三角梅在海口市羊山地区生态适应性研究

Study on Ecological Adaptability of Bougainvillea in Yangshan Area of Haikou City

以紫花三角梅、红花三角梅2个海南地区常见栽培品种为试验材料,研究了三角梅在海口市羊山地区的抗旱性、抗风性等生态适应性,结果发现防风、保水是羊山地区种植三角梅的关键因素。紫花三角梅和红花三角梅在海南地区夏季有一定的耐旱和耐热性,地面有效积温过高易引起死亡,冬季可露地安全越冬,受逆境胁迫时叶片最先表现出受害状态。同时,研究发现带盆入土种植三角梅利于成花。

Using common cultivars of purple Bougainvillea and safflower Bougainvillea as experimental materials in Hainan Area,drought resistance and wind-resistance of Bougainvillea was mainly researched in Yangshan Area of Haikou City. The results showed that resisting wind and holding moisture were the key factors for planting Bougainvillea in Yangshan Area. These two varieties has a capability of drought resistance and heat tolerance in Hainan Region in summer,they were easy to be dead when effective accumulated temperature was too high. It can safely through the winter in open-field cultivation,and damaged situations primarily appeared in leaves. Meanwhile,our research found that potted experiments in the soil could promote its flower bud differentiation and induce blossom.
