Abstract
The invention relates to the technical field of grafting, and particularly discloses a grafting method for Chinese torreya. The grafting method comprises the following steps of stock trunk cutting, scion preparation, grafting, soil covering and final-period management. Compared with a traditional grafting method for Chinese torreya, grafted seedlings obtained through the grafting method grow rapidly and are high in survival rate, particularly, the grafting survival rate of small Chinese torreya in Yi County of Anhui Province reaches up to 95%, rapid propagation of the small Chinese torreya is effectively ensured, and the grafting method is of great significance in popularization of Chinese torreya varieties with good quality.
Description
Technical field
The present invention relates to graft technology field, be specifically related to a kind of grafting method of Chinese torreya.
Background technology
Chinese torreya, calling Chinese Chinese torreya, is Chinese yew order, taxaceae, Torreya aiphyllium, is rare in the world economic tree, it is mainly grown in the comparatively moistening area of southern china, and Chinese torreya is mainly distributed in the ground such as Chinese Yi County, Zhuji, zhejiang, Fuyang at present.Chinese torreya normally adopts grafting to cultivate, and the growth and maturity phase is 3 years, and fruit is nut, and nutritive value is high, is the senior timber that is used to make chessboard at East Asian countries' Chinese torreya wood.
Common Chinese torreya kind has roundlet Chinese torreya, millet Chinese torreya, long Chinese torreya, wooden Chinese torreya, goat's horn Chinese torreya and convulsion Chinese torreya etc., wherein millet Chinese torreya is one of foremost Chinese torreya, has another name called Buddhist monk's Chinese torreya, and Buddhist monk's Chinese torreya belongs to roundlet Chinese torreya class, particle is short and justify, seed coat is thin and easily de-, and palatable crisp, is the splendid treasure kernel of quality in Chinese torreya, but millet Chinese torreya is in the time that grafting is cultivated, due to the jewelry, expensive clothing and other valuables of its scion, cause graft survival rate lower, affect widely the popularization of millet Chinese torreya.
Summary of the invention
The grafting method that the object of this invention is to provide the Chinese torreya that a kind of graft survival rate is high, the method is simple, easily realizes.
For achieving the above object, the technical solution used in the present invention is: a kind of grafting method of Chinese torreya, comprises the following steps:
A) stock cutting strunk: select mid-March-mid-April the Chinese torreya seedling that 2-3 is raw, blocked and obtain stock apart from 4-6cm place, ground, with cleft grafting cutter gently from stock the middle part of end section vertically split down, split the long 3-4cm of mouth;
B) scion is prepared: intercept annual side shoot as scion from colory Chinese torreya elite stand, and spike length 8-10cm, the blade of scion truncated position is removed, and the truncated position of scion is whittled into wedge shape, the long 2-3cm in wedge shape inclined-plane;
C) grafting: the mouth of splitting of gently breaking stock upper end with have gentle hands into two with one's hands, then the tapered end of scion is inserted and split mouth, the wedge shape inclined-plane of scion exposes stock 0.1-0.2cm, then with plastic film by stock and the tight colligation of scion interface, a skew back face of described scion becomes face to fit tightly with the fracture-shaped of stock;
D) earthing: with yellow soil, grafting is covered to scion and only has the height of 1/3-2/3 to be exposed outside.
E) management: remove in time the weeds of the new rudiment of grafting and periphery, used to grafting and execute disposable fertilizer every 2-3 days, the urea that each fertilizer using is 0.2%-0.3% for 100-200ml concentration, after seedling to be grafted survives, removes earthing.
The beneficial effect that technique scheme produces is: compared with traditional Chinese torreya grafting method, the grafting that the disclosed technical method grafting of employing the application obtains grows soon, survival rate, especially for the millet Chinese torreya in area, Yi County, its graft survival rate is up to more than 95%, effectively guaranteed the Fast-propagation of millet Chinese torreya, this popularization for the Chinese torreya kind of high-quality is significant.
As further preferred version: described scion is the annual side shoot on millet Chinese torreya, Chinese torreya seedling is millet Chinese torreya seedling, the diameter of millet Chinese torreya seedling is 1.0-1.2cm, technique scheme goes for the Chinese torreya grafting of multiple kind, be particularly useful for the grafting of millet Chinese torreya, graft survival rate is high, the millet Chinese torreya seedling that when grafting, preferred diameter is 1.0-1.2cm, this is the preferred plan that applicant obtains through verification experimental verification for many years, when the diameter of millet Chinese torreya seedling is excessive, survival rate is low, and final-period management difficulty is large, when diameter is too small, the growth of grafting is very slow, be difficult to meet market demand.
Further, described Chinese torreya seedling and scion are being cultivated, when grafting, all adopt the sunshade of sunshade yarn, the light transmittance of sunshade yarn is 40-50%, in addition, described grafting is fine, grafting when dew is dry, the survival rate of Chinese torreya grafting and the upgrowth situation of grafting are subject to the impact of external environment larger, put up a shed at grafting place, and lay the sunshade yarn that light transmittance is 40-50%, preferably, temperature in scaffolding is 10-20 ℃, under this condition, the growth of grafting is fast, survival rate is high, in addition, preferably be chosen in cool place, the mountain region of high humidity arranges grafting nursery.
In fact, expose the incision part of scion, can make like this formation layer contact-making surface of scion and stock large, can effectively prevent that moisture evaporation and earth from falling into otch impact healing, preferably, described grafting is with adopting yellow mud to apply the otch that is exposed outside of scion before plastic film colligation, applies by yellow mud the interface quickly-healing that scion otch appears place and can effectively guarantee scion, thus survival rate and the growth rate of raising grafting.
Further, described Chinese torreya seedling is that male, described scion is tassel.
Described scion is wrapped up otch with plastic film after intercepting immediately, and In Shade placement, time to be grafted, take out again, in order to improve the grafting efficiency of Chinese torreya, personnel with good conditionsi can directly be stored in large quantities of scion in the refrigerator of 5-10 ℃, so both effectively the water loss in scion affected the survival rate of grafting, had the metabolism that can delay scion, guaranteed the freshness of scion.
