| 摘 要： | 在中上肥力的地块进行马铃薯3414肥料效应试验，结果表明：马铃薯的最佳施肥量为纯N172．8kg/hm^2,P20s108．0kg/hm^2．K20178．5kg/hm^2；最高产量施肥量为纯N195．0kg/hm^2．P205109．1kg/hm^2、K20181．7kg/hm^2。试验还证明．充足的氮素供应对促进马铃薯前期茎叶的健壮生长有重要作用；适当的钾素养分对块茎膨大有促进作用，能提高马铃薯的产量。

| Abstract: | A potato＇s ＂3414＂ fertilizer effect experiment was conducted in middle and high fertility fields. The results show that the best fertilization amount for potato is pure N 172.8kg/hm^2,P2O5 108.0kg/hm^2,K20 178.5kg/hm^2,and the amount for highest yield is pure N 195.0kg/hm^2,P205 109.1kg/hm^2,K20 181.7kg/hm^2. This experiment has also proven that sufficient N supply can promote potato＇s growth in early peroids, rational K nutrient can boost its tuber enlargement and increase the crop＇ s yield. |
