摘要
精确农业是超前性的农业新技术 ,它是根据作物、土壤和病虫害的时空变量 ,应用全球定位系统 (GPS)、遥感 (RS)、地理信息系统 (GIS)、变率处理技术 (VRT)和决策支持系统 (DSS)等进行田间耕作和管理和一种“处方农业”。经济发达国家已开始推广精确农业 ,发展中国家也开始了广泛的应用研究和实验示范。我国发展精确农业有诸多限制因素 ,但近期可重点发展节水、节肥精确农业 ,在农业发展较快的地区可发展精确设施农业。
Precision agriculture is one of the most advanced technologies which applies GPS?RS?GIS?VRT?DSS to farming practices and field management based on temporal and spatial variabilities of crops,soils,insect,pest and disease.The developed countries have mainly spreaded the technology of precision agriculture and many developing countries have evolved in the application studies and experimental demonstration.Because of many limitations,China should develop the technological system of watersaving and fertilizersaving precision agriculture in the near future.The precision equipped agriculture can be implimented firstly in the region where the equipped agriculture has been developed fast.
