Family flowering flowering regulation method

1. Increase the temperature. Flowering flowers depend on the differentiation of internal flower buds and the external temperature and light. Some spring flowers such as peaches, sea leeks, redbud, plum, forsythia, clove, spring, peony, azalea, etc., have been completed in early winter, but the flower buds have been forced to sleep due to low temperatures. May bloom during the Spring Festival and Lantern Festival. To raise the temperature of flowers in the family: 1 Place the pot on the sill of the sun room and place it on the floor about 1m away from the heat source in the evening; 2 Place a transparent plastic film cover on the flowers and plants that need to be warmed up. Leave a narrow slit in the contact area and remove the hood in the evening. 2. Change the lighting. Short-day flowers, flower buds can be differentiated when the sunshine time is shorter than 12 hours. The method of shading treatment is to limit the daily illumination time to 9 to 10 hours, which can promote flowering. 3. Use plant growth regulators. The role of plant growth regulators is to promote flower bud differentiation and increase flower numbers. For example, with the gibberellin 0.05% ~ 0.1% solution smeared tea plum, white magnolia, camellia, smiling, peony buds, Chamei, Magnolia can be 1 to 2 months ahead of flowering, Camellia can be 2 to 3 months ahead of flowering, Smiles can be flowered 3 to 4 months in advance, and peony can bloom 5 to 6 months in advance. A string of red was sprayed with a 0.002% gibberellin solution and a new inflorescence was withdrawn after 4 to 5 days. The flowers and trees used to adjust the flowering period must grow robustly, and the water and fertilizers should be properly maintained. Also pay attention to timely and proper ventilation.
