摘　　要：在本试验基地的生态条件下,当氮磷肥适宜不变时,单方面改变钾肥的施用量且随着施用量的增加,荷兰2-12马铃薯的栽培效果不断提高,以190和240 kg.hm-2的钾肥施用量栽培效果最佳,产量、品质及生理状况表现最佳,与对照相比差异极显著,但两者之间的差异不明显,后者较前者提高的不多,从经济效益的角度考虑,建议选择190 kg.hm-2的钾肥施用量。The result of research indicated that the effect of Dutch2-12 potatoes cultivating increased continuously by increasing the dosage of potassium fertilize. The effect is best when the potassium fertilize dosage reached 190 or 240 kg·hm^-2. And the output, quality and the physiological condition are also best. However, there are no obvious differences between the two dosages. By considering the economic benefit, the dosage of 190 kg·hm^-2 is recommended.
