稻鸭共作系统的生态学效应研究进展

Review on the Ecological Effects of Integrated Rice-duck Farming System

稻鸭共作技术作为一项环保型的生态农业技术,现已在中国多个省份和其他许多亚洲国家中得到应用和推广。稻鸭共作系统中具有很多的生态学效应。对该系统中鸭子活动对水稻植株产量性状、群体结构、稻田杂草、水稻病虫害与天敌、稻田土壤、稻田水体、稻米品质、稻田环境质量的影响效应等方面的研究进展进行了综述,并指出今后应加强对上述生态学效应的内在机理与生态学过程等方面的深入研究,以便更好地服务于实践。

Integrated rice-duck farming system (IRFS), as an environmental friendly technology, has been applied and practiced in many provinces in China and some countries in Asia. There are various ecological effects to be proved in IRFS. This paper reviewed already-done studies on the ecological effects of ducks on rice canopy structure, rice growth and yield formation, control of weeds, pests and diseases, natural enemy population, paddy soil and water, rice quality and paddy environmental quality. This paper also pointed out that some further studies on ecological process and mechanisms in IRFS should be strengthened.
