摘要
对1993—1995年在东太湖边池塘中进行的伊乐藻等几种沉水植物的生物量、生产量测定以及竞争态势试验结果进行了分析,阐明了因收割方法不同,水草的单位面积产量及营养物质量不同;并以中位刈割方法为最佳;在竞争试验的环境条件下伊乐藻是优势种。
The biomass, production and competitive growth of Elodea Nuttallii and other submerged plants was studied in a pond by Taihu Lake side during 1993 - 1995. The study shows that means of harvest affect the production of the submerged plants, cutting its half biomass per time make peak annual output, and Elodea Nuttaliii is dominant species under the environmental condition of experiment.
