摘　　要：长润复合肥在莴苣(Lactuca sativa)上施用后,株高、茎粗和单株重增加,莴苣经济性状得到明显改善。在莴苣上施用长润复合肥处理较不施肥处理增产达53.93%。该复合肥与等量进口复合肥施用对比,其产量基本相当,但其经济收益明显增加。长润复合肥比例合理,施用此复合肥促进了作物对氮、磷、钾的平衡吸收,提高了肥料的利用效率,有较好的增产、增收效果,可替代进口复合肥在莴苣上施用。In order to study the effect of Changrun high tower compound fertilizer on lettuce （Lactuca sativa）,a field experiment was conducted in Yunmeng County.The results showed that economical characteristics of lettuce were significantly improved.The plant height,stem width,plant weight were increased with Changrun compound fertilizer.Yield of lettuce in the Changrun compound fertilizer treatment increased 53.93％ in contrast with the control （no fertilizer）.Economical benefit was enhanced significantly in the Changrun compound fertilizer treatment compared with the imported compound fertilizer treatment.The ratio of Changrun compound fertilizer could accelerate N,P,K uptake of lettuce,then utilization efficiency of fertilizer was increased.In a word,Changrun compound fertilizer could replace imported compound fertilizer in lettuce.
