摘　　要：针对北京地区设施结球生菜种植农户过量施肥问题,进行含硝化抑制剂的生菜专用缓释肥应用效果研究,以探索减少化肥施用量和施用次数。以结球生菜‘射手101’为试验材料,在北京顺义多年蔬菜种植大棚,通过田间小区试验,设计不施氮对照(T_(0))、农户传统施肥一基两追(T_(1))、生菜专用配方肥一基两追施肥(T_(2))、生菜专用缓释肥一次性施肥(T_(3))、生菜专用缓释一基一追施肥(T_(4))、生菜专用缓释肥一基两追施肥(T_(5))6个处理,探究添加硝化抑制剂的生菜专用缓释肥对生菜生长性状、产量、硝酸盐含量、氮素利用率和经济效益的影响。结果表明,一基两追的施肥条件下,相比于传统农户施肥(T_(1)),不添加硝化抑制剂的生菜专用配方肥处理(T_(2))结球生菜的生长性状指标、产量指标、品质指标、氮素利用率和土壤无机氮转化均无显著差异;添加硝化抑制剂后(T_(4)),结球生菜的叶绿素含量显著提升16.7%,硝酸盐含量显著降低113.1%,可溶性糖含量显著提升44.4%,氮肥利用率显著提升43.2%,产量显著增加23.8%。对比添加硝化抑制剂条件下一次性施肥(T_(3))、一基一追(T_(4))、一基两追(T_(5))的施肥效果,在生长性状、产量指标、品质指标和氮素利用率上均无显著差异,伴随施肥次数增加,经济效益降低,一次性施肥处理(T_(3))分别比一基一追(T_(4))、一基两追(T_(5))处理净利润提升6.3%、24.9%。因此,作者认为一次性底施专用缓释肥不仅可以减少施肥人工投入,而且减少化肥施用,提升产量和氮肥利用率,可以作为北京地区结球生菜生产推荐的施肥措施。Regarding the issue of excessive fertilization of facility-grown head lettuce in Beijing,a study on the application effect of slow-release fertilizer for lettuce with nitrification inhibitors was conducted to explore reducing chemical fertilizer application rates and frequencies.Taking the head lettuce variety‘Archer 101’as the test material,through field plot experiments in a vegetable greenhouse with years of cultivation in Shunyi,Beijing,six treatments were designed,including no nitrogen control(T_(0)),traditional farmer fertilization with one basal application and two top dressings(T_(1)),special formulated fertilizer for lettuce with one basal application and two top dressings(T_(2)),special formulated fertilizer for lettuce with one-time application(T_(3)),special formulated fertilizer for lettuce with one basal application and one top dressing(T_(4)),and special formulated fertilizer for lettuce with one basal application and two top dressing(T_(5)).The study explored the effects of special slow-release fertilizer for lettuce with nitrification inhibitors on the growth traits,yield,nitrate content,nitrogen use efficiency,and economic benefits of lettuce.The results showed that under the fertilization condition of one basal application and two top dressings,compared with traditional farmer fertilization(T_(1)),the treatment of special formulated fertilizer for lettuce without nitrification inhibitors(T_(2))had no significant differences in growth trait indicators,yield indicators,quality indicators,nitrogen use efficiency,and soil inorganic nitrogen transformation of head lettuce.After adding nitrification inhibitors(T_(4)),the chlorophyll content of head lettuce increased significantly by 16.7%,the nitrate content decreased significantly by 113.1%,the soluble sugar content increased significantly by 44.4%,the nitrogen fertilizer use efficiency increased significantly by 43.2%,and the yield increased significantly by 23.8%.Comparing the fertilization effects of one-time fertilization(T_(3)),one basal ap
