摘　　要：为提高花生氮肥表观利用率和花生产量,将包膜尿素和普通尿素掺混施用,调查其对花生主要农艺性状、产量、氮肥表观利用率的影响。结果表明,普通尿素与包膜尿素掺混施用能有效改善花生百果质量等主要农艺性状,并提高其产量和氮肥表观利用率,其中以30%普通尿素掺混70%包膜尿素处理表现最好,产量达到7 622.2 kg/hm2,较不施氮肥对照增产37.75%,氮肥表观利用率达到34.6%,50%普通尿素掺混50%包膜尿素处理次之。In order to improve the nitrogen apparent efficiency and the growth of peanut, the effects of combined application of coated urea and common urea on the main agronomic characters,yield,nitrogen apparent efficiency were studied. The results showed that the combined application of common urea and coated urea could effectively improve hundred-fruit weight and other major agronomic traits,and increased the yield and nitrogen apparent efficiency,of which the treatment with 30% common urea combined with 70% coated urea had the best effect,the yield of the above treatment reached 7 622. 2 kg/ha,increased by 37. 75% compared with control without nitrogen fertilizer, the nitrogen apparent efficiency of the above treatment reached 34. 6%,the treatment with 50% common urea combined with 50% coated urea was the second.
