摘要
选用早熟品种‘荷兰15号’原种1代种薯为试验材料,研究了不同氮磷钾配比对马铃薯农艺性状、产量和干物质含量的影响。结果表明:增加茎粗和分枝数可以提高块茎的产量;合理的氮磷钾配比可以显著提高茎粗和增加分枝数,进而增加马铃薯的产量;氮磷钾配比对块茎干物质含量的影响不大;每667 m2施氮(N)14.4 kg、施磷(P2O5)9.6 kg、施钾(K2O)17.6 kg,可以获得较高的马铃薯产量。
Influence of various NPK combinations on agronomic traits, yield and dry matter content was studied using early maturing ＇Helan 15＇ as plant material. The results indicated that the increase in stem diameter and branch number increased tuber yield; reasonable NPK combination increased stem diameter and branch number, therefore increasing tuber yield; various NPK combinations tested in this experiment had no significant effect on dry matter content; the combination of N 14.4 kg, P2O59.6 kg and K2O17.6 kg based on 667 m^2gave the best yield.
