Problems solved by technology

Most horticultural varieties are propagated by grafting. The survival rate of existing grafting methods is not high. In order to improve the survival rate of grafting, the first scion is usually dipped in wound healing agent before grafting. However, wound healing agent will reduce the survival rate of plants. growth rate, so the growth and development of the first scion after grafting are adversely affected, and the improvement of the grafting survival rate is limited. Therefore, a method for improving the grafting success rate of Begonia flowers is badly needed

Embodiment 1

[0032] A double grafting method of Chinese crabapple, comprising the steps:

[0033] 1. a double grafting method of Chinese crabapple, is characterized in that, comprises the steps:

[0034] (1) After November every year and before the winter solstice, select crabapple seedlings as grafting rootstocks, keep the branches with a diameter of more than 5cm on the rootstock, remove the branches with a diameter of less than 5cm, and wrap the rootstock with thermal insulation materials after subtracting the branches Wrap the formed wound for more than 10 days, and then replace the insulation material again until March to May of the next year; the insulation material includes the first gauze layer, cotton layer and second gauze layer arranged sequentially from inside to outside.

[0035] (2) Around the described rootstock, the depth of digging is a pit of 2 meters, and the crabapple branches and leaves cut out in the step (1) and earthworms and animal excrement are bought into the pit...

Embodiment 2

[0044] (1) After November every year and before the winter solstice, select crabapple seedlings as grafting rootstocks, keep the branches with a diameter of more than 5cm on the rootstock, remove the branches with a diameter of less than 5cm, and wrap the rootstock with thermal insulation materials after subtracting the branches Wrap the formed wound for more than 20 days, and then replace the insulation material again until March to May of the next year; the insulation material includes the first gauze layer, the cotton layer and the second gauze layer arranged in sequence from the inside to the outside.

[0045] (2) Around the described rootstock, the depth of digging is a pit of 3 meters, and the crabapple branches and leaves cut out in the step (1) and earthworms and animal excrement are bought into the pit; the weight of the earthworms is the 2% of the branches and leaves, the weight of the animal manure is 5 times that of the branches and leaves of the crabapple.

Abstract

The invention provides a double grafting method for Malus spectabilis. The double grafting method comprises the steps: (1) selecting a Malus spectabilis seedling as a grafting rootstock; (2) pitting around the rootstock, and burying the sheared Malus spectabilis branches and leaves as well as feces of earthworms and animals into the pit; (3) selecting a first scion; (4) firstly, soaking the firstscion into a first scion treatment solution, then, inserting the first scion into a rock wool block, and carrying out freezing; (5) cutting out a first scion socket in the rootstock; (6) obliquely inserting the first scion into the first scion socket; (7) carrying out wax sealing; (8) carrying out management; and (9) in August of the year, preparing a second scion according to the step (3), preparing a second scion socket according to the step (5), then, inserting the second scion into the second scion socket sequentially according to the steps (6), (7) and (8), and grafting the second scion on the rootstock. By using the method provided by the invention, the breeding success rate of the Malus spectabilis can be effectively increased.

Description

technical field [0001] The invention relates to a method for grafting fruit trees, in particular to a double grafting method for crabapple. Background technique [0002] Begonia flower (scientific name: Malus spectabilis (Ait.) Borkh): tree, up to 8 meters high; branchlets are thick, cylindrical, pubescent when young, and gradually fall off, reddish-brown or purple-brown when old, glabrous. The flowering period is from April to May, and the fruiting period is from August to September. It is known as "National Beauty". It is a unique plant in China. The seedlings of crabapple grow slowly, and it will take 5-6 years to bloom, and often produce variety variation, so it is only used as rootstock cultivation and hybrid breeding. Most horticultural varieties are propagated by grafting. The survival rate of existing grafting methods is not high. In order to improve the survival rate of grafting, the first scion is usually dipped in wound healing agent before grafting. However, w...
