Description

A kind of engrafting method of grape
【Technical field】
The present invention relates to wine-growing and graft technology field, and in particular to a kind of engrafting method of grape.
【Background technology】
Grape important industrial crops in China is as agricultural, are promoted in many places.Grape breeding side Fado, plantation is relatively simple, and ripe grape receives an acclaim in fruit market, therefore is brought to the orchard worker of vast plantation grape Huge profit.Grape harvest is bred with graft technology, and not only scion is saved with material, survival rate is high, easy to operate, for big rule The wine-growing of mould is a kind of ideal planting technology.
Grape grafting is made of scion and stock, it has the characteristic for playing both concurrently and character is picked up from effect, scion Stable harvesting high-quality high-yield plant, thus maternal good characteristic can be kept, the resistance of stock, can strengthen kind cold-resistant, Non-irrigated, flooded, saline and alkaline and pest and disease damage ability, expands suitable kind of area of kind, in addition, grape grafting may also speed up to grape new product The calibrating and development of kind, accelerate the improvement to old vineyard.
Grape grafting at present uses stiff wood grafting, or green branch grafting, general survival rate to be formed with 50%-60%, survival rate more It is not high.
In recent years, deepening continuously with research, growth regulator is widely applied in agricultural production.Growth is adjusted Section agent can improve graft survival rate, promote the germination and growth buddered, in seeds such as walnut, jujube, citrus, apricots it has been reported that Although also there is the report applied to grape grafting in existing report, as application number CN201710509519.6 discloses a kind of thorn Portugal Grape grafting inorganic agent and preparation method thereof, it is made of following raw material:5~11 parts of rice vinegar, auxiliary liquid A4~8 part, dimension life Plain 2~6 parts of B12 parenteral solutions, 8~14 parts of withy, 5~9 parts of honey, 5~9 parts of sucrose, auxiliary liquid B1~5 part, heteroauxin 2~6 Part, 2~6 parts of methyl α-naphthyl acetate;But it is formulated complexity, and cost is higher, and using rear survival rate also only up to 65~70%.
【The content of the invention】
The goal of the invention of the present invention is:For above-mentioned problem, there is provided a kind of engrafting method of grape, it is described to transfer The survival rate of grape grafting significantly can be brought up to 75~80% by the method for connecing, and effectively shortened seedling-slowing stage, prevented nursery stock It is withered, promote the growth of grape.
To achieve these goals, the technical solution adopted by the present invention is as follows:
A kind of engrafting method of grape, comprises the following steps:
(1) scion gathers:Kind it is pure, without selection half on pest disaster and the vigorous result grape of robust growth Lignifying tender tip, is cut into simple bud section, wipes out 3/4 or whole blade, retains petiole, obtain scion;
(2) Root-stock selection:According to local climate and edaphic condition selection stock species, the stock of selection is affine with scion Power is strong, and institutional framework is consistent;
(3) grafting:Using cleft graft, while scion is grafted onto stock, graft union agent is applied to graft union week Enclose, graft union is then subjected to bondage with plastic film;The graft union agent is made of following raw material:Leech is extracted Liquid 8~10,1~3 part of compound amino acid, 2~6 parts of glucose;
(4) it is colonized:Graft union should be parallel to the ground during the grape grafting field planting that step (3) obtains, and avoids scion from taking root.
Further, in the step (1), scion collection carries out in the morning, removes whole blades after collection immediately, retains 0.5cm petioles.
Further, in the step (2), in cold district selection V. amurensis as stock, the cold-resistant of grape is improved, is resisted The ability of drought and pest and disease damage.
Further, in the step (3), the leech extracting solution is made in accordance with the following methods:Fresh leech is smashed to pieces, Add water saturated 70~80 DEG C of extractions of n-butanol, filtering, filtrate recycling n-butanol, relative density when being then concentrated into 60 DEG C 1.10~1.15, obtain leech extracting solution.
Further, in the step (3), the compound amino acid is mixed by following raw material:Methionine 5 ~10 parts, 3~5 parts of lysine, 1~3 part of threonine.
Further, in the step (3), the graft union agent is made in accordance with the following methods:By the amino acid and Glucose is sequentially added in the leech extracting solution and is uniformly mixed by weight to obtain the final product.
In conclusion by adopting the above-described technical solution, the beneficial effects of the invention are as follows:
The engrafting method of grape of the present invention, using graft union agent processing graft union in grafting procedures, can both promote Organization healing, significantly shortens the organization healing time, and can promote the growth of root system, can significantly increase grafting Survival rate, effectively shortens seedling-slowing stage, prevents nursery stock from drying up, and promotes the growth of grape.
