| 摘 要： | 试验以马铃薯品种大西洋和尿素、过磷酸钙以及硫酸钾镁肥料为供试材料,采用"3414"田间试验设计,研究氮、磷、钾肥对马铃薯产量的影响。结果表明:氮、磷、钾不同施肥量对马铃薯的经济性状影响不大,对马铃薯产量影响较大,每公顷施N 300 kg、P2O5 150 kg、K2O 150 kg马铃薯的产量最高,产量为51 669 kg/hm2,并根据试验结果得出马铃薯肥料效应方程,计算出马铃薯最佳施肥量和最大施肥量。

| Abstract: | The effects of nitrogen,phosphorus and potassium fertilizer on potato yield were studied in a 3414 experimental design using the potato variety Atlantic as plant material.The level of each fertilizer did not have much impact on economic traits,but influenced the tuber yield.The treatment of N 300 kg,P2O5 150 kg,and K2O 150 kg per hectare gave the highest tuber yield,51 669 kg / ha.Furthermore,fertilization equation was obtained,based on which,optimal fertilization for highest economic benefit and highest tu... |
