- 摘要:
- 以红叶小檗、水蜡、金叶女贞、连翘、北京丁香、小叶黄杨6种常见园林树种为试材，正常光照为对照，测定分析不同程度的遮荫方式对每种树种的苗高、新梢生长情况、叶绿素、叶片含水量、叶面积等生长生理指标的影响。结果表明：不同的园林树木在遮荫环境下生长和生理反应各不相同，其中在无遮荫条件下红叶小檗、小叶黄杨、北京丁香、金叶女贞的各项生长指标最高，水蜡在双层遮荫条件下生长指标最高，连翘的生长指标遮荫组和对照组无明显差异。遮荫条件对连翘、水蜡的生理指标无显著影响，红叶小檗、小叶黄杨、金叶女贞在遮荫条件下生理指标相比对照组较为显著，北京丁香的生理指标单层遮荫组相比对照组显著，双层遮荫组不显著。
- Abstract:
- With Berberis thunbergii cv. atropurpurea，Ligustrum obtusifolium，Ligustrum vicaryi，Forsythia suspensa，Syringga pekinensis，Buxus microphylla as materials,under different shade conditions，the seedling hight，shoot growth,chlorophyll，water content of leaves,leaf area etc were meatured.The results showed that the growth and physiologist of tree specvies under shade were different.The growth index of Berberis thunbergii cv.atropurpurea，Buxus microphylla，Syringga pekinensis，Ligustrum vicaryi were the highest in the open condition，the growth index of ligustrum obtusifolium were the highest in double shade conditions,there was no significant difference between CK and shade conditions to Forsythia suspensa.Shade condition had no significant inflouence on Forsythia suspensa and Ligustrum obtusifolium.The physiologic indexes of Berberis chunbergii cv.atropurpurea,Buxus microphyla and Ligustrum vicaryi had no significant difference between CK. The physiologic indexes of Syringg a pekinensis had significant difference between single shade to CK,and had no significant difference to double shade.
