[Effects of rice-duck farming system on physiological characters of rice].
A field experiment with four treatments of rice-duck farming was conducted in the Zengcheng Teaching and Research Base of South China Agricultural University to further understand the effects of this farming system on the physiological characters of rice. The results showed that rice-duck farming could decrease the plasma membrane permeability and the malondialdehyde and proline contents of rice leaves, but increase their soluble sugar content and superoxide dismutase, peroxidase and catalase activities, indicating that this farming system had positive effects to the improvement of rice plant resistance and the postponement of leaf aging, being of significance on the rice growth and development.
