小麦、夏玉米两熟制是我省淮北地区重要的种植制度,但全年产量一直偏低。1989年承担了安徽省科委下达的“淮北地区小麦夏玉米亩产吨粮栽培技术体系研究”重点课题,经3年试验研究,圆满地完成了任务。试验示范区的11713.7亩,平均亩产达1029.4公斤。吨粮田在实现高产之后,其效益如何?有必要对这个问题作一探讨。经济效益是用成本和产值来衡量投入产出效率,比较不同系统间效率和不同措施的效果。能量
Wheat, summer maize double cropping system is an important planting system in Huaibei area of our province, but the annual output has been low. In 1989, it undertook the key issue of “Research on Technology System of Tillage Cultivation System of Wheat and Summer Maize in Huaibei Area” issued by Science and Technology Commission of Anhui Province. After three years of experimental research, the project was successfully completed. The experimental demonstration area of 11713.7 acres, the average yield of 1029.4 kilograms. After realizing the high yield of the grain field, what is the benefit? It is necessary to discuss this issue. Economic efficiency is the cost and output value to measure the efficiency of input-output, compare the efficiency of different systems and the effect of different measures. energy
