Seedling-growing method of Salvia Miltiorrhiza Bge seeds

The invention discloses a seedlings-growing method of Salvia Miltiorrhiza Bge seeds. The method comprises the following steps: step1, harvesting seeds, uprooting the whole Miltiorrhiza Bge when more than two thirds of the ears of Salvia Miltiorrhiza Bge become yellow, aligning the roots of Salvia Miltiorrhiza Bge and making small bundles, storing the bundles of Miltiorrhiza Bge in a cool and ventilated place vertically, and drying them in shady place and collecting seeds, step 2, placing seeds in 0.1-0.3% of cellulase solution or 0.1-0.3% of pectase solution when the collected seeds are air-dried, processing the seeds by ultrasonic wave at the temperature 25-30 DEG C for 60 seconds, wherein period ultrasonic time is 2 seconds, interval time is 2 seconds; step 3, storaging seeds, soaking the seeds processed by ultrasonic wave in 1-2% of chitosan solution for 4-5 minutes, and then preserving them at 4 DEG C after drying them,step4, sowing seeds, wherein the sowing is from the last ten-days period of September t
