摘　　要：为了研究生物腐植酸配施不同量化学肥料对土壤性质及作物产量的影响。通过盆栽试验,研究了生物腐植酸肥在作物生长过程中对土壤性质的影响。结果表明,生物腐植酸的施用可以减少化学肥料的用量,也可以提高土壤中全氮、有机质、碱解氮、速效磷、速效钾的含量,并达到改善土壤性质和提高油菜产量的目的。生物腐植酸和化学肥料的用量对土壤性质和油菜的产量有着显著的影响,所以油菜生长化学肥料的用量减少量应为20%。总体来看,生物腐植酸和肥料对油菜的生长具有多方面的影响因素,其用量及配比应该综合考虑土壤性质及肥料利用率的基础上确定。In order to study the effect of biological humic acid fertilizers with different amounts of chemicalfertilizer on soil properties and crop yield, through pot experiment, we studied the biological humic acidfertilizer during growing crops on soil properties. The results showed that the bio-active humic acid fertilizercould reduce the amount of chemical fertilizer, and also increase the content of soil total nitrogen, organicmatter, available nitrogen, available phosphorus, available potassium, and improve soil properties and enhancerape yield. The bio-active humic acid and chemical fertilizer had significantly affected soil properties and rapeyields, so the amount of chemical fertilizer on rape growth should be reduce by 20%. It was concluded that theinfluence of bio-active humic acid and fertilizer on rape growth was various, which meant that the bio-activehumic acid and fertilizer application amount and ratio should be established with an integrated consideration ofsoil properties and utilization efficiency of fertilizer.
