Embodiment Construction

[0012] 1) Selection of rootstock and ear combination: According to years of practical experience, Heli (Huaizhi) can be used as the rootstock of Jizui Litchi, Guiwei, Nuomi Ci, Baitangying, Feizixiao and Baila. However, the incompatibility rate of glutinous rice cakes connected with dazao anvil is as high as more than 90%, and the incompatibility rate of black leaves with white sugar poppy is more than 80%.

[0013] 2) Selection of tree age for high grafting and replanting and high grafting parts: Generally, trees under 10 years old are more suitable for high grafting and replanting. The height of the interface is 1-1.5 meters, and the diameter of 1-2 years old is 1-2 cm thick, which is easy to operate. , the survival rate is high, which is conducive to the reasonable cultivation of a well-proportioned canopy skeleton, and the canopy recovers quickly and puts into production quickly. Generally, it will be put into production after the second or third year. For trees over 10 y...

Abstract

The invention discloses an optimization and top grafting breed change technology for the litchi breed, and belongs to the field of agricultural planting. The method comprises the following steps: (1) carrying out stion selection; (2) selecting the top grafting breed change tree age and a top grafting position; (3) selecting a scion: selecting the breed which has excellent comprehensive character and strong competitiveness and is suitable for popularizing locally; (4) carrying out cut grafting. When the optimization and top grafting breed change technology for the litchi breed, which is disclosed by the invention, is adopted, the litchi has the advantages of crisp and sweet pulp, sweet-scented osmanthus fragrance, small seed, high yield and excellent quality.

Description

technical field [0001] The invention relates to the technical field of fruit breeding, in particular to a litchi variety improvement and high-quality transplantation technology. Background technique [0002] Litchi is native to southern China and is a subtropical fruit tree, an evergreen tree about 10 meters high. The peel is mostly scale-like protrusions, bright red, purple. When the pulp is fresh, it is translucent and creamy, with a delicious taste. According to "Compendium of Materia Medica": litchi can "quench thirst, benefit people's color, improve the mind, improve intelligence, strengthen Qi (invigorate the brain and build the body), treat scrofula, tumors, etc. [0003] In recent years, the vast number of fruit farmers in southern my country have not mastered the technology of improving varieties and high-quality grafting when planting lychees on a large scale, which often results in late listing of lychees, low yields, average quality, and poor sales.
