一、水葫芦的生物学特征特性及其功用 水葫芦学名凤眼莲,又名水泡莲,为多年生漂浮性宿根水生草本植物。根系发达茂密,附着绒毛,悬垂水中,有很强的吸附和分离毒物毒素的功能。据国外研究,一公顷水葫芦,一昼夜内可从水中吸附氮44公斤、磷17公斤、钾45公斤、钙22公斤、钠30公斤、镁4公斤、锰4公斤。对有毒物质汞、铅、镍、钴、锶、镉、金、银、硒和酚等,可吸附0.18～2.2公斤。试验证明,在24小
First, the biological characteristics of water hyacinth and its function Water hyacinth, Eichhornia crassipes, also known as water lotus, perennial floating perennial aquatic herbaceous plants. Roots developed dense, attached to fluff, suspended in water, there is a strong adsorption and separation of toxic toxins. According to foreign studies, one hectare of water hyacinth can adsorb 44 kilograms of nitrogen, 17 kilograms of phosphorus, 45 kilograms of potassium, 22 kilograms of calcium, 30 kilograms of sodium, 4 kilograms of magnesium, and 4 kilograms of manganese from the water within a day and night. The toxic substances mercury, lead, nickel, cobalt, strontium, cadmium, gold, silver, selenium and phenol, can absorb 0.18 to 2.2 kg. Test proved that at 24 hours
