| 摘 要： | 2011年以鄂马铃薯7号为供试品种,开展了氮、磷、钾肥肥料效应试验,探索马铃薯平衡施肥技术结果表明,氮(N)不同施用量对鄂马铃薯7号产量影响显著,钾(K2O)、磷(P2O5)不同施用量对产量影响不显著；鄂马铃薯7号氮、磷、钾最佳施用量分别为172.5、67.5、90.0 kg/hm2,此时经济效益最好. |
| 关 键 词： | 氮肥 磷肥 钾肥 马铃薯 产量 效益 |

| Abstract: | An experiment about fertilizer effect of nitrogen fertilizer,phosphate fertilizer,potash fertilizer on Emalingshu No.7 was conducted to explore the balanced fertilization technique on potato in 2011.The result indicated that,nitrogen fertilizer had a significant effect on yield,but phosphate fertilizer and potash fertilizer had not significant effect on yield;The best combination of cultural factors for Emalingshu No.7 was N 172.5、P 67.5、K 90.0 kg/hm2,and it had the optimal economic benefit. |
| Keywords: | nitrogen fertilizer phosphate fertilizer potash fertilizer potato yield benefit |
