Main points of feeding: after deep ploughing, raise the bed and apply sufficient basic fertilizer. Propagate with underground stem bulbs, such as under Qingming Festival, the Beginning of Autumn could be enlightened. During the growing period, the suitable temperature was 22-28 ℃, and the soil should be kept moist by topdressing dilute nitrogen fertilizer for 1-2 times.
