Problems solved by technology

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

Embodiment 1

[0030] A kind of propagation method of Chinese crabapple, comprises the steps:

[0031] 1. a propagation method of Chinese crabapple, is characterized in that, comprises the steps:

[0032](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.

[0033] (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

[0041] (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.

[0042] (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.

Embodiment 3

[0050] A kind of propagation method of Chinese crabapple, comprises the steps:

[0051] (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 15 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.

[0052] (2) Around the described rootstock, the depth of digging is a pit of 2.5 meters, and the crabapple branches and leaves and earthworms and animal excrement cut off in the step (1) are bought into the pit; the weight of the earthworms is the 1.5% of the branches and leaves, the weight of t...

Abstract

The invention provides a Chinese flowering crabapple breeding method. The Chinese flowering crabapple breeding method comprises the steps that 1, Chinese flowering crabapple seedlings are selected asgrafting stocks; 2, pits are dug around the stocks, and sheared Chinese flowering crabapple branches and leaves, earthworms and animal waste are buried in pits; 3, scions are selected; 4, the scions are firstly put in a scion treating solution for soaking and then are inserted into rock wool blocks for freezing; 5, scion cuts are formed in the stocks through cutting; 6, the scions are obliquely inserted into the scion cuts; 7, wax sealing is performed; 8, management is performed. Before the scions are inserted into the scion cuts, an infusion outlet of an infusion tube are arranged in each scion cut, infusion bags are fixed to the stocks and are communicated with inlets of the infusion tubes, the infusion bags contains a grafting treatment solution, and a solution preparation method comprises the steps that 6-benayl aminopurine, zeatin, saccharose and asparaginic acid are firstly taken, chitosan powder is dissolved in water, and autoclaved sterilization is performed. The success rate of Chinese flowering crabapple breeding can be effectively improved by adopting the Chinese flowering crabapple breeding method.

Description

technical field [0001] The invention relates to a grafting method of fruit trees, in particular to a propagation method of 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. Horticultural varieties are mostly propagated by grafting. The survival rate of the existing grafting methods is not high. In order to improve the survival rate of grafting, the scion is generally dipped in wound healing agent before grafting. However, the w...
