摘要: 使用APSIM作物模型,模拟1981−2014年华北平原夏玉米、冬小麦−夏玉米、冬小麦−夏玉米−早播玉米1(提前10d)、冬小麦−夏玉米−早播玉米2(提前20d)四种种植模式下土壤有机碳(SOC)变化、土壤氧化亚氮(N2O)排放、土壤温室气体排放和产量的变化。结果表明:四种种植模式中,1981−2014年华北平原夏玉米种植模式下土壤N2O排放量最小(514.81kg·hm−2)、土壤主要温室气体平均排放量最少(0.30MgCO2-eq·hm−2);冬小麦−夏玉米−早播玉米1(提前10d)种植模式下土壤有机碳平均变化量最少,为120.78kg·hm−2;冬小麦−夏玉米−早播玉米2(提前20d)种植模式的土壤主要温室气体平均排放量次之,为0.76MgCO2-eq·hm−2;四种种植模式中,冬小麦−夏玉米种植模式的平均产量最高,为23405.47kg·hm−2;夏玉米种植模式下土壤主要温室气体排放效应最好(GHG=0.02 MgCO2-eq·hm−2),冬小麦−夏玉米−早播玉米2(提前20d)种植模式次之(GHG=0.04 MgCO2-eq·hm−2);在保证产量的前提下,考虑粮食安全、资源节约和环境友好各方面,冬小麦−夏玉米−早播玉米2(提前20d)两年三熟种植模式是华北平原较为理想的种植制度。

Abstract: The APSIM crop model was used to simulate the changes of soil organic carbon (SOC), soil nitrous oxide (N2O) emissions, soil greenhouse gas emissions and yield in the North China Plain from 1981 to 2014 under summer maize, winter wheat-summer maize, winter wheat-summer maize-early maize 1 (10 days in advance), winter wheat-summer maize -early maize 2 (20 days in advance) four cropping patterns. The results showed that among the four cropping patterns, the soil N2O emission in summer maize planting mode was the lowest, which was 514.81kg·ha−1, the average greenhouse gas emission of soil was 0.30MgCO2-eq·ha−1.The average change of soil organic carbon in winter wheat-summer maize-early maize1 (10 days in advance) cropping pattern was the least, which was 120.78kg·ha−1. The average greenhouse gas emission of winter wheat-summer maize -early maize (20 days in advance) was 0.76MgCO2-eq·ha−1. Among the four planting patterns, the average yield of winter wheat-summer maize was the highest, which was 23405.47kg·ha−1,the summer maize planting pattern had the best effect on soil greenhouse gas emissions(GHG=0.02 MgCO2-eq·ha−1), followed by the winter wheat-summer maize -early maize 2 (20 days advance) planting pattern(GHG=0.04 MgCO2-eq·ha−1). On the premise of ensuring the yield, considering the aspects of food security, resource conservation and environmental friendliness, the planting pattern of winter wheat-summer maize-early maize 2 (20 days in advance) will be an ideal planting system in the North China Plain.
