以荷兰15马铃薯一级种薯为试验种植材料，探讨了定量磷钾肥条件下氮肥4种施用量对马铃薯荷兰15鲜薯产量与商品薯产量的影响。结果表明，纯氮用量40kg/667㎡的鲜薯产量与商品薯产量最高，每667㎡分别为2516.7kg和2290.3kg。纯氮用量40kg/667㎡的鲜薯产量和商品薯产量极显著或显著高于不施氮、纯氮用量20、60kg/667㎡的鲜薯产量和商品薯产量；纯氮用量40kg/667㎡的经济效益最高，为832.6元，比不施氮、纯氮用量20、60kg/667㎡分别增效681.3、564.1和572.7元。综合考虑，种植马铃薯荷兰15纯氮用量40kg/667㎡最适宜，此氮肥施肥量的鲜薯产量与商品薯产量及经济效益均最高。

To ifnd out the impact of 4 different dosage of nitrogen fertilizer on production of the fresh potato and commodity potato, we researched the whole planting process of the Netherlands potato (No.15) by some contrast experiment. As a result, the dosage of pure nitrogen which was 40kg/667㎡got the highest yield of fresh potato and commodity potato, fresh potato 2516.7kg/667㎡and commodity potato 2290.3kg/667㎡, while economic beneift was also the highest, which is 832.6 yuan RMB. In this condition, the production increased more signiifcantly than no nitrogen fertilizer and other dosages of pure nitrogen(20 or 60kg/667㎡). So we got the conclusion that the dosage of pure nitrogen 40kg/667㎡was the best in planting the Netherlands potato (No.15).
