Embodiment 1

[0025] The method of lychee tree grafting includes the following steps:

[0026] A. Selection of scion and rootstock: Use high-quality litchi woody branches for scion, with a diameter of 0.5~10 mm; rootstock choose lychee saplings of more than 2 years old, and the average height of each seedling sapling is 200~300 mm. , The branch thickness is 10-20mm;

[0027] B. Grafting preparation: The grafting time is January 16, 2012, cloudy day, cut the high-quality litchi branches to a 2cm-long scion, and retain 1-2 full bud eyes on the scion; remove the leaves;

[0028] C. Grafting: Hold the scion in your hand and cut the lower end of the scion into a bevel. The bevel is tongue-shaped, and the cut surface is smooth. Cut the scion to a length of 5cm; 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, and the width is the same as the cut surface of the scion; quickly put the scion into the xylem of the peele...

[0035] The method of lychee tree grafting includes the following steps:

[0036] A. Selection of scion and rootstock: Use high-quality lychee woody branches for scion, with an average diameter of about 10mm; rootstock choose lychee seedlings of more than 2 years old, with an average height of more than 250 mm per seedling, and a thickness of 10-20mm. ;

[0037] B. Grafting preparation: The grafting time is February 25, 2013, cloudy day, cut the high-quality litchi branches to a scion with a length of 1~2cm, and retain 1-2 full bud eyes on the scion; remove the leaves;

[0038] C. Grafting: Hold the scion in your hand, cut the lower end of the scion into a bevel, the bevel is tongue-shaped, and the cut surface is smooth. Cut the scion to a length of 1~2cm; cut off the rootstock from the interface, and then cut it from the cross-section to 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 the xylem...

Abstract

The invention provides a litchi tree grafting method which comprises the following steps of scion and seedling tree stock selecting, sapling seedling stock grafting pre-managing, grafting, applying a grafting method and grafting post-managing. A seedling litchi sapling tree has an arbor root and has a developed root, and the survival rate of grafting is guaranteed. The seedling litchi sapling tree and a superior litchi tree belong to the same family, a scion and a stock are strong in compatibility, the successful rate of grafting is greatly improved, and the growing speed of grafting seedlings after grafting is accelerated; the seedling litchi sapling tree has a strong drought and low temperature resistant ability, the survival rate of grafting can be guaranteed under a dry and low temperature condition, so that the litchi sapling tree after grafting can blossom and yield fruits within three years and has the abilities of passing the winter in an exposing mode and easy survival transplanting. The inferior litchi sapling tree grafting method is simple, convenient and high in survival rate, the coverage of high quality litchi trees is improved, and the popularization of good quality litchi trees are realized.

Description

Technical field [0001] The invention relates to the field of plant grafting, in particular to a method for lychee tree grafting. Background technique [0002] In our country, the lychee fruit has always been a favorite fruit for everyone. Because of its sweet and mellow taste, it is not greasy, and it is also an excellent tonic. The fruit can be baked into cinnamon meat and dried fruit. Litchi trees are not cold-resistant, so they are mostly scattered in tropical and subtropical geographic regions of Asia. They are mainly produced in southern provinces such as eastern, southern and southeastern 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 capacity of the root will be weakened, and the tender branches and le...
