Water hyacinth is Eichhornia crassipes, whose scientific name is Eichharnia crassipes. It belongs to the Eichhorniaceae family and the genus Eichhornia crassipes. In 1901, Eichhornia crassipes was introduced to China as an ornamental plant. In the 1950s and 1960s, it was promoted as pig feed. After that, Eichhornia crassipes grew out of control in China. Water hyacinth is mainly distributed in southern China. Due to the freezing period of rivers in the north, water hyacinth cannot survive in the natural state. Eichhornia crassipes adopts a brutal blockade strategy on the water surface where it lives, blocking sunlight, causing underwater plants to die due to insufficient light, destroying the food chain of underwater animals, and causing the death of aquatic animals. At the same time, ships of any size cannot come and go freely in the territory of water hyacinth. Not only that, Eichhornia crassipes also has the ability to enrich heavy metals. After Eichhornia crassipes dies, its decaying body sinks to the bottom of the water to form a layer with high levels of heavy metals, directly killing benthic organisms. It can be described as a trinity of extermination tactics! In the south, water hyacinths have become overrun. For example, the Pearl River water system is now covered with water hyacinths (according to statistics, the number of water hyacinths in the Pearl River system increases tenfold every ten years!). Water hyacinth is the young leaves and petioles of Eichhornacrassipes (Mart.) solms, also known as water hyacinth. Fresh water hyacinth contains 95.2 grams of water per 100 grams, 1.1 grams of protein, 0.7 grams of fat, 1.4 grams of fiber, 30 mg of calcium, 80 mg of phosphorus, and a variety of vitamins. Water hyacinth has the effects of clearing away heat, detoxifying, dehumidifying, and dispelling wind and heat.
