不同种植方式对水生植物生长的影响

水生植物恢复是水体生态恢复与重建的一个关键,而人工快速大面积恢复沉水植物存在较大的难度。在淀山湖318国道近岸水域生态带内,运用水泥涵管覆土种植、箩筐覆土种植、纱布包裹覆土种植、编织袋覆土种植和竹签扦插法对水生植物进行种植。通过实验得出,运用水泥涵管覆土种植的芦苇存活率比用箩筐覆土种植的存活率高;运用水泥涵管覆土+竹签扦插法种植的狐尾藻存活率比其他几种种植方法的存活率高,几种种植方式下的生物量无显著差异。

Effect on Growth of Hydrophyte through Different Planting Pattern

It was hard to recover the aquatic plant through artificial metods in large range although hydrophyte restoration was a key process to recover and rebuild the aquatic ecosystem.The authors used several methods,such as covered soil in cement culvert,covered soil in bamboo crate,gauze encapsulated,woven bags encapsulated and prod cutting plant to plant the hydrophyte in 318 area,Dianshan lake.They found that the survival rate of reed which planted in cement culvert was higher than that planted by bamboo crate...
