today, from the Ji'nan city landscape and Greening Bureau, the city has recently emerged as a big city. The city garden Bureau invited a number of famous domestic bamboo experts to carry out professional consultation. On the basis of analyzing the main reasons and combining experts and suggestions, a number of scientific measures have been formulated.
according to statistics, the total number of bamboo planted in Ji'nan City area is about 78 thousand square meters, mainly in bamboo. Since April, the leaves of bamboo forests in the city are yellow and blooming. At present, the area of the flower bud differentiation of the bamboos has reached 80% of the total, and is rising with the increase of the temperature.
to explore the reasons for the flowering of bamboo, further formulate scientific and reasonable measures. In April 18th, the Ji'nan municipal garden Bureau invited Gu Xiaoping, chief researcher of the Institute of Subtropical Forestry of China Forestry Academy, Ding Yulong of Nanjing Forestry University, and Wang Fusheng, director of the Bamboo Research Institute of Nanjing Forestry University, at home and abroad. The bamboo research experts consulted and analyzed the flowering phenomenon of bamboo in Ji'nan. According to expert analysis, there are two reasons for the flowering of Phyllostachys glauca. According to the internal cause, Phyllostachys glauca is a perennial plant of bambooaceae, and its flowering period is generally 20-60 years. The bamboo forest with large flowering area in the city is basically regenerated bamboo. The source of the species is mostly from the same origin, the introduction time has been over 50 years, and its life cycle has come to the later period. This flower is the normal phenomenon of self renewal after the light bamboo enters the physiological maturity period. According to external factors, since last autumn winter solstice this spring, Ji'nan continued to be dry and drier. Although the parks and garden departments have strengthened the water and drought resistance of the seedlings, the bamboo likes the warm and humid climate, the continuous dry climate, to induce the bamboo to enter the physiological maturity in advance.
bamboo will generally die after 1 to 2 years of flowering. The natural recovery period will take about ten years. This will have a great impact on the landscape of bamboo forests in Ji'nan. In order to speed up the restoration of bamboo forest landscape in this city and ensure the safety of bamboo germplasm resources in Ji'nan City, the municipal garden Bureau has formulated four measures according to the experts' suggestion and combined with the actual situation to scientifically deal with the flowering of the bamboo.
is properly updated according to local conditions. According to the actual situation of the existing bamboo forests in the park area and the urban green space, starting from the ecological emergency restoration project, the renewal scheme was formulated, and the city garden scientific research institute was entrusted with the introduction of other bamboo species with higher ornamental value to replace the existing light bamboo, increasing the diversity of the bamboo forest landscape in Ji'nan, and strengthening the maintenance and management of the existing bamboo forests and taking care of the existing bamboo forests. Bamboo shoots, bamboo planting and Hsinchu planting were used to maintain landscape during the alternate period of new and old bamboo species.
based on the long-term, key breakthroughs. In order to give full play to the theoretical support and technical support of science and technology to urban greening construction, it is led by the city garden Scientific Research Institute, and a special project group has been set up by the Subtropical Forestry Institute of China Academy of forestry and the Bamboo Research Institute of Nanjing Forestry University to carry out the research on the introduction of bamboo germplasm resources and the restoration of bamboo landscape. At the same time, in order to realize the optimal allocation of scientific and technological resources, the scientific research base of the city garden scientific research institute is used as the base of introduction, domestication and breeding of bamboo germplasm resources. The spring city park and botanical garden are used as the test and demonstration base for the new excellent varieties. The zoo is the base of the bamboo species of the giant panda, and the other park scenic spots are used as the bamboo garden. The demonstration area of landscape construction has jointly accelerated the research of bamboo research projects and the transformation of scientific and technological achievements in Ji'nan.
introduce talents and increase investment. The bamboo flowering has a great impact on the landscape of urban bamboo forests, but it also provides an opportunity for research, breeding and breeding of new varieties of Phyllostachys glauca. The city garden Bureau will combine the Ji'nan talent introduction plan, special introduction of bamboo research senior technicians, invites domestic bamboo research experts, actively carry out the training work of bamboo conservation and management technology, and actively apply for the support of special scientific research funds for national, provincial and municipal scientific and technological development while supporting special scientific research funds. Scientific research projects are successfully implemented.
strengthen guidance and widely publicize. Give full play to the positive role of public opinion propaganda and social mobilization, increase the education of science popularization, guide the citizens to understand the phenomenon of bamboo blossom correctly, and mobilize the bamboo planting units and communities in the city to take scientific and effective measures to carry out the management of bamboo forest and post flower restoration.
