城市森林建设背景下的公园绿地养护探索与实践

Exploration and Practice of Park Green Space Maintenance Under the Background of Urban Forest Construction

以莲花池公园城市森林示范区为例,根据城市森林的特点,对标《城镇绿地养护技术规范》等规范性文件,阐述了城市森林建设背景下的公园绿地养护探索与实践,并提出了相应养护措施:①推广节水喷灌系统并减少开堰浇水对地被植物的破坏;②有选择地保留乡土地被植物并适当中耕除草;③观叶树种中易伤流的树种选择秋末叶落尽前修剪并涂愈合剂,松树选择早春萌芽前留橛修剪并于当年秋季去除;④冬春季节可在水体中并保留苇丛或在隐蔽处搭建鸟类饮水平台供鸟类栖息停留并补充水分,防止啄木鸟啄食伤流树种树液;⑤根据乡土植物定植的位置按照其生长特性选择合适的修剪方法,重要景观节点的乡土树种重点修剪;⑥利用修剪下来的枝条创作生态景观小品;⑦园路及周边落叶缓扫,干枯观赏草缓割,结合浇冻水湿化处理。远离园路的落叶适当保留,观赏草次年早春割除,并收集粉碎堆肥处理;⑧园林绿化废弃物粉碎制作有机覆盖物或堆肥腐熟返还绿地;⑨优先采用物理、生物防治手段进行病虫害的生态治理。

Taking the urban forest demonstration area of Lianhuachi Park as an example,according to the characteristics of urban forest,this paper expounds the exploration and practice of park green space maintenance under the background of urban forest construction,and puts forward the corresponding maintenance measures:①Water-saving sprinkler irrigation system should be promoted and the damage of ground cover plants caused by weir irrigation should be reduced;②the rural land cover plants should be selectively retained to appropriately plough and weed;③The tree species with easy bleeding in the foliage tree species were selected to trim and apply the healing agent before the leaves fell at the end of autumn,and the pine trees were selected to trim before the germination in early spring and removed in the autumn of the year;④In winter and spring,the reeds can be retained in the water body or the bird drinking water platform can be built in the hidden place for the birds to stay in the habitat and replenish the water to prevent the woodpeckers from pecking the sap of the bleeding tree species;⑤According to the location of native plants,the appropriate pruning method is selected according to their growth characteristics,and the native tree species of important landscape nodes are mainly pruned;⑥the pruned branches are used to create ecological landscape sketches;⑦The garden road and surrounding leaves are slowly swept;dry ornamental grass is slowly cut;and wet treatment is combined with pouring frozen water.The fallen leaves away from the garden road should be kept properly,and the ornamental grass should be cut off in early spring of the next year,and the compost should be collected and composted.⑧Landscaping waste is crushed to make organic mulch or compost and returned to green space;⑨Physical and biological control methods are preferred for ecological control of pests and diseases.
