摘　　要：延津县农田投能已达到我国中低产地区的农田投能水平,无机能投入已超过全国平均水平.畜力能投入高是该地区农田投能的特点,有机肥能投入低是该地区农田投能中存在的问题.通过适度规模经营、农田基本建设、精耕细作和合理轮作,可以提高农田投能效率.The energy input into farmland in Yan Jing County has reached middle - low-yield area's level. The inorganic energy input into farmland has already exceeded our country's average value. High animal power input is the characteristics of this area in energy input into farmland. Lower organic manure input is still a problem in energy input in this area. Appropriate-scale-operation, farmland capital construction, intensive cultivation and proper rotation of crops are the ways to improve energy efficiency.
