After depending on the soil fertilizer, topdressing 1 ~ 2 times, when the flower stem to 10 cm long can be applied once, for inflorescence growth; In winter, after the death of the ground, it is applied again to promote tuber growth. The elongation of flower stems has a great relationship with air humidity. High planting density and excessive dryness are not conducive to the growth of flower stem elongation.
