摘　　要：为探讨鸭稻共作对水稻某些生理特性的影响,本研究设计了不同的鸭稻共作处理区,研究了鸭子活动对水稻植株的某些生理学特性的影响.结果表明,鸭稻共作能降低叶片的质膜透性、丙二醛含量和脯氨酸含量,提高超氧化物歧化酶、过氧化物酶、过氧化氢酶的活性及可溶性糖含量.说明鸭稻共作方式对提高水稻植株的抗性、延缓叶片衰老以及对水稻的生长发育均具有积极作用.A field experiment with four treatments of flce-duck farming was conducted in the Zengcheng Teaching and Research Base of South China Agricuhural 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 flee growth and development.
