Flower change flowers look forward to the Olympics
“A string of red flowers is a common flower used in large-scale events in Beijing. Normally, its flowering period is generally in May and October. If it is to be 'unusually' in full bloom in August, from sowing, seedling growth and migration Pot cultivation, pruning and flower control, each process has strict technical requirements." The director of the Beijing Science and Technology Department of the Landscaping Bureau of Beijing Municipality, Xu Jia, has been engaged in flower breeding and cultivation for many years. Since 2005, she and technicians have selected 586 species of Olympic flower alternatives. They are also going to let these flowers bloom in full bloom in the hot August. In August, the weather was very hot and humid. At this time, the flowers that can be opened are actually very few. So, how can we make the Beijing Olympics season colorful? How can these flowers bloom in different months in full bloom in August? A string of red flowers are commonly used in large-scale events in Beijing. Under normal circumstances, its flowering period is generally in May and October. If you want to make it "unusual" in full bloom in August, from the sowing, seedling growth, transplanting, planting, to pruning, control flowering, each process has strict technical requirements. It takes 4-6 weeks for a bunch of reds to grow from sowing to seedlings; it is also necessary to move the seedlings to the pot until flowering takes another 6-8 weeks. In this way, its entire growth cycle is 10-14 weeks. Therefore, sowing at a suitable time becomes an important technique for cultivating a string of red. "However, with August flowers, only planted 10-14 weeks ahead of time, then may not be able to get a satisfactory target flowering period." Director Xu Jia sold the customs. It turned out that in addition to "adjusting the sowing period," a string of red transplanting time must be strictly controlled. Since a string of red seedlings grows slowly, it is best to transplant the seedlings when the leaves of the seedlings grow to 4-5, and also to ensure that there is enough organic fertilizer in the transplanted soil. After transplanting, drench it with water. The string of reds entering the "seedling stage" is very easy to "sweep up" in summer when the environment is hot and humid. "If the plant grows too high, it will be unstable, unattractive, and easy to fall. If you move such a plant outside, it will be terrible if it rains. Therefore, we must spray it with plant growth regulators to inhibit its growth. , Let the plants grow 'Dandish' some, so it is easy to form a bud.†Director Xu Jia introduced many years of experience in flower cultivation. Therefore, the staff began to spray a bunch of red growth regulators 7-10 days after the seedlings were transplanted; a week later, they were sprayed a second time. Of course, it is also possible to artificially control its flowering period by performing "plastic surgery" on a string of reds by "picking buds." In the condition of 20°C-25°C, 25 days after the flower buds are removed, the plants can incubate new buds and blossom again. For example, if you want flowers to open on August 1, you can pick them off before July 5. "Overall, it is through the latest technological measures to change the flowering period of flowers and control their opening hours," explained Director Xu Jia. “Currently, cultivation techniques such as adjustment of sowing date, application of growth regulators, and pruning and shaping are all applicable to every type of Olympic flower, but each species must also be 'instructed in accordance with their aptitude' and not all of them can be applied. Therefore, every kind of flower is planted. Processes and technical applications have been tested repeatedly and eventually succeeded." At present, the cultivation and cultivation of 586 kinds of Olympic flowers have been carried out in many flower bases in Beijing. In August, these Olympic flowers will be shaped into three-dimensional shapes of various sports icons, or be designed to be used in various parks and large public places to form a variety of plant landscapes. Yao Shicai, director of the Seedling Research and Development Center of the Beijing Institute of Garden Science, told reporters that commonly used flowers, such as petunias and four-seasoned sea breams, have now cultivated seedlings. The price of each plant is about two cents. In terms of cultivation, only technicians are required. With the method taught by the professor, you can bloom beautiful flowers as scheduled.
