Embodiment 1
[0027] Embodiment 1: Dendrobium officinale seedling rapid multiplication technology
[0028] After the mature capsule seeds of wild Dendrobium officinale origin are harvested, they are placed in a clean petri dish, and after they crack naturally, the seeds are poured into a clean beaker and sealed, and stored in a low-temperature box.
[0029] After certain disinfection procedures, the stored seeds are put into the medium of MS basic medium + NAA (a-naphthaleneacetic acid) 0.4mg / L + potato juice 20% (V / V) + agar 7g / L. Germination culture. The culture temperature is 22-25°C, the light is 10 hours a day, and the light intensity is 1500-1800lx. After 2 weeks, the seeds turn green gradually, and a protocorm is formed in two months. If you look at it with a magnifying glass, you can see that the protocorm has needles to appear.
[0030] The protocorm is transferred to MS basic medium+BA (6-benzyl adenine) 0.2mg / L+potato juice 20% (V / V)+agar 7g / L medium to carry out protocorm prol...
Embodiment 2
[0032] Embodiment 2: Dendrobium candidum tissue culture seedling training technology
[0033] (1) Seedling training substrate
[0034] Wood shavings + perlite + grass carbon soil, ratio (volume ratio) 1:1:1.
[0035] (2) seedling training method
[0036] The seedling training container is a small flower pot with a height of 7 cm. Lay fine gravel with a diameter of 1 to 2 cm and a thickness of 3 cm at the bottom of the flower pot; The grass-carbon soil mixed matrix is placed on the fine gravel with a thickness of 3cm. Put 10 seedlings in each pot, open a small nest with the mixed substrate, put the roots of the plant in the nest and cover it well, expose the base of the plant, pour root-fixing water once, and control the temperature, light intensity and moisture ,humidity.
[0037] (3) Seedling training conditions
[0038]Ordinary greenhouses can be used as seedling training sheds. Seedling training sheds should be equipped with plastic film racks, openable and closed sk...
Embodiment 3
[0039] Embodiment 3: Dendrobium candidum transplanting technique
[0040] (1) Transplanting substrate
[0041] Large gravel with a diameter of 3-5 cm + fine gravel with a diameter of 1-3 cm + moss, the ratio is 4:2:1 (volume ratio).
[0042] (2) Transplanting conditions
[0043] Ordinary plastic greenhouses can be used as transplanting greenhouses. Plastic films, sunshade nets, film rolls and other devices should be installed in the greenhouses, and drainage ditches should be dug around the greenhouses. The cultivation bed should be laid in the shed, the width of the cultivation bed is 1.2m, and a 50cm wide operation path should be left in the middle. The suitable growth temperature for transplanting seedlings is 18-26°C, the highest temperature is not higher than 32°C, and the lowest temperature is not lower than 8°C; the air humidity is 75-85%, and the moisture of the substrate is better, and the substrate is too wet or dry Both will seriously affect the survival rate and...
