1991～1993年的定位分析表明,双季稻吨粮田与一般高产田比较,成本下降1.55%,产品亩产量与能产量则大幅度增加,因而最终表现为经济效益高,能量效益高和社会效益高.亩产吨粮,需投入成本429.50元(油稻稻)或386.34元(肥稻稻),投入能量4824.40 MJ(油稻稻)或4594.87MJ(肥稻稻),投入纯 N 30kg,P_2O_5 10kg,K_2O 20kg 左右.目前,吨粮田的投入水平仍处于“报酬递增期”.在江西赣抚平原及其类似条件的高、中产地区,已具备实现亩产吨粮的生产条件.
Positioning analysis from 1991 to 1993 showed that the cost per ton of grain cropland of double cropping rice dropped 1.55% as compared with that of general high yield cropland, while the yield per mu and yield of the product increased substantially. As a result, the economic performance was high, the energy efficiency was high, and society The output per mu is 429.50 yuan (oil rice) or 386.34 yuan (fat rice), 4824.40 MJ (oil rice) or 4594.87MJ (fat rice) At present, the input level of the grain cropland is still in the period of “increasing returns.” In the high and middle producing areas of the Jiangxi Provine Plain and its similar conditions, the production conditions have been met to realize the output per mu of grain.
