１９９１～１９９３年在无锡市马山自来水厂太湖水源区开展的旨在除去藻类和净化水质的物理生态工程实验结果表明，在常有大风浪的太湖开阔水域凤眼莲能正常生长繁殖，夏季的净生产力达５００ｇ／ｍ￣２／ｄ左右。根据实验所得，探讨了在该湖开阔水域放养凤眼莲的技术，研究了凤眼莲在不同时期、不同密度下的生产力、增长率、适宜放养密度等，提出了对凤眼莲生长的计算方法。在此基础上，对比分析了凤眼莲在太湖与内塘生长的个体生物学特性之差异及其原因
From 1991 to 1993, the physical and ecological engineering experiments aimed at removing algae and purifying water in the water source area of Taihu Lake in Mashan Waterworks Wuxi City showed that Eichhornia crassipes can grow normally in the open water of Taihu Lake, Net productivity of 500g / m ~ 2 / d or so. Based on the experimental results, the technique of stocking Eichhornia crassipes in the open waters of the lake was discussed, and the productivity, growth rate and appropriate stocking density of Eichhornia crassipes were studied at different periods and densities. method. On this basis, the differences and the reasons of the individual biological characteristics of Eichhornia crassipes grown in Taihu and Neitang
