摘　　要：为研究腐植酸复合肥对玉米产量、氮肥表观利用率及土壤硝态氮含量的影响,通过与不施肥及普通复合肥相比较,找出最佳腐植酸施肥含量配比。试验设腐植酸含量为0.1%、0.2%、0.3%、0.4%、0.5%、0.6%的6个水平腐植酸复合肥,经田间试验,结果表明:腐植酸复合肥均能够提高夏玉米产量,腐植酸的添加剂量不同,增产效果差异较大。与普通复合肥处理相比,腐植酸复合肥增产22.74~66.67 kg/667 m^(2)(4.35%~12.76%),差异达到极显著水平,其中以0.6%腐植酸含量处理产量最高(589.29 kg/667 m~2)。与普通复合肥处理相比,腐植酸复合肥各个处理氮肥表观利用率提高1.72~12.03个百分点,且均不同程度地降低了土壤中的硝态氮含量。In order to study the effects of humic acid compound fertilizer on maize yield,nitrogen apparent recovery fraction and soil nitrate nitrogen content to obtain the best ratio of humic acid fertilizer content,it was compared with no fertilizer and ordinary compound fertilizer.Field experiments with humic acid content of 0.1%,0.2%,0.3%,0.4%,0.5%,0.6%for six groups were conducted.The results show that the humic acid compound fertilizer could improve the yield of summer maize,and the additive amount of humic acid was different,and the yield increase effect was quite different.Compared with ordinary compound fertilizer treatment,the yield of humic acid compound fertilizer were increased by 22.74~66.67 kg/667 m^(2)(4.35%~12.76%),and the difference reached a very significant level,among which the yield of 0.6%humic acid content was the highest(589.29 kg/667 m^(2)).Compared with ordinary compound fertilizer treatment,the nitrogen apparent recovery fraction of humic acid compound fertilizer was increased by 1.72~12.03 percentage points,and the nitrate nitrogen content in the soil was reduced to varying degrees.
