Description
Technical field
The present invention relates to technical field of flower cultivation, and in particular to a kind of Ranunculus asiaticus hybrid seed quality of improving has efficacious prescriptions
Method.
Background technique
Ranunculus asiaticus (Ranunculusasiaticus (L.) Lepech.) also known as celery flower, Lu Lianhua, are Ranunculaceae, flower
Ranunculus perennial herb flowers.Pattern is abundant, mostly polyphyll or half polyphyll, and flower pattern is but smaller like peony, and flower diameter is general
For 8-10cm, leaf therefore is commonly referred to as celery flower like the leaf of celery.Originate in W. Asia and the Asia west and south.English in 1596
Compatriots are introduced into row artificial cultivation, very common in gardens and cut-flower.There are cultivation, Holland, Britain, France, beauty in present various countries more
The cultivation such as state, Japan is more, and cultivates many cut-flowers and pot variety.China the nineties in last century start from Holland,
Japan etc. introduces a fine variety, and has cultivation in a each big city as cut-flower, potting and spring flower show flower.
Ranunculus asiaticus strain appearance it is exquisite beautiful, pattern enrich it is gorgeous, it is very popular.It is miscellaneous currently with Interspecific combination
Hand over, cultivate many modern cultivars, there is polyphyll, half polyphyll, pattern is abundant, have it is white, yellow, red, bright pink, bright red, orange, purple and
The multiple colors such as brown.Some Character instabilities make a variation after several generations, it is difficult to keep merit.Some are not sent out sufficiently
Shoot the merit of parent.
Ranunculus asiaticus hybrid seeding is mainly in winter-spring season, since temperature is lower, the kind of some pairs of low-temperature sensitives, and male parent flower
Powder is less, and setting percentage is low after hybridization, and the empty flat rate of seed is high, and empty flat rate can reach 70% or more, it is difficult to it is miscellaneous to meet Ranunculus asiaticus
Hand over the needs of the production of hybrid seeds.
Summary of the invention
The invention aims to make up prior art defect, a kind of improve is provided, the quick parent Ranunculus asiaticus of low temperature sense is hybridized
The effective ways of seed quality, the setting percentage after improving hybridization.
To achieve the above object, the present invention is achieved by following scheme:
The present invention provides a kind of effective ways for improving Ranunculus asiaticus hybrid seed quality, specifically includes the following steps:
(1) parent material is planted: by Ranunculus asiaticus seed water seed soaking, with the Ranunculus asiaticus after wet cloth or towel package seed soaking
Seed, is placed in 0-4 DEG C of refrigerator and handles 5-7 days, move on to vernalization 7-10 days at room temperature, and the seed after vernalization is seeded into nonwoven
In cloth nutrient bag, normal fertilizer and water management to 4-5 piece leaf is transplanted to greenhouse together with nutrient bag, and when field planting, Parent presses 1-1.2:1
It is planted every moisture in the soil, mu plants 1200 plants；
(2) covered ground: carrying out covered ground using mulch, and mulch is carried out overlay film, weight between mulch along furrow direction
Folded 10-15cm, overlapping is compact with soil, and mulch is close to furrow, and the mulch on furrow is covered with hack to be compacted, hack thickness 1.5-
2cm；
(3) greenhouse heats: a warming-up device is added in canopy, it is ensured that night canopy temperature is not less than 5 DEG C, and daytime is not low
In 8 DEG C；
(4) male parent light filling: carrying out light filling using LED light strip, and light bar is from plant 10-15cm, light filling for 24 hours daily；
(5) hybridization pollination: the maternal emasculation before anther dehiscence, capitulum have many little Hua on floral disc, and little Hua's blooms
Phase is inconsistent, and the 3rd day after emasculation starts to pollinate, it usually needs awards 3 times；
(6) sowing: reinforcing fertilizer and water management and the prevention and control of plant diseases, pest control, picks aggregate fruit after seed development is mature, fills after drying
Enter paper bag, is placed at dry and ventilated and stores.
Preferably, seed soaking first impregnates Ranunculus asiaticus seed 10-15min with 50-55 DEG C of warm water, then Ranunculus asiaticus seed is gone to
2-4h is impregnated in 28-32 DEG C of warm water.
Preferably, mulch is black polyethylene mulch, and covering with ground sheeting rate is 100%, and mulch light transmittance is less than 10%.
Preferably, canopy temperature control is at 15-20 DEG C.
Preferably, light filling uses complex light, intensity of illumination 2000-3000Lx.
The beneficial effects of the present invention are:
(1) it first uses 50-55 DEG C of warm water to impregnate 10-15min when Ranunculus asiaticus seed-soaking, the surface of the seed can be effectively killed
Germ, pre- preventing disease and pest impregnates 2-4h in 28-32 DEG C of warm water later, can allow neutron absorption large quantity of moisture, promotes seed
Interior enzyme activation, the respiration enhancing of embryo, to improve the bud ratio of seed；
(2) the method for the present invention carries out full plastic-film-covered cultivation less than 10% black mulch film using light transmittance, and fertilizer-preserving ability is strong, protects
Water, heat insulation effect are good, while greatly inhibiting the growth of weeds；
(3) the method for the present invention, which is used, carries out light filling for 24 hours to male parent for the complex light of 2000-3000Lx according to intensity, guarantees father
This has good upgrowth situation, improves the pollen quality of male parent, maintains out the merit of male parent.
In conclusion the present invention passes through the methods of seed soaking, full plastic-film-covered cultivation, male parent light filling, and combine reasonable temperature control
System, greatly improves the setting percentage of Ranunculus asiaticus, the setting percentage of Ranunculus asiaticus reaches as high as 94.5%.
