Abstract

The invention provides a Cephalotaxus sinensis grafting method. By means of rational selection and special treatment of stocks and scions and perfect management after grafting, the purposes of increasing the grafting survival rate and rapidly forming are achieved.

Description

A kind of caephalotaxus sinensis grafting method

Technical field

The present invention relates to the gardening field, be specifically related to a kind of grafting method of caephalotaxus sinensis.

Background technology

Caephalotaxus sinensis (Cephalotaxus) claims caephalotaxus sinensis China fir, Chinese caephalotaxus sinensis China fir again, belongs to Cephalotaxaceae shrub or dungarunga, and bark grey or brown are laminar and peel off.Blade strip lanceolar, with luxuriant foliage and spreading branches in leafy profusion anti-pruning, surperficial bottle green is glossy, and there are two stomatal bands at the back side, the seed oval, also bar shaped, straight usually, seldom little curved, gradually sharp, long 2-5cm, wide 3mm.The base portion subcircular, several stockless, above green, below stomatal band white, just be with wide approximately 3-4 times than green.Bloom April, seed maturation in October next year, 2-5 be born in total stalk top.

Caephalotaxus sinensis mainly is distributed in the torrid zone and south subtropics, scattered mountane rain forest or cheuch, next door, mountain stream weather humid region in height above sea level 700-1200 rice.Its seedling treelet needs certain sheltering from heat or light, and the back light requirement of growing up is not afraid of increase, and it is strong to set rudiment power greatly.In recent years, caephalotaxus sinensis is because its uniqueness tree-like, the application of being planted gradually in afforestation.Because its open-pollinated rate is low, the result is few, adopts vegetative propagation usually, and mostly is cottage propagation.Because growth of cuttage seedlings is slow, can not obtain required tree-likely fast, therefore cause and can not promote fast.

Summary of the invention

The technical problem that the present invention mainly solves provides fast, the effective caephalotaxus sinensis propagation method of a kind of moulding.

For solving the problems of the technologies described above, the technical solution used in the present invention is:

A kind of grafting method of caephalotaxus sinensis is characterized in that, comprises the steps

(1) stock is selected: select robust growth, no damage by disease and insect and mechanical damage, height of seedling 3-4m, the thick caephalotaxus sinensis tree in 15cm of base portion stem are done stock; The 6cm place clips stock top on distance grafting interface top, erases lateral bud simultaneously;

(2) scion is selected: the adult elite stand of select age of tree 10-15, stablizing, getting bumper crops, get its 1 year living side shoot, and require about the thick 1.5cm of scion spike length 15cm; Preceding 1 week of scion collection branch is carried out girdling and handle, the concrete operations mode is that the 4cm place is with lancinating half-turn below branch, and 2cm cuts half-turn again at the rightabout that cuts half-turn at interval;

(3) grafting: grafting time selects annual late March to early April; Blade in the scion is removed 1/3-2/3, in the oblique partial application in scion bottom, Cheng Maer shape, and at otch back side de-epithelization; Select stock middle and lower part 3-4cm to go out as grafting part, take off the epidermis piece more bigger than scion otch, expose the xylem at stock grafting position; The scion cutting part is earlier dipped in 20s in 800 times of carbendazim liquid, immerse in the IAA200ppm+ gibberellin 100ppm root-growing agent solution again and soak 30min, the xylem that scion otch and stock are exposed is adjacent to subsequently, with film wrapped and tighten;

(4) managing after grafting: carry out daily water and fertilizer management, should be noted that when meeting rainfall that wrapping up the position does not want ponding, when sprout tillers occurring around the stock grafting position, the removal of tiller in time; Then should adopt conventional prophylactico-therapeutic measures in time to handle as the twig disease insect pest; Usually the grafting wound can heal in 3 months fully, and the grafting twig growth is normal; Remove the film of tying up before going into the winter.

The invention has the beneficial effects as follows:

(1) the present invention has carried out rational selection to the specification of stock and scion, can improve graft survival rate 35-40% than the grafting specification of its common employing, and moulding is fast, can be used for greening after 1 year and plant.

(2) before the grafting branch being carried out girdling and handle, branch nutrition is assembled, is one of key that improves survival rate.

(3) kept maternal good hereditary capacity, can enter speed rapidly and give birth to the phase, solid ahead of time.

Embodiment

Below preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.

The embodiment of the invention comprises:

A kind of grafting method of caephalotaxus sinensis is characterized in that, comprises the steps

(1) stock is selected: select robust growth, no damage by disease and insect and mechanical damage, height of seedling 3-4m, the thick caephalotaxus sinensis tree in 15cm of base portion stem are done stock; The 6cm place clips stock top on distance grafting interface top, erases lateral bud simultaneously;

(2) scion is selected: the adult elite stand of select age of tree 10-15, stablizing, getting bumper crops, get its 1 year living side shoot, and require about the thick 1.5cm of scion spike length 15cm; Preceding 1 week of scion collection branch is carried out girdling and handle, the concrete operations mode is that the 4cm place is with lancinating half-turn below branch, and 2cm cuts half-turn again at the rightabout that cuts half-turn at interval;

(3) grafting: grafting time selects annual late March to early April; Blade in the scion is removed 1/3-2/3, in the oblique partial application in scion bottom, Cheng Maer shape, and at otch back side de-epithelization; Select stock middle and lower part 3-4cm to go out as grafting part, take off the epidermis piece more bigger than scion otch, expose the xylem at stock grafting position; The scion cutting part is earlier dipped in 20s in 800 times of carbendazim liquid, immerse in the IAA200ppm+ gibberellin 100ppm root-growing agent solution again and soak 30min, the xylem that scion otch and stock are exposed is adjacent to subsequently, with film wrapped and tighten;

(4) managing after grafting: carry out daily water and fertilizer management, should be noted that when meeting rainfall that wrapping up the position does not want ponding, when sprout tillers occurring around the stock grafting position, the removal of tiller in time; Then should adopt conventional prophylactico-therapeutic measures in time to handle as the twig disease insect pest; Usually the grafting wound can heal in 3 months fully, and the grafting twig growth is normal; Remove the film of tying up before going into the winter.

The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes description of the present invention to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
