To talk about the scourge of invasive species, the more dramatic ones are the silk seeds and water hyacinths. As early as a decade ago, the major waters of the mainland suffered from the invasion of water hyacinths, flooding everywhere, which not only affected the navigation of the river, but also destroyed the circulation of the water ecosystem, and the native species were excluded and became endangered species. As we all know, how terrible is the harm of this water hyacinth? However, Cambodia regards it as a treasure, not only is it not afraid of its invasion, but it is even prepared to plant a large number of plants. What's going on here? Let's start with the water hyacinth as we know it, which has been classified as a harmful invasive species by many countries, and its invasion of waters in various places will cause serious damage to local water ecosystems.
Water hyacinth is essentially a water weed, unremarkable, it is native to the Amazon region, somehow brought to the world, has become a serious invasive species. The continent is one of the countries where water hyacinth is an invasive species. Water hyacinth looks like a harmless aquatic weed, in fact, its destructive ability can not be imagined at all, water hyacinth has a lot of characteristics, such as the vitality is very tenacious, in the lack of nutrients has been able to maintain a rapid growth rate, its growth rate is very fast, in its suitable for the perfect environment, a water hyacinth can grow 5 meters a day, just like we close our eyes and know that it is growing. The second is that its reproductive ability is very strong, a water hyacinth can produce tens of millions of seeds a year, and the ability to reproduce offspring is super strong. The most frightening thing is that the water hyacinth has a long life cycle, generally surviving for decades, and if you don't remove it, it will exist for a long time.
Once the water hyacinth enters the new water, it will grow and reproduce wildly, causing devastating damage to local organisms, such as robbing the living space, so that many species can not photosynthesize at all, and eventually rot away, not only the plant is affected by the water hyacinth, the animals below the water ecology will also lose their living space because of the growth of the water hyacinth, and eventually face an existential crisis. In fact, these are only superficial, for the area where the water hyacinth grows, the silt in the river channel and the lake will gradually increase, eventually causing the river to block and the lake to change. No matter from which aspect, water hyacinth is a scourge, and it is naturally reasonable for the mainland to treat it as a scourge.
But why is Cambodia so crazy, others are invasive species, as ecological killers, they regard water hyacinth as a treasure and plan to plant it. What's going on here? It turns out that Cambodia is not stupid, people are just using water hyacinth waste. Cambodians see that the water hyacinth grows so fast, and find that the branches of the water hyacinth are rich in fibers, so they let the water hyacinth flood while salvaging the water hyacinth, and then remove the leaves of the water hyacinth, leaving only the branches, and finally extract the fibers in the branches for economic production.
Today, they have replaced reeds with water hyacinths and successfully commercialized water hyacinths. The advantage of water hyacinth over reeds is that the yield is large, the harvest cannot be completed, and it does not need to be planted manually, and there is no need to worry about no yield. I have to say that Cambodians are more conscious in this regard, turning waste into treasure and turning water hyacinth into a good helper for promoting economic development. For cambodians to deal with water hyacinth, do you think it is eye-opening?
