چکیده
Eutrophication often results in the loss of submerged vegetation shallow lakes and turns lake to be a turbid state. Recovery macrophytes is key restoration eutrophic create clear water However, internal loading control was considered as critical process for recovery after external nutrient reduction. Phoslock® (Lanthanum modified bentonite) useful passivation material controlling loadings (release phosphorus from sediments), which applied restore lakes. effects on growth life strategies are less focused so far. In present study, we studied responses morphological characteristics Myriophyllum spicatum addition sediments. Our showed that significantly decreased contents bioavailable forms sediments, such redox-sensitive bound Fe Mn compounds (BD–P), aluminum (Al–P) organic (Org–P). concentration non-bioavailable calcium (Ca–P), increased treatments compared with controls. At end experiments, total biomass, aboveground biomass relative rate (RGR) M. mesocosms contrast, wet root root–shoot ratio, numbers length were higher than indicated suppressed by Phoslock®, thus decreased; however, increase might beneficial inhibition release resuspension sediments ecosystem.
