提升上海地区樱花生长和观赏性的路径初探

Exploration of the Pathways to Enhance the Cherry Blossoms Landscape in Shanghai

摘要: 樱花具有高观赏价值，但在上海地区不仅存在较大的栽培养护困难，还存在秋季提早落叶及不能较好变色的问题。本研究基于前期研究基础，采用配方结构配方土对上海植物园不同生长状态的樱花植株进行重新栽植，跟踪分析结构配方土对其耐水湿、生长、落叶以及秋季变色情况的影响。同时，调查上海植物园周边绿地不同栽植模式下东京樱花生长、落叶和变色情况。结果表明，结构配方土和一层树池(池高42 cm)均能较好地改善樱花生长、延缓秋季落叶、并提升秋季景观。因此，本文初步探讨了优化樱花栽种模式的新路径，希望改善樱花叶片叶色并延缓落叶，展现其应有秋色景观，全面体现樱花园林应用价值。

Abstract: Cherry blossoms possess high ornamental value, yet their cultivation in Shanghai faces significant challenges, including premature autumn defoliation and poor foliage coloration. Building on prior research, this study transplanted cherry trees of varying growth status at Shanghai Botanical Garden using a structural mixed soil. We monitored its effects on water logging tolerance, growth dynamics, defoliation patterns, and autumn color development. Concurrently, we evaluated the growth, defoliation, and coloration of Tokyo cherry blossoms under different planting regimes in adjacent urban green spaces. The results showed that the structural formula soil and a layer of tree pool (pool height 42 cm) could better improve the growth of cherry trees, the autumn defoliation, and enhance the autumn landscape. Therefore, this paper initially explored a new path to optimize the planting model of cherry trees, hoping to improve the leaf color cherry tree leaves and delay the defoliation, to show its due autumn color landscape, and to fully reflect the forest application value of cherry trees.
