Embodiment 1

[0028] The present invention will be described in detail below in conjunction with embodiments.

[0029] A method for high-position grafting of inferior lychees, including the following steps:

[0030] A. Selection of scion and rootstock: Use high-quality litchi woody branches for scion, 1m; for rootstock, choose inferior seedlings of litchi that are more than 6 years old. Each seedling tree has an average of more than 6 branches, and the thickness of the branches is 20-30mm;

[0031] B. Grafting preparation: The grafting time is February 9, 2010, cloudy day, cut the high-quality litchi branches to a 5cm-long scion, and keep 2-3 full buds on the scion; remove the leaves;

[0032] C. Grafting: Hold the scion in your hand, cut the lower end of the scion into a bevel, the bevel is tongue-like, the cut surface is smooth, and the scion is cut to 5cm long; cut off the rootstock from the interface, and then cut off the skin from the cross section toward the south. See the xylem in the depth,...

Embodiment 2

[0039] A method for high-position grafting of inferior lychees, including the following steps:

[0040] A. Selection of scion and rootstock: Use high-quality litchi woody branches for scion, 8mm; rootstock choose inferior lychee seedling trees that are more than 6 years old, with an average of more than 6 branches per seedling tree, with a thickness of 20-30mm;

[0041] B. Grafting preparation: Grafting time is February 18, 2011, cloudy day, cut the high-quality lychee branches to 4~5cm long scion, keep 2-3 full bud eyes on the scion; remove the leaves;

[0042] C. Grafting: Hold the scion in your hand, cut the lower end of the scion into a bevel, the bevel is tongue-like, and the cut surface is smooth, and cut the scion to a length of 2 to 5 cm; cut off the rootstock from the interface, and then cut off the surface from the cross section toward the south surface Open, see the xylem in the depth, and the width is the same as the cut surface of the scion; quickly put the scion into th...

Abstract

The invention provides a litchi inferior variety high grafting method. The high grafting method includes scion and seedling stock selection; management before stock grafting; grafting; grafting method selection; and management after grafting. Seedling litchi trees have arbor wooden roots, are developed in root system, and can ensure the survival rate of grafting. The seedling litchi trees and high quality litchi trees belong to the same family, the scions and the stocks have high affinity, the success rate of grafting is greatly improved, and the growth speed of grafted seedlings is accelerated after grafting; The litchi trees have high drought resistant and low temperature resistant ability, the survival rate of grafting can be ensured in the conditions of drought and low temperature; the grafted litchi trees can flower and bear fruits within a year, and possess an open field overwintering ability and can flower and bear fruits in current year. The method for high-grafting high quality litchi scions on litchi inferior seedling trees is simple and convenient, is high in survival rate, can improve the coverage of litchi high quality varieties, and can change a litchi inferior variety into a good variety.

Description

[0001] 【Technical Field】 [0002] The invention relates to the field of plant grafting, in particular to a method for high-position grafting of inferior species of litchi. [0003] 【Background technique】 [0004] In our country, the lychee fruit has been a favorite fruit since ancient times. It has a sweet and mellow taste, but it is not greasy. It is also an excellent tonic. The fruit can be baked into cinnamon pulp and dried fruit. The plants of the lychee genus are less hardy, so they are mostly scattered in tropical and subtropical geographic regions of Asia. They are mainly produced in southern provinces such as the eastern, southern and southeastern parts of Guangxi, Guangdong, Fujian and Taiwan. The lychee tree likes a warm, humid climate and cannot tolerate severe cold. The minimum temperature for the overwintering of litchi trees is not less than 0°C. Once the temperature is lower than 0°C, the normal physiological activities of the plant will be affected, the absorption ca...
