摘　　要：在浙江省马铃薯主产区——丽水市,通过2年试验研究了马铃薯高产施肥措施对产量及相关性状的影响。试验表明,在当地习惯施肥基础上,提高氮磷至N-120 kg/hm2、P2O5-80kg/hm2,同时增施钾肥,提高了马铃薯产量、淀粉含量和商品率,提高了叶面积系数、叶绿素含量、干物质含量和净同化率。同时表明,增施磷钾肥不同处理效果不同,根据增产提质效果及实际效益,推荐施用量为:N-120 kg/hm2、P2O5-80kg/hm2、K2O-170kg/hm2、农家肥104kg/hm2。After two year＇s experiments in Lishui, the main potato producing area of Zhejiang, the effects of fertilization measures for high production of potato on its production and related traits are examined. The result of the tests indicates that the potato production, the starch content and the commodity rate can be improved as well as leaf area index, chlorophyll content, net assimilation rate and solids content can be increased by increasing the amount of nitrogenous fertilizer to 120 kg/hm^2 and phosphate fertilizer to 80 kg/hm^2 and at the same time increasing the potassium fertilizer on the basis of the usual fertilization in local area. In the meanwhile, the result of the tests shows that different disposal methods of usual fertilization in local area. In the meanwhile, the result of the tests shows that the different disposal methods of phosphate and potassium fertilizer lead to different production effects. According to the need of increasing production, enhancing quality and promoting benefit, we recommend the dosage： N- 120kg/hm^2, P2O5-80kg/hm^2 , K2O--170kg/hm^2, farmyard manure 10 000kg/hm^2.
