[目的]选择10种常见野生地被植物,分别进行5种不同程度遮荫处理,并对其进行形态与生理指标测量研究。[方法]设全光照(CK)、遮荫率55%(A)、遮荫率65%(B)、遮荫率75%(C)和遮荫率85%(D)共5个处理,以城市园林绿化常见的耐荫能力强的红花酢酱草作为对照植物。[结果]在不同程度遮荫处理下,多数植物表现出较强的耐荫性,但部分植物在强度遮荫下生长受到抑制;随着遮荫程度的增加,不同植物的不同指标变化情况各异。[结论]活血丹、红纹过路黄表现出最强的耐荫性,而梓木草、三叶萎陵菜耐荫性相对较弱。
[Objective] The research aimed to select 10 kinds of common wild ground cover plants and carry out 5 kinds of shading treatments respectively, and study the morphological and physiological indexes. [Method] With 5 treatments including full light (CK), 55% (A) shade rate, 65% (B) shade rate, 75% (C) shade rate and 85% As the control plant, the common shade-tolerant Caragana that belongs to the urban landscaping was used. [Result] Most of the plants showed shading tolerance under different shading treatments, but the growth of some plants was restrained under the intensity shading. With the increase of shading degree, the changes of different indicators of different plants different. [Conclusion] Huoxue Dan and red line cross-yellowing showed the strongest shade tolerance, while the shade-tolerance of Zixucao and cloverleaves was relatively weak.
