Problems solved by technology

[0004] Michela is not resistant to severe cold, so its planting range is limited to the southern provinces, and it cannot survive the winter in the open fields in cold climate areas such as the north, so it is difficult to promote it on a large scale.

Embodiment 1

[0022] The method for grafting magnolia with Michelia chinensis comprises the following steps:

[0023] A. Selection of scion and rootstock: the scion is made of semi-lignified branches of Michelia japonica, with a thickness of 5mm; the rootstock is magnolia seedlings, and the thickness of the trunk is 10mm;

[0024] B, preparation for grafting: the grafting time was May 12, 2008, on a cloudy day, cut the semi-lignified branches of Michelia chinensis to the scion with a length of 10 cm, keep 2 leaves, and remove the remaining leaves;

[0025] C. Grafting: Put the scion into 10% sucrose aqueous solution and soak for 8 hours, cut the lower end of the scion into 3 cm long double-sided, the cross-section is bang-shaped, the two sides are aligned, and the cut surface is smooth; the rootstock is cut off from the interface, and then Split with a knife at the center of the section with a depth of 4 cm; quickly insert the scion into the rootstock so that the cambium on one side of the ...

[0034] The method for grafting magnolia with Michelia chinensis comprises the following steps:

[0035] A. Scion and rootstock selection: the scion is made of semi-lignified branches of Michelia chinensis, with a thickness of 8mm; the rootstock is magnolia seedlings, with a trunk thickness of 12mm;

[0036] B. Grafting preparation: the grafting time was selected on May 20, 2009, on a cloudy day, cut the semi-lignified branches of Michelia chinensis to the scion with a length of 13 cm, keep 3 leaves, and remove the remaining leaves;

[0037] C. Grafting: Put the scion into 15% sucrose aqueous solution and soak for 10 hours, cut the lower end of the scion into 3 cm long double-sided, the cross-section is bang-shaped, the two sides are aligned, and the cut surface is smooth; the rootstock is cut off from the interface, and then from the Split with a knife at the center of the section with a depth of 4 cm; quickly insert the scion into the rootstock so that the cambium on one side...

Embodiment 3

[0046] The method for grafting magnolia with Michelia chinensis comprises the following steps:

[0047] A. Selection of scion and rootstock: the scion uses semi-lignified branches of Michelia chinensis, with a thickness of 10mm; the rootstock chooses magnolia seedlings, and the thickness of the trunk is 15mm;

[0048] B. Grafting preparation: the grafting time was June 5, 2010, on a cloudy day, cut the semi-lignified branches of Michelia chinensis to the 15cm long scion, keep 4 leaves, and remove the remaining leaves;

[0049] C. Grafting: After soaking the scion in saturated saline solution for 12 hours, cut the lower end of the scion into 4 cm long double-sided, the cross-section is bang-shaped, the two sides are aligned, and the cut surface is smooth; the rootstock is cut off from the interface, and then from the cross-section Cleave the center with a knife to a depth of 5 cm; quickly insert the scion into the rootstock so that the cambium on one side of the lower end of th...

Abstract

The invention provides a method for grafting Michelia figo on magnolia denudate. The method includes the steps of scion and rootstock selection, grafting preparation, grafting and management after the grafting. Due to the facts that the magnolia denudata is provided with fleshy roots and root systems are strong, the survival rate of grafting seedlings is guaranteed. The Michelia figo and the magnolia denudata both belong to magnoliaceae, the scion and rootstock affinity is strong, the grafting success rate is improved greatly and the growth of the grafting seedlings after the grafting is also accelerated. The magnolia denudata has stronger cold-resistant capability and can safely live through the winter under the condition of minus 20 DEG C, so the grafted Michelia figo can be planted at cold northern regions and can have the capability of living through the winter in the open field. The method for grafting the Michelia figo on the magnolia denudate is simple, convenient and high in survival rate, greatly enhances the cold-resistant capability of the Michelia figo, achieves planting of the Michelia figo at the northern and northeast regions of China, and enables the Michelia figo to successfully live through the winter in the open field.

Description

technical field [0001] The invention relates to the field of plant grafting, and specifically designs a method for grafting Michelia magnolia. Background technique [0002] In our country, michelia michelia has been a familiar and favorite fragrant flower plant since ancient times. Its smell is strong and mellow but not greasy, and it is also an excellent natural spice. It can be used to refine fragrant sesame oil, and its flowers can also be picked for supply. As a spice used in tea making. There are nearly 50 species of plants in the genus Michelia, which are less cold-resistant, so most of them are distributed in tropical, subtropical and temperate geographical regions of Asia. There are more than 30 species of native plants in China, mainly produced in southern provinces Such as the mountain slopes in southern Jiangxi, Guangdong, Fujian, and Taiwan. Michelle likes a warm and humid climate, not suitable for exposure to the sun, and is not resistant to severe cold. The ...
