The flower bud differentiation period of Cymbidium hybridum is from June to October. In order to overcome this problem, it can be moved to the mountain above 8 ~ 1m above sea level for cultivation, and the day temperature is kept at 2~25℃ and the night temperature is kept at 1~15℃, so as to facilitate the formation of flower buds. Generally, the earlier the mountain time, the earlier the flowering. The specific time should be based on the flowering habits of different varieties. High temperature shortens the flowering period < P > Cymbidium is a long-day flower, and the illumination time is appropriately extended; During flower bud differentiation, proper water control to keep the soil dry can promote flower bud differentiation and inflorescence formation, so that it can bloom early. In production, it can also inhibit its vegetative growth and accelerate reproductive growth by reasonable fertilization and bud shaping.
