Abstract

The invention discloses an azalea selecting and breeding method. A variation branch of anazalea that grows in the hilly mountain area where Taojiang county, Anhuacounty and Hanshou county in Hunan province meet and is in blossom twice a year is selected for grafting and cutting propagation. The method has the advantages that the operation is simple; azalea obtained through selection and breeding maintains the pre-variation special performance, namely the azalea is in blossom twice a year, in April-May and August-September; the anthesis period is more than 3 months; the flowers are big and red; and the flowers give out light delicate fragrance.

Description

The seed selection of a kind of azalea and propagation method

Technical field

The present invention relates to the seed selection of plant variety and breed field, especially relating to seed selection and the propagation method of a kind of azalea.

Background technology

Azalea (formal name used at school: rhododendronsimsiiPlanch.), walk to and for also known as mountain, Randia spinosa, azalea, belong to Cuculidae Genus Rhododendron, evergreen machaka or dungarunga, Xi Banyin, being afraid of high light, is long-day plant.Global azalea about has 900 kinds.China is that azalea distributes maximum countries, and about have more than 530 to plant, azalea is of a great variety, and pattern is gorgeous, flower, Ye Jianmei, and ground plants, potted plant all suitable, is one of Chinese ten great tradition famous flowers.Azalea opens once flower in general 1 year, and flowering stage is generally between 4 ~ June; Seldom open the azalea kind of 2 flowers one year.In order to extend the blooming cycle of azalea and bloom number of times, need to provide seed selection a kind ofly can several times a year to bloom, azalea that blooming cycle is long, and the mating system of this azalea.

CN101080984A discloses seed selection and the propagation method of a kind of azalea " delicate and charming cuckoo ", carries out grafting and cottage propagation by azalea " purple gorgeous " kind bud mutation branch.Spending of this azalea is large, but 1 year only blooms in 4 ~ May, and its blooming cycle is short.

Summary of the invention

The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, provides the seed selection and propagation method that within a kind of 1 year, can open the long azalea of 2 flowers, blooming cycle.

The technical solution adopted for the present invention to solve the technical problems is: the seed selection of a kind of azalea and propagation method, and the azalea that on the Hills selecting growth to have a common boundary in Taojiang County, Hunan Province, Anhua County and Hanshou county, twice flower is opened in a strain for year branch that makes a variation carries out grafting and cottage propagation.

Further, choose azalea that a strain on Hills that growth has a common boundary in Taojiang County, Hunan Province, Anhua County and Hanshou county opens twice flower for 1 year to make a variation branch, one year seedling for the cuckoo cottage propagation stalwartness at common florescence is annually cooked stock, carry out grafting by cleft graft, plant to be grafted grows up and carries out cottage propagation.

Further, be ready in seedbed before cuttage, seedbed width is 80 ~ 100cm, the degree of depth 20 ~ 25cm, spreads perlite 10 ~ 12cm thick, waters permeable, cuttings is cut into 6 ~ 8cm long, extracts unnecessary blade, stay 2 ~ 3, top leaf, be inserted in slotting machine, then water a water, then with plastic film, slotting machine is covered, keep the humidity having 90% in slotting machine, slotting machine ventilated and sprayed water for 1 hour again every day, then covered, after cuttage seeding is taken root, then transplant grow 2 months in seedbed after.

Further, cuttage seeding sprays the potassium dihydrogen phosphate of 0.2% after taking root 10 days, be first transplanted in plastic sack by seedling after seedbed grows 2 months; Treat that bag seedling is transplanted engagement by next year again.

Further, stamen and pruning is plucked during transplanting.

Further, when azalea blooms, its planting environment temperature controls at 20 ~ 28 DEG C, and air humidity is 55 ~ 70%, is placed on area without shade, is conducive to azalea and blooms, and extend blooming cycle.

The seed selection of a kind of azalea of the present invention and the beneficial effect of propagation method: simple to operate, azalea after seed selection breeding keeps the characteristic property before variation, namely azalea opens 2 flowers for 1 year, bloom in 4 ~ May and 8 ~ September respectively, blooming cycle reaches more than 3 months (namely the cycle of azalea from blooming to withering is more than 3 months); Flower is large and red, and distributes light delicate fragrance.

Embodiment

Below in conjunction with embodiment, the invention will be further described.

The seed selection of a kind of azalea of the present invention and propagation method, choose azalea that a strain on Hills that growth has a common boundary in Taojiang County, Hunan Province, Anhua County and Hanshou county opens twice flower for 1 year to make a variation branch, one year seedling for the cuckoo cottage propagation stalwartness at common florescence is annually cooked stock, adopts cleft graft to carry out grafting.

Cottage propagation is carried out the 4 ~ May of next year after plant to be grafted grows up.

Before cuttage, seedbed is ready to, seedbed width is 80 ~ 100cm, the degree of depth 20 ~ 25cm, spread perlite 10 ~ 12cm thick, water permeable, cuttings is cut into 6 ~ 8cm long, extract unnecessary blade, stay 2 ~ 3, top leaf, angular cut is cut into bottom cuttings, be inserted in ready slotting machine, interval 4 ~ 10cm between adjacent cutting, water a water again, then with plastic film, slotting machine is covered, keep the humidity having 90% in slotting machine, the plastic film that slotting machine two ends cover is rolled by every morning 7 ~ 8, after slotting machine is ventilated 1 hour, spray water again, cover again, after cuttage seeding is taken root, transplant after growing 2 months again in seedbed.

Cuttage seeding is generally taken root for 15 ~ 25 days after cuttage, note after taking root adding fertilising, sprayed a foliar application every 1 ~ 2 day, each foliar application sprays the potassium dihydrogen phosphate of 0.2%, offspring to be generated is transplanted grow 2 months in seedbed after, cuttage seeding is first transferred load in ready plastic seeding culturing bag; Treat that bag seedling is transplanted engagement by late March ~ mid-April next year again.

For the strain shape that remains intact and tree vigo(u)r, note plucking flower bud, many buds are extractd, to ensure its nutrition.Be also noted that in addition and note fertilising vegetative period, generally execute the composite fertilizer of 1-2g along basin limit.

When azalea blooms, its planting environment temperature controls at 20 ~ 28 DEG C, and air humidity is 55 ~ 70%, is placed on area without shade, is conducive to azalea and blooms, and extend blooming cycle.

Azalea of the present invention is that seed selection acquisition is carried out in the azalea variation kind strain that on the Hills of having a common boundary in Taojiang County, Hunan Province, Anhua County and Hanshou county growth, twice flower is opened in a strain for a year, and by seed selection in 5 years and breeding, its varietal character is stablized, can keep developing for 2 times throughout the year, be respectively early April to mid-June in 1 year and late August ~ mid-November.
