新华社广州6月29日电 题：珠江两岸，低空经济"振翅高飞" 新华社记者宋晨、徐弘毅、孙文豪 在深圳市龙岗区的一处户外测试场地上，一台配备60升水箱的农业无人机缓缓升空，在到达预定高度后，一边盘旋一边向下方的草坪进行喷 洒作业。 这台正在演示的"Q100"农业无人机来自深圳联合飞机科技有限公司，目前已在国内多地投入使用，并出口东南亚等国际市场。 参加"活力中国调研行"主题采访活动的记者们看着无人机的演示纷纷感慨：科技创新正让人们的生产生活更加便捷。 "Q100"农业无人机在进行演示。新华社记者 宋晨 摄 2023年研制这款农业无人机时，该公司工业设计师唐安澜和同事深入东北、安徽、广东等地农村考察，详细记下田间地头的实际需求。他发 现，南方丘陵地区与东北平原在道路宽度、种植规模和运载无人机的交通工具等方面都有所区别。 "在平原地区，不少农民用皮卡货车搬运无人机，而丘陵地区的农户则多用小型三轮车运无人机，我们据此调整了无人机尺寸。"唐安澜说， 针对南方多山地区，无人机安装了适应山地起伏的防避雷达，保证飞行安全。目前，农业无人机可以适应不同地形和种植需求，适用于喷洒、播 撒、运输、航测等多种作业任务。 走进广东空天科 ...
