摘要： 土壤碳含量是评价土壤质量的重要指标，对土壤物理、化学以及生物学性质都有重要的影响。增加土壤碳的含量不但有助于农业生产的可持续发展，而且对整个地球生态系统的物质循环也有着至关重要的作用。笔者研究了从有机废弃物发酵产物中提取的生物腐植酸对土壤碳组分的影响。结果表明：腐植酸、有机肥均能在一定程度上显著增加土壤总有机碳的含量，其中腐植酸+化肥处理能在较长的时间内（10~40天）保持土壤有机碳含量，其土壤有机碳碳含量增加了1.6%~10.5%。不同施肥处理土壤水溶性有机碳含量存在差异，与对照相比，腐植酸+化肥处理土壤水溶性碳含量增加了2.7%~20.1%。施肥处理能保持土壤微生物生物量碳含量，腐植酸添加量为400 mg/kg时施肥处理土壤微生物生物量碳含量显著高于对照处理。

Abstract: The content of soil carbon is an important indicator for the evaluation of soil quality, it could significantly affect the physical, chemical, and biological properties of soil. The increase of soil carbon content not only contributes to the sustainable development of agricultural production, but also plays a vital role in maintaining the cycle of the earth ecosystem. The author studied the effects of biology humic acid, which was extracted from the tunning of organic waste, on the component of soil carbon. The results showed that humic acid and organic fertilizer could significantly increase the content of soil total organic carbon to a certain extent. The treatment of humic acid chemical fertilizer could maintain soil organic carbon content in a long time (10-40 d), and the soil organic carbon content increased by 1.6%-10.5%. The contents of soil water soluble organic carbon were different in different fertilizer treatments, compared with CK, the soil water soluble organic carbon content increased by 2.7%-20.1% in the treatment of humic acid chemical fertilizer. Fertilization treatments could maintain the content of soil microbial biomass carbon, which was significantly higher than that of CK under humic acid content of 400 mg/kg.
