研究了不同培肥措施对冀东褐土腐殖质组成及其性质的影响。结果表明 ,采用有机肥 (物 )料配施化肥 ,可明显提高土壤可浸提腐殖酸含量和胡敏酸 (HA)、富里酸 (FA)含量及HA/FA比值 ,使胡敏酸得到活化和更新 ,肥力提高 ;而长期不施肥或单施常量化肥 ,使土壤腐殖质组成及其性质均有所恶化 ,土壤肥力水平下降。采用有机肥 (物 )料配施化肥是冀东地区实现农业可持续发展的有效途径。
The effects of different fertilization treatments on the composition and the properties of humus in the eastern Cinnamon soil were studied. The results showed that the organic manure (material) with chemical fertilizers can significantly improve the soil extractable humic acid content and humic acid (HA), fulvic acid (FA) content and HA / FA ratio, humic acid Activation and renewal, fertility increase; and long-term non-fertilization or single application of chemical fertilizers, soil humus composition and properties have deteriorated, soil fertility levels decline. The use of organic fertilizer (material) with chemical fertilizers is an effective way to achieve sustainable agricultural development in eastern Hebei.
