Embodiment 1
[0028] Select isolated pinellia tubers with a diameter of 0.6-0.8cm from plant tissue culture, moderate length, high survival rate, easy operation, rinse with water for 3 times, sieve and wash with 8 meshes, and remove impurities on the surface of isolated pinellia tubers. Prevent bacterial infection, obtain fresh and directly plantable isolated pinellia tuber fresh products, and plant directly in the right season without storage; in the mixed solution of 25mg / L commercial rooting powder and 100mg / L agricultural streptomycin Soak in medium for 3 hours, control the soaking temperature at 24±3°C, and soak at the appropriate concentration and temperature of the mixed solution to avoid infection of Pinellia isolated tubers with various diseases and insect pests; choose river sand as the substrate in the germination and rooting medium, and the investment cost is low , easy to operate and easy to manage. Under the conditions of 121°C and 0.1Mpa, high temperature and high pressure dam...
Embodiment 2
[0030] The difference from Example 1 is that the concentration of commercial rooting powder is 100mg / L, and the concentration of agricultural streptomycin is 150mg / L. After 15 days of cultivation, the emergence rate is 99.98%.
Embodiment 3
[0032] The difference from Example 1 is that the culture conditions of the germination and rooting medium are: light intensity 2500 lux, light 18 h / d, temperature 25±1°C; after 15 days of culture, the emergence rate is 99.96%.
