Problems solved by technology

This method requires less labor and is easy to master, so it has been widely used. However, the traditional budding method has low budding germination rate and poor growth of budding branches, and some even have dead piles and dead branches, which cannot guarantee the quality of medium-sized coffee Successful Breeding of Fertile Species

Embodiment 1

[0026] Embodiment 1: the method for budding coffee of the present invention

[0027] Cut 7-month-old robust straight branches from the No. 24 high-yield clone mesograin coffee mother tree, cut off all first-level branches and leaves, cut into 3cm-long stems, flatten the cut with a sharp knife, and cut off all the first-level branches and leaves. And the cut stem segment is cut longitudinally, divided into two bud sheets, the section is flattened, and the end of the bud sheet is cut into a 45-degree inclined plane. Use the seedlings of No. 24-10 medium-grained coffee as the rootstock, and open a smooth rectangular opening at the straighter part of the rootstock 5 cm from the ground, reaching as deep as the xylem, and slightly larger in length and width than the buds. The shaved bud pieces are then inserted into the rootstock opening so that the rootstock is aligned with the cambium of the bud pieces. After the rootstock and the cambium of the bud piece are completely healed, l...

[0028] Embodiment 2: the method for budding coffee of the present invention

[0029] Cut 7-month-old strong straight branches from the No. 24-1 high-yield clone mesograin coffee mother tree, cut off all first-level branches and leaves, cut into stems with a length of 4 cm, and use a sharp knife to cut the cut. Cut the cut stem section longitudinally from top to bottom, divide it into two bud slices, flatten the section, and cut the end of the bud slice into a 45-degree inclined plane. Use the seedlings of No. 24 medium-grained coffee as the rootstock, and open a smooth rectangular opening at a relatively straight place 10 cm above the ground, reaching as deep as the xylem, and slightly larger in length and width than the buds. The shaved bud pieces are then inserted into the rootstock opening so that the rootstock is aligned with the cambium of the bud pieces. After the rootstock and the cambium of the bud piece are completely healed, lightly cut the binding bands on both sid...

[0030] Embodiment 3: the method for budding coffee of the present invention

[0031] Cut 7-month-old strong and straight branches from the No. 24-10 high-yield clone mesograin coffee mother tree, cut off all first-level branches and leaves, cut into stems with a length of 3 cm, flatten the cut with a sharp knife, and Cut the cut stem section longitudinally from top to bottom, divide it into two bud slices, flatten the section, and cut the end of the bud slice into a 45-degree inclined plane. Use the seedlings of Xing 28 medium-grained coffee as the rootstock, and open a smooth rectangular opening at a relatively straight place 10 cm above the ground, reaching deep to the xylem, and slightly larger in length and width than the buds. The shaved bud pieces are then inserted into the rootstock opening so that the rootstock is aligned with the cambium of the bud pieces. After the rootstock and the cambium of the bud piece are completely healed, lightly cut the binding bands on bot...

Abstract

The invention relates to the technical field of agriculture cultivation and discloses a method for bud grafting of a coffee tree. According to the method, a bud slice is fixed to a stock; after the cambium of the stock and the cambium of the bud slice are totally healed, bindings on the two sides of a bud point on the bud slice are removed to expose the bud point, and meanwhile, 1-2 longest primary branches on the stock as well as the leaves thereof are reserved, and the remaining primary branches are all sheared off; after the bud point germinates, all the bindings are removed, and meanwhile, flowers and fruits on the reserved primary branches are removed during germination; after the bud point grows as high as 10-20cm, the stock is sheared off transversely from a position 2-3cm above the bud grafting position, and meanwhile, the reserved primary branches are sheared off. According to the method, one-off stock-shearing adopted in traditional methods is replaced with two-time stock-shearing, the primary branches and the leaves thereof are reserved selectively between the two times of stock-shearing, and therefore the defects of the traditional methods adopting one-off stock-shearing that the bud grafting germinating rate is low and bud grafting branches can not grow well are overcome.

Description

technical field [0001] The invention relates to the technical field of agricultural cultivation, in particular to a method for budding coffee. Background technique [0002] Coffee (tree) is a perennial evergreen shrub or small tree of the Rubiaceae family. It is a horticultural perennial economic crop. The fruit is one of the three famous beverages with aroma. The main production areas are Hainan Province and Yunnan Province in China. [0003] There are small, medium and large varieties of coffee. The medium-grained species is a cross-pollinated plant, and the offspring of the seeds propagated with great variation. The yield of different plants in the same garden block is quite different. Therefore, the method of asexual reproduction to cultivate excellent seedlings can better retain the quality of excellent varieties. traits. Asexual reproduction mainly adopts two methods of cutting and grafting. At present, coffee grafting mostly adopts budding. Bud grafting is to cut a...
