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.
