挑选51种草本多肉植物,其中景天科12个属、番杏科2个属、马齿苋科1个属、唇形科1个属,针对贵州石漠化山地生态特征对以上种属品种进行越冬适应性评价。结果表明:大部分冬型种多肉植物能较好的适应冬季的低温天气,除了‘新玉缀’(Sedum burrito)、‘千佛手’(Sedum sediforme)生长受低温影响导致生长不良,出现植株死亡;而部分夏型种、春秋型种通过休眠方式也能安全越过冬季。筛选出30种多肉植物品种,其中景天科11个属、番杏科1个属、马齿苋科1个属,在贵阳石漠化山地生长良好且能安全越冬,为多肉植物的园艺生产和在贵阳石漠化山地上的园林应用等实践工作提供基础数据。
51 herbaceous succulents were selected, of which 12 genera were Sedum, 2 genera of Ampelopsis, 1 genus of Portulaca oleracea and 1 genus of Labiatae. According to the ecological characteristics of rocky desertification in Guizhou, Overwintering adaptability evaluation. The results showed that most of the winter-type succulents could adapt well to the cold weather in winter, except for the growth of ’Sedum burrito’ and ’Sedum sediforme’ And some summer type, spring and autumn type through sleep mode can safely cross the winter. Thirty species of succulent plants were screened out, of which 11 genera were Sedum, 1 genus Apecaceae and 1 genus Portulaca oleracea were grown well in Guiyang, And the application of landscaping in rocky mountainous areas of Guiyang and other practical work to provide basic data.
