摘要
在55%田间持水量和等量施肥条件下,比较研究了施用水葫芦有机肥和畜禽粪有机肥对土壤CO2排放特征的影响。结果表明:水葫芦有机肥处理土壤的CO2排放量与累积排放量均显著低于畜禽粪有机肥处理土壤。有机肥处理土壤的CO2累积排放量与潜在可矿化有机碳含量以及有机碳矿化速率呈显著正相关。
The effects of using hyacinth organic fertilizer or poultry organic fertilizer on the soil CO2 emission were comparatively studied under the conditions of 55% field water capacity and applying equal quantitive fertilizer.The results showed that the emission and cumulative emission of soil CO2 in hyacinth organic fertilizer treatment were obviously smaller than those in poultry organic fertilizer treatment.The cumulative emission of soil CO2 in the organic fertilizer treatment showed obviously positive correlation with the potential mineralized carbon content and the speed of organic carbon mineralization.
