Control water hyacinth

There are three ways to inhibit the growth of water hyacinth. First, introduce the natural enemies of water hyacinth. They feed on water hyacinth and can inhibit the growth of water hyacinth. Second, reduce the nutrition in the water. Nowadays, water hyacinths are all caused by eutrophication. If the water quality is good, the water hyacinth will not grow wildly and will eventually be rejected by local species. The third is manual salvage.

At present, there is no good method to control water hyacinth. Personally, I think there is another way, because water hyacinth can't survive the winter when the water temperature is lower than 10 degrees, so the infection of water hyacinth occurs in the south. After Anhui, there will be no distribution of water hyacinth, let alone its overgrowth. However, the water hyacinth rots in the water body after overgrowth, and the heat generated can keep some nutrients overwintering, and it will overgrow again when the water temperature rises next year, so this method remains to be seen.
