Provided is a
greenhouse cultivation method for butterfly orchid. Aquatic plants are washed by
clean water and disinfected and sterilized, so that a butterfly orchid
nutrition pot substrate is obtained;
bud arrows of the butterfly orchid are
cut and then placed in a
tissue culture chamber to be planted, after the
bud arrows are cultured to seedlings through
tissue culture and are divided, the temperature,
humidity and illumination are controlled, and the
bud arrows enter a root cultivation period after a
tissue culture period
ranging from 12 months to 13 months; in the root cultivation period, when three roots of the butterfly orchid are completely filled, the butterfly orchid is transplanted into a
transplantation pot with the
diameter of 3.0 cun, when 4-5 roots grow to be filled, the butterfly orchid is transplanted into a
transplantation pot with the
diameter of 3.5 cun, vegetative growth cultivation is carried out, and the butterfly orchid enters an arrow urging period after the root cultivation period
ranging from 5 months to 6 months; in the arrow urging period and a flower growing period, the temperature,
humidity and illumination are controlled, cultivation time of the whole arrow urging period ranges from 45 days to 60 days, and cultivation time of the whole flower growing period ranges from 5 days to 8 days. The method has the advantages that the
survival rate of the butterfly orchid is high and more than 90%, the cultivation period of the butterfly orchid is shortened, and the method is suitable for
greenhouse cultivation of the butterfly orchid in the north.
