Abstract

The invention discloses a novel method for grafting peony, relates to a method for grafting flowers and plants, and belongs to the field of agricultural technologies. The novel method for grafting peony is characterized by comprising the following steps: selecting sprout tillers branches (soil sprouts) of robust plants as scion woods and cutting the scion woods into coins which are 5-10 long and have 1-2 full sprouts; symmetrically shearing two sides of parts which are 3cm far away from the lower ends of the scions for two times by using scissors, forming triangle shapes, inserting the scions along with sheared openings and tightening the scions by using thin hemp ropes. The novel method for grafting peony has the beneficial effects that the method is simple to operate, practical and effective; only one tool which is scissor is used in a shearing method, so that the grafting speed is improved; large contact areas between stocks and scions which are treated by the scissors are achieved; a high survival rate is achieved; the breeding efficiency is improved; and the novel method for grafting peony is a brand new grafting concept and technology.

Description

A kind of new method of tree peony grafting

?

Technical field

the grafting method that the present invention relates to a kind of flowers, belongs to agricultural technology field, specifically a kind of new method of tree peony grafting.

Background technology

Tree peony is traditional famous flower of China, is described as the king in spending.Since Zi Sui Tang, the several years become national flower in history.According to textual criticism, China's Peony growing history has bimillennium; Its flower is very large, elegant and poised, and the symbol as civilized, harmonious, flourishing, rich and powerful, has wide cultural products market demand at home and abroad.Tree peony not only has high ornamental value, also has considerable medical value.The traditional modes of reproduction of tree peony has seminal propagation, division propagation, propagation by layering and propagation by grafiting etc.

People find in woods after the mutual frictionally damage of tree branches very early, press close to each other and the natural graft phenomenon that links up, and ancient Chinese is called " wooden couple very much in love ".Grafting is exactly to be subject to the inspiration of this natural phenomena and a kind of production technology of creating.Grafting is one of the breeding plant method of manually seeking, and, branch or the bud of a Plants, grafting, on the stem or root of another kind of plant, makes two parts that are connected together grow up to a complete plant.During grafting, should make the formation layer of scion and stock combine closely, to guarantee that scion survives, the branch or the bud that connect, be called scion, the plant corpus being connect, is called stock or platform wood, during scion, generally select the seedling of 2～4 buds of tool, after grafting, become top or the top of plant corpus; After stock grafting, become the root system part of plant corpus.

In agricultural production, grafting is constantly being used as a kind of asexual reproduction method.By the closer plant of affiliation is carried out to grafting, can keep parent's good characteristic, result, strengthens resistance and adaptability ahead of time, improves output, improves quality.

Generally speaking, traditional tree peony grafting and the method for facilitating adopt grafting knife by stock and scion as required, are whittled into the shape of agreeing with mutually at its desired area, and scion is embedded in stock otch, tightly wrap up, and then with transparent membrane, seal whole grafting part.The contact area that this grafting method forms scion formation layer and stock is little, and less, survival rate is low for healing point, and by underground plantation, seedling is slow, the cycle is long.And because traditional grafting method is put into use instrument for grafting knife, in practical operation, cutting of scion is easier to hinder hand, therefore, need a kind of simple to operate, practical grafting method.

Summary of the invention

The object of the present invention is to provide a kind of new method of tree peony grafting, overcome traditional tree peony grafting and facilitate the defect of method, solve that the tree peony breeding cycle is long, cost is high, graft survival rate is low and easy aging, the problem of easily hindering hand, the scientific and technological level and the production efficiency that improve Peony growing breeding, better meet the demand of people to flowers.

For achieving the above object, the new method of a kind of tree peony grafting of the present invention, is characterized in that:

One, the time: 8～by the end of October; Be preferably mid-September;

Two, material is selected: select diameter to do stock at 2～4 years raw tree peony seedlings or the Chinese herbaceous peony seedling of 1.2～1.5cm; The processing of stock is also divided into: stock is taken out from soil to post processing;

stock is directly processed in soil; Stock top is cut flat, then move down about 1cm place and tiltedly cut a cutter (noting not cutting); Be preferably Paeonia papaveracea;

Three, grafting method: grafting method is divided into:

root connects;

connect; Select the descendant (native bud) on healthy and strong plant to do fringe bar, be cut into long 5～10cm and with the scion of 1～2 full bud; With scissors, from scion lower end 3cm bilateral symmetry, cut two cuttves, form triangular shape, the stock of scion insert handling being crossed along the edge of a knife, fine cordage tighten;

Four, the management after grafting: Routine Management.

The described time elects for 8～mid-October as, and at this moment temperature is suitable, and peony scion is lignification, and rootstock seedling also survives, and graft survival rate can be up to 90%.

Described connects as stock being taken out from soil to post processing, inserts scion, fine cordage tighten; Connect stock directly processed in soil, insert scion, fine cordage tighten.

Described montage method is only with the same instrument of scissors, and traditional tree peony grafting method all must be used grafting knife, the different instrument of scissors, has significantly improved like this grafting speed.

After described grafting method grafting, the contact-making surface of stock and scion is large, and scion insertion stock is difficult for mobile dislocation, and survival rate is improved, convenient, time saving and energy saving, minimizing cost.

Described fine cordage tighten has replaced traditional grafting to use plastic film bondage, after film bondage, need to after grafting grows to a period of time, plastic film be removed, this process has reduced the pollution of plastics to environment, and because fine cordage can be degraded, and scion and stock are difficult for loosening.

The new method of a kind of tree peony grafting of the present invention, its beneficial effect is: easy and simple to handle, effectively actual, montage method, only with the same instrument of scissors, has improved grafting speed; Stock, the scion contact-making surface through scissors, processed are large, and survival rate is high; Montage method scissors cut face of the present invention is large and dark, and it is firm that scion insertion is stablized, and survival rate is generally all more than 90%; Fast growth after grafting, has improved reproductive efficiency, has easily survived, simultaneously can connect, again can root knot, be a kind of brand-new grafting theory and technology.
