Pistia stratiotes

Experiment Research in Purification on Nutrient Lakes by means of Pistia Stratiotes

水浮莲净化富营养化湖泊试验研究

Daily ration of apple snails with 1.06 ± 0.09g/per snail fed with alligator weed and Pistia stratiotes was 17.37 ± 0.73%, 22.30 ± 0.84% respectively;

结果表明，每只体重1.06±0.09g福寿螺对水花生和水浮莲的摄食率分别为17.37±0.73%、22.30±0.84%；

A survey of the water plants carrying metacercariae of Fasciolopsis buski at 102 ponds shows that on average, each plant of the Pistia stratiotes carries 5.09 metacercariae, and every 500 gins.

总共调查102个疫区有代表性的种植水生植物的池塘，检查各种水生植物对姜片虫囊蚴的感染率，其中水浮莲的检出率为23.5%，平均每个水浮莲携带有5.09个囊蚴。
