlings should be stubbled on the ground. In mid-April, the most vigorous sprouts of each plant were selected as rootstocks for cultivation. The rest of the sprouts were all erased. The germination can reach a ground diameter of about 1cm, and the degree of lignification is good. At this time, it can be used for rootstocks for grafting;

[0034] 3. Selection of scions: take the semi-lignified branches of the current year as scions, which are free from diseases and insect pests, grow vigorously, have well-developed axillary buds, and have a thickness of more than 0.8cm, and cut and use them now;

[0035] 4. Grafting: Graft the rootstock at a position 5-10 cm away from the ground where the bark is smooth, leave no leaves below the graf...

Embodiment 3

[0039] Specific steps are as follows:

[0040] 1. Selection of grafting time: choose mid-July during the growth period of Fulu Zifeng;

[0041] 2. Rootstock cultivation: before the germination of sweetgum sweetgum, select large trees with straight trunks, no pests and diseases, and a diameter of breast height of 10-15 cm in situ to cultivate rootstock branches for grafting. The height of the remaining stems is 2.2m. Cultivate 5-6 branches with strong growth and uniform spatial distribution, and remove all the other sprouted branches. In mid-July, after more than 2 months of intensive cultivation, the branches grow vigorously, and when the thickness and lignification degree are good, they can be used. rootstock for grafting;

[0042]3. Selection of scions: take the semi-lignified branches of the current year as scions, which are free from diseases and insect pests, grow vigorously, have well-developed axillary buds, and have a thickness of more than 0.8cm, and cut and use them...

Abstract

The invention discloses a patch budding method for sweetgum in the growth stage. The method includes the steps of grafting time selection, rootstock cultivation, scion selection, grafting and management after grafting. The patch budding method for sweetgum in the growth stage is applied to big seedling top grafting and small seedling propagation by grafting of sweetgum in the growth stage, can effectively prolong grafting time of sweetgum, shortens the seedling breeding period, and achieves the aim that rootstock is cultivated in the current year, grafting is achieved in the current year, seedlings are formed in the current year. The grafting survival rate is 80% or above, and repair grafting can be carried out for 1-2 times on seedlings which do not survive.

Description

technical field [0001] The present invention relates to a growing period square budding method of the phlox maple, in particular to a vegetative propagation method of a new plant variety. Background technique [0002] Liquidambar formosana H., also known as Liquidambar formosana H., Hamameliaceae, a tall deciduous tree of the genus Liquidambar L. The purple-red leaf color is its main characteristic, which fills the gap in my country's independent cultivation of tall deciduous trees with ever-colored leaves, and has great potential and value in garden applications. [0003] Fulu Zifeng is a new plant variety, and no one other than the owner of the variety rights has conducted any research on its reproductive technology. Fulu Zifeng is a deciduous tree species, and the grafting of deciduous tree species is traditionally carried out during the dormant period. Branch grafting and grafting during the dormant period have been popularized and applied in the grafting and propagation...
