| 摘 要： | 分析了甘肃马铃薯区域分布规律和产量特征，通过对不同生存区域土壤理化性质与产量关系的研究、提出影响甘肃省马铃薯分布的主要因素是社会需求而不是生态适应性。土壤有机质，氮，磷，钾及土壤孔性对马铃薯折产量都有不同程度的影响，但限制马铃薯产量上台阶主要因素是磷肥施用不足。

| Abstract: | Based on the study of the relation between potato yields and the physical and chemical features of the soil,it was found that the main factor affecting potato distribution is not its ecological adaptability but the social demands;the organic matter, N,P,K and the poresity of soil have different influences on potato yields,but the main hinderance is the insufficient application of P fertilizer. |
