深圳梧桐山毛棉杜鹃复壮技术研究

摘要 通过对梧桐山万花屏和杜鹃谷毛棉杜鹃立地条件调查，分析毛棉杜鹃衰弱的原因主要是植株营养消耗过剩，土壤保水保肥能力差，群落郁闭度不合理，树龄偏大老化以及气候和人为的影响，从水肥管理，郁闭度调整，土壤改良，林下更新和摘花除果等方面，提出了复壮措施。

Abstract Through the investigation of the site conditions of Rhododendron moulmainense in Wanhuaping and Dujuan Valley of Wutong Mountain，the main reasons for the decline of Rhododendron moulmainense were analyzed， including excessive plant nutrient consumption， poor soil water and fertilizer retention capacity， unreasonable community canopy closure， aging of trees， and the influence of climate and human activities. Revitalization measures were proposed from the aspects of water and fertilizer management， canopy closure adjustment， soil improvement， understory regeneration， and flower and fruit picking.
