西北地区“精确农业”发展对策与关键技术探讨

Development trend of the precision agriculture in Northwest China

基于时空差异和按需定量管理的精确农业是21世纪农业生产的发展方向。西北地区地形相对平坦、干旱少雨、地广人稀、经济落后,具有发展精确农业的可行性和必要性;目前需要解决的关键技术是:加强农业基础学科研究与学科间的相互渗透,提高农田作业定位精度技术,加强农田基础数据库的建立与自动更新,重视新型农田机械与3S技术的集成。

Precision agriculture based on the spatial and temporal variabilities is the basic direction of agricultural production in the 21st century, which is a precise method of management according to the quantitative need. This thesis discusses the feasibility and necessity of developing precision agriculture in Northwest China. Furthermore, it analyzes the key technological problems need to be solved presently.
