The invention discloses a method for regulating and controlling the flowering stage and flowering traits of cymbidium sinense. According to the method, through fertilizer and water, illumination and temperature management in the flower forcing process, a plant growth regulator mixed solution I is sprayed in the early stage of flower bud differentiation to promote flower bud differentiation to be completed in advance, and a plant growth regulator mixed solution II is sprayed again in the flower arrow elongation stage to promote flower arrow elongation and inflorescence development. By means ofthe method, the number of buds of each pot is 2-3, the number of flowers on each inflorescence is increased and is averagely three more than that of contrast, the flowers become larger, and the initial flowering period can be advanced by 24 days. According to the method, the cymbidium sinense is stabilized to bloom before the Spring Festival, the blooming quality is improved, the arrow is increased and lengthened, the inflorescence is lengthened, the number of flowers is increased, the flowers are enlarged, the ornamental effect is better, a foundation is laid for meeting the huge demand of phalaenopsis orchid, the purposes of further expanding the market and increasing the market share of the cymbidium sinense are achieved, and economic benefits are outstanding.
