Embodiment 1
[0022] Isolation of germination fungi
[0023] Seeds are sown in a suitable growth environment for bletilla striata and dendrobium to obtain seeds, protocorms and seedlings, and germination fungi are obtained by separating and screening after surface disinfection of germination materials.
Embodiment 2
[0025] Effect of Bsg14 on germination of Dendrobium officinale seeds
[0026] Sow the seeds of Dendrobium candidum on the wheat bran, leaves and sawdust that have been covered with Bsg14 fungal mycelium, and use the sterilized wheat bran, leaves and sawdust as a control, and cultivate them in a culture room at a temperature of 23-27 ℃, 12 hours of light per day, the light intensity is: 1200Lx, the seed germination situation is investigated in two months, the result is: the seed germination rate of Dendrobium candidum treated with Bsg14 fungus: 67.3%, and the seed germination of Dendrobium candidum treated without fungus The rate is 0.0%.
Embodiment 3
[0028] Effect of Bsg14 on germination of Dendrobium officinale seeds
[0029] Sow the seeds of Dendrobium candidum on the wheat bran, leaves and sawdust that have been covered with Bsg14 fungal mycelia, and use the sterilized wheat bran, leaves and sawdust as a control, and cultivate them in a greenhouse at a temperature of 15-26 °C , natural light, and the light time per eye is 8-10 hours, and the seed germination situation is investigated in two months. The result is: the seed germination rate of Dendrobium candidum treated with Bsg14 fungus: 65.1%, and the seed germination of Dendrobium candidum without fungus treatment The rate is 0.0%.
