Description
Technical field
The present invention relates to field of plant cultivation, especially a kind of method of tree peony Root cutting reproduction.
Background technique
Tree peony Paeonia suffruticasa Belong to Paeoniaceae, Paeonia, perennial undershrub is that China is famous
Traditional ornamental flower.Main Cultivation region is in China North China, northwest, Central China, East China and southwestern some areas, in the above area
Cultivation history is long, deep to be liked by the people, elects cry highest in activity in all previous national flowers, is expected to become state, China
Flower.Our people has explored the different reproductive method of tree peony in long-term cultivation, these methods according to appearance elder generation
Sequence is sowing, plant division, grafting respectively afterwards, and there has also been the reports of stem cutting in recent years, but could not apply in production always, mainly
It is that stem cutting rooting rate is extremely low and the seedling time is very long.And traditional tree peony propagation method also has certain limitation, such as sows numerous
The stability of characteristics of Varieties of Peony can not be passed to offspring when growing；The efficiency of division propagation is very low, although propagation by grafiting current year
Survival rate is higher, but grafting needs three Nian Caike with transplant planting, and 3 years storage rates are in most cases in general production
Only 30-40%, even if it has been quite high level that storage rate, which is more than 60%, under good management condition.Base in recent years
Plinth research shows that tree peony some wild ancestors surculose reproductive characteristic under field conditions (factors), but this characteristic is in Planting
It is not observed under the conditions of training.Therefore it is anxious for exploring the Root cutting reproduction how to carry out tree peony using this natural characteristic of tree peony
Problem to be solved.
Summary of the invention
For above situation, for the defect for overcoming the prior art, it is numerous that the purpose of the present invention is just to provide a kind of tree peony root cutting
The method grown can effectively solve the problems, such as that tree peony breeds.
The technical solution of solution is a kind of method of tree peony Root cutting reproduction, comprising the following steps:
(1) adopt root: the plant for choosing field planting 3-6 robust growth (can be in the previous year for adopting root to improve the quality of root
Autumn carry out stump, be affixed by organic fertilizer and reinforce water and fertilizer management, to promote the quality of root system) plane open plant surrounding soil it is exposed on
Half part root system or digging plant are rinsed with water root system, dry 1-2 days, so that root system is become soft, operate in this way
It is not easy to break root, then adopts root with following either method
A, it with sharp sword along root inserted part top 1-3mm, first cuts, is cut through after root inserted part to extroversion inwardly downward
Incision, top connect branch at ") " shape；
B, root is counted from inserted part and stays 15-25cm, be lifted up along branch, split down root from branch, retain one
Part branch；
C, the branch of raw a plurality of adventitious root is cut, then branch is cut into one with gap of the scissors between root and root
A pipe nipple when having two or more roots on one pipe nipple, then the pipe nipple is longitudinally rived between the gap of root；
(2) it trims: retaining root 7-25cm, rest part is cut off, and obtains cuttings；
(3) vernalization: crop field cuttage is carried out again after cuttings is directly carried out crop field cuttage or vernalization；It will first be sheared when vernalization
Cuttings 10-20 branch make a call to a bundle, the cuttings for accomplishing fluently bundle is filled vertically with the fine sand of soil moisture 50-70%, ties and is filled out between tying
Full fine sand, the fine sand of cuttings upper cap thickness 7-8cm cover straw screen or mat, keep soil moisture 50-70%, insert after vernalization 12-17 days
Tip of the spike forms bud not of uniform size, and crop field cuttage is carried out when maximum bud grows to 1-3cm；
(4) cuttage: annual 8-10 month, 22-27 DEG C of soil surface temperature when, carry out cuttage, first irrigate the fields before cuttage,
It levels land, keeps soil moisture 60-70%, first open a bar ditch on the ground when cuttage, keep one side of ditch steep, by cuttings by every
10-15cm mono-, connection branch part is upward, is put on one side along ditch is steep, branch part is flushed with earth's surface when putting, side
It puts side and bankets and fix cuttings, after having put a line, play a ridge along the direction of ditch with soil, make be located at ridge just at the top of cuttings
Centre is finally covered along the direction on ridge with plastic film, makes sure to keep in mind to water；
(5) it is managed after inserting: carrying out first time watering when soil surface temperature is down to 0-5 DEG C, need to check after having poured thin
Film again covers the place leaked out, and spring defrosting backsight soil moisture content of waiting for the coming year decides whether to water, and goes out to the bud in cuttings
After soil, the film above bud is opened, exposes bud, mulching soil is cultivated according to conventional tree peony crop field cultural method.
Operation of the present invention is simple, at low cost, substantially increases the survival rate of tree peony Root cutting reproduction, shortens seedling raise period,
It is the big innovation on tree peony implantation methods, economy and society value is significant.

Present invention applicant in spring in 2010 turning over last year tree peony vacant lot when, it was found that several tree peony roots
Upper end has grown bud and has formd complete peony plant, and most of tree peony roots being scattered have no the formation of bud.By will be above-mentioned
Different tree peony roots are collected, careful observation analysis, it is found that the root for all tops form bud is directly to split from branch
Get off, more or less with the xylem of some branch.By repeated tests, tree peony root cutting of the present invention is obtained
Propagation method.The method that the method for the present invention is currently unique root progress cuttage using tree peony to breed Varieties of Peony, and it is current
The main propagation method of tree peony is compared: compared with grafting, difference is that the root system of breeding target variety is utilized, and is formed
New plant have target variety from root system, do not need to wipe out stock root during subsequent transplanting, growth year shortens；With point
Strain method is compared, and reproductive efficiency is greatly improved.
This method is different on different Varieties of Peony reproductive survival rates, and average survival can achieve 70-90%,
There is higher survival rate compared with grafting, and since cuttage seeding of the invention is own-rooted tree, the seedling time is than grafting
Near a year.3 years ability portables of general grafting, the cuttage seeding 2 years i.e. portables, and its quality cultivated with method of the invention
Grafting higher than 3 years, operation of the present invention is simple, at low cost, substantially increases the survival rate of tree peony Root cutting reproduction, shortens
Seedling raise period, is the big innovation on tree peony implantation methods, and economy and society value is significant.
