为探讨功能菌型复合肥及化肥减量条件下栽培蔬菜的养分吸收特性及利用特征,在露地和大棚种植体系下,以结球甘蓝为试验材料,采用田间小区试验研究不同养分配比功能菌型复合肥及减量施用对结球甘蓝物质积累、养分吸收及肥料利用率的影响。结果表明,不同种植体系下,施肥处理对结球甘蓝生长后期干物质累积及N、P、K养分吸收速率,收获期N、P、K累积及肥料利用率效应显著。与常规施肥处理相比,露地和大棚种植体系下施用功能菌型复合肥处理结球甘蓝收获期干物质累积量分别增加2.4%~5.7%和4.9%~10.8%,N肥吸收利用率分别增加10.8~35.4和9.4~57.6个百分点。减量25%功能菌型复合肥处理较等量处理结球甘蓝N累...

To investigate the nutrient absorption and utilization of vegetable cultivation under functional bacterial compound fertilizer and reducing application, field plot experiments were conducted using the cultivation systems of open field and greenhouse to explore the effects of different fertilization treatments on the accumulation, nutrient absorption and fertilizer utilization efficiency of head cabbage (Brassica oleracea L.var.capitata L.). The results showed that under different planting systems, fertilization treatment had a significant or extremely significant effect on dry matter accumulat...
