Longan tree grafting method

Abstract

The invention provides a longan tree grafting method. The method includes the steps of scion and stock selection, grafting preparation, grafting and management after grafting. According to the method, because the roots of seedling longan trees are arbor woody roots and a root system is flourishing, the grafting survival rate is guaranteed by adopting the seedling longan trees as stocks; because the seedling longan trees and high-quality longan trees belong to the same family and the affinity of scions and the stocks is strong, the grafting success rate is greatly improved, and the growth rate of grafted seedlings after grafting is also improved; because the longan trees have strong drought resisting and low temperature resisting ability, the grafting survival rate can be guaranteed under the conditions of draught and low temperature, and grafted longan trees can blossom and bear fruit within a year and have the ability of surviving the winter in the open field and blossoming and bearing fruit in the current year. The method for achieving top grafting of the high-quality longan trees through the poor-quality seedling longan trees has the advantages that operation is easy and convenient to carry out, the survival rate is high, the coverage rate of high-quality varieties of longan trees is improved, and the purpose of changing poor-quality seedling varieties into the high-quality varieties is achieved.

Description

technical field [0001] The invention relates to the field of plant grafting, in particular to a method for grafting high-quality longan from low-quality longan seedlings. Background technique [0002] In my country, longan 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. Plants in the genus Longan are less resistant to cold, so they are mostly distributed in tropical and subtropical regions of Asia, and are mainly produced in southern provinces such as the east, south and southeast of Guangxi, Guangdong, Fujian and the hillsides of Taiwan. Longan trees like warm and humid climates, and are not resistant to severe cold. The lowest temperature for longan tree overwintering is not lower than 0°C. Once the temperature is lower than 0°C, the normal physiological activities of the plant will be affected, the absorption capacity of the roots wi...

[0003] Inferior longan seed trees are fruit trees grown directly from ordinary longan seeds. Generally, the trees are more than 8 years old before they begin to bloom and bear fruit. However, the fruit produced is small, with thin flesh and large core. Well-developed root system and strong vegetative growth
