摘　　要：为了提高肥料利用率和作物产量,在普通复合肥料中添加黄腐酸,研制了黄腐酸复合肥,并通过盆栽试验研究了不同施用量黄腐酸复合肥对土壤养分和小麦生长的影响。结果表明:普通复合肥添加黄腐酸没有显著提高土壤氮磷钾养分含量,与普通复合肥全量相比,黄腐酸复合肥全量可以提高小麦产量8.70%;黄腐酸复合肥减量20%,小麦产量无显著差异;黄腐酸复合肥减量30%、40%,小麦产量分别减产8.48%、15.55%;普通复合肥减量20%配施黄腐酸液体肥可使小麦增产15.41%。In order to improve fertilizer utilization and crop yield,the fulvic acid compound fertilizer was developed by adding fulvic acid to common compound fertilizer,for studying the effect of different application rates of fulvic acid compound fertilizer on soil nutrient and wheat growth by pot experiment.The results showed that the addition of fulvic acid to common compound fertilizer did not significantly increase the content of nitrogen,phosphorus and potassium in soil.Compared with the total amount of common compound fertilizer,the total amount of fulvic acid compound fertilizer could increase the wheat yield by 8.70%.The reduction of fulvic acid compound fertilizer by 20%had no significant difference in wheat yield.The reduction of fulvic acid compound fertilizer by 30%and 40%resulted in the reduction of wheat yield by 8.48%and 15.55%respectively,while the reduction of common compound fertilizer by 20%combined with application fulvic acid liquid fertilizer could increase wheat yield by 15.41%.
