18个高山杜鹃品种在滇中地区的生长适应性
|
摘要
【目的】为筛选出适合于滇中地区种植的高山杜鹃品种。【方法】对引进种植5年的18个高山杜鹃品种植株高度、冠幅、分枝数、当年生枝叶簇宽度、当年生枝长度和粗度、当年生枝叶片数量及开花情况进行观测。【结果】18个引进品种的株高、冠幅和分枝长势均较好,长势最好的品种是English Roseum,株高达110 cm,冠幅达123.3 cm,分枝达86个,并且其增长量显著高于其他品种;植株当年枝长度和粗度、当年生枝叶片数、当年生枝叶簇宽度的生长表现大多数都较好,只有Blue Peter、Jun Ifeuer、Brigitte和Blue Peter等少数品种增长较为缓慢;在开花的11个品种中, Halfdanlem、Blue Peter、English Roseum等品种的开花性状表现较好。【结论】高山杜鹃适合在滇中地区栽植,其中栽植效果较好的品种是English Roseum、Halfdanlem和Jun Ifeuer。
【Objective】This paper aimed to select the suitable R. lapponicum cultivars in the Central Yunnan region. 【Method】The plant height and width, the branches' numbers, the foliage length and width in the branch and the truss characteristics of 18 R. lapponicum imported cultivars were investigated in 2018, which were introduced from Belgium to Yunnan in 2013.【Result】18 Rhododendron cultivars had grown well and R. ‘English Roseum' had the best growth with 110 cm of plant height, 123.3 cm of plant height, and 86 of branches. The foliage length and width in the branch increased quickly for the tested cultivars except R. ‘Blue Peter', R. ‘Jun Ifeuer', R. ‘Brigitte' and R. ‘Blue Peter', which just had a slow increase in growth. R. ‘Halfdan Lem', R. ‘Blue Peter' and R. ‘English Roseum' had the better inflorescence characteristics among the 11 flowering Rhododendron cultivars. 【Conclusion】R. ‘English Roseum', R. ‘Halfdan Lem', and R. ‘Jun Ifeuer'the best R. lapponicum cultivars were more suitable for planting in the Central Yunnan region, which were the suitable area for planting Rhododendron.
