Abstract
An auxin-regulated bud grafting method for tree features that the auxin concentration at the bud-grafted position of tree is lowered by artificial treatment to speed up the wound healing and promote the growth of grafted bud. Its advantages are high survival rate (more than 95%), no damage to the stock, and robust grafted branch.
Description
The invention belongs to trees graft technology field, is the auxin concentration by manual adjustment bud grafting position, thereby increases substantially the method for bud take.
Present known trees bud grafting method exists that survival rate is low, to survive the back growth rate slow, the impaired shortcoming of stock tree body nutritional status.Its reason is that the growth of trees all is controlled by the distribution of growth hormone in the tree body, trees grow up in order to grow tall, the growth hormone of distributing to each growing point relatively lacks, the growth hormone of particularly distributing to wooden top is optium concentration, thereby make apical growth the fastest, Here it is so-called " apical dominance ".And the grafting point of bud grafting all is certain position in the middle of branch, its auxin concentration is relatively high, and former the sprouting at these positions just is in resting state originally, how could allow external bud sprout easily? add the factor of the allosome repulsion of stock tree body, even skilled grafting worker, the survival rate of bud grafting is not high, and particularly those graft survival rates are originally with regard to low seeds, and this problem more looms large.People are in order to improve the survival rate of bud grafting, be everlasting and cut down most of tree crown immediately after the bud grafting, because bud grafting is normally carried out in the fall, this moment, tree crown still was in luxuriant foliage and spreading branches in leafy profusion, the stage that the photosynthesis of blade is very strong, if cut down most of tree crown, the nutritional status of tree body is had a strong impact on, thereby budder poor growth after causing, in addition, for the still unskilled personnel of those graft technologies, buddering after cutting down tree crown does not survive, and allows stock tree body be inflicted heavy losses in vain.
The objective of the invention is provides a kind of regulating type bud grafting method of tree growth hormone to society, overcoming the shortcoming of known bud grafting method, thereby increases substantially the growth rate of bud take and bud sheet young sprout.
The object of the present invention is achieved like this: after the bondage program of bud grafting is finished, on bud sheet top upwards.0.5-1 centimetre the position, laterally with parallel two cuttves of cutting of stock, reach xylem deeply, two edge of a knife spacings are with 0.5-0.8 centimetre degree of being, knife edge length is that the 1/2-2/3 of incision stock girth is a degree, peels off the bark between two edges of a knife then, expose xylem, when sending forth branches, can remove bondage, remove the above tree crown part of each bud sheet when the winter cuts again when buddering.
Owing to adopt such scheme, can make bud grafting obtain following remarkable result:
(1) owing to peels near the stock skin the bud sheet top off a part, just artificially at the place, lower edge of closing on otch, new " top " has been made in the position that is bud sheet place, thereby form one artificial " apical dominance " at bud sheet place, auxin concentration herein begins to descend, and nutrition is concentrated at this, stock chases after not as good as sprouting new buds herein with treating, this has just given the bud sheet powerful life and vigor just, impels the wound between bud sheet and stock to heal rapidly, and the bud sheet germinates ahead of time.Careful people can find, near the lower edge of fruit tree band girdle wound, even the smooth back that summer bud, hibernaculum all do not have, all can sprout new buds very soon (having started resting bud), and also growing way is surprising, is exactly this reason.
(2) need not injure tree crown after the bud grafting, so that tree crown continues to make nutrition and the preceding nutrition of stock fallen leaves is reclaimed, these nutrition can be by defeated under the residue cortex of each incision of stock, make stock tree body nutritional status unaffected, this has just established abundant nutrition foundation for the later sprouting of bud sheet, growth.
(3) for the still unskilled personnel of graft technology, can avoid the bud sheet not survive, the stock tree crown is inflicted heavy losses in vain;
(4) traditional bud grafting all is to carry out on annotinous branch, but uses this law, the expanded range of bud grafting can be arrived perennial branch and even trunk, and the appearance that it can change head and fruit tree to the branches of tall trees of fruit tree brings great convenience.
(5) its operation is very simple, and effect is highly significant but, and it not only can be brought up to the survival rate of bud grafting more than 95%, and the time shortening that the bud sheet is sprouted is over half, and the growth rate of young sprout is 2-3 a times of ordinary bud grafting method.
Claims (1)
1, a kind of regulating type bud grafting method of tree growth hormone, comprise cutting of scion bud sheet, the cutting of stock, bondage, stripping is cut by bud sheet top above stock skin zone, survive the removal of back bondage and the operations such as amputation of the above tree crown of buddering, it is characterized in that: after the bondage program of bud grafting is finished, 0.5-1 centimetre position makes progress on bud sheet top, laterally with parallel two cuttves of cutting of stock, reach xylem deeply, two edge of a knife spacings are with 0.5-0.8 centimetre degree of being, knife edge length is between the 1/2-2/3 of incision stock girth, peels off the bark between two otch, exposes xylem, treat that the bud length of a film goes out young sprout, promptly remove bondage, when cutting, clip the above tree crown part of each bud sheet again to the winter.
