中文摘要:
      通过构建虎杖浮床对其净水能力进行研究,通过高效液相测定土生、水生长虎杖根、叶中虎杖苷含量。结果显示水生虎杖生长状况良好,粗壮浮床根越冬后第二年能正常发芽,在一定时间段内可持续使用;3.5%(虎杖重/水体重)虎杖20 d对养殖水体中TN、TP、NO3--N、NH4+-N去除率分别达到69.4%、71.3%、90.3%、74.1%,虎杖对污水各污染指标中NO3--N的吸收能力最强,其次是TN、TP、NH4+-N、NO2--N。土生虎杖根虎杖苷含量约为水中根的10倍,土生叶中虎杖苷含量比水生叶高出约50%。
英文摘要:
      Floating bed ofPolygonum cuspidatum was constructed, the polydatin content ofP. cuspidatum in the sediment and water were measured by HPLC. The results showed thatP. cuspidatum grew normally in water, and the vigorous root inside floating bed could sprout naturally after overwintering, and could be continuously used for a certain time; the removal rate of TN, TP, NO3--N and NH4+-N of 3.5%P. cuspidatum (the total weight of P. cuspidatum /water) detected on the 20th day was 69.4% , 71.3% , 90.3% and 74.1% , respectively. P. cuspidatum had the highest removal rate of NO3--N among water-quality indexes, then was TN, TP, NH4 +-N and NO2--N. The content of polydatin in soil-growing roots was about 10 times as that in water-growing roots. The content of polydatin in soil-growing leaves was about 50% higher than that in water-growing leaves.
