以蔬菜长期施肥试验为基础,通过田间试验和室内分析的方法,研究了长期施肥条件下,不同施肥处理对土壤重组腐殖质总量,各结合形态腐殖质总量及其之间比值的影响。结果表明:施用有机肥处理的土壤重组腐殖质总量,松结态,稳结态,紧结态腐殖质总量和松/紧比值都大于不施有机肥的处理;各施肥处理,土壤的腐殖质都以松结态和紧结态为主,稳结态只占一小部分,但施有机肥处理的松结态腐殖质占重组的份额大于不施有机肥的处理;而稳结态和紧结态腐殖质则相反,即不施有机肥处理的稳结态和紧结态腐殖质占重组的份额大于施用有机肥的处理。 Based on the long-term fertilization experiment of vegetables, the effects of different fertilization treatments on the total amount of soil reorganized humus, the total amount of the combined forms of humus and the ratio among them were studied under the condition of long-term fertilization by field experiment and laboratory analysis. The results showed that the total amount of soil reorganized humus, loosely knotted state, steady state, tight knot humus content and loose / tight ratio of treated organic manure were all greater than those without organic manure. The fertilization treatments, soil humus Mainly in loosely knotted and tightly knotted state, and only a small part of steady state, but the proportion of loosely knotted humus treated with organic manure accounted for more than that without organic manure. However, steady state and tight knot On the contrary, the proportion of humus was the same as that of organic manure.
