Problems solved by technology

[0005] Litchi seedlings are grown directly from ordinary litchi seeds. Generally, the seedlings are more than 8 years old before they begin to bloom and bear fruit. Management, but the root system is developed, the vegetative growth is vigorous, and the phenomenon of large and small years is serious

Embodiment 1

[0022] The present invention will be described in detail below in conjunction with the examples.

[0023] Example 1

[0024] A grafting method for tongue grafting of litchi seedlings, comprising the following steps:

[0025] A. Selection of scion and rootstock: The scion is made of high-quality lychee branches with a thickness of 5-8mm; the rootstock is lychee seedlings that are more than one year old. ;

[0026] B. Grafting preparation: The grafting time is cloudy days from February to March 2013. Cut the high-quality litchi branches to 60-70mm long scions, and keep 2-3 full bud eyes on the scions; remove the leaves;

[0027] C. Grafting: Cut the scion into 30mm-40mm long, and cut it out at the place where 1-2 full bud eyes are left on the scion to form an oblique section, the oblique section is 20-30mm long and 8-10mm wide; choose a rootstock with a slightly larger diameter than the scion Cut off the rootstock at the position, and then cut an inclined plane from the high ...

Abstract

The invention provides a tongue grafting method of lichee seedlings. The tongue grafting method of lichee seedlings includes the following steps: selection of scion and stock; preparation for grafting; grafting; and management after grafting. The lichee seedlings are arbor wood roots and the root system is flourishing, so that the survival rate of grafting is guaranteed. The lichee seedlings and the lichee scion with high quality for grafting belong to the same family, so that the scion and stock have strong affinity; the success rate for grafting is greatly improved and the growing speed of the grafted seedlings after grafting is accelerated. The lichee seedlings have relatively higher drought resisting capability, so that the survival rate of grafting can be guaranteed in the drought environment and then the lichee seedlings after grafting can blossom and yield fruit within 3 years. The tongue grafting method of lichee seedlings is simple and convenient for grafting, has high survival rate, can improve the coverage rate high quality lichee varieties, and can realize blossoming and fruit yielding of lichee in advance.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of plant grafting, in particular to a grafting method for tongue grafting of litchi seedlings. [0003] 【Background technique】 [0004] 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 dried lychee fruit. Lychee seedlings are dicotyledonous plants, which are less cold-resistant, so they are mostly distributed in tropical and subtropical regions of Asia. They are mainly produced in southern provinces such as the east, south and southeast of Guangxi, Guangdong, Fujian and the hillsides of Taiwan. Litchi seedlings like warm and humid climates, and are not tolerant to severe cold. The minimum temperature for overwintering litchi seedlings 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 c...
