Cambodian women are very flexible in handicrafts. They use the rhizomes of these plants to weave various handcrafts, such as cup cushions, backpacks, blankets or seat cushions, which can then be used To make money, many foreign tourists to Cambodia also like to buy this kind of handicrafts. As long as there are too many water hyacinths in our country, it will damage the ecological environment, and Cambodians can use the underground stems of water hyacinth to make various handicrafts. Water hyacinth

After escaping to the countryside, water hyacinth showed strong growth and development; they can reproduce both sexually and asexually. In particular, the asexual reproduction rate is very fast, and their stolons can grow into new plants after being separated from the mother plant. It is reported that a single water hyacinth plant can produce 4,000 new individuals in a month under suitable conditions. And new individuals can continue to reproduce asexually, causing a chain reaction. Before long, the surface of a sea area was densely covered with algae.

With strong survivability and fecundity, algae have now spread all over North my country, East China, Central China, South China and Southwest China, and they are present in 19 provinces in total. Algae can be seen everywhere and pollutes the environment greatly. Their root systems are well developed and can completely block the surface of the river and block the sun. The water quality is not exposed to sunlight and becomes more and more smelly; the amount of dissolved oxygen in the water quality is therefore reduced, inhibiting the growth of zooplankton and damaging the ecological environment.

At the same time, a large number of water hyacinths float on the water, blocking the flow of water quality products, allowing pollutants to accumulate, and destroying water bodies; moreover, an outbreak of water hyacinths will also consume a lot of O2 in the water, which is harmful to fish species. have an impact, even causing their death. Because of its great harm, algae is listed as one of the top 100 invasive alien species in the world. From Cambodia, water hyacinth is the "secret" for many farmers to get rich. Cambodians have found their advantage in algae, which is the underground stems.

When the water hyacinth was perfected, Cambodians rowed boats to harvest the seeds. Fish them out and remove the leaves and flowers, leaving only an underground stem about fifty or sixty centimeters long. The harvested algae underground stems do not need any special treatment. They just need to be laid flat and dried for more than half a month. After more than half a month, the water in the underground stems of water hyacinth is dried, and the bright green underground stems turn into dark brown. They are firm and somewhat malleable, making them a good raw material for writing.

Invasive species occur in many countries. For example, crucian carp in the United States, wild rabbits in Australia, dragonets in Japan, etc. are all headaches for foreigners. They are brain-broken by these over-breeding populations. , after seeing the "end" of algae in China and Myanmar, have you ever felt that eliminating alien species still requires wisdom?
