为研究氮磷钾配施及种植密度对马铃薯产量和品质的影响，以费乌瑞它为试验材料，采用“3414＋2”的试验设计方法，分析各处理马铃薯植株农艺性状、地上部生长和块茎的相关性及植株产量和淀粉含量。结果表明：植株株高、茎叶鲜重和最大叶面积与植株的块茎鲜重呈显著正相关，主茎粗与块茎鲜重不存在相关性；施钾水平的高低对马铃薯产量的影响较大，马铃薯高产优质的最佳施肥方案为纯 N 8 kg／667m2、P2 O59 kg／667m2、K2 O 16 kg／667m2，种植密度5000株／667m2。

In order to explore the effects of N-P-K ratio and planting density on yield and quality of potato,taking favorite as the test material,a “3414+2”experiment was conducted to analyze agronomic traits,correlation of growth of aboveground part with tuber,plant yield and starch content.Results:Fresh tuber weight was significantly positively correlated with plant height,fresh stem and leaf weight, and maximum leaf area.Main stem diameter has no correlation with fresh tuber weight;Influence of potassium application level on potato yield was larger than others.The optimum application rate was N 8 kg/667m2 ,P2 O5 9 kg/667m2 ,K2 O 16 kg/667m2 ,the optimal planting density was 5 000 plants/667m2 .
