With the improvement of agricultural automation, the use of agricultural spraying drones in large-scale farms has increased year by year in recent years. So what are the advantages and disadvantages of agricultural spraying drones?
First, let's talk about the advantages of agricultural drones:
The first advantage is that agricultural drones are highly efficient, saving time and labor. The speed of the drone spraying is fast, and it can complete the artificial one-day spraying in tens of minutes. For example, to complete the spraying of 1 hectare of corn field, it takes almost a day to spray the spray manually, while the drone can complete it in 20 minutes. Especially when there are severe pests and diseases on crops, the use of drones to spray medicine can be prevented in a timely manner.
The second advantage is that the degree of atomization is high, and the spray is very uniform. The nozzles of agricultural drones are generally ultra-fine atomizing nozzles, so the degree of atomization is high. At the same time, its flight speed is basically uniform, so the spray is relatively uniform, which can improve the control effect of crop diseases and insect pests.
The third advantage is less restricted. Whether it is fruit trees, or wheat, corn and other field crops, as long as there are no obstacles around the flight, such as telephone poles, wires, tall trees, etc., the drone can successfully complete the spraying operation. For example, spraying pesticides on fruit trees is not as convenient as drones. If rust occurs on a large scale in the late stage of corn growth, because the corn plant is very high, it is very inconvenient to manually spray medicine at this time. Using drones, it is very convenient and efficient to control.
The fourth advantage is to save water and medicine. An ordinary electric sprayer, to manually complete the spraying of 1 hectare of crops, requires 400 kg of water. The drone completes 1 hectare and only needs 20kg of water. The dosage of the drug, in sunny and windless weather, the dosage of the drone is 1/2 or 2/3 of the sprayer.
shortcoming:
The first disadvantage is that it cannot be penetrated, that is, the drone sprays pesticides on the leaves of crops facing the sky, but the leaves on the back cannot be sprayed. This is also the biggest disadvantage of drone spraying. For example, many diseases and insect pests on wheat, such as aphids and rust, are not only found on the upper part, but also in the middle and lower parts. Although the drone sprays evenly, it often fails to hit the middle and lower parts of the wheat seedlings, let alone the control of the rhizomes, which will reduce the effect of pest control on wheat. If the concentration is increased arbitrarily, it is very likely to cause drug damage.
The second disadvantage is that drones spray are easy to drift when spraying medicine. Because the agri drone is a flying operation, if it is sunny and windless, it is fine. If it is a little windy, there may be uneven spraying, more medicine in some places, less medicine in some places, or even missing spray. If it drifts to surrounding crops, it is likely to cause phytotoxicity.
The third disadvantage is the high overall cost. Whether buying or maintaining a drone, the cost is not low. A drone with better quality is expensive, a little damaged, and the maintenance cost is also high.
Therefore, although drones have many advantages, there are still many disadvantages. Whether to use them depends on individual needs.
