Rapid after-ripening method of stichopus japonicus seed

Abstract

The invention relates to a plant cultivation technology and discloses a rapid after-ripening method of stichopus japonicus seed. The method comprises the following steps of: soaking seeds by using a mixed solution of 2.40-2.60mg.L<-1> gibberellin and 2.50-2.60mg.L<-1> 2,4-dichlorphenoxyacetic acid, taking the seeds out, uniformly mixing the seeds and river sand and filling the mixture into a wood trough, covering the wood trough with a plastic film, placing the wood trough in a room, and carrying out alternating temperature treatment for 105-119 days, wherein the alternating temperature treatment is carried out for 10 hours at the temperature of 22+ / -2 DEG C at daytime and carried out for 10 hours at the temperature of 8+ / -2 DEG C at night. The problems that the seeds do not sprout in the seeding year and the rooting percentage of vegetative propagation, such as cottage, is extremely low are solved, and the method has the characteristics of short after-ripening time, high operability and high germination rate. The seeds can be directly spread on a seedbed and can sprout within 22 days, the germination rate is over 94.8 percent, and the method has significance for providing high-quality seedlings for further artificial large-scale cultivation of stichopus japonicus.

Description

[0001] technical field [0002] The invention relates to a plant cultivation technique, namely a method for rapid post-ripening of japonicus japonicus seeds. Background technique [0003] In the prior art, sea cucumber ( Oplopanax elatus Nakai) alias thorn ginseng, Northeast thorn ginseng, Araliaceae sea cucumber is a perennial deciduous shrub, the whole plant contains saponin, coumarin, gum, phenolic, flavonoids and volatile oil, etc., the root bark is used as medicine, mainly for neurasthenia, mental depression, mental illness Schizophrenia, hypotension, impotence due to kidney deficiency, diabetes, etc. The number of sea cucumbers in Changbai Mountains is very rare, and only in the Changbai Mountains National Nature Reserve has a large population area, and only sporadically distributed in other areas. It is designated as an endangered species by the "List of Rare and Endangered Plants in China (Volume 1)", and it is a national second-class key protected plant. It is lis...

AI Technical Summary

Problems solved by technology

[0004] After the fruit of Apostichopus japonicus is mature, the seed embryo in the seed is in the spherical embryo stage, the seed does not germinate after sowing, and the rooting rate of asexual reproduction such as cuttings is extremely low, and the wild resources are threatened by extinction, and large-scale artificial cultivation, development and utilization are threatened. extremely restrictive

[0005] In the past studies, both temperature-changing treatment and low-temperature stratification were used to complete the two-step process, and there were disadvantages such as complicated steps, long time, low germination rate and poor operability. The goal of rapid ripening of ginseng seeds
