摘　　要：为了了解商品有机肥与NPK化肥平衡配合施用在莴苣作物上的应用效果,作者于2004年根据莴苣作物需肥规律、当地莴苣的产量水平与菜农的施肥习惯,进行了汇仁高效有机肥和NPK化肥的平衡配套施肥田间试验。试验结果表明:汇仁高效有机肥的施用,可在减少化学氮肥一半用量情况下,莴苣产量增加1.4%～10.8%;莴苣茎部的Vc含量增加,硝酸盐含量降低;纯收入增加6.34%～10.18%。并且推荐在莴苣作物上,以667m2基施150kg汇仁高效有机肥,配施纯氮13.7kg、五氧化二磷4.5kg、氧化钾13.5kg的化学肥料,纯收益最高;施用肥料的N、P2O5、K2O比例以1∶0.51∶左右较好。To understand the effect of application of commercial organic fertilizer combining balanced fertilization of NPK chemical fertilizer on lettuce, the field experiment in this paper was conducted in 2004. The experiment was designed according to the rules of lettuce needing fertilizer, the yield level of local lettuce, and the habit of peasant fertilizing. Results of the experiment showed as follows. With the application of Huiren high effective organic fertilizer at the rate half of N level of the control （CK）, the yield of lettuce increased by 1.4%-10.8%, while the quality enhanced with increased vitamin C content and reduced nitrate content in lettuce stem. Pure income of harvesting lettuce increased by 6.34%-10.18%. We recommended that the optimal fertilizing amount of Huiren high effective organic fertilizer is 150kg per 667m^2 in combination with chemical fertilizer of 13.7kg N, 4.5kg P2O5 and 13.5kg K20; the ratio of N, P2O5, K2O for fertilization of lettuce is approximately 1：0.5：1.
