Abstract:
Aquatic plants inhibit algae through nutrient competition, sludge sedimentation and the release of allelochemicals in three ways. Investigating Pistia stratiotes L in East Lake, Shao (2001) observed removal rate of the BOD5 achieved more than 70%; the total nitrogen removal efficiency was 60%, the total phosphorus removal efficiency was approximately 70% or more, and this biochemical inhibitory effect may promote algal settlement. Ho Pool (1999) found that the Rhizoma AcoriGraminei could cause a water total nitrogen (TN) removal rate of 87.4%, a total phosphorus (TP) removal rate of 43.9%, and a dissolved oxygen (DO) increase of 26.6%. These studies suggest that through the promotion of the lake TN and TP, aquatic plants influence bio-deposition into sediments, in addition to their role in the nutrient cycling of lakes. Furthermore, many studies have shown that aquatic macrophytes can produce allelochemicals that could inhibit the growth of algae (Donk & Bund, 2002; A. Gross & Boyd, 1998; Elisabeth M. Gross, 2003; E. M. Gross & Sütfeld, 1994; Mulderij, Smolders, & Van Donk, 2006; Mulderij, Van Nes, & Van Donk, 2007).
