Abstract
The invention provides a method for breaking dormancy of cardiocrinum giganteum seeds and promoting germination thereof. The method is characterized by comprising the following steps: harvested seeds are buried into turfy soil with water content of 60-80 percent at 20-30 DEG C in the daytime and 10-20 DEG C in the nighttime for 50-70 days, then the seeds are kept for 50-70 days at 10-20 DEG C in the daytime and 0-10 DEG C in the nighttime, and finally the seeds are kept for 50-70 days at 0-10 DEG C in both daytime and nighttime; and during the course, the water content of the turfy soil is kept to be 60-80 percent till the seeds germinate for sowing in time. The dormant period of the cardiocrinum giganteum seeds can be greatly reduced from 17-18 months to 6 months, and the germination of the cardiocrinum giganteum seeds is significantly promoted by simple temperature control, the germination rate reaches over 90 percent, buds have the same length, and the method is beneficial to the improvements of plant growth rate and uniformity and saves the breeding cost.
Description
Technical field
The present invention relates to a kind of method that promotes plant germination, especially a kind of method of abolishing its germination of giant lily seed dormancy promotion belongs to field of plant growing technology.
Background technology
Giant lily (Cardiocrinum gigantieum) is that the Liliaceae giant lily belongs to the perennial bulb class herbaceous plant of (Cardiocrinum), because of the huge property of its plant significantly is different from lily, thereby is named and is " giant lily ".Giant lily causes a gardening sensation after introducing Europe immediately, is described as " lily prince ".The pure white beauty of giant lily flower, and delicate fragrance is pleasant, every strain blossom 10-20 (surplus can reaching 40 sometimes piece); It is beautiful that its blade is very large and bright, and plant height reaches 1.5～3 meters when blooming, comparatively grand, especially under wild state, has more high ornamental value, can directly be used for flower garden greening and potted plant viewing and admiring.In addition, the bulb of giant lily is rich in starch and other multiple nutritional components, can be edible, and its fruit also can be used as medicine, and is commonly called as " pocket bell ", has clearing lung-heat, relievings asthma and the effect of cough-relieving, is used to treat cough, asthma, pulmonary tuberculosis, spitting of blood and ear rhinitis and other disease.
The seed production of giant lily is very high, and the seed amount that every strain is produced reaches thousands of grains grains extremely up to ten thousand, and seed is as important organ of multiplication, and its reproduction coefficient is high, helps the introduction and acclimatization of giant lily and popularization rapidly.But, behind the giant lily seed maturity, arranged the very long deep-sleep phase; Annual October to November is ripe under the natural conditions; But just begin rudiment March to the April that will arrive the 3rd year, resting stage reaches 17 to 18 months, and it is extremely irregular to sprout; Bud ratio is low, thereby has influence on the introducing and planting and the popularizing planting of giant lily.The relevant giant lily seed dormancy of breaking promotes the method for seed sprouting not see public reported as yet.
Summary of the invention
Long for overcoming the giant lily seed dormancy phase, problem such as bud ratio is low, and it is irregular to sprout, the present invention provides a kind of method of abolishing the giant lily seed dormancy and promoting the giant lily seed sprouting.
The present invention accomplishes through following technical proposal: a kind of method of abolishing short its germination of giant lily seed dormancy; It is characterized in that: it is in 60～80% the turfy soil that the seed after will gathering is imbedded water content; Temperature is 20～30 ℃ by day; Nocturnal temperature is under 10～20 ℃ the condition, to keep 50～70 days; Temperature is 10～20 ℃ by day afterwards, and nocturnal temperature is under 0～10 ℃ the condition, to keep 50～70 days; Again by day, nocturnal temperature is under 0～10 ℃ the condition, kept 50～70 days; Control the turfy soil water content during this time between 60～80%, sowing in time behind seed sprouting.
Remove empty flat seed and impurity behind the said seed collection, stay full seed subsequent use,, improve percentage of seedgermination to guarantee seed quality.
Said turfy soil is commercial product, and the length of embedment of seed in turfy soil is 3～5cm, is beneficial to germinate.
Said turfy soil water content control is: detect the turfy soil water content weekly one time, be lower than at 60% o'clock, moisturizing in time.
The present invention compared with prior art has advantage and effect: adopt such scheme, not only with the giant lily seed dormancy phase by original 17～18 months, foreshorten to 6 months; And can promote the giant lily seed sprouting greatly through the control of simple temperature, its germination rate is reached more than 90%, and it is neat to sprout; It is good and comparatively neat after planting to emerge; Help improving plant strain growth rate and vigorous, neat rate, effectively shorten growing-seedling period, practice thrift seedling cost, do not waste seed and manpower; Be convenient to field management simultaneously, fundamentally solved long, the difficult problem of germinateing of giant lily seed dormancy phase.
