总结了南方集约多熟农区稻田耕作制度的发展和演变过程,分析了南方集约多熟稻田保护性耕作制的技术特征、模式和研究进展。认为中国南方稻区已形成一系列突破性保护性耕作关键技术,并取得了显著的生态、经济和社会效益,为南方集约多熟稻区的粮食生产和生态环境保护提供了有益的途径;指出了研究和推广中存在的不足,提出在今后南方集约多熟稻区保护性耕作的发展过程中,要继续加强区域布局、技术机理和生态经济评价方面的研究,进一步规范模式和技术集成,为制定保护性耕作技术生态补偿政策提供科学依据。
The development and evolution of paddy field farming system in intensive agricultural areas in southern China were summarized. The technical characteristics, patterns and research progress of conservation tillage systems in southern intensive multi-cropping paddy fields were analyzed. It is believed that a series of breakthrough key technologies of conservation tillage have been formed in the rice paddies in southern China and significant ecological, economic and social benefits have been achieved, which provide a useful approach for food production and ecological environment protection in intensive southern rice paddies In the process of the development of conservation tillage in the intensive and multi-cooked rice area in the future, we should continue to strengthen the research on the regional layout, technical mechanism and eco-economic evaluation, and further standardize the mode and technology integration for Provide scientific basis for developing ecological compensation policy of conservation tillage technology.
