As a large agricultural country, China has 1.8 billion mu of basic farmland, and a large number of people are required to engage in agricultural operations every year. With the advancement of science and technology and the development of agriculture, plant protection drones have gradually entered the public's field of vision, effectively improving the efficiency of agricultural operations and It solves the problems of various social status quo, and has received more and more unanimous praise. So what kind of plant protection drone can be said to have a good operating effect? Whether the pesticide itself is of high quality, and whether the pesticide suitable for flying defense is used directly affects the operating effect. In addition, the pesticide application history, pesticide resistance, temperature, soil and other growth environments of crops and the time of pesticide application all have a greater impact. In addition, generally speaking, MANHOPE and everyone determine the important factors of the quality of plant protection drones from the following four aspects.
Can it spray accurately and hit the pesticide in place?
What is to apply pesticides in place? It means that in the process of plant protection, pesticides should be sprayed on the front and back of crop leaves, and the drugs should be attached to the leaves in order to effectively kill pests. Whether the plant protection drone can hit the pesticide in place depends on the pressure wind field and the atomization effect. Spraying with traditional sprayers often fails to reach the back of the leaves of the crops. The plant protection drone uses the rotation of the motor to make the propeller generate lift and bring a strong downpressure wind field, which can blow the blade over, so that the medicine can be attached to the back of the blade. But sometimes the wind field is too large, which will cause waste of medicine and damage to crops.
Can it be sprayed evenly so that the target area is evenly sprayed?
At present, the plant protection drones on the market mainly have two spraying technologies, one is constant spraying technology, and the other is variable spraying technology.
The plant protection drone needs to turn when flying in the field, and it will generally slow down when turning. If it is a constant spraying technology, the flow rate will not be automatically adjusted as the flight speed slows down, which may cause excessive spraying of crops at the turning point of the field , will produce phytotoxicity and waste pesticides. The plant protection UAV adopts variable spraying technology, and the flow rate can be reduced as the flight speed slows down, so as to ensure that the amount of pesticide applied to each inch of farmland is equal and achieve a good spraying effect.
Can re-spraying and leaking be avoided?
Heavy spraying and missed spraying will cause great damage to crops, especially chemical control agents such as herbicides. Spraying too much will cause phytotoxicity, and spraying too little will have no effect. To avoid heavy spraying and missed spraying, it is necessary for the plant protection drone to be able to achieve high-precision flight.
Can it adapt to various terrains?
Some farmlands have uneven surfaces, or some crop canopies have different heights. To ensure the spraying effect, plant protection drones need to be able to adapt to various terrains and maintain a relatively constant distance from the crop canopy. At present, plant protection drones can achieve this through ground imitation flight technology. Plant protection UAVs that cannot fly in imitation of the ground, when operating on uneven crop canopies, short-crown crops may have poor pesticide application effect due to the distance from the UAV. In addition, the height change of the terrain, especially the elevation, may cause the drone to collide and break.
The above are the four important factors that determine the quality of plant protection drones learned by MANHOPE and everyone today. They are whether it is sprayed accurately, whether it can hit the pesticide in place, whether it can be sprayed evenly, so that the target area can be evenly sprayed, and whether it can avoid heavy spray leakage. Spray and can adapt to a variety of terrain.
