Embodiment 1

[0023] A method for seedling cultivation of bletilla striata seeds by direct seeding, comprising the steps of:

[0024] Step A Seed harvesting: After the purple-green shell of Bletilla striata seeds fades, the whole plant is sprayed with foliar fertilizer (multi-element foliar fertilizer produced by Shike Biotechnology Shanghai Co., Ltd.) and potassium fertilizer (the quality of potassium dihydrogen phosphate and water The ratio is 1 to 1000); when the shell of the seeds turns yellow, harvest them together with the flower stems in the afternoon on a sunny day, dry them in a ventilated and shaded place for 5-12 hours, then soak the seeds in cold water for 7 days, change the water once a day, and soak the seeds Dry the surface moisture, store in sand at low temperature, according to the ratio of sand: seeds 3:1, and the storage period is within 8 months;

[0025] Step B seed medicine treatment:

[0026] (1) Seed sterilization: Immerse the Bletilla striata capsules prepared in s...

Embodiment 2

[0035] A method for seedling cultivation of bletilla striata seeds by direct seeding, comprising the steps of:

[0036] Step A Seed harvesting: When the shell of the seeds turns yellow, harvest them together with the flower stems in the afternoon on a sunny day, dry them in a ventilated and cool place for 5-12 hours, then soak the seeds in cold water for 7 days, change the water once a day, and dry the seeds on the surface after soaking. Dry with water, store in sand at low temperature, according to the ratio of sand: seeds 3:1, the storage period is within 8 months;

[0037] Step B seed medicine treatment:

[0038](1) Seed sterilization: Immerse the Bletilla striata capsules prepared in step A with 75% alcohol for 30 seconds, rinse them with sterile water, and then disinfect them with 5% sodium hypochlorite solution for 10 minutes. Blot the water on the surface of Bletilla striata capsules with filter paper; (2) Prepare hormone medicine: 1 / 2 MS liquid medium + 3mg / L DA-6 ami...

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a method for live seedling cultivation of bletilla striata seeds. Background technique [0002] Bletilla striata (Thunb.) Reiehb.f., a perennial herb of the genus Bletilla (Bletilla) in the family Orchidaceae, with dried tubers used as medicine, has the effects of astringent and hemostasis, detumescence and muscle growth. Modern pharmacological experimental studies have shown that Bletilla striata also has pharmacological effects such as anti-tumor and antibacterial. In addition, Bletilla striata is widely used in landscaping, food processing and industrial raw materials. In recent years, the market demand for bletilla striata raw materials has risen rapidly, and wild bletilla striata has been wildly excavated, resulting in a sharp decrease in its wild resource reserves, and it is on the verge of extinction. It is listed as one of the wild medicinal plants ...
