摘要
通过对沉水植物繁殖方式的归类和分析,揭示了沉水植物繁殖方式的多样性。在总结常见的沉水植物移栽方法的基础上,提出了渐沉式沉床快速移栽技术。研究结果表明:在冬季低温条件下,植物纤维作为生长基质的沉床上菹草和伊乐藻均有一定程度的生长。
Submerged macrophytes, as chief biological parts and important biological environment, play a critical role in the water ecological environment. Various reproduction manners of submerged macrophytes are cataloged and analyzed in this paper. A gradually-submerging bed plantation method is proposed as a new plantation method. It is showed that the gradually-submerging bed made of plant fiber, Potamogeton crispus and Elodea nuttallii can grow in low temperature condition in winter.
