Abstract
The invention discloses a method for improving the graft survival rate of a holly, which comprises the following steps: from the last ten-day of February to the middle ten-day of March and 3 to 5 daysbefore grafting, irrigating a grafting nursery with water once thoroughly; scissoring a twig of a variety to be grafted, which grows robustly with good buds and has a thickness of between 1 and 2 centimeters as a scion, using a grafting knife to cut obliquely once at a 1-centimeter part on the back of a scion bud to cut off 1/3 of a xylem and ensure that the inclined plane is about 2 centimetersin length, then cutting a small inclined plane on the back side of the inclined plane to cut off certain xylem slightly and ensure that the bevel of between 0.5 and 0.8 centimeter in length, and scissoring off the scion at the position of 1 to 2 centimeters above the bud; planting a Chinese holly selectively (without considering the stem height and the thickness), using a lateral branch twig of which the thickness is between 1 and 2 centimeters as a rootstock, using a pair of lopping shears to shear at the position of 5 to 6 centimeters above a bifurcation, selecting a smooth position around the rootstock bark, and cutting vertically downwards for about 2 centimeters at the smooth place with a slight xylem; inserting the scion into a cut of the rootstock so that cambiums on two sides of the long inclined plane of the scion are aligned with and abutted against the cambiums on two sides of the rootstock, and if the scion is thin, the scion is ensured to be aligned with the cambiums on one side of the rootstock; fastening and sealing the cut by a plastic strip at an inserting opening from top to bottom; watering the interface with a watering pot, and sleeving a plastic bag on the cutso as to seal the cut and preserve moisture; building a shading net for sun-shading and temperature reduction at a position 2 meters above the nursery; and removing the plastic bag sleeved outside.
Description
Technical field
The invention belongs to trees and breed the field, relate to a kind of method that improves graft survival rate of holly.
Background technology
The Ilex seed because plant skin depth, embryonic development is incomplete, so seeding and seedling raising germination rate not only very low (0～50%) but also germinating time are long, 2 years even the longer time could germinate, and the ten minutes of growing are slow, so seed seedling-raising is very difficult.At present, Chinese ilex commodity seedling-wood breeding mostly is to adopt the Chinese holly seedlings of easily breeding to do stock to carry out propagation by grafiting, but owing to be subjected to the influence of many factors, graft survival rate is often very low, generally 30～50%.Breed difficulty and not only the nursery stock development of Ilex has been formed certain restriction, and caused two kinds of drawbacks, the one, repeatedly mend grafting, the cultivation period of commercial seedling is elongated, and seedling cost is significantly improved; The 2nd, the best period of having postponed the commercial seedling listing causes that the nursery stock selling price is on the low side, economic benefit is not high.
Summary of the invention
Technical problem to be solved by this invention provides a kind of method that improves graft survival rate of holly, to overcome the deficiency that cultivation period is long, seedling cost is high of the commercial seedling that traditional grafting pattern causes.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:
A kind of method that improves graft survival rate of holly comprises the steps:
(1) late Febuary～mid-March, before grafting 3～5 days, treats that the grafting nursery irritates once permeable.
(2) clip robust growth, the bud grafting kind branch for the treatment of good, rugosity 1～2cm are done scion, with grafting knife 1cm place, the back side of bud under scion cutter of splaying, ream 1/3rd xylem, about the long 2cm in inclined-plane, cut a little inclined-plane again at the back side on inclined-plane, some xylems of pruning a little, the long 0.5～0.8cm of bevel, 1～2cm cuts scion the place above bud.
(3) selectively plant Chinese holly, the branch of side shoot rugosity 1～2cm is done stock, and 5～6cm place above the distance bifurcated shears with shrub and hedge trimmer, selects anvil skin smooth place on every side, and slightly xylem is vertically downward about vertical cut 2cm.
(4) scion is inserted in the otch of stock, make the cambium on both sides, long inclined-plane of scion and the cambium on stock both sides aim at, be close to,, must guarantee that scion aims at the cambium on stock one side if scion is thin.With plastic strip tighten from top to bottom at spigot, cut sealing.Sprinkle water at interface with watering can, preserve moisture with plastic sack bagging tying in grafting part again.
(5) on grafting ground, take cool canopy about 2 meters high, with sunshade net sunshading and temperature reducing.
(6) 30～40 days removal plastic bag sleeved outside after the grafting.
In the step (4), described plastic strip thickness is 0.05～0.07mm, the wide 0.8～1.2cm of being.
In the step (4), described plastic sack size is 30 * 45cm.
In the step (4), described plastic sack color is a black.
In the step (5), described sunshade net shading rate is 75%.
Beneficial effect: the method for raising graft survival rate of holly of the present invention, make the graft survival rate of Chinese ilex bring up to 95.3%, shorten the field of Chinese ilex commercial seedling widely and cultivated the time, make seedling cost significantly reduce (having reduced benefit grafting number of times), can make commercial seedling go out the garden in advance again, occupy the dear market of nursery stock.
Embodiment:
According to following embodiment, the present invention may be better understood.Yet, those skilled in the art will readily understand that embodiment only is used to illustrate the present invention, and should also can not limit the present invention described in detail in claims.
Embodiment 1:
In late Febuary, 2005～mid-March, in Nanjing, Jiangsu Province, select the nursery (stock ground and scion ground) of grafting, before grafting, irritated once permeable in 3～5 days; Scion is the Ilex seeds from the U.S. and Holland's introduction, as: 10 kinds such as the yellow line Chinese ilex that comes into leaves, red plover Chinese holly, Lawson's gold heart Chinese ilex, the golden-rimmed Chinese ilex of golden Supreme Being, flower thorn Ilex aquifolium, clip robust growth, bud branch good, rugosity 1～2cm are done scion, with grafting knife 1cm place, the back side of bud under scion cutter of splaying, ream 1/3rd xylem, about the long 2cm in inclined-plane, cut a little inclined-plane again at the back side on inclined-plane, some xylems of pruning a little, long 0.5～the 0.8cm of bevel, 1～2cm cuts scion the place above bud; Selectively plant Chinese holly, the branch of side shoot rugosity 1～2cm is done stock, and 5～6cm place above the distance bifurcated shears with shrub and hedge trimmer, selects anvil skin smooth place on every side, and slightly xylem is vertically downward about vertical cut 2cm; Scion is inserted in the otch of stock, make the cambium on both sides, long inclined-plane of scion and the cambium on stock both sides aim at, be close to,, must guarantee that scion aims at the cambium on stock one side if scion is thin; With plastic strip tighten from top to bottom at spigot, cut sealing, sprinkle water at interface with watering can then, preserve moisture with black plastic bag bagging tying again; On grafting ground, take the cool canopy sunshading and temperature reducing about 2 meters high then; 30～40 days removal plastic bag sleeved outside after the grafting.This method is total to 38497 grafting scion, survives 36688, survival rate 95.3%.
