grown by water spinach. Meanwhile, the purification effect of this
aquatic economic crop floating bed was analyzed and the removal
mechanism of nitrogen and phosphorus was clarified. In addition,
a sustainable way of the ecological agriculture park was designed,
which could provide a favorable guidance and case study for the
