美国密西西比三角洲农业航空和精准农业技术研发现状、展望与启示（英文）

Perspectives and experiences on the development and innovation of agricultural aviation and precision agriculture from the Mississippi Delta and recommendations for China

作物生产管理已经进入智慧农业阶段。智慧农业是由最先进的农业信息技术、智能装备以及大量的数据资源所驱动的先进农业科技理念。智慧农业继承了精准农业概念,把农业生产管理由机械化和信息化提高到高度自动化和智能化的农业生产管理。精准农业从上世纪八十年代的粗略监测发展到本世纪10年代的详细监测和控制。在精准农业的发展过程中,农业航空在作物保护和肥料施用方面起到了关键的作用。而在作物保护和肥料精准施用方面,基于全球导航产生的带有空间信息遥感数据配方图是至关重要的。随着现代化农业的发展,农业航空会因更有效的土壤和植物健康监测和更加快速的机电系统响应,在推进精准农业实际应用上显得越发重要。本文具体从美国最重要的农业地区之一密西西比三角洲出发,总体介绍了农业航空在精准农业向智慧农业迈进过程中的状况。重点介绍了美国农业部在密西西比三角洲地区在航空应用技术和低空遥感方面的研发工作;为发展新一代精准农业和智慧农业,进一步研发农业航空技术的问题、挑战和机会进行了讨论;最后提出了中国发展智慧农业建议。

Crop production management has advanced into the stage of smart agriculture,which is driven by state-ofthe-art agricultural information technology,intelligent equipment and massive data resources.Smart agriculture inherits ideas from precision agriculture and brings agricultural production and management from mechanization and informalization to intelligentization with automatization.Precision agriculture has been developed from strategic monitoring operations in the 1980s to tactical monitoring and control operations in the 2010s.In its development,agricultural aviation has played a key role in serving systems for spray application of crop protection and production materials for precision agriculture with the guidance of global navigation through geospatial prescription mapping derived from remotely-sensed data.With the development of modernized agriculture,agricultural aviation is even more important for advancing precision agricultural practices with more efficient soil and plant health sensing and more prompt and effective system actuation and action.This paper overviews the status of agricultural aviation for precision agriculture to move toward smart agriculture,especially in the Mississippi Delta region,one of the most important agricultural areas in the U.S.The research and development by scientists associated with the Mississippi Delta region are reported.The issues,challenges and opportunities are identified and discussed for further research and development of agricultural aviation technology for next-generation precision agriculture and smart agriculture.
