枫杨幼苗对富营养化水体中总氮总磷的去除效果
Removal effect on total nitrogen and total phosphorus in eutrophic water of Pterocarya stenoptera
摘要
Abstract
This paper investigated the morphologic changes and the uptake effect on TN and TP in eutrophic water by using one-year seedlings of Pterocarya stenoptera, which were planted in 4 treatments of simulated eutrophic water with various concentration of TN as 2. 0,30. 0,40. 0, 80. 0 mg/L and TP as 0. 4,8. 0,15. 0,25. 0 mg/L respectively from September to November, 2009. Results showed that P. Stenoptera had rather strong adaptability to the eutrophic water, and they grew well in it, with height, stem base diameter, leaves number increase more or less. P. Stenoptera demonstrated a good removal effect on TN and TP of 4 different concentrations, with the average uptake rates 8. 31 % and 23. 79 % , among which the best uptake capacity for TN, TP appeared when they were in the lowest concentration, reached 17. 06 % and 40. 86% on average. All the results indicated that P. Stenoptera was an applicable wetland regional tree species in the eutrophic water.关键词
