- Abstract
Field experiment was conducted to investigate the effects of rice-duck farming on the water environment in paddy field. The results showed that under rice-duck farming, the temperature and pH value of the surface water in paddy field decreased, and the electrical conductivity, oxidation-reduction potential, turbidity, and the contents of nitrogen (N), phosphorus (P) and potassium (K) increased. The total N, P, and K increased by 1.85-5.06 times, 2.01-8.70 times, and 42.79%-109.18%, respectively, as compared to those in conventional rice farming. All of these illustrated that rice-duck farming improved the paddy field water environment and nutrient supply, optimized the ecological environment of paddy field, and promoted the growth and development of rice.
