空から？地上から？ドローンとスプレーヤー徹底対決！！【DJI agrasT50】

Summary

In this video, Saori compares the efficiency and ease of using agricultural drones versus traditional sprayers for pesticide and fertilizer application. By conducting an experiment on a wheat field, Saori highlights the significant time-saving benefits of drones, reducing spraying time by about 20 minutes compared to sprayers. Drones are also praised for their accuracy and minimal environmental impact, as they avoid trampling crops. The video emphasizes the advantages of drones, such as reduced physical effort and streamlined operation, while acknowledging the unique benefits of sprayers for larger fields. Saori concludes by encouraging viewers to explore drone technology further.

Takeaways

• 😀 The DJI Agras T50 agricultural drone is introduced as a new tool for pest control and fertilizer spraying.
• 😀 The T50 drone has a large wingspan of about 3 meters when extended, making it significantly larger than other agricultural drones.
• 😀 The drone is designed to spray fertilizers or pesticides from the sky, offering a more efficient alternative to traditional sprayers.
• 😀 The comparison experiment between the drone and a conventional tractor sprayer shows differences in efficiency and time taken.
• 😀 The tractor sprayer, although effective, takes about 50 minutes for pest control on a field of 2 hectares.
• 😀 The agricultural drone, on the other hand, completes the same task in approximately 30 minutes, saving around 20 minutes of time.
• 😀 The drone operates with a GPS system that allows for precise spraying and minimizes human error during operation.
• 😀 Spraying with a drone requires much less water compared to traditional sprayers, as it uses concentrated pesticides spread over a larger area with less liquid.
• 😀 The drone can automatically disperse pesticides by pressing a single button, reducing the physical and mental load on the operator.
• 😀 The experiment reveals that drones are especially beneficial in reducing time and effort when compared to the manual operation of a traditional sprayer.
• 😀 In conclusion, both drones and sprayers have unique advantages, but drones provide a significant advantage in terms of time, ease of use, and reducing operator strain.

Q & A

What are the main objectives of the experiment discussed in the script?

The main objectives of the experiment are to compare the efficiency of agricultural drones (specifically the DJI Agras T50 model) and conventional sprayers in pest control and fertilizer application, with a focus on time efficiency and ease of use.

How is the DJI Agras T50 agricultural drone different from traditional sprayers?

The DJI Agras T50 drone is designed to spray pesticides and fertilizers from the air, offering pinpoint accuracy with a smaller spray volume, while traditional sprayers operate on the ground and cover wider areas but require more manual effort and a larger water volume.

What is the size and capacity of the DJI Agras T50 drone?

The DJI Agras T50 drone has a wingspan of about 3 meters when fully spread out and weighs approximately 40 kg. It is designed for aerial pesticide and fertilizer spraying.

How long did it take for the sprayer to complete the spraying of 2 hectares?

The sprayer took about 50 minutes to complete the spraying of 2 hectares, including the time for setup, preparation, and the actual spraying process.

What was the time difference between the drone and the sprayer for spraying 2 hectares?

The drone completed the spraying of 2 hectares in about 30 minutes, which was 20 minutes faster than the sprayer, which took about 50 minutes.

What are some of the key advantages of using drones for agricultural spraying?

Drones offer several advantages, including reduced time and physical effort required, precise application of pesticides and fertilizers, and the ability to avoid trampling crops. They also have the convenience of automatic operation, requiring only a button press to start.

What challenges were encountered during the preparation of the sprayer?

Some challenges during the sprayer preparation included difficulty opening the medicine lid and managing the water and pesticide mixing process, which took approximately 15 minutes due to these issues.

How does the drone's spray application differ in terms of water usage compared to the sprayer?

The drone uses significantly less water, with a dilution ratio of 1 liter of pesticide per hectare mixed with 7 liters of water, compared to the sprayer's 1 liter of pesticide per hectare mixed with 1000 liters of water.

Why is the sprayer's lack of GPS considered a disadvantage in the script?

The sprayer lacks GPS, which makes it harder to spray accurately and efficiently, requiring the operator to carefully monitor the spraying process and adjust the path, leading to a more hectic and manual operation.

What was the role of the 'tilt' medicine in the experiment?

The 'tilt' medicine was used to prevent wheat from turning black, with both the sprayer and drone using the same amount of medicine (1 liter per hectare) during the experiment to compare efficiency.
