摘　　要：[目的]探讨泊湖沉水植物的移植扩繁效果。[方法]2008～2009年,选择泊湖水深0.5～1.5 m的区域作为移植扩繁优质沉水植物示范区,利用播种和网袋垂挂育苗等方法移植扩繁菹草、轮叶黑藻、苦草等优质沉水植物。[结果]当菹草鳞状石芽播种量为15 000g/hm2时,其扩繁生物量达3 935 g/m2。当轮叶黑藻种芽和苦草种子播种量为3 750 g/hm2时,移植扩繁区沉水植物群落的总生物量为2 573 g/m2,其中轮叶黑藻的平均生物量为1 352.5 g/m2,苦草的平均生物量为631.3 g/m2。[结论]选择优质沉水植物菹草、轮叶黑藻和苦草在泊湖适宜水深移植扩繁效果显著。[ Objective ] The research aimed to discuss the transplantation and propagation effects of submerged plants in Bohu Lake. [ Method ] During 2008 - 2009, the water area of Bohu Lake with water depth of 0.5 - 1.5 m was selected as the demonstration area of transplanting and propagating the submerged plants. Using sowing, mesh bag-hanging seeding method and other method, Potamogeton crispus, Hydrilla verticiUata, Vallisneria natans and other .high-quality submerged plants were transplanted and propagated. [ Result ] When the sowing rate of P. crispus squamous buds was 15 000 g/hm^2, its propagation biomass was 3 935 g/m^2. When the sowing rate of both H. verticillata seed buds and V. natans seeds were 3 750 g/hm^2, the total biomass of the submerged plant communities in the transplantation and propagation area was 2 573 g/m^2. The average biomass of H. verticillata and V. natans was 1 352.5 and 631.3 g/m^2 respectively. [ Conclusion] It had a significant effect to transplant and propagate high-quality submerged plants P. crispus, H. verticillata and V. natans in Bohu Lake in suitable water depth.
