山东省“黄淮海中低产地区夏秋粮均衡增产综合栽培技术研究”,是“六五。期间国家科委下达的重点攻关课题。该项研究组装配套了小麦为“八项改革,二个坚持”,玉米为“一换、二增、三早、四改”的夏秋粮增产技术体系,在山东省平原、茌平、惠民、郓城等四个县的5.7万亩中心开发区实施,取得显著的增产效果和经济效益。1985年平均亩产604.5公斤,比开发前三年平均增长1.7倍。中心开发区和带动面三年累计增产粮食24.85亿公斤,增加收入5.7亿元。按照科技效益计算,增产粮食5.05亿公斤,增加纯收入1.17亿元,国家投资与科技效益比为1∶346。在取得突出经济效益的同时,还取得八项
Shandong Province “Huang-Huaihai low-yielding areas of summer and autumn grain balanced increase comprehensive cultivation technology research” is “65. During the key issue issued by the State Science and Technology Commission, the study assembled supporting the wheat as” eight reforms, two adhere to “ , Corn as ”a change, two increase, three early, four changes," the summer and autumn grain production technology system, in Shandong Plain, Chiping, Huimin, Yuncheng four counties of 5.7 million mu of central implementation zone development zone, made Significant yield increase and economic benefits .In 1985, an average of 604.5 kilograms per mu, an average increase of 1.7 times the previous three years of development.Central Development Zone and the driving force for three years cumulative increase of 2.485 billion kg of grain, an increase of revenue of 570 million yuan .In accordance with scientific and technological benefits Calculated to increase grain output 505 million kg, an increase of net income of 117 million yuan, the national investment and science and technology efficiency ratio of 1:346. In achieving outstanding economic efficiency, but also made eight
