Abstract

The invention relates to a rosa microcarpa tree rose twig bark-insertion dual-grafting method. According to the invention, rosa microcarpa is transplanted and is subjected to domestication cultivation; when more than 3 branches grow from the top and the branches are well lignified, a variety of Chinese rose with the best affinity with rosa microcarpa is selected and is grafted onto rosa microcarpa with a bug grafting method; in the summer of the second year after grafting, robust buds germinate from the grafting sites and grow into robust twigs; grafting is carried out when the twigs are still supple and not lignified; the twig is adopted as a rootstock; 1/4-1/3 of the top of the rootstock is cut off; the truncated site of the rootstock is vertically cut from the outer side to the xylem, and the bark layer is opened; the upper part of a scion branch is cut off, and 1-2 buds are remained on the scion branch; the scion branch is cut at the lower end to form a horseshoe-shaped large slope and a small slope; the lower end of the scion is inserted from the opened bark layer of the rootstock, with the large slope facing inwards; the bark layer is torn at the upper end of the rootstock until white color shows slightly; the rootstock and the scion are tightly tied with a plastic strip; the scion can germinate after one week, and can flower one month after grafting. With the grafting method provided by the invention, tree rose has high survival rate and strong and fast growth. Various color varieties can be grafted on one tree.

Description

A kind of tender branch bark inserting double grafting method for shanmuxiang tree type Chinese rose

Technical field

The present invention relates to a kind of Radix Rosae Cymosae dendriform China rose engrafting method is and in particular to a kind of tender branch bark inserting double grafting method for shanmuxiang tree type Chinese rose.Platymiscium graft technology field.

Background technology

Radix Rosae Cymosae is one Wild Rosa multiflora kind of China.Its trunk is thick, and growing way is strengthened, and someone's Radix Rosae Cymosae is stock in recent years, and Chinese rose becomes dendriform China rose for scion grafting, and its trunk is sturdy, and tree crown is big, and growing way is very good.But it has the shortcomings that one fatal it is simply that Radix Rosae Cymosae performance is only good with the affinity of only a few modern rose cultivarses.The modern rose cultivarses counting greatly absolutely are poor with Radix Rosae Cymosae performance affinity.Show as that graft survival rate is low, form very big strumae at grafting after surviving, block the circulation up and down of nutrient, branch growing way is weak, and gradually dead afterwards, make grafting failure.The multiple designs and varieties of grafting simultaneously nor on same one tree, make motley polychrome dendriform China rose.We tested connect with bud and other scion graftings method, the Chinese rose connecing other kinds is remarried on the branch of Radix Rosae Cymosae dendriform China rose, also tested to be remarried on lignified Chinese rose branch connecing other modern rose cultivarses with cortex grafting method, but all do not have successfully.

Content of the invention

It is an object of the invention to overcoming above-mentioned deficiency, provide a kind of engrafting method, make with the incompatible Chinese rose of Radix Rosae Cymosae also can grafting on Radix Rosae Cymosae dendriform China rose, and multiple designs and varieties of a tree grafting can normal vigorous growth for a long time can be made.

The object of the present invention is achieved like this：A kind of tender branch bark inserting double grafting method for shanmuxiang tree type Chinese rose, its way is：

First, Root-stock selection

First Radix Rosae Cymosae transplanting and habituation is cultivated, when its top grows 3 with upper branch and when lignifying is fine, select the kind Chinese rose best with Radix Rosae Cymosae affinity, the method grafting being connect with bud is on Radix Rosae Cymosae, strengthen management after surviving, promote its multiple branch, send out vigorous branches, Chinese rose crown form wipes out all Radix Rosae Cymosae branches after becoming, after grafting, Second Year summer necessarily has strong bud and sends at grafting, and grow up to vigorous branches quickly, when its also non-ordinary water is tender there is no lignifying when carry out grafting, its method is that such branch is done stock, first clip its upper end 1/4～1/2, then indulge standardized knife outside stock truncated position and be deep to xylem, pry open cortex；

2nd, scion is chosen

The Chinese rose branch that degree of lignification is high, bud is full is selected in scion,

3rd, scion branch is stayed 1～2 bud to clip upper end, the big inclined-plane of the shape of a hoof of a long 2～2.5cm is cut in lower end, then cuts a little inclined-plane at the back side on big inclined-plane；

By the big inclined-plane of scion inwardly, scion lower end is inserted at the cortex that stock is pried open, stock upper end is torn cortex and is slightly showed money or valuables one carries unintentionally, finally tight with plastic strip wrapping bundle, section including stock and scion upper end will Bao Yan, in order to avoid moisture loss impact survives, scion after the week is sprouted, and just can bloom within one month after grafting.

