The total amount of soil CO2 emission under different straw management, irrigation and nitrogen application strategies were from 3494 to 4113 g CO2 m-2 a-1 Straw amended treatments showed a higher total CO2 emission than no-straw amended treatments; 不同农作措施下农田CO2释放总量的范围是3494~4113gCO2m~(-2)a~(-1)。秸秆还田处理比秸秆不还田处理具有更高的释放总量;
So, LOM and CMI could more than total organic matter objectively reflect changes in soil fertility and soil quality, and should be used as indices to describe soil quality and assess soil management. 这些结果暗示LOM和CMI比总有机质更能客观反映土壤肥力和土壤质量的变化情况,应该成为描述土壤质量和评价土壤管理的良好指标。
