Embodiment 1

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

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

[0024] B, preparation for grafting: the grafting time is May 12, 2008, on a cloudy day, the semi-lignified branches of Magnolia magnolia were cut to the scion of 10cm long, 2 blades were reserved, and all the other blades were removed;

[0025] C. Grafting: After soaking the scion in 10% sucrose aqueous solution for 8 hours, cut the lower end of the scion into a 3 cm long double-sided bang shape, align the two sides, and make the cut surface smooth; cut off the rootstock from the interface, and then cut it from the center of the section. When splitting is used, the depth is 4 cm; the scion is quickly inserted into the rootstock, so that the cambiu...

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

[0035] A. Selection of scion and rootstock: the scion is selected from semi-lignified branches of purple magnolia, with a thickness of 8mm; the rootstock is selected from magnolia seedlings, and the thickness of the trunk is 12mm;

[0036] B, grafting preparation: the grafting time is selected on May 20, 2009, on a cloudy day, the semi-lignified branches of Magnolia magnolia are cut to the scion of 13cm long, 3 leaves are reserved, and the remaining leaves are removed;

[0037] C. Grafting: After soaking the scion in 15% sucrose aqueous solution for 10 hours, cut the lower end of the scion into a 3 cm long double-sided bang shape, align the two sides, and make the cut surface smooth; cut off the rootstock from the interface, and then cut it from the center of the section. When splitting is used, the depth is 4 cm; the scion is quickly inserted into the rootstock, so that the ...

Embodiment 3

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

[0047] A. Selection of scion and rootstock: the scion is selected from semi-lignified branches of purple magnolia with a thickness of 10mm; the rootstock is selected from magnolia seedlings with a trunk thickness of 15mm;

[0048] B, grafting preparation: the grafting time is selected on June 5, 2010, on a cloudy day, cut the semi-lignified branches of Magnolia magnolia 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 a 4 cm long double-sided bang shape, align the two sides, and smooth the beveled surface; cut off the rootstock from the interface, and use it from the center of the section. To split, the depth is 5 cm; quickly insert the scion into the rootstock, make the cambium on one side of the lower end of the scion closely al...

Abstract

The invention provides a method for grafting Magnolia liliiflora Desr. to Magnolia denudata. The method includes: selecting the scion and the rootstock; performing grafting preparation; grafting; performing management after grafting. The method has the advantages that the Magnolia denudata has fleshy roots and is developed in root system, so that the survival rate of the grafted seedling is guaranteed; both the Magnolia denudata and the Magnolia liliiflora Desr. belong to Magnoliaceae, so that the scion and the rootstock are high in affinity, grafting success rate is increased greatly, and thegrowth speed of the grafted seedling is increased; the Magnolia denudata is high in cold resistance and can safely live through the winter at minus 20 DEG C, so that the grafted Magnolia liliiflora Desr. can be planted in northern cold regions and has outdoor overwintering ability; the method is simple, convenient, high in survival rate, capable of greatly enhancing the cold resistance of the Magnolia liliiflora Desr., and capable of achieving Magnolia liliiflora Desr. planting in north and northeast of China and allowing the Magnolia liliiflora Desr. to successfully live through the winter.
