Study on the Characteristics of Hydrilla Verticillata and Its Landscape Application,A Species of Submerged Plants

Based on the introduction of characteristics and ecological habits as mesophilia,photophilia,and certain ability of cold resistance of Hydrilla verticillata,the main points of its landscape application,especially on the two aspects of its planting and disposing,are discussed in a detailed way.Hydrilla verticillata can be planted in two ways,that is,directly planted into the bottom of the water,or bound with five or six cutting segments and one small piece of stone to sink in the water.On the prospect of disposing,Hydrilla verticillata can be planted together with other submerged plants as well as be planted alone,and also be with ornamental fishes.All these means of disposing would create excellent water landscape effects.Meanwhile the problems in the planting and disposing of Hydrilla verticillata that should be careful with are analyzed with the hope of providing more sufficient and comprehensive basis for the construction of beautiful ecological water landscape.

沉水植物黑藻的特性及其在园林中的应用

在介绍黑藻形态特征以及喜温喜光、稍耐寒生态习性的基础上,探讨了其园林应用要点,特别是建植与配置2个方面内容,其中黑藻具有直接插入水底和将5、6个扦插条与1块小石头捆绑沉入水底2种建植方式;在配置方面,黑藻既能够与其他沉水植物混合种植,又可以单一种植,也可以放养观赏鱼类,这些配置方式都能形成优良的水体景观效果。同时,分析了黑藻的建植与配置中需要注意的一些问题,以期为景观优美的生态水景建设提供更为充分、全面的依据。

贵州沉水植物资源及其园林应用初步研究

通过调查统计贵州省内沉水植物约有31种,隶属于9科,12属,分布在全省大小河流、湿地、湖泊、沟渠等地。目前在园林中应用较广的有水鳖科和眼子菜科部分种类,还有很多优秀种类亟待开发利用。所以研究贵州省内沉水植物资源种类、分布特性及其园林应用和生态应用研究现状,探讨沉水植物园林造景及其营建策略,对沉水植物在水体景观生态设计中的应用提出建设性意见具有重大研究意义。
