无人机在棉田管理中的应用

棉花是国内重要的经济作物和纺织工业原料,是事关国计民生的重要战略物资,但棉花生产机械化程度低,现代植棉业发展缓慢,特别是黄河流域和长江流域棉区,一家一户的棉花种植规模小、效率低。近年来,国内农用无人机产业快速发展,农用无人机技术是发展智慧农业的有效保障手段之一,它为棉花产业向机械化、智能化升级提供了一定的技术支撑。通过对农用无人机应用发展现状,及其在棉花病虫草害防控、化学调控、脱叶催熟等田间管理应用情况进行概述,提出了当前面临的主要问题和发展展望,以期为推动国内棉田无人机技术的发展和应用提供依据。

Application of Unmanned Aerial Vehicle (UAV) in Cotton Field Cultivation Management

Cotton is an important cash crop and raw material for the textile industry in China, and it is the strategic material related to national economy and people's livelihood. However, the mechanization degree of cotton production is relatively low in China and the modernization of cotton industry is still at a slow pace. Small scale cotton planting by households, which is common in the Yellow River Valley and the Yangtze River Valley cotton area, is inefficient. In recent years, as the agricultural UAV industry has developed rapidly in China, agricultural UAV technology can be used as an effective tool to promote the development of intelligent agriculture, and can also provide technical support to the upgrading of mechanization and intelligence of cotton industry. In this study, the present application status of agricultural UAV, particularly its application in field management of cotton pest control, chemical regulation, and chemical accelerated boll maturation and defoliation were summarized. In addition, main problems and development prospects of agricultural UAV were discussed, to provide certain references for the development and application of UAV technology in cotton production in China.
