The spraying drone is called a plant protection drone, also known as an unmanned aerial vehicle. As the name implies, it is an unmanned aircraft used for agricultural and forestry plant protection operations. It is composed of three parts: , navigation flight control, and spraying mechanism. The spraying operation can be realized through ground remote control or navigation flight control. It can spray chemicals, seeds, powder, etc.
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. At the same time, the labor force of young and middle-aged people in rural areas is gradually scarce, and labor costs are increasing. With the advancement of science and technology and the development of agriculture, spraying drones are gradually entering The vision of the public has effectively improved the efficiency of agricultural operations and solved various social problems, and has received more and more unanimous praise. Today, MANHOPE will talk to you about spraying drones, how to improve the efficacy of medicines and reduce costs, so that the role of drones in spraying medicines can be maximized.
1. Drug selection
Drug selection needs to consider factors such as the solubility of the drug, the concentration of the drug solution, and the mechanism of action.
The solubility of the agent should be considered. The amount of water used for spraying on the aircraft is very small. If it cannot be dissolved well, the nozzle may be blocked. It is recommended to choose emulsifiable concentrate, suspension concentrate, dry suspension, soluble powder, water agent, water emulsion, microemulsion, water Suspension concentrates, ultra-low volume sprays, etc.
The concentration of the liquid medicine is high. In this case, it is not recommended to choose high-toxicity medicine for flying defense, otherwise there will be a great risk to outsiders or crops.
The mechanism of action of the pesticide should be considered. For example, the quick-acting contact pesticides acetamiprid and nitenpyram should be selected for the control of wheat aphids that have occurred. These are pesticides with a contact killing mechanism.
If prevention is carried out in advance, it is recommended to choose thiamethoxam, etc., which are insecticides with a
systemic transmission mechanism.
For many large field growers, preventive work is often carried out in advance.

2. Dispensing
Do a mixing test in advance when dispensing the medicine, and do a good job of the second dilution of the medicine.
The water consumption of flying defense is small, and it is required that no stratification, precipitation and precipitation will occur within a period of time after a single agent is put into water.
Because every time the flying defense may be sterilized, insecticided, and nutrient agents will be sprayed at the same time. The requirement for the mixed medicinal solution is that there will be no precipitation, stratification, etc. after mixing.
3. Flight defense time
When flying defense, it is recommended to choose when the temperature is low.
Under normal circumstances, the flight defense time is generally selected before 10:00 am and after 4:00 pm.
Because the liquid sprayed by the aircraft has a high degree of atomization, it is easy to volatilize under high temperature conditions, so that the liquid cannot be sprayed to the leaves.
4. Wind force and direction
Try to choose to spray pesticides when there is no wind or low wind force, so that those crops that are sensitive to pesticides are in the upwind direction, so as to avoid waste of pesticides and cause harm to other things around.
5. With additives
Adding special additives for aerial defense can avoid the drift and volatilization of the medicine as much as possible, and can also improve the adhesion of the medicine and indirectly improve the efficacy of the medicine.
At present, there are three kinds of anti-fly additives commonly used, namely vegetable oils such as methyl ethyl vegetable oil, etc.; silicones such as agricultural silicones; polymers and so on.
Mastering the above five key steps can effectively improve the efficacy of medicines and reduce costs, so that the role of drone spraying medicines can be maximized.
