Abstract

The invention relates to a simple paper-white narcissus propagation method and belongs to the field of plant cultivation. The method is an efficient and superior paper-white narcissus propagation technology, and has the advantages that the operation is easy and convenient, the propagation coefficient is high, cost is low, and seed bulbs are good in quality. Due to the fact that no additional facilities and devices are needed, the method is quite suitable for being widely popularized among narcissus farmers.

Description

A kind of easy polyanthus propagation method

Technical field

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

Background technology

Polyanthus ( narcissus tazettal.) belong to Amaryllidaceae Narcissus plant, perennial root draft, leaf is long and narrow, grow thickly, there is bulb underground, and its spray is many, and the fragrance of flowers is strong, has very high ornamental value.Chinese narcissus ( narcissus tazettaL. var. chinensis Roem.) be the mutation of polyanthus, at existing more than the 1000 year cultivation history of China, being traditional ornamental flower, is one of China's ten large famous flowers.The many juices of Narcissus Tazetta L. Var, poisonous, containing the multiple alkaloid such as lycorine, ungernine; Surgery is used as anodyne; Bulb is mashed deposited carbuncle of controlling and is swollen.

The existing propagation method of current polyanthus has following several: 1) ball breeding method in side produces upper the most frequently used conventional method.Raw little lepisphere outside large lepisphere is separated with mother bulb by autumn, and little lepisphere is planted separately, and next year produces new ball.The bulbec quality of this method breeding is good, but reproduction speed is too slow. 2) lateral bud breeding method is that when utilizing biennial kind of ball to castrate autumn, the both sides axillalry bud dug out, is sown on seedbed, produces new ball next year.Because propagating materials is limited, can only supplementing as other propagation method. 3)two scale lining method be by one, biennial Narcissus Tazetta L. Var be placed in 4 ~ 10 DEG C at Cold pretreatment take out after 4 ~ 8 weeks, excision bulb top, stay the scale of plateau and the upper 1 ~ 2cm of dish, be divided into the tep reel fritter of 2 scales again, then loading plastic sack is mixed with it with the sandstone of water content 6%, cultivate the lower shading of 20 ~ 28 DEG C, can clove be grown through 2 ~ March.But because bulbec is too little, second-rate, be difficult to promote in production.4) tissue culture propagation method is with 4 DEG C of low temperature treatment kind balls after 1 month, and the plateau, scape, bud point etc. of separating belt scale are explant, and use MS medium, add sucrose, BA and 2,4-D, can induce clove to regenerate.This method reproduction coefficient is high, and cusp breeding can also deviate from virus, but needs complete set of equipments, and cost is higher, is used for original seed and preserves.5) bulb dice breeding method bulb dice breeding method is the new technology that applicant obtains national patent mandate for 2007.With biennial Narcissus Tazetta L. Var for material, 4 ~ 8 weeks are processed under 4 DEG C of low temperature, at normal temperatures with plateau center for bulb is longitudinally cut into uniform 8 ~ 24 fritters by round dot radially, every block all remains with plateau and each layer scale, then the fritter propagating materials cut and clean sand (water content 6%) layering be filtered dry are loaded in plastic sack, close sack, about 25 DEG C shadings cultivate for 2 ~ March, treat that bulbec diameter 1.5 about cm moves into outdoor cropping.The numerous environmental requirement of the expansion of rhizome cutting propagation to breeding is not high, and cost is low, and reproduction coefficient is high, but still need set up low temperature treatment equipment.

Summary of the invention

The object of the present invention is to provide a kind of easy polyanthus propagation method.

For achieving the above object, the present invention adopts following technical scheme:

an easy polyanthus propagation method, comprises the steps:

1) in late October to early November, when polyanthus is in the budding period, choose anosis, consolidation, top thick one, biennial Narcissus Tazetta L. Var is as propagating materials, peel off the outer dry film of bulb, reject withered and silt on plateau, dry in the shade (anosis kind of ball does not need chemicals treatment) after soaking 12 hours with 0.4% formalin immersion 2 ~ 3 hours or 0.1% carbendazim, namely carry out bulb and carve wound;

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

3) single ball drilling, bar ditch depth 12 ~ 15cm, annual bulb sowing seeding row spacing 13cm × 28cm, sows 17000 ~ 18000 for every mu; Biennial bulb sowing seeding row spacing 20cm × 38cm, sows 8500 ~ 9000 for every mu; Conventional fertilizer water management.Early or mid June, treat that the blade of more than 1/3 dries up, when bulb starts to enter dormancy, select fine day to dig out underground bulb, preserve in shady and cool ventilation place after drying.

step 2) described in narcissusthe biennial bulb of bulb girth diameter>=14cm carves wound 3 cutter in " * " word, and the degree of depth reaches scale 1.5cm; The bulb of girth diameter ﹤ 14cm carves 2 cuttves in "+" word, and the degree of depth reaches scale 1.2cm.

The invention has the advantages that: it is the narcissus propagation technique of efficient a, high-quality.Have cost low, easy and simple to handle, applicability is wide, and reproduction coefficient is high, plants the measured feature of ball matter.When not setting up any facilities and equipment, only needing simple kind after injury reason carved by ball directly to sow, the reproduction coefficient of polyanthus different cultivars just can be made to increase between 14 ~ 27 times; Very suitablely extensively to promote in narcissus peasant household.
