According to the news report, China is a large agricultural country, with 1.8 billion mu of basic farmland, which requires a large number of personnel to engage in agricultural plant protection operations every year. In China, 100000 people are poisoned by pesticides every year. At the same time, the young and middle-aged labor force in rural areas is gradually scarce, and the labor cost is increasing; Young people are unwilling to sprinkle pesticides because they do great harm to human body. "The UAV for plant protection can be operated remotely, avoiding the risk of pesticide exposure to spraying operators, and ensuring the safety of spraying operations."

What are the main advantages of commonly used multi rotor plant protection UAVs?

① Water saving: when used in the field, the amount of water used by UAV for medicine is about 1/40 of that of traditional spray. The traditional spray uses 2-3 barrels of water per mu, about 40 liters. Take the 10 liter six rotor UAV as an example, adding 10 liters of water per flight can inject medicine into 8-10 mu of land, and more than 1 liter of water per mu is enough. When used on fruit trees, the amount of water used by UAVs for medicine is about 1/60 of that of traditional medicine. In apple and citrus areas, the amount of water used by traditional bucket spray is about 200-300 liters (400-600 jin of water) per mu of land, while the amount of water used by UAVs for fruit trees is about 4-5 liters per mu of land. The application of UAV flight defense technology has greatly saved the use of agricultural water.

② Drug saving: At present, in the field test of our actual drug use, the experimental data shows that the use of pesticides can be saved by about 30% under the premise of ensuring the control effect in most scenes (pest prevention, leaf disease, etc.); However, in some scenes where large water consumption is required, the dosage cannot be reduced, such as citrus spider, apple aphid, rice planthopper control and disease treatment.

③ Labor saving: Under the traditional drug dispensing mode in the field, it is good for one person to be able to fetch about 20 barrels of water and 10 mu of land in one day. For UAV flight defense, it only takes 10 minutes to apply drugs to 8-10 mu of land with 10 liters of water. With the average time of ground handling dispensing and field transfer, three people in a crew can apply drugs to more than 200 mu of land a day, and the average is more than 70 mu/person/day. With the help of UAVs, the efficiency of field spraying operation has been improved by nearly 7-8 times.

④ Saving money: The rent of plant protection UAV is calculated according to 8 yuan/mu of farmland and 10 mu of traditional medicine per person per day. People spend 80 yuan per day on medicine and save 1 person per day. If the saved labor can be used for other part-time jobs and the income can be more than 80 yuan/day/person, people will save money. At the same time, if 30% of pesticide usage is saved under the scenario of drug saving, even if people do not go out to work, the cost of using drones to inject drugs will be saved.
