长效型耐荫花境的营造与养护技术探索——以上海市莘庄公园为例
Exploration of Construction and Maintenance Techniques for Long-Lasting Shade-Tolerant Flower Borders—A Case Study of Xinzhuang Park in Shanghai

本研究通过分析上海市莘庄公园花境存在的主要问题，并采用筛选适生植物、改良栽植基础和优化养护技术等方式，成功构建了一个长效可持续的花境。具体措施包括：筛选耐荫性强、观赏期长的植物品种；改良土壤结构，增加排水层和盲沟系统；优化水肥管理，采用缓释肥和叶面喷施技术。结果表明，通过合理配置耐荫植物和科学管理技术，植物年更换率从240%降低至15%，显著节约了养护管理成本。本研究可为荫蔽环境下的花境设计和日常养护提供科学依据，助力城市生态环境优化与绿色低碳发展。
This study addresses the main issues of flower borders in Xinzhuang Park, Shanghai, and successfully established a long-lasting and sustainable flower border by selecting suitable plant species, improving planting foundations, and optimizing maintenance techniques. Specific measures included the selection of shade-tolerant plant varieties with extended ornamental periods, the enhancement of soil structure by adding drainage layers and blind ditch systems, and the optimization of water and fertilizer management using slow-release fertilizers and foliar spraying techniques. The results indicate that through the rational configuration of shade-tolerant plants and scientific management techniques, the annual plant replacement rate decreased from 240% to 15%, significantly reducing maintenance costs. This study provides a scientific basis for the design and daily maintenance of flower borders in shaded environments, contributing to the optimization of urban ecological environments and the promotion of green, low-carbon development.
