Problems solved by technology

However, this method adopts high-level grafting, requiring Magnolia to reach more than 3 meters before it can be used as a rootstock for grafting, and it needs to process the meristematic rootstock branches for many times, which has higher requirements for the rootstock, which is not conducive to large-scale reproduction.

Embodiment 1

[0025] The grafting and breeding technique of Magnolia safflower comprises the steps:

[0026] Rootstock treatment: Select a 1-year-old Miyama Michelia Michelia in the nursery with a diameter of 1-2cm, strong growth, and no pests and diseases as the rootstock. Saw the rootstock 40cm above the ground, then disinfect it, and graft it the next day. The grafting time Choose late February;

[0027] Scion treatment: select the middle and upper periphery of the adult mother tree of Magnolia safflower, grow vigorously, have no pests and diseases, and have full axillary buds as the scion. Remove the leaves and keep the axillary buds. A small slope of 1 cm, the length of the scion is 10 cm, and then treated with a high-voltage electrostatic field with an intensity of 30KV / cm, the treatment time is 120s, and then immersed in the conditioner for 60 minutes;

[0028] The regulator is prepared according to the following steps: take 3 g of indolebutyric acid, 2 g of diethyl ethyl hexanoate,...

Embodiment 2

[0032] The grafting and breeding technique of Magnolia safflower comprises the steps:

[0033] Rootstock treatment: Select a 1-year-old Miyama Michelia Michelia in the nursery with a diameter of 1-2cm, strong growth, and no pests and diseases as the rootstock. Saw the rootstock 40cm above the ground, then disinfect it, and graft it the next day. The grafting time Choose late February;

[0034] Scion treatment: select the middle and upper periphery of the adult mother tree of Magnolia safflower, grow vigorously, have no pests and diseases, and have full axillary buds as the scion. Remove the leaves and keep the axillary buds. A small slope of 1 cm, with a scion length of 8 cm, is then treated with a high-voltage electrostatic field at a strength of 40KV / cm, and the treatment time is 120s, and then immersed in the conditioner for 60 minutes;

[0035] The regulator is prepared according to the following steps: take 3 g of indolebutyric acid, 2 g of diethyl ethyl hexanoate, and 1...

Embodiment 3

[0039] In late August of the same year, investigation and statistics were carried out on the graft survival rate results of each treatment in this experiment (taking the process of Example 1 as an example), see Table 1 for details.

[0040] Table 1 Comparison of survival rate of different rootstocks

[0041] rootstock

[0042] Conclusion: In the present invention, the magnolia safflower, Lechang Michelia, Guangyulan, white Magnolia and Shenshan Michelia were used as rootstocks, and the grafting techniques of each group were exactly the same. It can be seen from Table 1 that the grafting survival rate of Michelia Michelia as rootstock is the highest, and only the annual Michelia Michelia as rootstock can be used to complete the grafting process, which improves the breeding rate of Magnolia safflower.

Abstract

The invention belongs to the technical field of plant breeding and discloses a grafting breeding process of Magnolia wufengensis, comprising the steps of 1) treating a rootstock; 2) treating a scion;3) grafting; 4) carrying out management in late stage of grafting. The grafting breeding process of Magnolia wufengensis provides high survival rate and high woods breeding speed.

Description

technical field [0001] The invention belongs to the technical field of plant breeding, and in particular relates to the grafting and breeding technology of safflower magnolia. Background technique [0002] Magnolia (Magnolia denudata Desr.), is a deciduous tree of Magnoliaceae, Magnoliaceae, Magnolia, also known as Magnolia, Wangchun, Magnolia. It is native to the provinces in central and southern China, and is now cultivated in Beijing and the south of the Yellow River Basin. Magnoliaceae Magnolia subgenus, deciduous trees. The flowers are white to lavender, large and fragrant, with a cup-shaped corolla. The flowers open first, and the leaves grow later. The flowering period is about 10 days. Mulan is a famous flower tree in China, and it is an important ornamental tree in early spring in the south. The shape of magnolia flower is very similar to lotus flower. When it is in full bloom, the petals spread to the four directions, making the courtyard blue and white, and the...
