Embodiment 1
[0047] Step 1, selection and processing of explants
[0048] Select the leaves of the orchid as starting material, and use them as explants for tissue culture after disinfection;
[0049] Step 2, induction of protocorm-like
[0050] On the ultra-clean workbench, transfer the surface-sterilized explants to a sterile inoculation tray, blot the surface moisture of the explants with sterile filter paper, and use sterilized scissors to insert the leaf base down into the protocorm Cultured on the induction medium MS+TDZ5.0mg / L (TDZ: thiadizuron), 20 days later, a yellow embryogenic callus was formed at the base of the leaf, and after another 20 days, it turned from yellow to green, forming a small green ball, which resembled Protocorm formation;
[0051] Step 3, proliferation of protocorm-like
[0052] The protocorm-like formed in step 2 is transferred to the protocorm-like proliferation medium MS+6BA2.0mg / L (6BA: benzylaminopurine) for cultivation, and the protocorm-like prolife...
Embodiment 2
[0058] Step 1, selection and processing of explants
[0059] Select the leaves of the orchid as starting material, and use them as explants for tissue culture after disinfection;

[0061] On the ultra-clean workbench, transfer the surface-sterilized explants to a sterile inoculation tray, blot the surface moisture of the explants with sterile filter paper, and use sterilized scissors to insert the leaf base down into the protocorm Cultured on the induction medium MS+TDZ5.0mg / L (TDZ: thiadizuron), 20 days later, a yellow embryogenic callus was formed at the base of the leaf, and after another 20 days, it turned from yellow to green, forming a small green ball, which resembled Protocorm formation;
[0062] Step 3, proliferation of protocorm-like
[0063] The protocorm-like formed in step 2 is transferred to the protocorm-like proliferation medium MS+6BA2.0mg / L (6BA: benzylaminopurine) for cultivation, and the protocorm-like prolife...
Embodiment 3
[0069] Step 1, selection and processing of explants
[0070] Select the leaves of the orchid as starting material, and use them as explants for tissue culture after disinfection;
[0071] Step 2, induction of protocorm-like
[0072] On the ultra-clean workbench, transfer the surface-sterilized explants to a sterile inoculation tray, blot the surface moisture of the explants with sterile filter paper, and use sterilized scissors to insert the leaf base down into the protocorm Cultured on the induction medium MS+TDZ5.0mg / L (TDZ: thiadizuron), 20 days later, a yellow embryogenic callus was formed at the base of the leaf, and after another 20 days, it turned from yellow to green, forming a small green ball, which resembled Protocorm formation;
[0073] Step 3, proliferation of protocorm-like
[0074] The protocorm-like formed in step 2 is transferred to the protocorm-like proliferation medium MS+6BA2.0mg / L (6BA: benzylaminopurine) for cultivation, and the protocorm-like prolife...
