Jasmine blossoms spend time
The white and fragrant jasmine flower is deeply loved because of its long flowering period. Mastering its unique flowering rules and maintenance methods can keep the courtyard lingering and fragrant. As a typical tropical flower, its blooming rhythm is closely related to temperature and light. Reasonable control can realize the vision of enjoying flowers in three seasons. Three-stage blooming characteristics of jasmine flowers The first round of blooming in early summer ushered in the most intensive bloom of the year from late May to early August. When the temperature stabilized above 25℃, the buds expanded at a rate of 3-5 mm per day. The calyx can be seen opening slightly in the morning, the petals gradually stretch out in the afternoon, and the flowers that are fully blooming in the evening release the strongest aroma. The second multiple flowering in mid-autumn shows that the secondary flowering period is from mid-August to the end of September, with a decrease in flower quantity by about 40%, but the fragrance of flowers is clearer. At this stage, special attention should be paid to the regulation of the temperature difference between day and night, and the gradient change of 28 ℃ daily temperature/18℃ night temperature can promote the quality of flower bud differentiation. Characteristics of late autumn final flowering period sporadic blooms can still be seen from the end of September to before frost, and the flower diameter has shrunk to 2-3 cm. At this time, nitrogen fertilizer application should be reduced and phosphorus and potassium fertilizer should be used to enhance plant cold resistance and reserve nutrients for overwintering. Key technologies to extend flowering period Light and heat management ensures 6 hours of direct light every day, and uses sunshade nets to control noon strong light. During indoor maintenance in winter, the fill light is illuminated 50 cm away from the plant for 4 hours a day, which can extend the flowering period of a single flower to 5 days. The precise supply of water and fertilizer is used during the flowering period, and the "dry and wet" watering method is used, and the topsoil is watered thoroughly when 2 centimeters are dry. Fermented soybean cake water is applied twice a month, and potassium dihydrogen phosphate solution (concentration 0.2%) is added during the bud stage. Trim and control techniques Cut off the remaining flowers and the next two pairs of leaves in time after flowering to retain new axillary buds. Conduct sizing and pruning in mid-September to remove sick and weak branches and keep the plant type ventilated and transparent.
Through the coordinated management of temperature, light, water and fertilizer, and scientific pruning, jasmine flowers can achieve a viewing period of up to half a year. It is recommended to plant with pottery pots to improve the breathability of the roots, and regularly rotate the pots to ensure uniform light reception, so that the elegant fragrance will continue to linger in the living space.
