摘  要：
分析了我国部分典型植烟区土壤腐殖质组成特征及其与部分土壤因子的关系,结果表明:(1)在所考察的典型烟叶产区中,植烟土壤腐殖质碳量集中分布在10-20 g/kg之间,平均为15.25 g/kg。胡敏酸比例、富里酸比例、胡敏素比例分别分布在11.05%-32.15%、12.00%-36.28%、38.43%-68.23%之间,胡富比值集中分布在0.7-1.3之间。(2)腐殖质碳量以东南烟区显著较高,黄淮烟区显著较低;胡富比以东南烟区显著较高,胡富比值达1.14,其它烟区土壤胡富比小于1。(3)水稻土腐殖质及组分碳量均最高,紫色土、红壤、棕壤次之,褐土最低。水稻土腐殖化程度显著较高,棕壤和红壤腐殖化程度显著较低。(4)土壤pH与腐殖质组成整体呈显著负相关关系。土壤的富里酸比例越低、胡富比越高,土壤碱解氮含量呈升高趋势。

摘  要：
Relationships between humus chemical composition and soil factors in typical tobacco-growing regions were analyzed.Results showed that:(1) carbon content(TC) of soil humus ranged from10 g/kg to 20 g/kg,with average of 15.25 g/kg.Proportions of humic acid(HA),fulvic acid(FA) and humin(HM) in humus carbon content were distributed in 11.05%-32.15%,12.00%-36.28% and 38.43%-68.23%,respectively.Most of HA/FA ratios ranged from 0.7 to 1.3;(2) TC in tobacco growing regions in southeast China was significantly higher than in other regions,with Huanghuai region was the lowest.The HA/FA ratio of tobacco growing regions in southeast China was significantly higher than in others,with an average value of 1.14,while in other regions it was less than 1;(3) Carbon levels of TC and humus composition in paddy soil were the highest followed by purple,red,and brown soils.The humification degree of paddy soil was also much higher than others;(4) soil pH values were significantly negatively correlated with humus composition.Alkali-hydrolyzable nitrogen content increased with decreasing soil FA/TC,or increasing HA/FA.
