The agroecological team answered in the research how different rice production systems can achieve carbon sequestration and emission reduction

Carbon footprint per unit economic benefit of different rice cropping systems (kg CO2-eq yuan-1)

Nanhu News Network (correspondent Ayitullah Maimat Zunong) Recently, our university’s Macro-Agricultural Research Institute, the agroecology research team of the School of Plant Science and Technology and the Institute of Agricultural Environment and Sustainable Development of the Chinese Academy of Agricultural Sciences have cooperated in research, answering The question of how different rice production systems can achieve carbon sequestration and emission reduction

The study is based on the determination of CH4 and N2O in rice production systems such as rice slack, rice-oil rotation, rice-wheat rotation, double-cropping rice and rice-shrimp co-cultivation by the agro-ecological team at different experimental stations in Hubei Province using a unified static box-gas chromatography method.

The research results show that each rice production system needs to be equipped with different emission reduction measures to achieve high income-low emissions, and the same measures have different emission reduction roles in different models

The research results were published on Science of the Total Environment under the title of "Comparing rice production systems in China: Economic output and carbon footprint".

Corresponding author (Cao Cougui) of the paper, after more than 10 years of research on carbon sequestration and emission reduction in the rice cropping system, put forward the low-carbon rice farming theory of "increasing sinks, reducing consumption, reducing emissions, and recycling", and published the "low-carbon rice farming theory" And Practice" monograph

Reviewer: Cao Cougui, You Liangzhi

【English summary】

In recent years, many rotational and integrated rice production systems coupled with several greenhouse gas (GHG) emissions mitigation practices have been developed and adopted for demand of low carbon production.
