Overview of Precision Agriculture Aviation Technology
摘要
Modern technologies and information tools can be used to maximize agricultural aviation productivity allowing for precision application of agrochemical products. This chapter reviews and summarizes the state-of-the-art in precision agricultural (PA) aviation technology highlighting remote sensing (RS), aerial spraying, and ground verification technologies (GVTs). Further, the authors forecast the future of precision agricultural aviation (PAA) technology with key development directions in precision agricultural aviation technologies (PAATs), such as real-time image processing, variable-rate (VR) spraying, multisensor data fusion and real-time kinematic (RTK) differential positioning, and other supporting technologies for unmanned aerial vehicle (UAV)-based aerial spraying. This review is expected to provide references for peers by summarizing the history and achievements, and encourage further development of precision agricultural aviation technologies. The increase in intensive agriculture stimulated by the need to feed a growing global population has relied on the use of chemical pesticides as the first line of defense in crop protection programs. The use of pesticides is an integral part of modern agriculture and contributes to the productivity and quality of the cultivated crop. It is estimated that the use of agrochemicals prevents a loss of up to 45% of the world’s food supply. However, there are continuing concerns from national governments and the general public surrounding the potential adverse effects of pesticides. This includes the environmental impact and risks to human health during application in the field and from residues remaining in the food chain. As a result, there are now important policy drivers strengthening the management of agricultural non-point source pollution and the promotion of low-toxicity and low-residue pesticides. The Ministry of Agriculture of China also passed a reduction program for chemical fertilizers and pesticides, requiring a net zero growth in chemical fertilizer and pesticide applications by 2020. The main goal of agricultural aviation operations is the efficient and effective application of chemical fertilizers and pesticides. Precision agricultural aviation (PAA) technologies (PAAT) have rapidly developed in recent years attracting the attention of government departments and farm users as an effective means to reduce pesticide residues and adverse environmental impacts while enhancing pesticide effectiveness.
