摘　　要：本文分析了养分管理在旱作马铃薯生产中的必要性和重要意义,根据马铃薯的养分需求规律和养分特性等提出了根据土壤Nmin进行氮素总量确定,磷钾恒量监控和中微量元素因缺补缺的管理建议。Conducting nutrient resource management in rainfed potato is of significance,however there is no theory presently to guide the nutrient resource management practice in rainfed potato production although it accounts for most part of potato production in China.Basing on nutrient requirments of potato and nutrient chemical characters,some suggestions about nutrient management principles was made in this review.For nitrogen,the total account may need to be dertermined by soil Nmin test,and long term detects for phosphorus and potassium in soil may and their constant keeping may be practical.As to micronutrients,supplement is necessary only for deficiencies.
