摘　　要：利用腐植酸保水剂与氮、磷、钾肥料制成了腐植酸复合肥,并将该肥在半干旱区进行了玉米田间水肥耦合试验。试验结果表明:腐植酸复合肥使玉米株高增加、根系活力增强、叶绿素含量增加,为玉米优质高产奠定了基础。腐植酸复合肥处理与NPK复合肥处理相比,玉米不同生长期植株体内含磷量均增加,差异达极显著水平,说明施用腐植酸复合肥,使肥料中的磷活性增加,磷的利用率明显提高。施用腐植酸复合肥后,土壤团粒结构、土壤水分含量均增加,说明施该肥后,改善了土壤的物理性质。综上所述,腐植酸复合肥通过改善土壤物理性质和增效肥料,促进水肥耦合效应,促进了玉米生长和增产。Humic acid compound fertilizer was made from humic acid water retention agent,composing with nitrogen,phosphorus and potassium.Maize field water-fertilizer coupling experiment was carried out in semi arid area.The results showed that humic acid compound fertilizer could increase maize plant height,root activity and the content of chlorophyll,that were necessary for high yield and high quality of maize.Compared with the NPK compound fertilizer treatment,humic acid compound fertilizer significantly increased the content of phosphorus in different growth period of maize,that indicated using it improved the activity of phosphorus and phosphorus utilization rate.The soil aggregate structure,soil moisture content all increased,indicated that humic acid compound fertilizer improved the soil physical properties.In conclusion,humic acid compound fertilizer could increase the efficiency and the coupling effect of water and fertilizer,then promoted the growth and increased the yield of maize.
