Embodiment 1

[0025] The high-position grafting method of inferior litchi trees comprises the following steps:

[0026] A. Selection of scion and rootstock: the scion is selected from high-quality litchi lignified branches, 1m; the rootstock is selected from inferior litchi seed trees that are more than 6 years old.

[0027] B. Grafting preparation: the grafting time is February 9, 2010, on a cloudy day, cut the high-quality lychee branches to the scion with a length of 5 cm, and keep 2-3 full bud eyes on the scion; remove the leaves;

[0028] C. Grafting: Take the scion in your hand, cut the lower end of the scion into a bevel, the bevel becomes tongue-shaped, and the bevel is smooth, and the scion is as long as 5cm; the rootstock is cut off from the interface, and then peeled off from the section towards the south epidermis, See the xylem for the depth, and the width is consistent with the cut surface of the scion; quickly put the scion into the xylem of the peeled rootstock, the two side...

Embodiment 2

[0035] The high-position grafting method of inferior litchi trees comprises the following steps:

[0036] A. Selection of scion and rootstock: the scion is selected from high-quality litchi lignified branches, 8mm; the stock is selected from inferior litchi seed trees that are more than 6 years old, and each seed tree has an average of more than 6 branches, and the thickness of the branches is 20-30mm;

[0037] B. Grafting preparation: The grafting time is February 18, 2011, on a cloudy day, cut the high-quality litchi branches to the scion with a length of 4-5cm, and keep 2-3 full bud eyes on the scion; remove the leaves;

[0038] C. Grafting: Hold the scion in your hand, cut the lower end of the scion into a bevel, the bevel becomes tongue-shaped, and the bevel is smooth, cut the scion to a length of 2 to 5 cm; cut off the rootstock from the interface, and then peel off the surface from the section towards the south. Open, see the xylem in depth, and the width is consistent ...

Abstract

The invention provides an inferior litchi tree top grafting method which comprises the following steps of scion and seedling tree stock selecting, stock grafting pre-managing, grafting, grafting method and grafting post-managing. A seedling litchi tree has an arbor root and has a developed root, and the survival rate of grafting is guaranteed. The seedling litchi tree and a superior litchi tree belong to the same family, a scion and a stock are strong in compatibility, the successful rate of grafting is greatly improved, and the growing speed of grafting seedlings after grafting is accelerated; the litchi tree has a strong drought and low temperature resistant ability, the survival rate of grafting can be guaranteed under a dry and low temperature condition, so that the litchi tree after grafting can blossom and yield fruits within a year and has the abilities of passing the winter in an open field and blossoming and yielding the fruits just in one year. The inferior litchi tree grafting method is simple, convenient and high in survival rate, the coverage of high quality litchi trees is improved, and the inferior litchi tree can be changed into the superior litchi tree.

Description

technical field [0001] The invention relates to the field of plant grafting, in particular to a method for high-position grafting of inferior litchi trees. Background technique [0002] In my country, lychee fruit has been a favorite fruit since ancient times. It tastes sweet and mellow but not greasy, and it is also an excellent tonic. The fruit can be dried into laurel meat and dried fruit. The plants in the genus Litchi are less resistant to cold, so most of them are distributed in the tropical and subtropical regions of Asia, and are mainly produced in the southern provinces such as the east, south and southeast of Guangxi, Guangdong, Fujian and the mountain slopes of Taiwan. Litchi trees like warm and humid climates, and are not tolerant to severe cold. The minimum temperature for overwintering litchi trees is not lower than 0°C. Once the temperature is lower than 0°C, the normal physiological activities of the plants will be affected, the absorption capacity of the ro...
