Abstract:
Five kinds of wetland plants such as Arundo donax var.versicolor Stokes,Lythrum salicaria Linn.,Distylium buxifolium (Hance) Merr.var.rotundum H.T.Cheng,Salix integraThunb.‘Hakuro Nishiki’ and Adina rubella Hance were selected for this pot experiment to study their net sewage capacity.The results showed that the body content of nutrient elements of the five kinds of wetland plants had changed after the growth in the sewage.Arundo donax var.versicolor Stokes had a strong ability to absorb Mg,Mn,Zn.The Mg,Fe,Mn had a large increase in the Lythrum salicaria Linn.leaves after sewage treatment.Distylium buxifolium (Hance) Merr.var.rotundum H.T.Cheng had a strong ability to absorb Ca,Fe,Mg,Al,Na while Salix integra Thunb.‘Hakuro Nishiki’ had a strong ability to absorb Al,Adina rubella Hance had a strong ability to absorb N,Fe,Zn,Al.Because the nutrition elements absorption abilities depended on the type of plants,the selection on appropriate artificial wetland green plant species should be based on water quality in engineering practice.
