摘　　要：采用随机区组设计,通过氮磷钾配施对马铃薯的产量进行效应分析。结果表明:合理施用氮磷钾肥对马铃薯有增产效果,其中施用氮肥8kg/667m^2、磷肥4.5kg/667m^2、钾肥12kg/667m^2产量最高,商品薯率、经济效益最好,与常规施肥处理相比均达1%极显著水平。Effects of nitrogen, phosphorus and potassium on the yield of potato were analyzed by using the randomized block test de- sign, combined with the production practice of early mature potato. The results show that , the reasonable application of NPK fertilizer on potato yield, nitrogen fertilizer, phosphate fertilizer per muincluding 8kg 4.5kg, 12kg the highest yield, commodity potato rate, the best economic benefit reached 1% significant level compared with the conventional fertilization treatment.
