Abstract

The invention discloses a grafting method of camellia oleifera, and relates to the technical field of planting. The grafting method comprises the following steps: selecting root stocks; selecting grafting branches; cutting the selected root stocks; shaving fracture openings; poking up bark; pulling the shaved fracture openings; inserting the selected grafting branches; binding up connecting openings; applying venom. The problems that new seedlings are slow to grow up into a wood and fruits are slow to bear in the prior art of grafting and kind changing can be solved by the grafting method disclosed by the invention.

Description

The grafting method of oil tea

Technical field

The present invention relates to planting technology field, especially a kind of grafting method that can improve the tea oil tree of tea-oil tree yield.

Background technology

Oil tea, another name tea subtree, tea oil tree; Belong to Theaceae, evergreen dungarunga, because its seed can extract oil edible, therefore named; Tea oil tree tea seed output when the prime of life is high, and oil yield is high, but along with the increase of the tea oil tree age of tree, the quantity that tea oil tree produces tea seed is on a declining curve, and some tea oil trees also become poor oil tea tree gradually simultaneously; The problem of tree inferior is changed into tea oil tree for solution tea oil tree tea seed at advanced age yields poorly, at present, " large tree Grafting kind technology " is taked to improve the problem of low oil production tea tree in industry, this grafting method be utilize Camellia Oleifera Clones and new varieties become large tree in age, select spring tip branch then to carry out Grafting kind as stock; This method exists that new talent grows into forest slowly, slow problem of bearing fruit.

Summary of the invention

The object of this invention is to provide the grafting method of a kind of oil tea, it can solve, and the new talent that current existing Grafting kind technology exists grows into forest slowly, slow problem of bearing fruit.

In order to solve the problem, the technical solution used in the present invention is:

The grafting method of this oil tea, comprises the following steps:

A ,select stock: select that fertile, the seeding row spacing in forest land is neat, medium density, growing way vigorous in strong tea oil tree as stock, the first transaction of a day's business shape major branch that the logical direct light of every strain Root-stock selection 3 ~ 4 is sliding;

B ,select grafting: select the annual shoot full with axillalry bud of high yield and high quality, growth stalwartness to make grafting twig;

C ,disconnected stock: the stock chosen overhead 40 ~ 80 centimeters are sawed-off, during disconnected anvil, note preventing stock cortex from tearing, every strain stays 2 ~ 3 major branches be used as vegetative shoot and shelter from heat or light, and all the other branches are all removed;

D, cut fracture: scabble saw kerf with grafting knife, bevel is high outer low in wanting, slightly gradient;

E, choose bark: by grafting twig size and length, with single-edge blade at stock incision position, down parallelly cut two cuttves, deeply reach xylem, then bark provoked and pull open;

F, draw cut mouth: use single-edge blade at grafting twig leaf bud reverse side from bastem slightly below, the tangent plane of long 2 cm of straight down oblique pull one, tangent plane reaches xylem deeply;

G, grafting branch: in the stock bark groove pull open grafting twig aligning formation layer insertion E step, then cover on the short tangent plane of grafting by the bark that stock is provoked, a stock connects 1 ~ 3 branch;

H, colligation interface: with the good interface of film strip colligation from bottom to up that pulling force is stronger; During colligation, note preventing grafting from moving;

I, painting venom: after grafting, with being moistened with the pen of venom below interface, draw a circle around stock, and prevent ant from encroaching on the position of grafting, so far, grafting procedures completes.

Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:

1, the present invention adopts the grafting method of branching grafting, make advanced age tea oil tree output reduce, problem that the tea seed quality of output declines solved, and tea oil tree is radiated the vigour of youth;

2, the new tea oil tree that grafting method of the present invention obtains is born fruit soon, and fruit yield is high.

Embodiment

Below in conjunction with embodiment, the present invention is further described:

The grafting method of this oil tea, comprises the following steps:

A ,select stock: select that fertile, the seeding row spacing in forest land is neat, medium density, growing way vigorous in strong tea oil tree as stock, the first transaction of a day's business shape major branch that the logical direct light of every strain Root-stock selection 3 ~ 4 is sliding;

B ,select grafting: select the annual shoot full with axillalry bud of high yield and high quality, growth stalwartness to make grafting twig;

C ,disconnected stock: the stock chosen overhead 40 ~ 80 centimeters are sawed-off, during disconnected anvil, note preventing stock cortex from tearing, every strain stays 2 ~ 3 major branches be used as vegetative shoot and shelter from heat or light, and all the other branches are all removed;

D, cut fracture: scabble saw kerf with grafting knife, bevel is high outer low in wanting, slightly gradient;

E, choose bark: by grafting twig size and length, with single-edge blade at stock incision position, down parallelly cut two cuttves, deeply reach xylem, then bark provoked and pull open;

F, draw cut mouth: use single-edge blade at grafting twig leaf bud reverse side from bastem slightly below, the tangent plane of long 2 cm of straight down oblique pull one, tangent plane reaches xylem deeply;

G, grafting branch: in the stock bark groove pull open grafting twig aligning formation layer insertion E step, then cover on the short tangent plane of grafting by the bark that stock is provoked, a stock connects 1 ~ 3 branch;

H, colligation interface: with the good interface of film strip colligation from bottom to up that pulling force is stronger; During colligation, note preventing grafting from moving;

I, painting venom: after grafting, with being moistened with the pen of venom below interface, draw a circle around stock, and prevent ant from encroaching on the position of grafting, so far, grafting procedures completes.
