目的:施用生物肥料是有助于保持或提高耕地土壤有机质含量并培肥土壤的重要措施之一。关于生物肥料对土壤有机质含量的影响已经取得了一些结果,但关于生物肥料对腐殖质组分构成的影响方面却知之甚少。材料与方法:本研究的目的是明确施用生物肥U Gmax对耕地土壤腐殖质层中总有机碳、溶解性有机碳和有机质部分组分如腐植酸碳、黄腐酸碳、腐黑物碳的影响。分别于2005年施用生物肥U Gmax前和2008年经2005-
Purpose: The application of biological fertilizer is one of the important measures to help maintain or increase soil organic matter content of cultivated land and to fertilize the soil. Some results have been achieved on the impact of biological fertilizers on soil organic matter content, but little is known about the impact of biological fertilizers on the composition of humus components. MATERIALS AND METHODS: The purpose of this study was to determine the effect of applying U Gmax on the total organic carbon, dissolved organic carbon and some components of organic matter such as humic acid carbon, fulvic acid and humic substances in the humus layer of arable land . Respectively, in 2005 before the application of bio-fertilizer U Gmax before 2008 and 2005-
