Abstract
The invention discloses a fast growing method for bud grafting of a barbadosnut, which comprises a bud grafting method and a management step after the bud grafting, wherein the bud grafting method consists of the steps of scion collecting, stock cutting, bud cutting, bud inserting and binding; and the scion collecting is to collect a branch of the annual or biennial barbadosnut with lignification, half lignification, plump eyes and no diseases and inset pests; leaves on the branch are removed in time when the branch is cut from the barbadosnut; and the branch is wrapped by a wet towel and so on for standby. The bud grafted by the method sprouts ten days earlier and grows quickly; the basic diameter, length and leaf number of a new branch by the method can improve 40.3-50 percent, 150-208.8 percent and 35 to 55 percent respectively compared with those of new branches by other methods after 70 days of the bud grafting.
Description
Technical field
The present invention relates to a kind of bud grafting technology, particularly the Jatropha curcas bud grafting is germinateed and quick technology of growing fast.
Background technology
Jatropha curcas (Jatropha curcas L.), have another name called the little seeds of a tung oil tree, cream paulownia, black Quillaia saponaria etc., be Euphorbiaceae leprosy Pterostyrax (Euphorbiaceae) machaka or dungarunga, high by 2～5 (or 7) rice originates in tropical America, now is widely distributed in torrid areas, the world, be distributed in ground such as Yunnan, Sichuan, Guangxi, Guangdong, Hainan in China, maximum with Yunnan Province, take second place in Sichuan, often concentrates on by riverbank, the residence, the roadside; Because of cauline leaf is poisonous, livestock does not eat, and often makes hedge cultivation, as " the biological fence " of vegetable plot, crop land.The suitable scope of giving birth to of Jatropha curcas is wide, and below 1600 meters, the area of annual mean temperature more than 17 ℃ be the energy normal growth all, and certain cold resistance is arranged, and can restrain oneself-5 ℃ of short duration low temperature at southern height above sea level, and property happiness high temperature and florescence need the place of arid.Jatropha curcas is not selected soil, can be called as " strong plant " in India in very barren wasteland growth.In tea oil, wilson dogwood oil, Jatropha curcas oil, tung oil, vegetable seed wet goods China several base stock vegetable oil in south, the economic characters that Jatropha curcas oil is produced biodiesel are the highest; Financial cost, ecological functions and the social function of comprehensive raw material, Jatropha curcas position example the first becomes the extremely oil plants of people's concern jointly with pencil tree, wilson dogwood, idesia, Chinese pistache etc.At present, the Jatropha curcas industry has obtained the attention of height, and industry develops rapidly.But Jatropha curcas planting technology, administrative skill etc. also are in the seed selection of developing stage, particularly improved seeds, the big face popularization of excellent strain etc. and also are in the exploratory stage.Therefore, proceed from the reality, the bud grafting technology of the suitable Jatropha curcas of exploitation for promoting the Jatropha curcas excellent strain quickly and efficiently, ensures that the curcas biological diesel oil industry is quick, developing in a healthy way has great real value and meaning.
Summary of the invention
One of purpose of the present invention provides the method that a kind of Jatropha curcas bud grafting is germinateed and grown fast fast.
This and other purpose of the present invention will further embody and set forth by following detailed description and explanation.
Fast-growing method for grafting bud of Jatropha Curcas of the present invention, comprise management process after budding method and the bud grafting, wherein budding method is formed by adopting scion, cut stock, cut the bud sheet, insert the bud sheet and bundling step, described to adopt scion be to gather the lignification of life in 1 year or life in 2 years or semi-lignified, full, the no damage by disease and insect Jatropha curcas of eye branch, in time removes blade behind the clip and wrap standby with wet towel etc.The described stock of cutting is to select for use the little seeds of a tung oil tree tree of diameter 1.5-10cm as stock, and the liftoff footpath of grafting part highly be 5-30cm, at the stock cortex with grafting knife rip cutting two cuttves from bottom to top, edge of a knife top intersection.Knife edge length is 1.5-5cm, and width is 1.2-3.5cm, and the degree of depth is for just reaching xylem.The described bud sheet of cutting is to select scion middle part or the full bud in top to cut to get the bud sheet, 1-3cm place flat face is by about 30 ° angle cutter of splaying above eye, knife edge length is controlled at 2-6cm, then below eye the 1-3cm place perpendicular to the straight partial application of branch, take out the bud sheet and remove xylem on the bud sheet, the bud sheet is whittled into about 1-3cm * 1.5-4.5cm pane.Described slotting bud sheet is to wipe the resin that flow out at stock grafting mouth place, tear the bark on the grafting mouth, separate the cortex that grafting mouth top combines with the stock xylem, the bud sheet of cutting is inserted the grafting mouth, the bud sheet is close on the stock, and the marginating compartment 1-10mm of bud sheet and grafting mouth.Described binding is the bark of tearing on the stock to be pasted go back, and it is pressed on the bud sheet, answers watt type with the film of wide 1-3cm from bottom to top from the about 1-3cm in grafting mouth below and closely bundlees the grafting mouth.
In fast-growing method for grafting bud of Jatropha Curcas of the present invention, comprise separating in management process after the described bud grafting and manage and protect step after tying up, saw anvil and grafting, describedly separate that to tie up be after bud grafting 15-25 days, untie the film of binding, and cut the stock cortex that is attached on the bud sheet, the bud grafting sheet is exposed.Described saw anvil be separate tie up 3-10 days after, apart from bud grafting mouth top 2-8cm place, the saw kerf inclined-plane should be at 45 back to the grafting mouth, the trees saw anvil that the bud sheet is survived, and paint (or paraffin) and smear and saw the anvil mouth.Manage and protect step after the described grafting for other bud step on the stock of in time erasing, according to trees growing way situation, the step and before rainy season, the Jatropha curcas bud was sprouted of mixing clearly, loosen the soil and apply fertilizer; (there is not specific (special) requirements with 2-3 Baume degrees lime sulfur, the commercially available prod all can be used, spray tree 1-3 time, after rudiment, become 1000 times of liquid with 20 weight % triadimefon wetting powder thin ups, 70 weight % thiophanate methyl wetting powder thin ups become 1000 times of liquid controls, and 15 days once, sprays 2-3 prevention and elimination of disease and pests continuously.
The advantage of the inventive method: the bud of grafting germinates early, and germinating time can shift to an earlier date 10 days; The blastogenesis of grafting is long very fast, compares after 70 days with bud grafting, adopts base footpath, length and the number of blade of the inventive method young sprout can improve 40.3%-50%, 150%-208.8% and 35%-55% respectively.
Below further specify the present invention by specific embodiment, but embodiment only be used for the explanation, can not limit the scope of the invention.
