| 摘 要： | 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/hm2,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。

Main fertilizer application dose research, based on reduction of carbon footprint:A case study of cooperatives about vegetable production in Liuyang |
| |
| Abstract: | Objective]Fertilizer is one of the main factors that effects the crop yield and agricultural carbon. Method]This research which based on reducing the per unit yield of carbon footprint, tried to explore the reasonable dosage of main fertilizer. Through 3 years of point-survey that included 8 kinds of vegetables which were bitter gourd,Scucumber,Sbeans,Slettuce,Samaranth,Seggplant etc,in four cooperatives of Liuyang, and then we analyzed the relevant data. Result]The specific results are as follows: The optimal amount on seasonalSvegetable of N fertilizer,SP2O5 fertilizer,SK2O fertilizer and manure were 0, 327.2, 0 and 48936 kg?hm-2. In this fertilization levels, the per unit yield of carbon footprint was to be decreased by 85.85 percent and the yield of vegetables were increased by 24.11 percent. Conclusion]Therefore, reducing the use ofSN fertilizerSand K2OSfertilizer,Scontrolling of P2O5Sfertilizer and increasing application ofSmanure, are the keys to develop efficient and low-carbon vegetable planting industry in Liuyang. |
