摘　　要：山东省属马铃薯中原二季作地区,产量和效益居全国首位。为了实现合理的养分管理和马铃薯生产的高产、高效,调查了山东省马铃薯主产区的土壤营养状况,在施肥与不施肥条件下分析了肥料利用效率和增产效果。结果表明：在长期大量施肥的情况下,马铃薯主产区的土壤肥力以滕州最高,造成该地区施肥增产只有5%左右,抵消肥料投入后与不施肥相比较666.7m^2收入反而减少187元,威海与肥城施肥增产20%以上,抵消肥料投入后与不施肥相比较666.7m^2收入增加400-500元。总体来看,山东省马铃薯主产区施肥过量,肥料利用率低,而且导致土壤和水资源富营养化。所以在马铃薯生产中,应加强肥水管理,进行科学施肥。Shandong Province is the two-cropping area of potato in the Central Plain,and its yield and benefit rank the first in China.In order to realize reasonable nutrient management,high yield and high benefit of potato production,the soil nutrient status of main potato producing areas in Shandong Province was investigated.The fertilizer use efficiency and its yield increasing effect were also analyzed under the conditions of fertilization and no fertilization.The results showed that under the condition of long-term fertilization with large amount,Tengzhou had the highest soil fertility,which resulted in only about 5% yield increase but 187 yuan per 666.7m^2 decrease of net benefit compared to no fertilization; in Weihai and Feicheng,the potato yield increased by more than 20% by fertilization,and the net benefit could increase by 400 - 500 yuan.Overall,excessive fertilizers were applied in the major potato producing areas of Shandong Province,which resulted in low use efficiency of fertilizer and eutrophication of soil and water.So the fertilizer and water management should be strengthened for scientific fertilization during potato production.
