The invention discloses an efficient
Bletilla striata seed propagation technology. The efficient
Bletilla striata seed propagation technology mainly includes the steps of firstly, preparing tools which include an
ultraviolet sterilizing box, a seed soaking
jar, a cultivation
jar, filter cloth, a
ceramic plate, fine sand and a spoon, and sterilizing the tools for standby; secondly, taking an iodinetincture with the concentration being 1.2%, sterilizing
Bletilla striata seeds in the
iodine tincture for 2-3 minutes,
fishing out, cleaning with cold boiled water, and naturally
drying; thirdly, sterilizing the dried
Bletilla striata seeds with
ultraviolet for 10-12 minutes, and taking out; fourthly, adding cleaning water into the seed soaking
jar, adding 2% of
sucrose, 0.9% of NaCl and 20% of potato juice, performing high-temperature sterilizing, and cooling to 28-30 DEG C; fifthly, wrapping the sterilized
Bletilla striata seeds with the filter cloth, soaking the filter cloth containing theBletilla striata seeds into the seed soaking jar for 1-2 hours, and then placing the soaked filter cloth containing the
Bletilla striata seeds into the cultivation jar to perform
germination acceleration for 3-4 days at 30-33 DEG C; sixthly, flatly laying the sand after high-temperature sterilization on a floor in a sterile room, spreading the Bletilla striata seeds after the
germination acceleration on the sand, spreading a layer of sand 0.5cm in thickness on the surfaces of the seeds, slightly compacting, and spraying a 0.5%
urea sterilizing solution until
water content is 30%.
