伊乐藻等水生高等植物的快速营养繁殖技术和栽培方法

摘要:
在太湖自然条件下,伊乐藻等7种沉水植物主要靠营养繁殖来延续和扩大种群。在浅水湖泊的生态恢复中,需要在短期内大面积恢复水生植被,营养繁殖与栽培为之提供了有效的手段。在五里湖的实验研究结果表明,伊乐藻、黑藻和金鱼藻的插枝繁殖简单易行,可以大面积操作,种源充足,栽植期长,适合于大规模繁殖和栽培。苦草、微齿眼子菜和马来眼子菜营养繁殖力较差,可以分苗移栽,但效率较低,操作比较困难。苦草地下块茎和马来眼子菜根状茎的采集和栽植更加困难,不宜采用这种繁殖与栽培方式。

Artificial vegetative reproduction and plantation technique for Elodea Nuttallii and six other species of submerged plants

Abstract:
Under natural environmental conditions of Taihu Lake, Elodea Nuttallii and six other species of submerged plant depended mainly on vegetative reproduction to survive and spread their population. In the restoration process of shallow lakes, aquatic macrophyte should be planted on a large scale in a relatively short time, and artificial vegetative reproduction and plantation skill is needed for this purpose. Transplanting the cuttings of Elodea Nuttallii, Hydrilla verticillata and Cerotophyllum demersum was proved to be very easy and effective for sufficient shoot supply, long planting season, and large-scale operation. However, Valiisneria spiralis, Potamogeton maackianus and P. malaianus had low vegetative reproduction capacity As a result, seeding transplantation was still effective although it was difficult and slow. It's more difficult and undesirable to transplant subterraneous tuber of Valiisneria spiralis and stock of Potamogeton maackianus unless it was particularly needed.
