中、美、德等多國(guó)學(xué)者進(jìn)行的一項(xiàng)農(nóng)業(yè)環(huán)境研究創(chuàng)新性地提出一條農(nóng)業(yè)減碳技術(shù)路線。通過(guò)對(duì)現(xiàn)有減碳方法的優(yōu)化,我國(guó)糧食生產(chǎn)有望實(shí)現(xiàn)碳中和。
Chinese scientists, in collaboration with researchers from the United States and Germany, have proposed an agricultural carbon reduction solution that could help China achieve carbon neutrality in its food production, according to the Institute of Soil Science under the Chinese Academy of Sciences (CAS).
中科院南京土壤研究所近日稱,中、美、德等多國(guó)學(xué)者提出一條農(nóng)業(yè)減碳技術(shù)路線,我國(guó)糧食生產(chǎn)有望實(shí)現(xiàn)碳中和。
According to the research model evaluation, the total carbon emissions from the production of China's staple crops, including rice, wheat and corn, could have neared 670 teragrams of CO2-equivalent in 2018.
根據(jù)研究模型測(cè)算,2018年我國(guó)生產(chǎn)三種主糧作物(大米、小麥和玉米)產(chǎn)生的碳排放總量可能達(dá)到6.7億噸二氧化碳當(dāng)量。
Completing a comprehensive life-cycle assessment using data from China, the research team showed that an integrated biomass pyrolysis and electricity generation system coupled with commonly applied methane and nitrogen mitigation measures can help reduce staple crops' annual life-cycle greenhouse gas emissions from 666.5 now to minus 37.9 teragrams of CO2-equivalent.
研究小組利用中國(guó)的數(shù)據(jù)完成了一項(xiàng)綜合生命周期評(píng)估,結(jié)果表明,將生物質(zhì)熱解和發(fā)電系統(tǒng)相結(jié)合,再加上常用的甲烷和氮肥優(yōu)化管理,可以幫助將主要作物的年生命周期溫室氣體排放量從現(xiàn)在的666.5太克二氧化碳當(dāng)量減少到負(fù)37.9太克。
"This new path can help achieve carbon neutrality in grain production without sacrificing grain output. It can also reduce atmospheric pollution emissions, increase the utilization rate of fertilizer resources, and increase both environmental and economic benefits by more than 30 percent," said Yan Xiaoyuan, the lead scientist from the CAS Institute of Soil Science.
領(lǐng)導(dǎo)此項(xiàng)研究的中科院南京土壤研究所研究員顏曉元介紹說(shuō):“這一新的技術(shù)路徑可以在不損失產(chǎn)量的前提下幫助實(shí)現(xiàn)糧食生產(chǎn)碳中和,同時(shí)減少大氣污染排放,提高化肥資源的利用率,將環(huán)境和經(jīng)濟(jì)效益提高30%以上?!?/p>
The study was led by the CAS Institute of Soil Science in partnership with several other research institutes, including the China Agricultural University, Tsinghua University, and Cornell University. The research findings were published online in Nature Food on Feb. 9.
這項(xiàng)研究由中科院南京土壤研究所、中國(guó)農(nóng)業(yè)大學(xué)、清華大學(xué)、康奈爾大學(xué)等多家權(quán)威研究單位共同完成。相關(guān)成果于2月9日刊發(fā)在知名學(xué)術(shù)刊物《自然·食品》網(wǎng)絡(luò)版上。
