【摘要】 作物倒伏是影响农作物产量、造成农业经济损失的一大主要原因。有效地监测农作物倒伏情况,并对作物损失进行预评估,能够为农民和有关部门的灾后防控提供有效的数据支持。运用灵便小巧的无人机平台对作物倒伏区进行监测,可有效避免人工监测引起作物二次倒伏现象的发生。本文针对国内外关于典型倒伏农作物研究种类单一、监测方法集中的现状,以及运用无人机平台提取处理作物倒伏信息所面临的续航时间短、智能化自动化水平有待提高、混种作物监测精准度低、农户专业技能水平普遍偏低等问题进行系统的分析研究;同时,对基于无人机平台监测其他农作物倒伏状况进行展望,提出无人机倒伏监测的高效智能化、识别精准化、监测普适化、功能人性化、性能完备化发展,为拓展无人机平台在各类直立农作物倒伏现象中的研究应用提供参考。更多还原

【Abstract】 Mower is one of the earliest animal husbandry machines in human production and use, and it is also indispensable key equipment for forage harvesting. Based on the summary and research of the working principle, cutting technology and driving device of the forage mower in China, the development course of the mower at home and abroad is described. Combined with the performance and characteristics of the typical forage mower products at home and abroad, the analysis and comparison of different types of forage mowers are carried out, and it is concluded that the overall level of forage mowing mechanization in China is still certain compared with that in developed countries There are some problems and deficiencies, such as single product variety, low automation, unstable technical performance and poor reliability. It is proposed that the forage mower will develop towards the direction of variety diversification, high efficiency, large-scale, reliable performance, excellent manufacturing, control automation and intelligence in the future, in order to provide reference for further research and development of forage mowing machinery in China.更多还原
