摘　　要：以水生植物雨久花为试材,在含有不同浓度的酚、氨氮的营养液中培养,研究了雨久花地上部分、地下部分的生长和其对酚、氨氮的抗性及吸收积累规律。结果表明:雨久花能够在含有一定浓度酚、氨氮的污水中正常生长,并且对酚和氨氮的去除力也比较可观,平均去除率分别为85.2%和73.1%;同时雨久花地上部分、地下部分对酚的富集系数最大,分别达到9.58和4.64,其对氮的积累量分别高达712.682和498.815mg/株。可见雨久花能够去除水中的酚和氨氮,对净化水质具有良好的作用。：Taking aquatic plants Moiuchoria korsakowii as materials, under the conditions of the nutrient solution containing,different concentrations of phenol and ammonia nitrogen on the growth of Monochoria korsakowii of the ground part and the underground part, and Monochoria korsakowii resistance uptake and accumulation of organic pollutants in water phenol and ammonia nitrogen were studied. The results showed that Monochoria korsakowii could grow in the sewage contains a certain concentration of phenol and ammonia nitrogen, and removal force of phenol and ammonia nitrogen was more considerable, the average removal rates respectively was 85. 2% and 73. 1%; while the enrichment coefficient for phenol of Monochoria korsakowii of the ground parts of the underground part respectively reached 9. 58 and 4. 64,the largest accumulation of its nitrogen were 712. 682 mg and 498. 815 mg per plant. It showed Monochoria korsakowii could remove the phenol and ammonia nitrogen in the ,waste water and played a good role for purifying water.
