肥料是影响作物产量和农业碳排放的主要因子之一。研究基于减少单位产量碳足迹,探讨主要肥料的合理用量。对浏阳4个合作社中黄瓜、苦瓜、豆角、莴笋、苋菜、茄子等8种蔬菜生产进行3年定点调查,并对相关数据进行统计分析。结果表明：每季蔬菜生产氮肥、磷肥、钾肥、厩肥施用量依次为：0、327.2、0、48936 kg/hm^2,可使单位产量碳足迹减少85.85%,产量提高24.11%。因此,浏阳发展高效低碳蔬菜种植产业关键施肥技术在于减少氮肥与钾肥的使用,控制磷肥的用量,增施厩肥。

Fertilizer is one of the main factors that affect crop yield and agricultural carbon emission. Thisresearch explored the reasonable dosage of main fertilizers based on reducing the per unit yield of carbonfootprint. The author statistically analyzed data of point-survey from four cooperatives of Liuyang through 3years on 8 kinds of vegetables, which were bitter gourd, cucumber, beans, lettuce, amaranth, eggplant, etc. Thespecific results were as follows： the optimal amount of N fertilizer, P2O5 fertilizer, K2 O fertilizer and manure onseasonal...
