低碳经济视角下农田管理的技术体系和模式选择

Study on the Choice of the Technology System and Pattern of Farmland Management from the Low-carbon Economy Perspective

为了探讨低碳经济下农田系统有效地管理和利用模式,系统分析了低碳农业的内涵,以及现代工业化农业模式下主流的农田管理模式对碳排放和碳增汇的影响,并以此为依据提出了现代低碳农业的发展应该从4个方面着手和加强农田管理技术体系和模式的创新:(1)构建以生物技术和物理防治为基础的综合病虫害防控技术体系和管理模式;(2)构建以当地生产生活废弃物利用为基础的生物质能源开发利用技术体系和管理模式;(3)构建以种养加结合为基础的循环农业技术体系和管理模式;(4)构建以免(少)耕栽培和(休闲)轮作为基础的地力培养技术体系和管理模式。

In order to discuss the effective use and management modes of farmland system under the low-carbon economy underground. This paper analyzed sysmetically the influence of main farmland management patterns on the carbon emissions and carbon sinks, it put forward that modern low-carbon agrieuhure should be innovated from the following four aspects： （1） to construct the Integrated technology system and management mode of pest prevention and control based on the basis of biological technology and physical meatures; （2） to construct the technology system and management mode of development and utilization of biomass energy based of the local production and living waste utilizing; （3） to construct technology system and management mode of circular agriculture based on combining the planting, breeding with processing; （4） to construct the technology system and management mode of soil nutrient improvement based on the ＂no/ less-till＂ cultivation and crop rotation.
