Abstract
The invention discloses a Jatropha curcas grafting method which includes preparation steps and grafting steps. The preparation steps include: repeatedly applying organic fertilizers to female parent trees and grating trees of Jatropha curcas in late autumn and early winter seasons, keeping water supply for the female parent trees one month before ear trimming prior to stopping the water supply, generally spraying leaf fertilizers on the female parent trees and the grafting trees 5-7 days before ear trimming, and performing disinfection treatment on knives and tools used for grafting before grafting; the grafting steps include: adopting a deep-V grafting method for grafting; binding grafting parts; performing injury flow treatment and eliminating exclusiveness; cutting stocks and removing sprouts prior to water and fertilizer management. Through a series of key steps of adopting the deep-V grafting method, performing injury flow treatment, eliminating exclusiveness and the like, survival rate of grafting is greatly increased, and the survival rate can be up to 100%; the Jatropha curcas grafting method is simple to operate, easy to learn and master and capable of realizing mass production; a superior family garden which is bumper, stable and high in yield, high in oil yield and high in stress resistance can be obtained after good scions are grafted.
Description
Technical field
The present invention relates to plant reconfiguration, change kind of a technology, be specifically related to a kind of grafting method of Jatropha curcus.
Background technology
Jatropha curcus is bioenergy plant, and short owing to developing the time, current Jatropha curcus is also in wild self-sow state, and low yield, at every mu about 200 kilograms, seriously constrains the development of Jatropha curcus.
In order to improve the output of Jatropha curcus, people attempt utilizing grafting to carry out plant improvement to Jatropha curcus.But; because Jatropha curcus belongs to half carnification Euphorbiaceae woody plant; its root, stem, bar, branch, leaf, bud all contain a large amount of protein type milk; bacteria breed breeding is exceedingly fast, and causes the affine function of in vitro callus of Jatropha curcus cuttings greatly to decline, simultaneously; because existing grafting method is too simple; be difficult to the condition meeting Jatropha curcus graft union growth needs, cause Jatropha curcus graft survival rate very low, cannot accomplish scale production.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of Jatropha curcus grafting method, overcomes that the graft survival rate that prior art exists is low, the defect that cannot accomplish scale production.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of Jatropha curcus grafting method, it is characterized in that, comprises preparation process and grafting step;
Described preparation process comprises:
A1, at the beginning of autumn Mo, winter season to Jatropha curcus stock tree and grafting tree heavy dressing fertilizer;
A2, kept moisture supply before one month at Jatropha curcus stock tree clip fringe bar, stop subsequently watering;
A3, before clip fringe bar 5 ~ 7 days, to Jatropha curcus stock tree and the general spray foliage fertilizer of grafting tree;
To grafting cutter, apparatus disinfection before A4, grafting;
Described grafting step comprises:
S1, grafting: clip fringe bar from Jatropha curcus stock tree, on Jatropha curcus grafting tree stock, next wedge-shaped slot is cut from top to bottom with grafting knife, the length of this wedge-shaped slot is 1.5 ~ 2 times of stock cross section diameter, with grafting knife, the grafting end-grain cutting of fringe bar is gone out the tapered end of coincideing with this wedge-shaped slot, the tapered end of fringe bar is inserted in the wedge-shaped slot of stock as early as possible, make stock wedge-shaped slot form layer and form the concordant laminating of layer with fringe bar tapered end;
S2, bondage: to the tight tighten of grafting part bag, keep grafting part trunk temperature between 20 DEG C ~ 30 DEG C;
S3, bleeding process and the process of elimination rejection: spray to grafting wound location with copper nobleness 500 ~ 1000 times of dilutions after grafting, spray in 5 ~ 7 days once, connects spray three times; To the tree general spray growth promoter of body 500 ~ 1000 times of dilutions after grafting, spray in 5 ~ 7 days once, connects spray three times;
S4, cut anvil except sprouting: after fringe bar survives, cut off other branch on stock except scion in time;
S5, water and fertilizer management: after grafting survival, the initial stage controls water in right amount.
