| 摘 要： | 研究了人工湿地污水处理系统中的菩提子（Coixlacryma-jobi Linn.）生长及其对氮、磷的吸收动态,并探讨了收割对富营养化水体中氮、磷吸收作用的影响。结果表明：在夏秋季节,特别在8月,菩提子可获得较高的生物量和氮、磷累积量,因而净化贡献最大;从植物体饲用价值看,适当增加收割次数可使菩提子中氮、磷含量高,但收割次数过多,并不利于菩提子对污水的净化及氮、磷的积累。综合考虑,在菩提子整个生长期,应在8月进行全面收割,收割次数以2～3次为宜。

| Abstract: | The dynamic of growth and nutrient(N and P) absorption of Coix lacryma-jobi Linn.in constructed wetland(CW),as well as the effect of constructed wetland harvest on N,P absorption in eutrophic water were studied.The results revealed that,in Summer and Autumn,especially in August,C.lacryma-jobi could obtain higher biomass and N,P accumulations,thereby achieving the most efficient purification;from the breeding value point of view,N,P contents could be improved by the appropriate increase of harvest times of C.lacryma-jobi,while too many harvest times was inappropriate to the wastewater purification by C.lacryma-jobi and the nutrients accumulation.So,C.lacryma-jobi should be harvested completely in August during its growth period,and 2-3 times of harvests was appropriate. |
