DPC, also known as Chuananan or CCC, is a plant growth regulator. Production practice has proved that proper and proper use of DPC can shape a reasonable cotton plant type and field population structure and form an ideal distribution of bolls, thus obtaining better yield-increasing effects and economic benefits. First, the use of the results 1. Promote the role of cotton preculture yield. Such as Jimian No. 2 flourishing bud in the long, with 50PPm spray, flowering in the same concentration spray again, the results boll per plant more than the control 1.4,
