摘要/Abstract

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67.3kg/hm²和4.8kg/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。

Abstract: 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/hm²respectively. 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.

Key words: potherb mustard, cultivation on floatingbed, growth characteristic, water purification
