Problems solved by technology

The above-mentioned technical solutions all use the sand storage method with gradual temperature changes to stratify the seeds of notopterygium to promote after-ripening. Since the temperature needs to be strictly controlled during the treatment process, it is necessary to isolate the seeds of notopterygium from the external environment. method, it will easily lead to the increase of the quality difference between the cultivated seedlings and wild seedlings

Embodiment

[0027] The specific embodiment of the present invention is described in detail in conjunction with embodiment as follows:

[0028] This embodiment was implemented in September 2017 in the applicant's nursery base located in Neijiang City, Sichuan Province.

[0029] S1. On the shady side of the hillside of the base or where there are long-term shelters of trees, select open fields with good water to dig and set up soil pits with a diameter and depth of not less than 20cm. Put a PP flower pot with an open diameter and a height of not less than 18cm in the soil pit, so that the upper edge of the flower pot is flush with the ground.

[0030] S2. Select full-grained notopterygium seeds, use a 40-mesh nylon seed soaking bag with a size of 10cm×15cm, fill each bag with 300-400 notopterygium seeds, and seal it tightly.

[0031] S3. Put the soaking bag and the notopterygium seeds fully into the 40PPm gibberellin solution, and observe after overnight to ensure that the notopterygium se...

Abstract

The invention discloses an after-ripening treatment method of incised notopterygium seeds. The after-ripening treatment method comprises the following steps: carrying out gibberellin solution imbibition treatment, open-air hillside land burying and low-temperature wet storage operation on the incised notopterygium seeds in sequence and promoting incised notopterygium embryo development and differentiation to finish after-ripening, so as to improve the sprouting rate of the incised notopterygium seeds to be 90 percent or more. Natural sprouting conditions of the incised notopterygium seeds aresimulated through open-air hillside land burying, so as to finish shape after-ripening of incised notopterygium embryos and the quality of germchits is easy to improve after the incised notopterygiumseeds are sprouted.

Description

technical field [0001] The invention relates to a post-ripening treatment method for notopterygium seeds, belonging to the technical field of notopterygium seed priming. Background technique [0002] Notopterygium is a perennial herb of Umbelliferae notopterygii. It uses rhizomes and roots as medicine. It is warm in nature and bitter in taste. It can not only produce sweat and relieve the exterior, but also dispel rheumatism and relieve pain. Arthralgia, joint pain, bruises and other diseases. It is mainly distributed in alpine forest-shaded wetlands in the alpine regions of Sichuan, Qinghai, Gansu, Tibet and other provinces. [0003] Because notopterygium seeds are post-ripening dormancy type, that is, immature embryos and immature seeds are double dormancy. Therefore, under natural conditions, notopterygium seeds need one year to germinate, and the natural germination rate is extremely low. In recent years, relevant planting enterprises and scientific researchers have ca...
