摘  要：
结合宁夏马铃薯战略性产业基地,定位研究马铃薯专用肥与生产中常规应用的普过磷酸钙肥料的增产增收效益和水分生产效率,探索最佳专用肥养分配比和合理施肥量。通过分组定位对专用肥其增产效果研究,结果表明,两种肥料在等量施肥标准条件下,专用肥料处理区田间长势和生长综合评判结果,植株长势健壮,叶色深绿,平均单株产量和薯块商品率高。专用肥较普磷酸钙增产32.54%￣46.28%,水分生产效率(WUE)提高34%。瘠薄地力施用专用肥增收率较普磷酸钙肥提高14.9%￣34.6%,中等地力农田施用专用肥增收率提高33.5%￣53.1%。

摘  要：
Effects and water-fertilizer production efficiency of compound fertilizers specified and traditional fertilizers were studied. The ratio of compound fertilizer specified and economic optimum fertilization were investigated through location research, the result showed that plant presented strong growth vigor , leaves were bottle-green, the average output per plant and commodity potato rate were increased with compound fertilizer specified under the same condition of fertilizing. Compared with traditional fertilizers, Plant yield increased 32.54%~46.28% under compound fertilizers specified for potato, and water use efficiency (WUE)increased 34%. Compared with traditional fertilizers, plant yield increased 14.9%~34.6% under compound fertilizers specified for potato in poor fertility site, and increased 33.5%~53.1% in middle fertility site.
