低碳农业技术梳理与体系构建

Review on the Technologies of Low-Carbon Agriculture and Its System and Construction

通过对农业活动中各个生产环节的碳效应进行深入剖析,确定相应环节的碳减排或固碳潜力,并在充分回顾前人研究结果的基础上,对现有的低碳农业技术进行梳理,试图筛选并构建一套低碳农业技术体系,为实现农业活动中各生产环节的低碳发展提供参考。农业生产过程中的碳效应主要来源于耕作、灌溉、施肥、施药、农膜使用、农业机械使用、秸秆处理、畜禽养殖、畜禽粪便处理和林草地保护十个农业生产环节,文章以此构建了低碳耕作技术体系、低碳灌溉技术体系、低碳施肥技术体系、低碳施药技术体系、农膜低碳使用技术体系、秸秆资源化利用技术体系、畜禽低碳养殖技术体系、畜禽粪便低碳处理技术体系和林草地保护技术体系共9个方面的低碳农业技术体系。

Based on various links of agricultural production activities researches in carbon effect, to confirm the corresponding links of carbon emission reduction or carbon sequestration potential. Besides, in full review based on the results of previous studies, this paper mainly sorts the existing low carbon agricultural technology and tries to filter and construct a low carbon agricultural technology system in order to provide reference to realize agricultural activity in each production link of low- carbon development. The effect of carbon in the process of agricultural production mainly comes from the links of agriculatral production, including tillage, irrigation, fertilizer, application of pesticide, the use of plastic film and agricultural machinery, straw treatment, livestock breeding, livestock manure treatment, forest and grassland protection. And then constructing nine aspects of the low-carbon agricultural technologies system on the basis of carbon effect in the process of agricultural production includes low-carbon technology system of tillage, low-carbon technology system of irrigation, low-carbon technology system of fertilization, low-carbon technology system of application of pesticide, low-carbon technology system of the use of plastic film, technology system of utilization of straw resource, technology system of livestock breeding, low-carbon technology system of animal manure treatment, technology system of forest and grassland protection.
