Abstract

Abstract:

Rice production is the main source of carbon emissions. Liaoning Province is a major production area of high-quality rice in China. Exploring the potential of carbon sequestration and emission reduction in rice fields is very important for achieving carbon peak and carbon neutralization. Following the basic framework and requirements of IPCC, we estimated the potential of carbon sequestration and emission reduction of rice fields in Liaoning Province. The results showed that the methane emission (CO₂-eqv) from rice fields in Liaoning Province was 2.13-3.39 Tg·a^-1, and the direct or indirect N₂O emission (CO₂-eqv) was 0.37-0.40 Tg·a^-1 or 0.08-0.09 Tg·a^-1, respectively. The total carbon emission (CO₂-eqv) of conventional fertilization was 2.61 Tg·a^-1. Optimized fertilization could reduce carbon emission (CO₂-eqv) by 0.03 Tg·a^-1. Organic fertilization and straw returning increased carbon emission (CO₂-eqv) by 0.42 Tg·a^-1 and 1.36 Tg·a^-1, respectively. The carbon emission intensity per unit area and per unit yield of rice field were the highest in straw returning, which were 49.96%-52.68% and 50.30%-52.46% higher than those of conventional fertilization. The carbon emission (CO₂) intensity per unit area of rice field in Liaohe Delta was the highest, which was 5.17-8.08 t·hm^-2·a^-1; the carbon emission (CO₂) intensity of unit yield in southeast area of Liaoning Province was the highest, which was 0.66-1.01 t·t^-1·a^-1. Liaohe Delta rice area had the largest carbon emission (CO₂-eqv) reduction potential, which was 5.50-14.20 million tons per annum. Among nutrients, the carbon emission (CO₂-eqv) reduction from nitrogen fertilizer was the largest, which was 0.18-12.00 million tons of per annum; among fertilization methods, organic-inorganic combined fertilization showed the greatest reduction, which was 3.78-14.2 million tons of per annum. The amounts of carbon sequestration (CO₂-eqv) in soil with organic-inorganic combined fertilization and straw returning were 0.10-0.28 Tg·a^-1 and 0.22-0.65 Tg·a^-1, respectively, and the offset ratios of carbon sequestration to soil by increased carbon emission were 56.68%-82.52% and 89.34%-99.03%, respectively. Therefore, organic-inorganic combined fertilization is the best nutrient management measure for carbon emission reduction in rice production in Liaoning Province.

Key words: rice, methane, nitrous oxide, organic-inorganic combined fertilization, straw returning, carbon sequestration and emission reduction

摘要：

水稻生产是碳排放的主要来源，辽宁省是中国重要的优质水稻主产区，探明稻田减排固碳潜力对实现碳达峰碳中和具有重要意义。遵循《IPCC国家温室气体清单指南2019修订版》的基本框架和要求，按照《省级温室气体清单编制指南》规定，估算分析了辽宁省稻田减排固碳潜力。结果表明，辽宁省稻田CH₄排放量（CO₂-eqv）为2.13-3.39 Tg·a^-1，N₂O直接和间接排放量（CO₂-eqv）分别为0.37-0.40 Tg·a^-1和0.08-0.09 Tg·a^-1。常规施肥碳排放总量（CO₂-eqv）为2.61 Tg·a^-1，优化施肥可减少碳排放（CO₂-eqv）0.03 Tg·a^-1，有机培肥和秸秆还田碳排放（CO₂-eqv）分别增加0.42 Tg·a^-1和1.36 Tg·a^-1，具有明显的增排效应，稻田单位面积碳排放强度和单位产量碳排放强度均以秸秆还田最高，较常规施肥分别增加了49.96%-52.68%和50.30%-52.46%。稻田单位面积碳排放强度（CO₂）以辽河三角洲稻区最高，达到5.17-8.08 t·hm^-2·a^-1。单位产量碳排放强度（CO₂）则以东南部山地丘陵稻区最高，达到0.66-1.01 t·t^-1·a^-1。不同水稻主产区以辽河三角洲稻区碳（CO₂-eqv）减排空间最大，达5.50×10⁴-1.42×10⁵ t·a^-1，不同化学肥料以氮肥减施带来的碳（CO₂-eqv）减排潜力最大，达0.18×10⁴-1.20×10⁵ t·a^-1，不同养分管理措施以有机无机配施碳（CO₂-eqv）减排空间最大，达3.78×10⁴-1.42×10⁵ t·a^-1。有机无机配施和秸秆还田土壤固碳量（CO₂-eqv）分别为0.10-0.28 Tg·a^-1和0.22-0.65 Tg·a^-1，其碳增排对土壤固碳抵消率分别为56.68%-82.52%和89.34%-99.03%，均能通过土壤固碳抵消其增加的碳排放。有机无机配施是辽宁省水稻生产碳减排最优养分管理措施。
