| 摘 要： | 根据长武县旱塬地小麦连作长期定位试验研究,耕作和长期单施化肥可以维持土壤有机质水平,但加速了土壤腐殖质的老化,影响了胡敏酸和富里酸间的相互转化和土壤中有效养分的利用。化肥种类和施用量的不同其影响结果也不相同,单施磷肥对土壤培肥作用不明显,单施氮肥则能达到增加土壤肥力的效果,施用量愈大,效果愈明显。 |
| 关 键 词： | 有机碳 腐殖质组成 结合形态 单施化肥 |

| Abstract: | Based on fertilizer experiments located in a dry highland of Changwu county of Shanxi province,a study showed that chemical fertilizer application and cultivation could conserve soil fertility,while the soil organic matter became aged,and the impact was obvious in the translation of humic acid(HA) to fulvic acid(FA).Translation and distribution of HA and FA were influenced by different fertilizers.The effect of N fertilizer was higher than that of P fertilizer,and it increased with the increasing amount of fertilizers. |
| Keywords: | Organic carbon Organic matter compositions Combined carbon Single fertilizer |
