Embodiment 1

[0036] Embodiment 1 A kind of inverted anvil grafting method of litchi tree

[0037] On March 17, 2021, in the litchi orchard in Shuhui Village, Baihe Town, Pingbian Miao Autonomous County, Yunnan Province, the 3-year-old 'Concubine Xiao' litchi seedling was used as the rootstock, and the 'Technology No. 1' litchi was selected as the scion for grafting experiments. The grafting method is as follows:

[0038] (1) Scion preparation: select the annual or biennial branches with strong growth in the middle and upper part of the canopy periphery of the adult litchi tree of 'Technology No. To protect the axillary buds, cut the lower part of the axillary buds into a short cut surface at an angle of about 45°, and then cut the opposite side (ie the opposite side) of the short cut surface into a 2-4cm long cut surface, cut to the cambium or slightly xylem, and then cut from 1cm above the axillary buds Cut the branches into scions (such as figure 1 shown).

[0039] (2) rootstock proce...

[0043] Embodiment 2 A kind of inverted anvil grafting method of litchi tree

[0044] On April 11, 2021, in Xinzhai Litchi Orchard of Longgu Village Committee, Yuping Town, Pingbian Miao Autonomous County, Yunnan Province, the 6-year-old 'Brown Mao Li' litchi seedling was used as the rootstock, and the 'Concubine Xiao' litchi was selected as the scion for grafting experiments , the specific grafting method is as follows:

[0045] (1) Scion preparation: Select the annual or biennial branches with strong growth in the middle and upper part of the canopy of the adult litchi tree of 'Concubine Xiao', full of axillary buds, and no pests and diseases as scions, and remove the leaves and top shoots of the branches, leaving only short petioles To protect the axillary buds, cut the lower part of the axillary buds into a short cut surface at an angle of about 45°, and then cut the opposite side (ie the opposite side) of the short cut surface into a 2-4cm long cut surface, cut to the camb...

Embodiment 3

[0050] Embodiment 3 A kind of inverted stock grafting method of litchi tree

[0051] On July 15, 2020, at the experimental base in Xiaojiezi Village, Yuping Town, Pingbian Miao Autonomous County, Yunnan Province, the 3-year-old 'Huaizhi' lychee seedlings were used as the rootstock and the 'Fengshan Red Lantern' lychee was used as the scion for grafting experiments. The specific grafting method is as follows:

[0052] (1) Scion preparation: Select the annual or biennial branches with strong growth, full axillary buds, and no pests and diseases in the middle and upper parts of the adult litchi tree crown periphery of 'Fengshan Red Lantern' as the scion, and remove the leaves and top shoots of the branches, leaving only short The petiole protects the axillary buds. The lower part of the axillary buds of the branch is cut into a short cut surface at an angle of about 45°, and the opposite side (ie the opposite side) of the short cut surface is cut into a 2-4cm long cut surface, cu...

Abstract

The invention belongs to the technical field of plant grafting and seedling raising, and particularly relates to a grafting method for improving the grafting survival rate of litchi trees in a rainy season and application of the grafting method. Compared with a traditional grafting method, the inverted stock grafting method for the litchi trees has the advantages that, inverted stocks have the effect of drawing branches, and the stocks can provide moisture and mineral nutrient elements for scions; meanwhile, the inverted stock parts can provide carbon nutrition such as photosynthetic assimilation substances for the stocks through phloem parts, so that the vitality of the stocks is maintained, and the situation that the stocks are shrunk and cracked, and the grafting survival rate is affected is prevented; and in addition, longitudinal sections left at the grafting openings of the stocks when the inverted stocks are sheared are beneficial for removing redundant water vapor and preventing the grafting openings from being rotten due to accumulated water, so that the grafting survival rate of litchi trees in the rainy season is improved. Therefore, the inverted stock grafting method can solve the problem that scions are necrotic due to ponding of grafting unions in the litchi grafting process, and the survival rate of grafting of litchis in rainy seasons is increased.

Description

technical field [0001] The invention belongs to the technical field of plant grafting and seedling cultivation, and in particular relates to a grafting method and an application thereof for improving the survival rate of litchi tree grafting in rainy seasons. Background technique [0002] Litchi (scientific name: Litchi chinensis Sonn.) is native to southern China. It is a subtropical fruit tree, an evergreen tree, about 10 meters high. When the fruit is ripe, the peel has scaly protrusions, bright red, purple red, and the flesh is translucent and creamy. , but not resistant to storage. [0003] Litchi is a subtropical fruit tree, warm in nature, evergreen tree, usually no more than 10 meters high, sometimes up to 15 meters or higher, gray-black bark; branchlets cylindrical, brownish red, densely white lenticels. Leaves with petioles 10-25 cm long or over; leaflets 2 or 3 pairs, less 4 pairs, thin leathery or leathery, lanceolate or ovate-lanceolate, sometimes oblong-lanceo...
