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%.
