(3) the sword orchid cultivated with cut flowers with planting density can be planted according to the standard of row spacing of 20 cm and plant spacing of 10 cm to 15 cm. The seed balls with a weight of 1215g and a diameter of 3.5cm can sow 20 000 ~ 25000 seeds per mu.

(4) the planting depth in spring is shallower than that in summer and autumn. The spring planting depth is usually 5 cm to 10 cm, and the planting depth in summer and autumn can be deepened to 10 cm to 15 cm.
