Technical Advantages Of Agricultural Drones: Precision Application Of KO Traditional Plant Protection

It is reported that there are three main areas of application of agricultural drones: one is remote sensing acquisition of low-altitude agricultural information, the other is agricultural aviation plant protection, and the third is auxiliary pollination for crop production. Among them, the application field is agricultural aviation plant protection.

According to statistics from the Ministry of Agriculture, there were not many agriculture UAV drones that actually did plant protection in 2015, and more were being demonstrated. Only in 2016 did agricultural drones really take on the task of agricultural plant protection operations, but the development speed is very fast.

In the field of agricultural plant protection applications, data provided by the Nanjing Institute of Agricultural Mechanization of the Ministry of Agriculture shows:

In terms of operating efficiency, the drone is 100 times as much as a manual sprayer with a manual backpack;

In terms of operation quality, the drone uses an ultra-low-volume spray method to improve the adhesion. The downwash airflow generated by the rotor blows the blades, which improves the adhesion rate of the lower part of the crop and the back of the blade. 15% ~ 35%, it has a good prevention and control effect against sudden and explosive diseases and insect pests;

In terms of operating costs, the annual revenue of spraying operations using a single-rotor oil-powered drone with a 25 kg payload and a single-rotor electric drone with a 15 kg payload is 33 times and 25 times the annual profit of a motorized sprayer, respectively; it is a manual manual spray 133 times and 93 times.

In the field of crop pollination, due to the low efficiency of artificial pollination, the workload is very large. Artificially assisted pollination, each laborer can pollinate 3 to 10 acres per day; agricultural drones are used for hybrid rice seed pollination, and the pollination rate and rice seed setting rate are better than the traditional artificial rope method, the efficiency is artificial 20 times, this method is widely used in the United States.

In the field of remote sensing, the advantages of agricultural drones are reflected in the following: one is the flexibility and high efficiency of remote sensing; the other is suitable for complex farmland environments; the third is an important supplement to fine agricultural information acquisition technology; the fourth is high spectral resolution and suitable Precision agriculture.
