Description

A kind of easy polyanthus propagation method

Technical field

The present invention relates to a kind of easy polyanthus propagation method, belongs to field of plant cultivation.

Background technology

Polyanthus (Narcissus tazettaL.) belong to Amaryllidaceae narcissus platymiscium, perennial herb, leaf are narrow Grow, grow thickly, there is bulb underground, and its spray is more, and the fragrance of flowers is strong, with very high ornamental value.Chinese narcissus（Narcissus tazettaL. var. chinensis Roem. ）It is a mutation of polyanthus, the cultivation in existing more than 1,000 years in China is gone through History, is traditional ornamental flower, is one of Chinese ten big famous flowers.The many juices of Narcissus Tazetta L. Var, it is poisonous, containing lycorine, polyanthus Various alkaloids such as alkali；Surgery is used as analgesics；Bulb is mashed to apply and controls carbuncle.

The existing propagation method of polyanthus has following several at present：1）Side ball breeding method is the upper the most frequently used tradition of production Method.The raw little lepisphere on the outside of big lepisphere is separated by autumn with mother bulb, and little lepisphere is individually planted, and next year produces new ball.Should The bulbec quality of method breeding is good, but reproduction speed is too slow.2）When lateral bud breeding method was castrated using biennial bulb autumn, dig out Both sides axillary bud, be sown on seedbed, next year produces new ball.Due to propagating materialss it is limited, can only be used as other propagation methods Supplement.3）Double scale lining methods are that one, biennial Narcissus Tazetta L. Var is placed in Cold pretreatment at 4～10 DEG C to take out after 4～8 weeks, Excision bulb top, stays the scale of 1～2cm on plateau and disk, then is divided into the tep reel fritter of 2 scales, Ran Houyong The sandstone of water content 6% is mixed with loading plastic bag, and in 20～28 DEG C of lower shading culture, 2～March of Jing can grow clove. But due to bulbec it is too little, second-rate, it is difficult in production promote.4）Tissue culture propagation method was with 4 DEG C of K cryogenic treatment bulbs 1 month Afterwards, it is explant to separate the plateau with scale, scape, bud point etc., using MS culture medium, adds sucrose, BA and 2,4-D, can To induce clove regeneration.The method breeding coefficient is high, and cusp breeding can also deviate from virus, but need complete set of equipments, cost compared with Height, is used for original seed preservation.5）Bulb dice breeding method bulb dice breeding method is that applicant's acquisition national patent in 2007 is awarded One new technique of power.With biennial Narcissus Tazetta L. Var as material, process 4～8 weeks under 4 DEG C of low temperature, at normal temperatures with plateau Bulb is radially slit longitudinally into uniform 8～24 fritter for round dot by center, and plateau and each layer scale are remained with per block, Then the fritter propagating materialss for cutting and the clean sand being filtered dry（Water content 6%）Layering loads in plastic bag, closes bag mouth, In 25 DEG C or so shading 2～March of culture, treat that 1.5 cm of bulbec diameter or so moves into outdoor cropping.Expanding propagation of the rhizome cutting propagation to breeding Environmental requirement is not high, low cost, and breeding coefficient is high, but still needs to set up K cryogenic treatment equipment.

The content of the invention

It is an object of the invention to provide a kind of easy polyanthus propagation method.

For achieving the above object, the present invention is adopted the following technical scheme that：

A kind of easy polyanthus propagation method, comprises the steps：

1）In late October to early November, when polyanthus is in the budding period, choose disease-free, consolidation, push up thick one, Biennial Narcissus Tazetta L. Var peels off bulb outer layer dry film as propagating materialss, rejects withered and silt on plateau, with 0.4% first Aldehyde solution soaking 2～3 hours or 0.1% carbendazim dry in the shade after soaking 12 hours（Disease-free bulb is not required to chemicals treatment）, that is, carry out squama Stem carves wound；

2）It is carved into scale direction from the plateau of bulb base portion with sharp pocket knife, penetrates plateau and go deep into scale 1 ～1.5cm, the bulb after hindering at quarter is sowed in 2 days and is finished；

3）Seeding row spacing 13cm × 28cm, per mu of sowing are sowed in single ball drilling, bar 12～15cm of ditch depth, annual bulb 17000～18000；Biennial bulb sows seeding row spacing 20cm × 38cm, and per mu is sowed 8500～9000；Conventional fertilizer water pipe Reason.Early or mid June, treat that more than 1/3 blade dries up, when bulb initially enters dormancy, select fine day to dig out underground bulb, dry Preserve at shady and cool ventilation.

Step 2）Described in Narcissus Tazetta L. Var girth diameter >=14cm biennial bulb in " * " word carve wound 3 knives, depth reach scale 1.5cm；The bulb of girth diameter ﹤ 14cm carves 2 knives in "+" word, and depth reaches scale 1.2cm.

It is an advantage of the current invention that：It is an efficient, narcissus reproduction technique for high-quality.It is with low cost, easy to operate, The suitability is wide, and breeding coefficient is high, the characteristics of bulb quality is good.In the case where any facilities and equipment are not set up, only need simple Bulb carve injury reason after directly sow, the breeding coefficient of polyanthus different cultivars can just increased between 14～27 times；Very Suitably it is widely popularized in narcissus peasant household.

Specific embodiment

Embodiment 1

Late October, when polyanthus is in the budding period, chooses disease-free, consolidation, push up thick annual Narcissus Tazetta L. Var work For propagating materialss, bulb outer layer dry film is peelled off, reject withered and silt on plateau, it is little with the immersion 2～3 of 0.4% formalin When after dry in the shade, you can carry out bulb carve wound.It is carved into scale direction from the plateau of bulb base portion with sharp pocket knife, penetrates squama Stem disk simultaneously gos deep into scale.Girth diameter carves 2 knives for the bulb of 10cm in "+" word, and depth reaches scale 1.2cm, carves in the bulb 2 days after wound Sowing is finished.Seeding row spacing 13cm × 28cm is sowed in single ball drilling, bar ditch depth 12cm, and per mu is sowed 17000～18000；It is conventional Rich water quality management.Mid-June, treat that more than 1/3 blade dries up, when bulb initially enters dormancy, select fine day to dig out underground bulb, Dry and preserve at shady and cool ventilation.
