Description

A kind of Chinese herbaceous peony propagation method
Technical field
The present invention relates to a kind of Chinese herbaceous peony expanding propagation methods, belong to flowers breeding field technical field.
Background technology
Chinese herbaceous peony is the ornamental and medical flower of Chinese tradition, originates in China, is Paeoniaceae Paeonia herbaceos perennial, There is long cultivation history.Chinese herbaceous peony《Book of Songs Zheng's wind》In just have the verse of " Wei Shi and female, she it mutually filters, give with Chinese herbaceous peony ". Because being presented to when men and women feels reluctant to part, therefore the ancient Chinese people are using Chinese herbaceous peony as will be from grass.Tang and Song Dynasty time, Yangzhou cultivation are most contained.Soviet Union Eastern slope Zeng Yun:" Yangzhou Chinese herbaceous peony is the first on earth ".Chinese herbaceous peony flower-shape comfort it is charming, it is splendid, have that " tree peony is flower king, and Chinese herbaceous peony is an ancient times The saying of flower phase ".Since Ming and Qing, the cultivation of the ground such as Shandong Caozhou (modern Heze), Beijing Fengtai is more, at present in the Qinling Mountains, Dabie Mountain Etc. ground still have wild resource, and have cultivation throughout the country.
Chinese herbaceous peony due to tool color, perfume (or spice), rhythm three U.S., the successive dynasties, scholar extraordinarily extolled, and left largely immensely popular poem. Korea Spro Tang Dynasty more has a first four-line poem with seven characters to a line, and " great state mad fragrant former times is not met, and red light glitters green listing cage;Feel come it is solely terrified to feelings, in asgard which Weight ", with the abundant imagination, introduces people among bright and glittering, too beautiful to be absorbed all at once dreamland.Now, Heze Prefecture's not only Chinese herbaceous peony Medicine is famous, and cultivation is also many extensively for Chinese herbaceous peony.Whenever Chinese herbaceous peony, Chinese herbaceous peony bloom the time in succession, there is crowded, in an endless stream not Absolutely.Chinese herbaceous peony is also described as " Hua Xian " by people, and is listed in one of ten big famous flowers, and be otherwise known as " flora in May ", because just making from ancient times For the flower of love, by representative flowers that honor is the seventh evening of the seventh moon in lunarcalendar.
The traditional propagation method of Chinese herbaceous peony includes seeding method and offshoot.Wherein offshoot because can ensure breediness and It is widely adopted.Seeding method is only used for using during breeding of new varieties, and the characters of progenies generated due to sowing is it occur frequently that detach, no The merit of original kind can be kept, in fact, seeding method is generally not used for the breeding of ornamental peonies kind.
Offshoot is the most common propagation method of Chinese herbaceous peony, and the nursery stock production in Chinese herbaceous peony producing region is bred substantially using this method.Plant division It carries out within general every 2 years or 3 years primary.Fleshy root has been dug during plant division, has reduced to the greatest extent and hinders root, after having dug, removal place soil is pruned old Hard rotten place, with hand or scraper along being split at natural gap point.In the case that every 3 years carry out once, general every plant can divide 4 left sides Right sub- strain, per sub- about 2-3 bud of strain band;If fruit bud is very little, restoration ecosystem may be too slow, retains 1 to 2 per height strain during plant division A root tuber, other root tubers will remove.Offshoot has the following advantages that:Axillary seedling can next year bloom;Plant division is easy to operation, Saving of labor is managed, conducive to extensive use;It can keep the merit of original kind.But offshoot there are breeding coefficient it is low lack Point, triennial maternal plant can only divide the sub- strain of 2-4 or so, it is difficult to adapt to and meet the big production of modernization and constantly rapidly increase The needs of long domestic and international flowers market.
It has been reported that at present and Chinese herbaceous peony is bred using cuttage and the planting of layer, then both methods only theoretically carries And be actually always not carried out, because cuttage may be too harsh to ambient temperature and humidity and water and fertilizer management requirement Or other reason, the report for seedling of also being taken root not yet by cuttage at present.
To sum up, the breeding coefficient of Chinese herbaceous peony is very low at present, the breeding of Chinese herbaceous peony is seriously affected and has expanded numerous.Therefore, mesh Before be highly desirable to a kind of Chinese herbaceous peony propagation method with high breeding coefficient.
Invention content
In order to solve the problems, such as that Chinese herbaceous peony breeding coefficient is low, the present invention provides the Chinese herbaceous peony breeding sides with high breeding coefficient Method, so as to overcome the problem.Concrete scheme is as follows.
1st, a kind of Chinese herbaceous peony propagation method, which is characterized in that described method includes following steps:
(1) root tuber of Chinese herbaceous peony is obtained, the root tuber has at least one bud eye;
(2) root tuber is subjected to sand storage until bud eye germinates;

Specific embodiment
As described above, the present invention provides a kind of Chinese herbaceous peony propagation method, described method includes following steps:(1) Chinese herbaceous peony is obtained The root tuber of medicine, the root tuber have at least one bud eye;(2) root tuber is subjected to sand storage until bud eye germinates;It (3) will budding Root tuber take out and transplant.
