摘　　要：通过水面浮床栽培试验,研究了雪里蕻植株的生长特性,及其对富营养化水体中氮、磷物质的吸收能力。结果表明:浮床雪里蕻植株的平均鲜量30 g,平均株高15 cm,平均根系长35 cm,其对氮、磷的直接吸收量分别达到67.3 kg/hm2和4.8 kg/hm2。雪里蕻能够在水中安全越冬并完成整个生育周期,对富营养化水体也具有一定的净化效果,可作为冬季富营养化水体治理的一种浮床栽培植物。Experiments on potherb mustard planted on floating-bed were performed to study the growth characteristic of potherb mustard and its capacity of absorbing Nitrogen and Phosphorus from eutrophic water body.Results showed that the potherb mustard on floating-bed had a fresh weight of 30 g,culm height of 15cm and root length of 35 cm on average per plant.The amount of directly absorbed Nitrogen and Phosphorus amounted to 67.3 kg/hm2 and 4.8 kg/hm2 respectively.The results suggested that potherb mustard could grow well throughout the winter and was effective for eutrophic water purification.It is a new and alternative approach for the treatment of eutrophic water body in winter.
