【摘要】 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。更多还原

【Abstract】 In this paper, the effect of improving soil fertility on composition and characteristics of humus in cinnamon soil was studied After using organic fertilizer combining with chemical fertilizer, the content of the extractive humus acid of soil and that of HA and FA were raised The rate of HA/FA became higher HA was activated and renewed The soil fertility was improved However, no fertilizer or using mere constant chemical fertilizer would make the composition and characteristics worse and the soil fertility decline The composition and characteristics of humus were important indices to reflect the effect of improving soil fertility Organic manure used together with chemical fertilizer was the effective way to bring about sustainable development of agriculture更多还原
