The invention discloses a breeding method for aseptic seeding and
test tube seedling formation of orchids and the adopted broad-spectrum culture medium. In this method, a healthy orchid mother
plant is selected, and artificially pollinated when it blooms, and the fruit that develops to maturity after
pollination and has not cracked is used as an explant, or the orchid fruit that is basically mature and not cracked is taken from the wild as an explant. Implants undergo reproductive steps such as aseptic
sowing, seed
germination, strong
seedling cultivation, and test-tube
seedling transplantation. The specially prepared medium is used for aseptic
sowing and seed
germination to obtain small plants, and then the small plants are cultivated on the specially prepared strong seedling medium, and the seedlings are hardened under natural light in the
greenhouse for 7-14 hours before being released from the
bottle. One day, the test-tube seedlings were taken out, the root medium was washed off, and they were planted in a mixed substrate of
bark, bluestone and
peat, and further cultivated into seedlings. The invention has the characteristics of high seed
germination rate, fast seedling growth, good seedling quality, low cost, etc., can obtain a large number of test-tube seedlings in a short period of time, and the
transplanting survival rate of the seedlings can be kept above 90%. An effective way can be provided for the production of orchid seedlings.
