Problems solved by technology

[0007] The above-mentioned several grafting methods are highly pertinent in actual application, have high requirements for rootstocks and scions, and have limited material selection ranges. They can only use annual branches (especially tender branches) as scions for grafting within a specific period of time, while for second-stage Branches and three-stage branches are not applicable, and the grafting time is limited, and can only be grafted within a certain season or a shorter period of time. It is not suitable for grafting and breeding of Kudingcha, especially in Kudingcha fine seed gardens and mother forests. In terms of construction, it is difficult to meet the breeding requirements

Embodiment 1

[0032] Embodiment 1, carry out stock bed grafting and breeding in growth period (usually in 4~10 months), its steps are as follows:

[0033] ①. Scion selection and cutting: Select the annual lignified large-leaf holly Kudingcha robust branch with a diameter of about 0.8 cm, cut it to a length of 5 cm as scion 1, leave a bud and a leaf at the top (only the petiole is left), and the grafting knife is along the opposite side of the leaf bud Cut at 0.5 cm below, the length of the knife edge is 3 cm deep to the center of the pith, forming the scion bevel 2, and a scion bevel 3 with a length of 0.5 cm is cut at the lower end of the other side of the scion bevel;

[0034] ②. Select and cut rootstock: directly select 1 to 2-year-old big-leaf holly Kudingcha seedlings in the nursery as the rootstock 4, the neck is about 1.2 cm thick, and the rootstock cannot be lifted. Cut it on the rootstock about 8 cm high from the ground. Go out long 4 centimeters and be deep to the stock cut surfac...

Embodiment 2

[0039] Embodiment two, carry out anvil grafting and breeding with two section branches in dormant period (usually in November~March next year), its steps are as follows:

[0040] ① Select and cut the scion: Select the second section of 0.8 cm thick Kudingcha branch, cut it to a length of about 5 cm as the scion 1, of which the annual branch is about 1.5 cm long, the biennial branch is about 3.5 cm long, and cut out about 3 cm long at the lower end of the biennial branch Deep to the scion beveled surface 2 of the pith center, cut a scion beveled surface 3 with a length of about .05 centimeters at the opposite side lower end of the scion beveled surface;

[0041] ②Choose and cut the rootstock: choose 1 to 2-year-old Ilex kudingcha artificially seeded with a neck diameter of about 1.2 cm as the rootstock 4, dig it up from the nursery, and cut it short at a place 3 cm above the ground diameter, then select The smooth and straight side of the cortex is cut down from the 0.5 cm from...

Abstract

A graft technique for reproducing lectuce tea tree includes cutting off a branch of pure lectuce tea tree as scion with 4-6 cm in length, sharpening its one end from both sides, choosing a pure lectuce tea tree with (1-2)-year old as stock, cutting to form an incision, grafting, binding and cultivation. Its advantages are high adaptability and survival rate, high growth speed, and high tea quality.

Description

【Technical field】 [0001] The invention relates to a breeding method of kudingcha, in particular to a method for grafting and breeding used for the construction of kudingcha fine seed gardens and mother forests to produce excellent clones and excellent kudingcha seedlings. 【Background technique】 [0002] There are more than 20 kinds of plants known as Kudingcha, but there are only two kinds of pure Kudingcha with long historical records, one is Ilex Ilexa Thunb (its Latin scientific name is Ilex Iatifolia Thunb), and the other is Kudingcha. One is Kudingcha holly species (its Latin scientific name is Ilex Kudingcha Tseng); the Kudingcha made with them has unique efficacy, obvious pharmacological and health care effects, and good greening and beautifying benefits; It is an excellent tree species for building an ecological public welfare forest; its growth adaptability is strong, and Kudingcha can be planted wherever tea trees are suitable for growth. However, because Kudingch...
