Abstract: “Double carbon” has become the key task of Chinas agricultural green development. It is urgent to reduce agricultural greenhouse gas emissions in order to achieve the carbon neutral goal of 2060. This paper reviews the research progress and development trend of agricultural carbon emission in China in recent years, summarizes the research on the six major emission sources of agricultural materials, rice planting, carbon fixation of cultivated land, straw burning, livestock and poultry breeding and agricultural machinery, and publishes the suggestions and prospects for carbon emission reduction of the six major agricultural emission sources. The research shows that there are many empirical analysis on the agricultural carbon emission intensity of the five major agricultural emission sources of agricultural materials, rice planting, straw burning, livestock and poultry breeding and agricultural machinery, and the carbon emission reduction effect is significant, because of the effective regulation of its carbon emissions and the impact of strengthening the purchase subsidy policy. However, there is less empirical analysis on the carbon sequestration of arable land, and the process of carbon emission reduction is slow, mainly due to the greater impact of the subjective factors of farmers, so we should strengthen the publicity and learning of farmers. Although Chinas total agricultural carbon emissions fluctuate up and down, they tend to decline as a whole. In order to achieve green and sustainable development, the government and the whole people need to work together. The implementation of lowcarbon agriculture is conducive to achieving the 2060 carbon neutral goal.
