Description
Technical field
The invention belongs to the grafting method of trees in the gardening, particularly, belong to the method for grafting camellia on giant tea tree.
Technical background
Camellia (Camellia japonica) is the Theaceae arbor, blooms in the Winter-Spring, spends large-scalely, and common is large red.Kind is a lot of in the gardening, and existing single-lobe has polyphyll again, and pattern is red to differ in vain.The not only tree-like grace of giant tea tree, evergreen, the full branch of full-blown flowers of the four seasons, and can absorb airborne sulphide, have the function that purifies air.Tea tree is experienced all sorts of cultivation, has become one of famous ornamental plants of China.By the kind heap sort of camellia plant, can be divided into camellia group, ancient tea group and oil tea group.The oil tea aboundresources of China's spontaneous growth, the emphasis vitellarium is the Yunnan-Guizhou Plateau, is many with Guizhou especially.Tea oil tree also is a kind of oil crop, and its oil tea really is one of edible oil materials resource.Tea oil tree grows into after death, and no longer the result is often cut down by people, so that upgrade.The giant tea tree of this tree-like grace has very high value of viewing and admiring with greening environment, so destroys different from unfortunately.Up to now, people are very few for the utilization research of the big tree of fruitless camellia.
Traditional camellia grafting method is an inarching method, the typical case that Chinese patent application part CN200510023485.7 number " camellia tree quick-forming engrafting technique " is exactly this method, though this method can the grafting camellia, but need utilize potted plant little tree as scion, therefore can only carry out on a small quantity, and the management trouble, the grafting success rate of camellia is not high.
Summary of the invention
The object of the present invention is to provide a kind of grafting method that utilizes the big tree camellia of the many kinds of tree that the big tree of century-old oil tea carries out; its cultivation is become the big tree camellia of the many kinds with good ornamental value; protecting the tea oil tree resource of China effectively, and make and utilize fruitless tea oil tree to beautify the environment to become possibility.
To achieve these goals, the inventor is through reaching 10 years of researches and practice, through thousands of time failure and successes, find out a plurality of and even dozens of kind of the complete big tree grafting of a strain oil tea of a cover finally and can survive, leave the gardening method of multiple large-scale camellia.
The grafting method of the big tree camellia of the many kinds of tree that the inventor provides comprises:
(1) select stock and scion,
The big tree of oil tea of choosing tree-walk 10~70cm is as stock, and the big tree of oil tea can be original growth, also can be transplanting survival; According to the design of carrying out in advance, the camellia kind of choosing healthy growth is as scion, wherein with the camellia of famous and precious kind for well, the flower footpath that scion has is big, can reach 22cm, the flower that has is directly littler, only 12cm.
(2) preparation medicament
Heal as early as possible for the wound tissue that makes stock and scion, guarantee that scion survives, and reduce the loss of plant moisture, must impose medicament to wound tissue during grafting, so must prepare medicament before the grafting.Used medicament can adopt one of following 3 kinds of liquid medicine:
1. adopt indolebutyric acid (IBA), methyl (NAA), 3 kinds of chemical substances that can promote plant establishment of heteroauxin (IAA), with the alcohol dissolving, convert the weak solution that water 600~1000ml obtains with every 1g then earlier;
2. convert the solution that water 100ml makes with 1 of somedon, 2 in dimension C tablet;
3. the juice of squeezing out with leaf and the bar of white common calla.
(3) before the grafting to stock and the scion sterilization that carries out disinfection
Giant tea tree as stock will spray with disinfectant commonly used before grafting, the sterilization that carries out disinfection, the weeds around the big tree of removing simultaneously; Camellia as scion also will spray the liquid medicine disinfection, as long as but be sprayed on its branch.
(4) cut a grafting
Around stock, put up falsework earlier, its highly through treetop; Stock is cut away a part of branch according to design, and correspondingly clip is as the branch of the camellia of scion, and the branch diameter that branch diameter that cuts and stock cut away is close; Then the stock otch is cut into wedge shape, the otch of scion also is whittled into corresponding wedge shape; Immediately medicament is coated with completely all cut, otch, clip, then the branch cut alignment of scion is inserted the otch of stock branch, form grafting; When inserting, must aim at, accomplish that skin is to skin; If both thicknesses are not too consistent, must aim at one side, also want skin to skin; Be cut into plastic film then little grafting tied up tightly, prevent into water.
The binding method that plastics are little is: earlier twine twice in the joint portion of stock and scion, it 2/3 is wrapped in the joint portion, and 1/3 surpasses the mouth of cutting of scion; Continue to twine twice then, 1/3 encircling that will exceed makes its strict sealing; The otch that later twines stock seals again.
(5) safeguard measure after the grafting
Hang an air-locked plastic sack in stock and scion place, wherein load onto an amount of water, tighten sealing then, guarantee that scion grows in the high humility of 25~40 ℃ high temperature and 80%~90%; Add black plastic bag sunshade 30 days in grafting; After the grafting of full tree is finished, whole strain tree is put shade net.
(6) administrative skill after the grafting
After the grafting complete stool is sprayed a potassium dihydrogen phosphate, have additional nutrients; If red, white mould bacterium appears in the stock plant, or when blade face, trunk damaged by vermin, should spray lime sulfur one time.
Plant to grafting is often observed, and finds to hang over when water has evaporated in the small plastic bag of grafting place, injects clear water with injection needle and is replenished.
When finding that scion begins the young sprout of growing, and when sending 2~3 leaves, should in time cancel plastic sack and bundling bag; When scion young sprout lignification, remove sky shade.
(7) administrative skill of grafting after 3 months
After the grafting 3 months, should in time mend the scion of death and to connect, strengthen the water of stock, fertile management simultaneously, keep the skin wet and nutrient.After young sprout is sent in scion, spray water every day sooner or later one time, potassium dihydrogen phosphate of spray in per 20 days, the nutrient of increase giant tea tree and scion; Note rejecting the twig that giant tea tree self sends; As find damage by disease and insect, should in time spray insecticide.
It must be noted that,, except implementing above-mentioned technology,, should carry out an insect-pest processing in per 3 months limb and the root of big tree for the giant tea tree of transplanting survival, and disinfection; Per 2 months to the tree root fertilising once, sprayed potassium dihydrogen phosphate once for grafting and limb in per 20 days; The situation of pruning in the time of also will transplanting according to giant tea tree when grafting is carried out the grafting of shaping formula, makes tree-like attractive in appearance; For the branch grafting, the grafting of carrying out another after one again should connect, in order to avoid the pruning wound causes the plant dehydration too much.
Use the grafting method of the big tree camellia of the many kinds of tree provided by the invention, can change into the big tree of camellia that to leave the famous and precious kind in dozens of China and foreign countries to a strain giant tea tree, they have kept gene separately separately, therefore, the camellia pattern of leaving, flower shape and Hua Jing have nothing in common with each other, and reach the effect of nonvolatil nondiscolouring, indeformable, not mutation.To the grafting of original place giant tea tree, can recover former plant type in 1~2 year; To the grafting of transplanting survival giant tea tree, can recover former plant type in 3~5 years.The present invention is applicable to the occasion of Big Flos Camelliae Japonicae tree as the ornamental trees and shrubs of beautifying the environment, is the extremely strong horticulture technique of a kind of practicality.
