Embodiment 1

[0025] A method for grafting and propagating Chinese crabapple, comprising the steps of:

[0026] (1) Preparation before grafting

[0027] In 3 days before the grafting, the rootstock seedlings were continuously watered, and the middle part of the middle and upper branches of the healthy and vigorous growth of the plants was collected as the scion, and then the blades on the scion were cut off from the leaf base, and the petioles were retained. The moisture content of the rootstock seedlings was 10%;

[0028] (2) Cut rootstock

[0029] At a place where the rootstock is 10-20 cm above the ground, select the straight and smooth part of the stem and cut the first cut obliquely downward at an angle of 20°. The depth is 1 / 3 of the dry diameter and the length is 2 cm, and then the bottom of this cut is 1 cm upward. Cut the second knife downward at a 45° angle until it reaches the first incision, remove and cut the scutellum, and complete the rootstock incision, in which a catheter...

Embodiment 2

[0039] A method for grafting and propagating Chinese crabapple, comprising the steps of:

[0040] (1) Preparation before grafting

[0041] In 4 days before grafting, the rootstock seedlings were continuously watered, and the middle part of the middle and upper branches of the healthy and vigorous growth of the plants was collected as the scion, and then the blades on the scion were cut off from the leaf base, and the petioles were retained. The moisture content of the rootstock seedlings was 15%;

[0042] (2) Cut rootstock

[0043] At the place where the rootstock is 15 cm above the ground, select the straight and smooth part of the stem and cut the first cut obliquely downward at an angle of 25°. The depth is 11 / 30 of the dry diameter and the length is 3 cm. Cut the second knife downward at an angle of ° until it is at the first incision, remove and cut the scutellum, and complete the rootstock incision, in which a catheter is inserted;

Embodiment 3

[0053] A method for grafting and propagating Chinese crabapple, comprising the steps of:

[0054] (1) Preparation before grafting

[0055] In 5 days before grafting, the rootstock seedlings were continuously watered, and the middle part of the middle and upper branches of the healthy and vigorous growth of the plants was collected as the scion, and then the blades on the scion were cut off from the leaf base, and the petioles were retained. The moisture content of the rootstock seedlings was 20%;

[0056] (2) Cut rootstock

[0057] At the place where the rootstock is 20 cm above the ground, select the straight and smooth part of the stem and cut the first cut obliquely downward at a 30° angle. The depth is 2 / 5 of the dry diameter and the length is 4 cm. Cut the second knife downward at an angle of ° until it is at the first incision, remove and cut the scutellum, and complete the rootstock incision, in which a catheter is inserted;

Abstract

The invention discloses a grafting breeding method for Chinese flowering crabapple. The water content of middle stock seedling land ranges from 10% to 20%, callus tissue can be formed, the grafting joint butt-seam difficulty and the binding difficulty are reduced, and the final survival rate is increased; a conduit is inserted into a stock, and can continuously conduct conveying and exchanging between the stock and scions, the normal nutritional requirement of the scions is guaranteed, a bandage is a film of 0.03 mm-0.04 mm, the film is disinfected before being used, and it can be prevented that germs invade to infect a wound; a binding part is subjected to nutrient solution filling, and attaching of the wound can be promoted. The Chinese flowering crabapple bred with the grafting breeding method has the advantages of being high in final survival rate and small in incision infection, the market potential is huge, and prospects are broad.

Description

technical field [0001] The invention belongs to the field of flower propagation, and more specifically, the invention relates to a grafting and propagation method of crabapple. Background technique [0002] Begonias belong to the genus Malus ( Malus ) variety of plants and the genus Papaya ( Chaenomeles ) Generic and common names of several plants. Representative plant crabapple (scientific name: Malus spectabilis ) and papaya (scientific name: Chaenomeles sinensis ) are shrubs or small trees of the Rosaceae family. They are famous ornamental tree species in China and are commonly cultivated in various places. Horticultural varieties are pink doublet and white doublet. Begonias are mostly ornamental flowers and trees used for urban greening and beautification (although there are many varieties with high edible value of fruits). Many of them are famous ornamental plants, such as: Xifu Begonia, Suisi Begonia, Sticking Begonia and Papaya Begonia, commonly known as "Fou...
