Method for processing fall seeding seed of Sichuan fritillary bulb

Abstract

The invention belongs to crude drug cultivation field, which in detail relates to a method for treating Sichuan fritillary bulb seed for autumn sowing. The method comprises following steps: (1) selecting plump seed harvested in the same year, mixing treated seed with soil, storing at dark and humid condition for 3- 15 weeks; (2) immersing seed with activol solution with concentration of 10 -80 ppm; (3) airing and sowing immersed seed. The method is characterized in that the rate of emergence is as high as 88%, the survival rate of seedlings in one year reaches above 75%, the seed availability rate is increased, Sichuan fritillary bulb production is increased and it is simple and suitable to be used in field.

Description

technical field [0001] The invention belongs to the field of plant cultivation, and in particular relates to a method for treating the autumn sowing seeds of Fritillaria sichuanensis. Background technique [0002] Fritillaria fritillaria is the dry bulb of various plants of the genus Fririllaria L. in the family Liliaceae. It is a commonly used famous and precious Chinese medicinal material. It tastes bitter, sweet, and slightly cold in nature. It has the functions of clearing away heat and moistening lungs, reducing phlegm and relieving cough. It is distinguished from other fritillary medicinal materials by its unique curative effect. One of the authentic Chinese herbal medicines produced in Sichuan. "Pharmacopoeia of the People's Republic of China" records that Fritillaria fritillaria is Liliaceae plant Fritillaria cirrhosa D.Don, Fritillaria unibracteata Hsiao et K.C.Hisa, Fritillaria przewalskii Maxim. The dried bulbs of Fritillaria delavayi Franch., and these several ...

AI Technical Summary

Problems solved by technology

[0003] At present, the artificial cultivation of Fritillaria is mainly carried out by using its bulbs for vegetative propagation, but this method is costly and technically difficult, and is not conducive to the maintenance of the characteristics of Fritillaria fritillata itself.

The use of its seeds for sexual reproduction is still an artificial method for Fritillaria sichuanensis, although it is plagued by problems such as difficult to break seed dormancy, low emergence rate, long time for seedling preparation, unsatisfactory seedling growth, and low rate of seedling preservation for one year. Important Development Direction of Cultivation Technology

A kind of method that 20~40ppm is used to process Fritillaria sichuan seeds to improve germination rate and shorten the time of Qi seedlings is provided in the study of gibberellin treatment of Fritillaria chinensis seeds (Journal of Grassroots Traditional Chinese Medicine, Volume 8, No. 1, 1994), but this The method also has problems such as the long time for seedling preparation, the unsatisfactory growth of seedlings, and the low rate of seedling preservation for one year.
