对五个土类的高、中、低三个肥力水平的土壤和三种培肥措施的土壤进行了土壤腐殖质数量与品质的研究,结果表明,不仅在腐殖质含量与土壤肥力相关,腐殖质的品质(被活化的腐殖质)与作物产量更为密切。有机培肥措施在腐殖质的数量与品质上都起着积极的作用。建议以易氧化腐殖质和HA/FA值等作评价土壤肥力指标。
The quantity and quality of soil humus were studied on soil with three high, medium and low fertility levels and three soil fertility measures in five soil types. The results showed that not only the humus content was related to soil fertility, but also the humus quality (Activated humus) and crop yield more closely. Organic fertilization measures have a positive effect on the quantity and quality of humus. It is suggested to evaluate the soil fertility index based on the susceptible humic substances and HA / FA values.
