摘要：研究了聚天冬氨酸(PASP)对香根草生长情况及吸收水体中氮、磷营养物质的影响。结果表明:PASP在一定程度上能够促进香根草的生长,当PASP浓度为10 mg/L时,香根草的株高和鲜质量可分别增长51.3%和4.60%;PASP的存在能增加香根草叶片中的叶绿素含量,当PASP浓度为5 mg/L时,叶绿素a和总叶绿素含量可分别增长43.4%和36.5%;添加高浓度的PASP可提高香根草对水体中NH4+-N、NO3--N和TN的去除效果;PASP对香根草去除TP的促进作用较为明显,当PASP为1 mg/L时,对TP的去除率可达到83.8%,明显高于对照组(46.9%)。
The effect of polyaspartic acid （PASP） on Vetiveria zizanioides growth and absorption of N and P nutrients was investigated. The results showed that PASP could promote the growth of Vetiveria zizanioides. When the concentration of PASP was 10 mg/L, the height and fresh weight （FW） of the plant were increased by 51.3% and 4.60% respectively. PASP could increase the content of chlorophyll in the plant leaf. When the concentration of PASP was 5 mg/L, the contents of chlorophyll a and total chlorophyll were increased by 43.4% and 36.5% respectively. The higher concentration of PASP could improve the removal efficiencies of NHf - N, NO3- - N and TN in water by the plant. The removal of TP was remarkably enhanced by PASP. When PASP concentration was 1 mg/L, the removal rate of TP was 83.8%, which was significantly higher than in the control group （46.9%）.
