Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of seed seedling, and particularly relates to a seedling method of Scaphium scandens. BACKGROUND

[0002] Scaphium scandens is scientifically named as the dried rhizome of Scaphium scandens in the lily family, has the effects of removing dampness and turbidity, dispelling wind and relieving arthralgia, and resolving toxicity and removing blood stasis. Smilax china The seed of Scaphium scandens has a morphological and physiological dormancy phenomenon, that is, the seed has a deep dormancy phenomenon caused by simultaneous morphological and physiological underdevelopment, which leads to a long seedling time, a low seedling rate, and uneven seedling quality in the seedling process, and causes great hindrance to seedling. SUMMARY

[0003] Therefore, the application aims to provide a seedling method of Scaphium scandens to solve the problems of low seed germination rate and low seedling efficiency caused by seed dormancy.

[0004] In order to achieve the above-mentioned application purposes, the application provides the following technical scheme. The application provides a seedling method of Scaphium scandens, comprising the following steps. After the seed of Scaphium scandens is sterilized, the seed is placed in layers with wet sand, and stratification germination is carried out for 5-7 months; 0.3-0.8 cm-thick seed layers are laid in each 0.5-1.5 cm-thick wet sand layer, then the germinated seeds are sowed, seedlings are obtained, and the seedlings are transplanted to a field.

[0005] Preferably, the wet sand is sterilized at a temperature of 110-130 DEG C for 15-25 min, and the humidity is maintained at 40%-50% after cooling.

[0006] Preferably, the temperature of stratification germination is 20-30 DEG C.

[0007] Preferably, alcohol is used for sterilization, and the volume fraction of the alcohol is 70-80%.

[0008] Preferably, the sterilization time is 0.5-2 min, the seeds are washed with water after sterilization, and the washing frequency is 2-4 times.

[0009] Preferably, the sowing is strip sowing or broadcast sowing, and the thickness of the soil covering after sowing is 0.5-2 cm.

[0010] Compared with the prior art, the application has the following beneficial effects: 1. The method of the application can break the dormancy state of the seed, and significantly improve the germination rate of the seed.

[0011] 2. The seedlings obtained by the method of the application have strong vitality and high transplanting survival rate.

[0012] 3. The traditional method of directly stratifying the seeds of *Smilax glabra* in sand results in seeds germinating after 2 years, and seedlings need to be cultivated for 1-2 years after sowing. The method of this invention, however, significantly shortens the seedling cultivation time of *Smilax glabra* from 3-4 years using traditional methods to 1.5 years by improving seed germination rate and seedling transplant survival rate.

[0013] 4. The technical details involved in this invention are simple to operate, easy to master, and will not have a significant impact on the ecological environment. Detailed Implementation
