摘　　要：为探讨在宁南山区不同施肥处理下马铃薯生长发育和产量最佳施肥方式，采取随机区组设计进行田间试验，开展对马铃薯产量和品质影响的研究。结果表明，在当地条件下，处理10收获期干物质积累总量平均比对照增加30．97％，各施肥处理收获期的干物质累积量比对照增加7．35％～73．31％。马铃薯生长发育最佳施肥方式是N 300kg／hm^2、P2O5 200kg／hm^2、K2O 200kg／hm^2、M 17．5t／hm^2，（氮肥基施和追肥各一半，磷肥和钾肥以及有机肥全部基施），能增加马铃薯产量并能增加淀粉含量，从而提高马铃薯产品品质。在宁南山区马铃薯生产中可以推广应用这种肥料组配方案。For the best way that different fertilizer application on growth and yield of potato in Ningnan mountain area, this paper used the method of random sections in film experimentation to study. The result showed that treatment 10 the total of dry biomass increased 30. 97% average in harvest season, and other treatments increased in 7. 35% -73. 31% than CK. Using the combination of organic fertilizer, N, P, K, in which N was used as the basal fertilizer and repeat fertilizing once more in the burgeon time was the best way, which the yield and character of potato was the best and increased starch content and then improved the quality. It also showed that the combination of fertilizer could be extended in the yielding of potato in the Ningnan mountain area.