In Jatropha curcus grafting method of the present invention, in step s3, the noble concentration of copper is 800 times of dilutions.
In Jatropha curcus grafting method of the present invention, in step s3, growth promoter concentration is 800 times of dilutions.
In Jatropha curcus grafting method of the present invention, in step s3, described growth promoter is No. 1, green core gold, powerful root-growing agent or root-inducing powder.
Implement Jatropha curcus grafting method of the present invention, compared with the prior art, its beneficial effect is:
1., by adopting dark V grafting, bleeding process and eliminating a series of committed steps such as rejection process, graft survival rate is improved greatly, and survival rate reaches as high as 100%; Simple to operate, be easy to learning and mastering, can large-scale production be realized;
2., in grafting after improved seeds scion, the superior families garden of high yield, stable and high yields, high oil recovery, strong stress resistance can be obtained.
Embodiment
Below in conjunction with embodiment, the invention will be further described.
Preparation process and grafting step is comprised at Jatropha curcus grafting method of the present invention.Wherein:
Preparation process comprises:
1, at the beginning of autumn Mo, winter season to Jatropha curcus stock tree and grafting tree heavy dressing fertilizer.This step can be fostered and apply fertilizer tree vigo(u)r, and make stock, fringe bar nutritious, sprout is full.
2, kept moisture supply before one month at Jatropha curcus stock tree clip fringe bar, stop subsequently watering, in order to avoid because bleeding affects survival rate during grafting.
3, before clip fringe bar 5 ~ 7 days, to Jatropha curcus stock tree and the general spray foliage fertilizer of grafting tree, make the inner nutrient allocation of its branch evenly, rationally, comprehensively.
4, grafting is front to grafting cutter, apparatus disinfection.
Grafting step comprises:
S1, grafting: adopt dark V word grafting, clip fringe bar from Jatropha curcus stock tree, on Jatropha curcus grafting tree stock, next wedge-shaped slot is cut from top to bottom with grafting knife, the length of wedge-shaped slot is 1.5 ~ 2 times of stock cross section diameter, with grafting knife, the grafting end-grain cutting of fringe bar is gone out the tapered end of coincideing with this wedge-shaped slot, the tapered end of fringe bar is inserted in the wedge-shaped slot of stock as early as possible, make stock wedge-shaped slot form layer and form the concordant laminating of layer with fringe bar tapered end.Ensure during grafting that wedge-shaped slot that the tapered end of fringe bar forms layer and stock forms layer smooth, concordant, make both comprehensively, fit tightly.
S2, bondage: to the tight tighten of grafting part bag, keep grafting part trunk temperature between 20 DEG C ~ 30 DEG C.This step reduces the moisture evaporation of stock, fringe bar, impels the contiguity of grafting part forming surface, is conducive to the healing of grafting part callus.
S3, bleeding process and the process of elimination rejection: after grafting, with copper height Yet-have 500 ~ 1000 times of dilutions, (such as can adopt copper height Yet-have 600 times of dilutions, 800 times of dilutions, 900 times of dilutions etc.) is sprayed to grafting wound location, spray in 5 ~ 7 days once, connects spray three times; To the tree general spray growth promoter of body 500 ~ 1000 times of dilutions (such as can adopt growth promoter 600 times of dilutions, 800 times of dilutions, 900 times of dilutions etc.) after grafting, spray in 5 ~ 7 days once, connects spray three times, to promote that protoplasm flows, improve cell viability, increase survival rate.Growth promoter can adopt and include but not limited to No. 1, green core gold, powerful root-growing agent, root-inducing powder.
S4, cut anvil except sprouting: after fringe bar survives, cut off other branch on stock except scion in time, make nutrient, moisture centralizedly supply fringe bar.
