摘　　要：以V7马铃薯为试验材料,采用随机区组设计,探究不同肥料对马铃薯经济性状及肥料利用率的影响。结果表明:与不施肥对照相比,施用复合肥、缓释肥、水溶肥均可增加马铃薯单株结薯数、单株薯重、商品率、产量、干物质含量和淀粉含量,以施用复合肥表现较好;且施用复合肥时,肥料利用率较高。说明施用复合肥可以提高肥料利用率及马铃薯产量和品质。Using V7 potato as experimental material,the effects of different fertilizers on potato economic characters and fertilizer utilization rate were studied by randomized block design.The results showed that,compared with the control without fertilization,the application of compound fertilizer,slow-release fertilizer and water-soluble fertilizer could increase the number of tubers per plant,tuber weight per plant,commodity rate,yield,dry matter content and starch content,and the application of compound fertilizer had better performance.Moreover,when compound fertilizer was applied,the fertilizer utilization rate was higher.It showed that the application of compound fertilizer could improve the fertilizer utilization rate and the yield and quality of potato.
