摘　　要：现代农业生产中化肥的大量应用带来了资源破坏、环境恶化等系列问题。稻田综合种养模式利用生物的互惠功能,大大减少了化肥等资源的使用。本文综述了我国主要稻田综合种养模式的化肥减量效应,从增加稻田有效养分、促进水稻养分吸收、减少稻田养分损失、减少其他生物取食等方面分析了其作用机理,并提出应加强对稻田综合种养碳氮循环、有机种植模式、稻米品质影响、专用品种筛选与培育等方面的研究,促进稻田绿色高效技术模式的发展。The continuous and heavy application of chemical fertilizers in modern agriculture has brought about a series of problems,such as resource destruction,environmental deterioration and so on.The rice-based co-culture system is a successful case in utilizing facilitation between co-cultured species to reduce chemical fertilizers.This paper reviewed the fertilizer reduction effects on representative rice-based co-culture system in China,analyzed the mechanisms from the aspects of increasing the available nutrients in rice field,promoting the nutrient absorption of rice,reducing the nutrient loss in rice field and reducing the feeding of other organisms.It is suggested that further studies should be strengthened on carbon and nitrogen cycle,organic planting pattern,rice quality,special variety selection and cultivation to promote the development of green and efficient technology model.