In some preferred embodiments, the length of the root tuber is 4 to 15cm, preferably 6 to 10cm.If root segment It is too short, it may result in bud ratio reduction.If long, breeding coefficient may be reduced.
In some preferred embodiments, during sand storage by the root tuber with respect to the horizontal plane into the angle less than 15 degree It puts, preferably basic horizontal or flatly puts.The inventors discovered that being greater than 45 degree, possibly root segment can not be made in sand It sprouts during hiding, this is very unexpected, and concrete reason is up for further studying.It if it should be noted that will Angle is set greater than 15 degree and less than 45 degree, perhaps can be certain bud ratio, due to season, the present inventor It does not attempt also, and plan further to be tested next year at present.
In some preferred embodiments, the humidity of sand storage is maintained at more than 60%, preferably 70% to 95% model In enclosing, temperature is maintained in the range of 16 DEG C to 26 DEG C;The present inventor passes through monitoring temperature and humidity is found, relative humidity and temperature Degree can make Peony Root section germinate well in the range.
The present invention does not have particular/special requirement to sand storage depth, as long as above-mentioned temperature and relative humidity can be kept, still In some preferred embodiments, sand storage is 4cm to 10cm, can so be easier to realize the humidity and temperature condition.
The root of Chinese herbaceous peony is made of three parts, i.e. rootstock, root tuber and fibrous root.Rootstock is located at the topmost of root, is that bud life Position;Root tuber is born below the rootstock, and meat is sturdy, in spindle-type (referring to Fig. 1) or strip (referring to Fig. 2), thick 0.8 to 4.0 centimetres are differed, being rich in nutrition, are not sprouted directly;Fibrous root is born from root tuber, is the major organs for absorbing nutrient and moisture, can To be gradually evolved into root tuber.In some preferred embodiments, the Chinese herbaceous peony be root tuber spindle-type kind, such as selected from by ' the coral light setting sun ' kind (Paeonia Hybrid ' Coral Sunset ' or ' angel's cheek ' kind (Paeonia Lactiflora ' Angel Cheeks ') composition group root tuber spindle-type kind.If using the Chinese herbaceous peony of other root tuber types Medicine possibly can not make stem section sprout.In some preferred embodiments, the diameter of root segment is preferably not less than 1.5cm, example Such as it is 1.5cm to 5cm.
In some preferred embodiments, wound or use are smeared using Cosan before sand storage after the root tuber obtains Then the potassium permanganate solution dipping wound of 0.5 mass % to 2.0 mass % dries in the shade 2 to 3 days.It is of course also possible to without It dries in the shade and directly carries out sand storage.In addition, other common sterilization methods can also use, for example, plant ash or carbendazim it is water-soluble Liquid.
In some preferred embodiments, the root tuber that the obtains when root tuber is from conventional plant division.Can so it facilitate Ground handles the sub- strain that traditional plant division method obtains together.
The plant division of Chinese herbaceous peony, theoretically, from more hibernaculum enrich when to soil it is freeze-up before can carry out.But in due course plant division is planted It plants, ground temperature is still high, is conducive to the healing of root system wound, and can sprout new root, the cold-resistant and drought-enduring ability of enhancing, for sprouting for next year Bud growth lays the foundation.Can not too early plant division, to avoid the autumn find as influencing the growth and development in next year;Also it is too late point unsuitable Strain, ground temperature has been unable to meet the needs of Chinese herbaceous peony root of hair at that time, so that next year new strain undergrowth;If being transplanted late to spring plant division, Bud, which is sprouted, to be unearthed, and because spring temperature is gradually high, air themperature is small, transpiration rate is big, and root system is injured after plant division, it is impossible to normal absorption moisture And nutrient, cause stubble growth very weak or even dead.Therefore, the conventional plant division time generally all arrives when more hibernaculum is enriched Before soil is freeze-up.For example, the area between 30 degree to 40 degree of north latitude, it, can be in September to October such as Heze City, Shandong Province or Beijing It carries out, is preferably carried out in late September to early October.Then, in some preferred embodiments, the root tuber obtain when Between to carry out conventional plant division to obtain the time of sub- strain.Certainly, root tuber is obtained and using at same method in other times It manages also possible.
In the case of being obtained when the root segment is in conventional plant division, the method can also include obtain conventional plant division The step of sub- strain breeding, it is preferred that the sub- strain has the root tuber of 2 to 4 buds and 1 to 3 length for 6cm to 15cm.Together Sample, this is advantageous in that easily root segment can be handled while by sub- strain division propagation.Plant division The sub- strain of acquisition can directly carry out general planting;The root tuber of acquisition then can by or without after sterilizing carry out sand storage at Reason.In some preferred embodiments, the sub- strain is dried in the shade 2 to 3 days after plant division, then carries out general planting.
In some preferred embodiments, the root tuber (or root segment) obtains from the plant division plant of 2 to 6 years, excellent Choosing is obtained from the plant of 3 to 5 years.If plant age is too small, satisfactory root segment may be very little, so as to realize height Breeding coefficient.If plant age is excessive, the increase of the quantity and length of root tuber is limited with the growth at age, it is thus possible to make Numerous time efficiency, which must be expanded, to be reduced.
The present invention will be hereafter further described by the form of embodiment, but protection scope of the present invention is not It is limited to these embodiments.
