摘　　要：采取盆栽试方法,研究马铃薯马铃薯施含氯化肥及不同磷、钾肥效应,结果表明:在贵州生态条件下,施用K2SO4和KCl马铃薯产量差异不显著,但不能同时施用氯化铵与氯化钾;在氮钾肥为中量不变时,随着磷肥用量增加,马铃薯产量递增;在氮磷肥为中量不变时,随着钾肥用量增加,马铃薯产量也呈递增趋势。A pot experiment was conducted to study the effects on potato by applying chlorine-containing chemical fertilizer and different P and K fertilizers. The results showed that in Guizhou ecological conditions, yield was not significant when applied K2SO4 and KC1. But application of ammonium chloride and potassium chloride on potato at the same time was not allowed. When applied the same amount of nitrogen and potassium, potato yield increased with the increment of phosphate fertilizer. The yield also showed an increasing trend with the increment of potash when the amount of nitrogen and phosphorus was unchanged.
