Method for regulating and controlling florescence and flower quality of chrysanthemum in cold and arid region by hormone

The invention discloses a method for regulating and controlling the florescence and flower quality of chrysanthemum in a cold and arid region through hormones. The method comprises the following specific steps of female parent nutrition reproduction, twig cutting, seedling transplanting, field planting, hormone regulation and control after field planting and hormone regulation and control in the florescence. Humic acid is a mixture of macromolecular organic compounds which are formed by accumulation of remains of animals and plants through decomposition and conversion of various microorganisms and various complex biochemical reactions, are composed of aromatic substances and various functional groups, and can stimulate plant growth, improve the utilization rate of nitrogen fertilizer and plant biological activities, and improve the nitrogen fertilizer utilization rate and the plant biological activity. The drought resistance and cold resistance of the plant are enhanced; according to the chrysanthemum treated
