摘要： 对韭菜氮肥施用品种、氮肥最佳使用量和氮、磷、钾合理配比进行了研究。结果表明，韭菜适宜施用的氮肥品种为硫酸铵和尿素，碳酸氢铵、硝酸铵和氯化铵增产效果较差。在中等肥力石灰性土壤上，露地栽培的韭菜适宜的氮、磷、钾肥用量为：每hm2纯N450-530kg，P2O5378kg，K2O440kg，N：P2O5：K2O=1：0.77：0.90。

Abstract: The varieties and best dosage of N fertilizer and appropriate ratio of N, P and K were studied on leek in this paper. The results showed that the varieties of N fertilizer fitting to apply to leek were (NH4)2SO4 and Urea, but the effects of NH4HCO3, NH4NO3 and NH4Cl were weak on yields increasing. On the calcareous soil in middle fertility, the appropriate dosages of N, P and K fertilizers applying to leek planted in the field are 450-530kg N/hm2, 378kg P2O5/hm2 and 440kg K2O/hm2, the appropriate ratios of N, P and K fertilizers applying are 1:0.77:0.90.
