Water Purification Function and Cultivation Techniques of Water Caltrop: Research Progress

Water caltrop is an annual aquatic herb and important economic plant, and it is rich in nutrients. The stems and leaves of water caltrop could be used as feed, and the fruit starch content is high which could be used for feed and wine making. In addition, water caltrop could purify the water quality and improve the environment. This article introduced the bio-ecological characteristics of water caltrop, and summarized the research achievements in its function of water purification, germplasm resources, collection and utilization, cultivation techniques, and etc. The study suggested that the research on breeding and matching cultivation techniques of water caltrop should be enhanced to promote the development of water caltrop industry.
