基于问卷调查的小麦病虫草害的农户认知与无人机应用策略OA

In this study,a combination of field investigation,questionnaire survey and interview was adopted to investigate wheat cultivation,disease and pest control,and the control application status of unmanned aerial vehicle(UAV)control technologies in 5 representative major wheat-producing areas of Henan Province.Corresponding optimization strategies for the application of UAVs were proposed.The survey results showed that farmland fragmentation among farmers was relatively serious,and wheat and maize were the dominant crops.Diseases,insect pests and weeds such as spider mites(43.48%),powdery mildew(40.86%)and Galium aparine(23.81%)were predominant in the XX area.The three-level response system of"prevention,monitoring and intervention"was commonly adopted for pest control,which was characterized by low efficiency and high labor input.In total,61.90%of farmers had a general understanding of UAV technologies,while 4.76%of growers knew little about such technologies.In view of the high degree of land fragmentation,insufficient cognition and acceptance of agricultural science and technology,and the need to further improve the UAV control system,corresponding countermeasures were put forward,including integrating scattered cultivated land resources through multiple subjects such as scientific and technological demonstration households,promoting plant protection UAV technologies via multiple channels such as short videos and official WeChat accounts,and strengthening in-depth cooperation among industry-university-research entities including enterprises,universities and research institutions.This paper provides a reference for the prevention and control of wheat diseases,pests and weeds as well as the optimization of UAV application in relevant regions.
