摘要
研究了水葫芦在改良水质中的作用。经过水质测定表明，当平均照度 １３７９Ｌｘ、平均水温１５ ℃时，测得每公斤水葫芦可以从水体中吸收ＰＯ４３－－Ｐ ５．０ ｍｇ／ｄ，吸收ＮＯ２－Ｎ和ＮＨ４＋－ Ｎ ４７． ９ ｍｇ／ｄ；并且在 １５天内消除水体中的 ＮＯ２－－ Ｎ。水葫芦不仅是一种优良的水生植物性饲料、绿肥，而且能有效地改良水质，降低水体污染。
This paper studied the effects of water hyacinth in imp roving the water quality. Based on the analysis of the comparison of the water q uality determination,this paper shows that under the average water temperature o f 15?℃ and average illuminate of 1?379?Lx，1?kg water hyacinth absorbs PO3-4-P 5.0?mg/d and NO-3-N and NH+4-N 47.9?mg/d in average .In 15 days water hyacinth eliminates the NO-2-N from the water in the pond .These indicate that the water hyacinth is very effective in the improvement of the water quality and the reduction of the water pollution.
