摘要
精准农业是当今世界农业发展的新潮流 ,中国 2 1世纪农业的发展方向之一。稻谷产量占我国粮食总产量的 4 0 %左右 ,实现精准水稻种植具有重大意义。在上海市农工商现代化农业园区“精准农业试验与示范基地”开展的水稻精准种植试验 ,结果与其他地块相比较 ,化肥使用量减少 1 5 % ,单产提高 8% ,总收益提高 1 8%。精准水稻种植信息系统是实现水稻精准种植的核心 ,目前完成 PRC/ INFO1 .0版本的开发 ,本文介绍了系统的结构。
Precision agriculture is one direction of the world agricultural development in the new century and also is the case in China Precision agriculture in China is in the initial stage Rice yield amounts to about 40% of the total output of grain in China It is of great significance for better utilization of agricultural resource and environmental protection if the precision rice cultiv ation is realized The experimentation of precision rice cultivation has been carried out in experimental and demonstrated base of precision agriculture on Wusi Farm in Fengxian County of Shanghai The experimentation has got the support from Chinese Academy of Sciences, Shanghai Agriculture, Industry & Commerce General Corp and Shangh ai Meteorology Bureau The experimental results show that the applied chemical fertilizer decreased by 15%, per unit area yield of rice increased by 8%,and the total income increased by 18% compared with paddy fields without practising precision cultivation Information system for precision rice cultivation (PRC/INFO) is the kernel for realizing precision rice cultivation PRC/INFO 1 0 is finished by now The software modules included the following: (1) management of database; (2) conversion, management and analysis of paddyfield spatial data; (3) decision making of paddyfield management and fertilization; (4) economic evaluation of precisionrice cultivation; and (5) visual output of fertilization plan The module of paddy field spatial data management among the system is only based on SupperMap 3 0, ot hers are developed by ourselves This paper introduces construction, flow progress, main function and technol ogical characteristics of the system The system was only used in experimental filed of Shanghai by now It should be improved step by step
