In China, there is such an aquatic plant, whether it is the Yellow River, the Yangtze River, the Pearl River, or lakes, ponds, small puddles, as long as there is water, it can often be seen. It has blue flowers and looks good. It was originally an ornamental plant in South America. Later, it was praised as the "lavender Corolla to beautify the world" at foreign exhibitions. Then it was introduced into various countries, and China also introduced it. But no one knew at that time that it would become "one of the world's top 100 invasive species", and now they all regret it.

This kind of aquatic plant has a well-known name in our country, called "water hyacinth". I believe many people have seen it. In fact, its scientific name is "Phoenix Eye Blue", because there is a piece of purple in the middle of its flowers, which looks like Phoenix Eye and looks very beautiful. It was first introduced as a flower. Phoenix blue originated from Brazil in South America, and it was restricted by natural enemies in Brazil, but after entering other countries, it lost its natural enemies, began the road of frenzied breeding, and became the "number one public enemy" of agriculture, water conservancy, and environmental protection in all countries.

The viability of Phoenix eye blue is very strong, it can grow not only in clear water, but also in domestic wastewater and industrial sewage. It was once used to purify the water environment, but its reproductive ability is too strong. After entering a certain water area, it will quickly become a dominant species, "go its own way, so that others have nowhere to go." the waters invaded by it cannot even survive many plankton. The water surface is all covered, there is no oxygen in the water, and there is no photosynthesis. A large number of fish will die, and eventually the whole area of water will turn green and stink.

And Phoenix blue can settle down everywhere with the current, seriously blocking river waterways, some of which grow so thick that they can even withstand people walking on it, resulting in the paralysis of river shipping. In addition, Phoenix blue is also seriously harmful to the waterworks, which will not only lead to poor water quality, but also lead to blockage of the filter tank and water stoppage once the pump is inhaled.

However, Phoenix blue is not useless, at least in our rural areas, it has many uses, not only can raise fish, but also feed chickens and ducks, pigs and so on, many farmers can not do without it.

Phoenix blue contains a variety of trace elements, but also contains a variety of crude protein, crude fat and fiber, it is crushed or beaten into pulp, mixed into a variety of wheat bran feed, has become a feed for poultry and livestock, was once a very popular pig feed in the grandparents' time. The tender stems and leaves of Phoenix Eye Blue is also a delicious wild vegetable, tender and juicy, with the effect of heat-clearing and detoxification, moistening and defecating, but pay attention to the choice of Phoenix Eye Blue in clean waters. Readers, have you ever eaten Phoenix Eye Blue?
