With the development of intelligent, unmanned and intensive agriculture, spring ploughing in the field will be more time-saving and labor-saving? Black technology? Insert the wings of science and technology for agriculture. As a large agricultural country with 65.438+0.8 billion mu of basic farmland, China needs a large number of agricultural plant protection operations every year. There are 654.38+ten thousand people suffering from pesticide poisoning every year in China, and the mortality rate is about 20%.

There is no official statistics on the number of deaths caused by pesticide residues and pollution, which must be an amazing number. Plant protection drone service agriculture has developed rapidly in developed countries such as Japan and the United States. 1990, Yamaha Corporation of Japan took the lead in launching the world's first unmanned aerial vehicle, which was mainly used for spraying pesticides. Pesticide spraying was used for the first time in rice growing areas in southern China. 20 16 agricultural plant protection drone has gradually become the new favorite of the industry, and there are cases of using drone plant protection everywhere. According to the latest statistics of the Ministry of Agriculture, as of June 5, 20 16, there were more than 300 enterprises producing professional-grade UAVs nationwide, including more than 200 enterprises producing plant protection UAVs, producing all kinds of plant protection UAVs 178 varieties, with the number exceeding 5,000. Unmanned small helicopter has the advantages of low working height, small drift, hovering in the air and no need for special take-off and landing airport. The downward airflow generated by the rotor is helpful to increase the penetration of fog flow to crops, with high control effect, remote control operation, avoiding spraying workers from contacting pesticides and improving spraying safety.

In addition, the spraying technology of electric unmanned helicopter can save at least 50% pesticide consumption and 90% water consumption, which will greatly reduce the resource cost. Drone spraying greatly reduces the contact risk caused by crowd gathering. Compared with the oil-powered UAV, the electric UAV has smaller overall size, lighter weight, lower depreciation rate, lower labor cost per unit operation and easier maintenance. In addition to learning how to operate plant protection drones, we must also master the corresponding knowledge of agriculture, pesticides and plant protection. Different crops have different dosage of liquid medicine, different requirements for concentration ratio, and different requirements for machine performance and accuracy.
