Problems solved by technology

[0004] Liriodendron tulipifera 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 Liriodendron grafting Magnolia, comprises the following steps:

[0023] A, scion and rootstock selection: the scion selects the semi-lignified branches of Liriodendron chinensis, and the thickness is 5mm; the rootstock selects magnolia seedlings, and the trunk thickness is 10mm;

[0024] B, grafting preparation: grafting time is on May 12, 2008, cloudy day, the semi-lignified branch of Liriodendron chinensis is cut to the scion of 10cm length, keeps 2 blades, removes all the other blades;

[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 cambium on one side of the lower end of the scion is closely a...

Embodiment 2

[0034] The method for Liriodendron grafting Magnolia, comprises the following steps:

[0035] A, scion and rootstock selection: the scion selects the semi-lignified branches of Liriodendron chinensis, and the thickness is 8mm; the rootstock selects magnolia seedlings, and the trunk thickness is 12mm;

[0036] B, grafting preparation: the grafting time is selected on May 20, 2009, on a cloudy day, the semi-lignified branches of Liriodendron chinensis are cut to the scion of 13cm long, retain 3 blades, and remove the remaining blades;

[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 cambium on one side of the lower end o...

Embodiment 3

[0046] The method for Liriodendron grafting Magnolia, comprises the following steps:

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

[0048] B, grafting preparation: the grafting time is selected on June 5, 2010, on a cloudy day, the semi-lignified branches of Liriodendron chinensis are cut to the scion of 15cm long, 4 blades are reserved, and the remaining blades are removed;

[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 at the lower end of the ...

Abstract

The invention provides a method for grafting a magnolia by a tulip tree, which includes the following steps: scion and stock selection; preparation for grafting; grafting; and management after grafting. The magnolia is a fleshy root with a developed root system, which ensures the survival rate of grafted seedlings; the magnolia and tulip tree belong to magnoliaceae, the scion and stock have strongaffinity, so that the success rate of grafting is greatly improved, and the growth rate of grafted seedlings after grafting is accelerated; and the magnolia has a strong cold tolerance and can safelyoverwinter at -20 DEG C, which enables the grafted tulip tree to be planted in the northern cold region and has the ability to winter in the open field. The method for grafting the magnolia by the tulip tree is simple and convenient, has high survival rate, greatly enhances the cold resistance of the tulip tree, realizes that the tulip tree can be planted in North China and Northeast China, and be successfully overwintered in the open field.

Description

technical field [0001] The invention relates to the field of plant grafting, and specifically designs a method for grafting Liriodendron chinensis magnolia. Background technique [0002] Liriodendron, a rare plant endemic to China. It is a large deciduous tree, up to 40 meters high, more than 1 meter in diameter at breast height, with gray or taupe twigs. The leaf shape is like a mandarin jacket—the top of the leaf is flat, like the hem of a mandarin jacket; the two sides of the leaf are smooth or slightly curved, like the two waists of a mandarin jacket; the two sides of the leaves protrude outward, like the two sleeves of a mandarin jacket . Therefore, Liriodendron is also called mandarin tree. The flowers are solitary on the top of the branch, with 9 tepals, 3 outer rings calyx-shaped, green, and the inner two rings are petal-shaped yellow-green, with yellow stripes at the base, resembling tulips. Therefore, its English name is "Chinese Tulip Tree", which translates i...
