Study on the release of carbon, nitrogen and phosphorus from the decomposition of aquatic plants

Abstract

It is important to study the decomposition process and nutrient dynamics of aquatic plants in order to understand the material circulation process of water ecosystem. The decomposition and release of carbon, nitrogen and phosphorus from aquatic plants at different temperatures were studied by indoor plant decomposition simulation test. The results show that temperature has obvious effect on the decomposition process of aquatic weeds. High temperature is obviously beneficial to the release of carbon, nitrogen and phosphorus. With the increase of temperature, the amount of carbon, nitrogen and phosphorus released into the water increased. The decomposition rate decreases with time.
