| 摘 要： | 通过氮磷钾配合施用试验,观察其对马铃薯产量的影响,结果表明,施用氮磷钾肥的马铃薯增产效果最好,其中,N120P67.5K210施肥组合为增产最佳组合。氮素起决定性作用,只有在施氮肥的基础上,磷、钾才能最大限度地发挥作用。

| Abstract: | Through combination fertilization of N,P and K,its effects on yield of potato were observed.The results indicated that,N,P and K fertilization had obvious effects to increase yield of potato,in which the optimal combination was N120P67.5K210.Nitrogen played a decisive role;As for K and P,it could only be effective when N was applied. |
