| 摘 要： | 通过5个含磷质量分数不同的底质内菹草的生长试验,研究了水体底质中含磷质量分数的单因子差异对菹草生长的影响.结果表明,含磷质量分数≤2.0 g/kg的底质中菹草在试验期间均正常生长,含磷质量分数的增加对菹草生物量的累积和平均株高的增长起促进作用；当底质中含磷质量分数达到2.5 g/kg,从试验中期(21 d)开始,菹草正...

| Abstract: | In a growth experiment,five substrates with different concentrations of phosphorus were installed to determine the effects of phosphorus in sediments on Potamogeton crispus.Results showed that during the experiment,the plants vegetated naturally when the concentration of phosphorus in substrates was less than or equal to 2.0g/kg,the biomass and the mean length of plants increased with increasing concentration of phosphorus.When the concentration of phosphorus was 2.5g/ kg,the stress of phosphorus on growth ... |