4th, grafting operation

High with this method grafting dendriform China rose survival rate, growing way is strengthened, and grows fast.The stock branch that reason is selected is in the organic centre of this tree, and growing way is just prosperous, moisture and nutritional sufficiency, and Endogenous Hormone Contents in Vitro is high.Scion bud is full to save up strength to start out, and degree of lignification higher position is difficult here dehydration withers.Furthermore grafting Chinese rose on Chinese rose, general affinity is all good.Thus make with the incompatible Chinese rose of Radix Rosae Cymosae also can grafting on Radix Rosae Cymosae dendriform China rose.And a tree can the multiple designs and varieties of grafting.

This engrafting method is exactly a kind of innovation.Because although twig connection is in the past existing, be cleft graft.Cortex grafting method also has, but stock selection is lignifying branch rather than twig.With cortex grafting method, on twig, grafting is others not used method, and it is best to be used in double-work effect on Radix Rosae Cymosae dendriform China rose, it solves general modern rose cultivarses and the incompatible problem of Radix Rosae Cymosae, also solves the problems, such as that Radix Rosae Cymosae dendriform China rose is unable to the multiple designs and varieties of grafting.The method is characterized by the scion of cortex grafting is not inserted on common lignifying branch, and it is inserted on twig.It apply the most applicable on special stock one Radix Rosae Cymosae dendriform China rose, can make the extremely incompatible Chinese rose of various Radix Rosae Cymosae connect be formed on colourful spend numerous like brocade polychrome dendriform China rose become showing point of landscape.

Specific embodiment

The present invention relates to a kind of tender branch bark inserting double grafting method for shanmuxiang tree type Chinese rose.Its key step is as follows：

First, grafting time

Suitable grafting time is the 6-8 month, especially with July best.

2nd, Root-stock selection

Choose previous, 2 years grafting survivals Radix Rosae Cymosae dendriform China rose (modern rose cultivarses and Radix Rosae Cymosae affinity are good), when sprouting sturdy sprouting after June at grafting and gradually growing up to the shoot more sturdy than old branch, just can be used for grafting.Branch requires to grow to budding or do not budding.Phloem is thicker than xylem, and marrow water is tender transparent, is about 25-30cm, and it is optimal that such branch does stock.

3rd, scion is chosen

The Chinese rose branch of various pattern flower pattern is chosen in scion, if a tree grafting polychrome is it is desirable to kind growing way will be stronger and consistent or close.Weak tendency kind can not be used, the bud on branch is wanted full and will be sprouted and not yet sprout.

4th, grafting operation

1st, scion branch is stayed one to two full bud, upper end cuts off, lower end is slightly deviateed on bud opposite and cut a shape of a hoof big inclined-plane length 2～2.5cm at the position of bud, the less inclined-plane cutting a 3mm at the back side on big inclined-plane.

2nd, stock branch is cut off at upper end 1/3, down indulge standardized knife from incision outside it and be deep to xylem, pry open cortex from incision.

3rd, by big for scion shape of a hoof inclined-plane inwardly, insert at the cortex that stock is pried open, stock upper end is torn cortex and slightly showed money or valuables one carries unintentionally, finally tight with plastic strip wrapping bundle.Section including stock and scion upper end will Bao Yan.

5th, it is noted that watering it is impossible to fall dry after grafting.Often to apply thin fertilizer a bit with water, for promoting grafting twig growth, by pruning, a certain degree of control can be carried out to non-grafted branch.After one month, grafting twig just can be bloomed, and with other branch syntrophism.

Embodiment：There is the Radix Rosae Cymosae dendriform China rose that red fan (red) grafting of a collection of use single variety Chinese rose becomes.As needed their reconfigurations are become polychrome dendriform China rose.

We in July in the present inventive method, the kind such as powder fan (pink colour), gold medal chapter (yellow), bright cloud (secondary color) in 2-3 newborn grafting of tender branch is selected from every one tree.Budding through the grafting twig that careful management late July has, all bloom to August major part.
