Problems solved by technology

However, due to the short time of artificial domestication, cocoa tea has not been well adapted to the cultivation environment, and the survival rate of cuttings is low. Instead, the method of grafting is used to propagate cocoa tea.

Embodiment 1

[0025] Cocoa No. 1 is grafted with Yunnan big leaves from the end of autumn to February of the following year. The steps are as follows:

[0026] ①Fringe retention in the parent garden: The ears should be retained from August. After about five months of growth, the branch length reaches 30-40cm, and the internodes are longer, which is conducive to ear cutting.

[0027] ②Select 15-year-old Yunnan Daye tea garden plants as rootstocks.

[0028] ③ Select and cut the scion: select strong branches, the scion branch should have a bud and a leaf, the branch length is 4-6cm, the length below the leaf node should be at least 3.5cm, and the length above the leaf node should be 0.5cm. The grafting knife cuts obliquely into the xylem on the other side facing the bud leaf and then turns to cut down to the bottom. The grafting knife cuts obliquely into the xylem at the side slightly below the bud leaf and then turns down to cut the scion into an inverted long triangle cone. The scion is graf...

[0041] ③ Select and cut the scion: select strong branches, the scion branch should have a bud and a leaf, the branch length is 4-6cm, the length below the leaf node should be at least 3.5cm, and the length above the leaf node should be 0.5cm. The grafting knife cuts obliquely into the xylem on the other side of the bud leaf and then turns to cut down to the bottom.

Abstract

The invention discloses a cocoa tea great parental stock grafting method of cultivation, comprising: (1) the choice of the grafting time: the grafting time is from the late autumn or the early winter to the February of the next year; (2) the choice of parental stock: a 5-15 year-old pu erh tea plant growing in tea garden with broken parental stock and repaired fault plane is selected as the parental stock; (3) the choice of cion of the cocoa tea: the cion of the cocoa tea is the clonal fine variety of cocoa tea and the cion wattle is the lignified wattle born in the last year or the semi-lignified wattle born in the current year; (4) cion cutting: the cut cion is immerged into the auxin accelerating the generation of callus; (5) grafting: the cion is engrafted into the parental stock; (6) bag-covering colligating: the parental stock connected with the cion is colligated by a transparent and enduring plastic bag; (7) an awning is established by a rack to protect; (8) the fallow and the supplement of water; (9) the remove of bag: the plastic bag and a sunshade net can be gradually removed after the cion survives. The method of cultivation of the invention has a high survival rate and a high garden forming speed, with unchanged basic property of cocoa tea, thereby increasing the quality of theanine.

Description

technical field [0001] The invention relates to a breeding method of cocoa tea and a rapid gardening technique. Background technique [0002] The two cultivated tea trees [(C. sinensis (L.) O.Ktze and Pu-erh tea C. assamica (Mast.) Chang)] are closely related to cocoa tea Camellia ptilophylla Chang, and they both belong to the subgenus Camellia. Tea group plants. Tea and Puerh tea made from buds and leaves mainly contain caffeine. For thousands of years, people planted tea, made tea, and drank tea. Tea has become a worldwide beverage because drinking tea can excite the nerves and improve work efficiency. At the same time, drinking tea also has health effects such as helping digestion. Cocoa tea is different from tea and Pu'er tea. Its buds and leaves only contain about 4% theobromine, and it does not contain caffeine at all. Except that cocoa tea contains theobromine, which is different from cultivated tea, the rest of the biochemical components are consistent with cultiva...
