<b>中心接受中国国际电视台关于“Drone spraying”的专题采访</b>
2018年3月8日，国家精准农业航空施药技术国际联合研究中心团队成员就筹划已久的海南热区飞防试验在海南澄迈展开，试验共进行七天。团队在试验期间（2018年3月11日）接受了专程从北京赶来的中国国际电视台（英文简称CGTN，别称中国环球电视网）记者的专题采访。采访内容主要针对我国目前的飞防现状及团队科研进展现状、团队在全国各地的试验状况及对下一步进行相关工作的规划。
本次采访是在热区飞防试验期间实地进行，试验对象主要是槟榔树。参与飞防试验的企业单位有海南农飞客科技有限公司、安阳全丰生物科技有限公司、海南中农航服科技有限公司、海南惠飞科技有限公司及海南标普农业科技有限公司。参与飞防试验的机型有油动单旋翼、电动多旋翼等。各种无人机机型均在作业状态时接受了媒体采访，本次飞防作业作物涵盖了槟榔、冬瓜及辣椒等，采访主要包括三大模块。
首先，媒体记者在田间针对无人机将施药与传统人工施药进行了对比，实地调研后发现无人机施药不仅省时省力、在减药减施同时又大大提高作业效率，保护了作业人员等人身安全。
其次，媒体工作人员深入到试验田里，拍摄无人机作业时到药液喷洒实况，并对团队试验方案及试验目的等进行了采访。本次试验测试主要包括三个方面：槟榔树冠层药物沉积、地面药液流失及药液飘移等。
最后，媒体记者对本次试验方案的主要制定人—博士生王娟进行了专题采访。采访内容主要包括目前我国的农药应用现状、无人机施药技术现状、无人机作业标准、无人机未来发展趋势等。（附：CGTN电视台采访对话）本次采访于2018年3月27日在CGTN电视台 “Global Watch”频段播出。
中国中央电视台是已筹备的新国际传播机构，成立于2016年12月31日。该机构包括6个电视频道、3个海外分台、1个视频通讯社和新媒体集群，以丰富的内容和专业的品质为全球受众提供良好的服务。相信本次报道能够使国际上更多的人们了解到无人机施药在中国的应用及我团队在此方面所做的研究。
（ Drone spraying: The future of China’s agricultural modernization
Over 1.8 million tons of agricultural pesticides were used in China in 2016, accounting for one-third of the world’s total amount. As the world’s top consumer of pesticide, China is, at the same time, the leading manufacturer of drones. Now a group of people in southern China is striving to use drones to reduce the country’s consumption of pesticides. Deng Jiajian, general manager of Hainan Nongfeike Agricultural Technology Corporation, has the largest agriculture drone fleet in the country’s southern tropical island province. He told CGTN that using drones to spray pesticides is 30 times more efficient than the traditional way. And through a great number of experiments, Deng has found that drone spraying can save 25 percent of pesticide usage. For each drone to carry out its task, it only takes two liters of water per acre in China, compared to 60 liters of water with manual spraying.36-year-old Wang Juan is a postdoctoral fellow at the South China Agricultural University. She and her team have been studying precision agricultural aviation pesticide spraying technology since 2014.Wang Juan said their target is to achieve precise spraying. “First, we use spectral cameras installed on the drone to scan farmland and generate a prescription picture that can show the different levels of insect damage to the farmland. Then the drone can control the amount of pesticides sprayed on the crops according to their damage levels.”To this end, a huge amount of detailed work needs to be carried out. Wang and the students have to fly all over the country to carry out experiments on different crops, and collect raw data piece by piece. According to Wang, aviation spraying is a very mature concept in the US but a new thing in China. So the industry in China doesn’t have an operation standard. What’s more complicated is that the standard for each crop in each stage of growth is different. “So we’re now trying to establish a standard model for China’s drone spraying,” she added. Currently, there are nearly 5,000 agricultural drones in China, and the number is rapidly increasing with big manufacturers like DJI joining the arena. Wang hopes the government can introduce more preferential policies to support the development of agricultural drones. ）
