The invention discloses a method for performing cotton chemical defoliation by using an agricultural unmanned aerial vehicle, and belongs to the technical field of agriculture. The invention discloses a method for carrying out chemical defoliation on cotton by utilizing an agricultural unmanned aerial vehicle. The method comprises the following steps: spraying a liquid medicine 18-25 days before harvesting; the liquid medicine is prepared from a defoliating agent, ethephon, a special auxiliary agent for flight control and water; in the spraying operation process, the agricultural unmanned aerial vehicle works according to the selected flight parameters and the set route. The agricultural unmanned aerial vehicle is used for chemical defoliation, aerial spraying operation is achieved, manual row division is not needed, cotton plants are not damaged, operation is accurate, and the situation of repeated spraying can be avoided through the function of full-autonomous operation; meanwhile, the high-pressure/centrifugal spray head sprays liquid medicine fog drops with small particle size, the coverage area of the liquid medicine is large, the uniformity of the liquid medicine is good, the fog drop penetrability is increased by downward airflow generated by a rotor wing of the high-pressure/centrifugal spray head, compared with locomotive defoliation, water and medicine are saved, the spraying process is accurate, efficient and cost-saving, and meanwhile, the cottonseed yield is increased.

    本发明公开了一种利用农业无人机进行棉花化学脱叶的方法,属于农业技术领域。本发明公开的一种利用农业无人机进行棉花化学脱叶的方法,在采收前18‑25天喷施药液;药液由脱叶剂、乙烯利、飞防专用助剂和水组成;喷施作业过程中,农业无人机按照选择的飞行参数和既定的航线进行作业。本发明利用农业无人机化学脱叶,是空中喷施作业,无需人工分行、不伤棉株、作业精准,全自主作业的功能可避免重复喷药的情况;同时高压/离心式喷头喷施药液雾滴粒径小,药液的覆盖面积大且均匀性好,其旋翼产生的向下气流增加了雾滴穿透性,与机车脱叶相比节水、节药,可实现喷施过程精准、高效、节本,同时提高棉籽产量。
