Litchi inferior variety high grafting method

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...
