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; however, grafting during the dormant period has a short grafting time and is difficult to master. The rootstock must be cultivated one year in advance, and it takes two years to be out of the nursery and other unfavorable factors. , has certain limitations. Square budding has requirements for the specifications and quality of scion and rootstock, especially the thickness of scion generally cannot be less than 0.8cm, and the bud piece must be thick and the degree of lignification must be good.

Embodiment 1

[0022] Specific steps are as follows:

[0023] 1. Grafting time selection: choose the first ten days of July during the growth period of Fulu Zifeng;

[0024] 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 0.5cm, and the lower part can be used as a rootstock when it has been semi-lignified;

[0025] 3. Selection of scions: select the semi-lignified branches of the year-old Fulu Zifeng without pests and diseases, grow vigorously, develop full axillary buds, and have a thickness of more than 0.3cm as scions, which are cut and used now;

[0026] 4. Grafting: Graft the rootstock at a smooth bark position 5-10cm from the ground, leave no leaves below...

Embodiment 2

[0030] Specific steps are as follows:

[0031] 1. Selection of grafting time: choose mid-June during the growth period of Fulu Zifeng;

[0032] 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 0.5cm, and the degree of lignification is good. At this time, it can be used for rootstocks for grafting;

[0033] 3. Selection of scions: Take the semi-lignified branches of Phlox maple that are free from diseases and insect pests, grow vigorously, have well-developed axillary buds, and have a thickness of more than 0.3cm as scions, which are cut and used now;

[0034] 4. Grafting: Graft the rootstock at a smooth bark position 5-10cm from the ground, leave no leaves below the grafting position, leave 2-3 leaves above the g...

[0038] Specific steps are as follows:

[0039] 1. Selection of grafting time: choose mid-July during the growth period of Fulu Zifeng;

[0040] 2. Rootstock cultivation: before the germination of sweetgum sweetgum, select a tree with a straight trunk, no pests and diseases, and a diameter of 10-15cm in situ, and cut it in situ to cultivate rootstock branches for grafting, leaving a stem height of 2.2m. -Cultivate 6 robust and well-distributed branches, and remove all other budding 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 for grafting with rootstock;

[0041] 3. Selection of scions: Take the semi-lignified branches of Phlox maple that are free from diseases and insect pests, grow vigorously, have well-developed axillary buds, and have a thickness of more than 0.3cm as scions, which are cut and used now;

[0042] 4. Grafting: Grafting is car...

Abstract

The invention discloses a method for branch grafting of fortune purple liquidambar formosana in the growing period. The method comprises the steps of grafting time selection, stock cultivation, scion selection, grafting and post-grafting management. The method has the advantages of patch budding, but does not have the high requirement for scion quality of patch budding, scion thickness can be flexibly selected, scions with high lignifications degree, full auxiliary buds and thickness larger than 0.3 cm can be used, scion utilization rate is increased remarkably, and the method has extremely high application and popularization value in production.

Description

technical field [0001] The invention relates to a growth-stage inlay grafting method of phlox maple, in particular to an asexual 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 of Fulu Zifeng;...
