Drone spraying: The future of China’s agricultural modernization

2016年中国使用的农药超过180万吨,占全球总量的三分之一。

作为全球最大的杀虫剂消费国,中国同时也是无人机的领先制造商。现在,南方一群人正在努力使用无人机来减少该国农药的消费。

海南农非可农业技术公司总经理邓家建拥有该国南部热带岛屿省份中最大的农业无人机队。

他告诉CGTN,使用无人机喷洒杀虫剂比传统方式效率高30倍。通过大量的实验,邓发现无人机喷洒可以节省25%的农药使用量。每个无人机执行任务时,中国每英亩只需要两升水,而手动喷洒的水只有60升。

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.

据王先生介绍,航空喷涂在美国是一个非常成熟的概念,但在中国是一个新事物。所以中国的这个行业没有一个操作标准。更复杂的是,每个作物在每个生长阶段的标准都是不同的。“所以我们现在正在试图为中国的无人机喷涂建立一个标准模型,”她补充道。

目前,中国有近5000台农用无人机,随着DJI等大型制造商加入,这一数字正在迅速增加。

王希望政府能够出台更多优惠政策来支持农业无人机的发展。
