One of the hazards of water hyacinth is that it will lead to ecological destruction because of its strong reproductive ability. If the living environment is suitable for the growth of water hyacinth, it will multiply and become the dominant species, affecting the growth of other organisms. If it continues for a long time, the ecological diversity of this area will be destroyed and its species will be single.
The ecological balance of a region is very important. Only when species interact and inhibit each other can balance be maintained. The crazy growth of water hyacinth will break the balance of this area to a great extent, deprive other creatures of living space and make some species on the verge of extinction.
2, affect the growth of other creatures
When the water hyacinth grows vigorously, it will grow full of water, cover the whole water and dye the water green. At this time, it will affect the gas exchange between water and the atmosphere, as well as the transmission of light, and will increase the concentration of CO2, affecting aquatic organisms.
It will block the river.
Wild water hyacinths can block waterways. Because the plants of water hyacinth multiply in large numbers, the plants are increasing and will soon cover the whole river. In severe cases, the density of water hyacinth growth can even make people walk on it, affecting water transport. In addition, the growth of water hyacinth will even affect the growth of tap water in water plants, because the excessive reproduction of water hyacinth will block the production equipment of tap water.
Extended data
Water hyacinth is native to South America. 1884, the International Cotton Expo was held in New Orleans, USA, and merchants gathered. People saw gourd-shaped green plants floating in the water, and the blue and purple flowers on them were very beautiful, so they took them back to their own countries to breed.
At that time, it was a rare plant raised by dignitaries and royalty. In the photos left by Empress Dowager Cixi, you can see the figure of water hyacinth. After 100 years, this plant has spread all over the world in tropical, subtropical and warm temperate regions, becoming the most common plant in warm waters.
190 1 was introduced into China as a flower, and was widely used as pig feed in the Yangtze River valley and its south area in 1950s and 1960s, widely distributed in South China, Central China and East China, especially in Yunnan, Sichuan, Hunan, Hubei, Jiangxi, Jiangsu, Zhejiang, Fujian and Taiwan Province provinces.
