Embodiment 1

[0024] The circled 'Huaizhi' lychee seedlings were planted in 30-liter plastic pots with 1 part of peat soil, 2 parts of mushroom residue, and 3 parts of red loam soil. That is, grafting. The grafting was carried out on April 12, 2014. The branches were cut short to a thickness of 1.0 to 1.5 cm, and the '9918' lychee was grafted on it. and make up in time. After the grafting is completed, the scion at the upper end and the rootstock at the lower end are processed as follows respectively after the grafting:

[0025] The lower part of the graft joint: Periodically wipe off the buds that grow from the lower end of the graft joint until mid-September.

[0026] The upper part of the grafting interface: After the grafting survives, the upper part of the grafting interface (ie the scion) is pulled out of the tender shoots, and the leaves are sprayed with abamectin to control the new shoot pests such as leaf rollers, regularly apply compound fertilizers and trace elements, and culti...

Embodiment 2

[0029] The circled 'Huaizhi' lychees were planted in 30-liter plastic pots with 1 part of peat soil, 2 parts of mushroom residue, and 3 parts of red loam soil. Grafting was carried out on April 20, 2015. First, the branches were cut short to a thickness of 1.0 to 1.5 cm, and 'March Red' was grafted on it. The method was carried out by cutting and grafting. After 1 to 2 weeks of grafting, the survival was checked. rate, and make up for it in a timely manner. After the grafting is completed, the scion at the upper end and the rootstock at the lower end are processed as follows respectively after the grafting:

[0030] The lower part of the grafting interface: regularly erase the buds that grow from the lower end of the grafting interface (that is, the "Huaizhi" branch as the rootstock) until mid-September.

[0031] The upper part of the grafting interface: After the grafting survives, the upper part of the grafting interface (ie the scion) pulls out the tender shoots, sprays ab...

Embodiment 3

[0034] 'Huaizhi' ring branch seedlings were planted in 30-liter plastic pots with 1 part of peat soil, 2 parts of mushroom residue, and 3 parts of red loam soil. grafting. The grafting was carried out on April 20, 2014. The tip of the branch was cut short to a thickness of 1.0-1.5 cm, and the '9918' lychee was grafted on it, using the method of cutting and grafting. After grafting, new buds will grow at the lower end of the graft interface. Except for retaining one of the buds and letting it shoot out the shoots, the rest of the buds will be wiped off until mid-September. For the buds drawn from the scion on the upper part of the grafting mouth, spray Scherospen to control new shoot pests such as leaf rollers, protect the young shoots, cultivate two new shoots, and make the last shoots mature in early September. When the last shoots are mature, control the vegetative growth and regularly remove the tender shoots or buds on the last shoots. After a period of shoot control, in...

Abstract

The invention belongs to the technical field of litchi cultivation and management, and particularly discloses a method for controlling late-maturing litchis to bloom earlier. The method comprises the following steps: by taking an early-maturing litchi variety as a scion and a late-maturing litchi variety as a rootstock, after a late-maturing litchi plant grows for 2-4 years, grafting the scion of the early-maturing litchi variety into a twig of the late-maturing litchi variety in April, continuously cutting off buds or young shoots growing from the lower end of the graft union after grafting, and stopping cutting the buds or the young shoots in the middle of September; managing the scion at the upper part of the graft union, culturing 1-2 new shoots on the survival grafted scion, controlling a final shoot to be mature at early September, and implementing shoot control treatment, wherein buds of the late-maturing litchi variety at the lower part of the graft union are germinated and flowers grow out. By adopting a grafting technique, the late-maturing litchi variety can bloom as early as the early-maturing litchi variety, the blooming time can be brought ahead for 2-3 months, and the method is breakthrough of a litchi flowering time regulation and control technique.

Description

technical field [0001] The invention relates to the technical field of litchi cultivation and management, in particular to a method for controlling early flowering of late-ripening litchi. Background technique [0002] Lychee is an important specialty fruit in my country and has extremely high economic value. There are many varieties of lychees, and the flowering time varies greatly. In the main lychee producing areas of the Pearl River Delta, the flowering time ranges from early to mid-February of 'Sanyuehong' to 'Huaizhi', 'Glutinous Rice Cake' and 'Guweiwei' Waiting for late-ripening lychees from late March to early and mid-April, the fruit ripening time ranges from early May to mid-July. The quality of the early-maturing varieties is generally worse than that of the late-maturing varieties, but due to the early market, the price is not lower than that of the high-quality late-maturing lychees. For a long time, people have been looking for ways to make late-ripening lyc...
