摘　　要：　通过大棚小区试验,研究不同形态化学氮肥及有机无机复混肥对夏季小白菜绿星产量及品质的影响。结果表明:施用有机无机复混肥Ⅰ的小白菜产量最高,分别比施用等氮量的硝酸铵、硫酸铵、尿素、有机无机复混肥Ⅱ及无肥对照增产14 4%、6 3%、10 6%、4 6%及33 6%。在施用无机肥的3个处理中,施用硫酸铵的小白菜产量最高;施用硝态氮肥、铵态氮肥等不同形态氮肥处理之间,小白菜绿星体内的硝酸盐含量无显著差异(P>0 05);小白菜绿星对不同形态氮肥的氮素表观利用率以有机无机复混肥Ⅰ处理最高,达到29 7%。This paper deals with the effects of application of organic-inorganic compound fertilizers and inorganic nitrogen fertilizers on quality and yields of Chinese cabbage.The main results were as follows:(i) Application of organic-inorganic compound fertilizer I produced the highest yield among all the treatments.The yield increased by 14.4%,6.3%,10.6%,4.6% and 33.6% respectively,compared with the treatments of nitrate ammonium,sulfate ammonium,urea,organic-inorganic compound fertilizer Ⅱ and control.Among the three treatments of inorganic nitrogen fertilizers,the treatment of sulfate ammonium got the highest yield.(ii)No significant difference in nitrate content of Chinese cabbage Luxing was observed between the treatments with nitrogen fertilizers of different N forms (P>0.05).(iii) Of all the nitrogen fertilizers of different N forms,organic-inorganic compound fertilizer I was absorbed by Luxing at the highest apparent utilization rate of 29.7%.
