Embodiment 1

[0036] Embodiment 1: The application of this method is carried out in the scientific research and teaching base of South China Agricultural University in Guangzhou City, Guangdong Province. Huanglan is selected as the rootstock, and the lignified branches of Michelia shilu were used as the scion. The specific implementation steps are as follows:

[0037] (1) Grafting rootstock selection: select ground diameter 3.0-4.0cm, grow vigorously, the straight yellow orchid container seedling of stem shape. (2) Grafting time: Grafting in sunny and cloudy weather from January 20 to February 20. Water control management was performed on the rootstock 5 days before grafting.

[0038] (3) Scion collection and processing: From the introduced Michelia shilui mother tree, the lignified branches of the year with strong growth in the middle and upper part, full axillary buds, and no pests and diseases were collected. The length is 8-20cm, and the thickness is 0.6-1.0cm.

Embodiment 2

[0046] Embodiment 2: The application of this method was carried out in the scientific research and teaching base of South China Agricultural University in Guangzhou City, Guangdong Province. Michelia Michelia was selected as the rootstock, and the lignified branches of Michelia shilu were used as scions. The specific implementation steps are as follows:

[0047] (1) Grafting rootstock selection: select about 2.0cm in ground diameter, grow vigorously, and the stem shape is straight and straight.

[0048] (2) Grafting time: Grafting in sunny and cloudy weather from January 20 to February 20. Water control management was performed on the rootstock 5 days before grafting. .

[0049] (3) Scion collection and processing: From the introduced Michelia shilui mother tree, the lignified branches of the year with strong growth in the middle and upper part, full axillary buds, and no pests and diseases were collected. The length is 8-20cm, and the thickness is 0.6-1.0cm.

Embodiment 3

[0057] Example 3: This method was applied in the scientific research and teaching base of South China Agricultural University in Guangzhou City, Guangdong Province. Michelia Lechang was selected as the rootstock, and Michelia shilu grew lignified branches in the same year as the scion. The specific implementation steps are as follows:

[0058] (1) Selection of rootstock for grafting: select a Lechang Michelia seedling with a ground diameter of about 2.0 cm, robust growth, and a straight stem shape.

[0059] (2) Grafting time: Grafting in sunny and cloudy weather from January 20 to February 20. Water control management was performed on the rootstock 5 days before grafting. .

[0060] (3) Scion collection and processing: From the introduced Michelia shilui mother tree, the lignified branches of the year with strong growth in the middle and upper part, full axillary buds, and no pests and diseases were collected. The length is 8-20cm, and the thickness is 0.6-1.0cm.

Abstract

The invention relates to a michelia shiluensis grafting propagation method. Through the steps of grafting root stock selection, scion collection, grafting time, method and post-grafting management measure optimization, michelia champaca, michelia maudiae, michelia chapensis and michelia macclurei are used as stocks; well developed branches of adult trees of michelia shiluensis are used as scions; in December to February, a cut-grafting method is used for grafting; after the grafting, the water control management is performed for 15d; after the scion sprouting branches grow to the length about 15cm, the transplanting is performed from a greenhouse to an outdoor position or a small plastic shed is removed; the water and fertilizer management is enhanced; composite fertilizers are applied once generally in 15d; the fertilization quantity is managed according to conventional seedlings. The method solves the technical problems that the existing parent trees of the michelia shiluensis are very rare; the seeds are insufficient; the germination seedling emergency rate is low; the grafting propagation is difficult and the like. The michelia shiluensis grafting propagation method with the advantages of rich stock resources, stable grafting technology, high grafting survival rate and fast seedling forming speed are provided. Michelia shiluensis seedlings in various specifications can be fast propagated; technical support is provided for rescuing, protecting and efficiently utilizing the rare and endangered lily magnolia germplasm resources of michelia shiluensis; important study values and wide application prospects are realized.

Description

technical field [0001] The invention belongs to the technical field of plant seedling propagation, and in particular relates to a method for grafting and propagating Michelia shilu. Background technique [0002] Shilu Michelia (Michelia shiluensis Chun et Y.F.Wu) belongs to the Michelia genus of Magnoliaceae, an evergreen tree with a height of 20m and a DBH of 60cm. The trunk of this tree is straight, the crown is broad and graceful; the terminal buds are narrowly ellipsoidal, covered with dense orange-yellow or gray shiny serice. Branchlets, leaf sides, petioles, and pedicels all glabrous. Leaf leathery, slightly hard, obovate-oblong, 8-14cm long, 4-7cm wide, apex obtusely rounded, shortly pointed, base wedge-shaped or broadly wedge-shaped, dark green above, pink-green below; petiole 1-3cm long, With wide grooves, no stipules. Fragrant flowers, solitary leaf axils, milky white, cup-shaped, 9 perianths, obovate, 3-4.5cm long, 1.5-2.5cm wide; filaments red; aggregate fruit...
