The invention discloses a
dendrobium officinale
bonsai cultivation method. The method comprises the following steps of 1, selecting seedlings of
dendrobium officinale, putting a cultivation medium into a pelelith
flowerpot, and then planting the seedlings of
dendrobium officinale into the pelelith
flowerpot; 2, conducting water and
fertilizer management; 3, adopting and spraying a 500-2,000 fold
paclobutrazol solution with the effective component content accounting for 15% to the plants 1-3 times every 15-20 days at least 7 days after the seedlings of
dendrobium officinale are transplanted. By means of the
dendrobium officinale bonsai cultivation method, the pelelith
flowerpot serves as a cultivation container of
dendrobium officinale, since the inside of pelelith has many pores, partial water can be stored and then slowly released to the cultivation medium, the
humidity of the medium can be effectively maintained, as is tested, the watering period can be prolonged by 3-7 days under a common indoor environment, and the manual watering frequency is effectively lowered. By spraying
paclobutrazol multiple times, the
joint spacing of dendrobium officinale is effectively reduced, the situation that dendrobium officinale gets spindling due to insufficient illumination is prevented, and thus the overall ornament value of dendrobium officinale is increased.
