Rice is the second largest food crop in my country with a planting area of 3.06 million hm2 and a self-sufficiency rate of over 99%. However, due to the scattered land, the average planting area per household is only about 1.15 hm2. The planting, transplanting and harvesting of rice have been mechanized to improve work efficiency. However, the chemical control equipment for rice is outdated and still stays in the manual control stage, which not only causes artificial waste, but also misses the best control period if the control is not in time.
With the industrialization of rice planting, the development of medical equipment has become a new problem restricting the control of rice diseases and insect pests. Because it is difficult for land machinery to work in the field during the rice growth process, conventional spraying is labor intensive, and it is difficult to reach the middle and lower parts of the rice, and the operation efficiency is low, and it is also easy to cause harm to the pesticide application personnel and the environment. In view of this, plant protection drones are popular due to their advantages such as low dosage, precise operation, and low labor intensity. They can achieve mechanized, professional, and integrated control of rice pests and diseases.
