With the development of agricultural mechanization, unmanned plant protection machines can show their talents. Compared with traditional plant protection methods, agricultural drones have the advantages of efficient automation, high safety, good prevention and control effects, saving resources, and reducing operating costs. However, my country's agricultural drone market is still in its infancy. According to relevant data, my country's agricultural drones only account for 1.67% of the total plant protection operations, far below the level of developed countries such as the United States and Japan.

The heavy status quo of traditional agriculture has induced the birth of drones

1. The spraying equipment is backward, and the waste of pesticides is serious

Most farmers in China still use manual knapsack sprayers, and the effective utilization rate of pesticides is very low. According to the data, the effective adhesion rate of pesticides can only reach about 15% when the spraying method is appropriate using this kind of medicine device, and the effective adhesion rate of pesticides is generally less than 10%. This means that a large amount of liquid medicine is wasted and lost to soil, water and air. Studies have shown that among the waste pesticides, 40%-60% of the chemical liquid directly flows into the soil, and 5%-30% of the chemical liquid diffuses into the air in the form of extremely fine mist droplets and becomes a floating state, which is also harmful to the environment. caused serious pollution.

2. "Opium treatment" caused serious pesticide residues exceeding the standard

Due to the backward spraying technology, large-volume coarse droplet spraying, low utilization rate of pesticides and poor control effect, farmers have to use pesticides to repeatedly spray in order to kill insects, thus forming a vicious circle of "opium treatment". Insects have been soaked in "medicine jars" since childhood, and crops have also been fed by "medicine" since childhood, so there is no doubt that pesticide residues exceed the standard.

In order for my country's agricultural products to enter the international market, they must meet a number of international indicators, among which pesticide residues are an important indicator. At present, based on self-determined standards, the average rate of grain pesticides exceeding the standard in my country is 6.2%. Therefore, the problem of pesticide residues in agricultural products has become one of the important obstacles for my country's agricultural products to enter the international market. According to statistics, my country's annual export of 7.4 billion US dollars is adversely affected by this.

3. Productive poisoning often occurs

Chinese farmers use the most backward way to spray pesticides. The pesticide water is sprayed on the crops, and the sprayer has to walk through the crops. Therefore, it may only take a few minutes for the clothes to be soaked with the pesticide water, and the atomization degree of the sprayer is poor. The problem of "running, running, dripping and leaking" is serious, and the liquid medicine can easily flow to the applicator. At the same time, the pesticide water floats in front of the eyes, especially during the peak period of pesticide use from June to September, due to the hot weather, the clothes are thin , productive poisoning often occurs. 4. Structural shortage of labor force and demand for advanced agricultural machinery due to land transfer

As a large number of rural laborers migrate to cities to work, the labor force engaged in agricultural production in rural areas continues to decrease, which naturally pushes up the labor cost of agricultural production. In addition, the working hours of migrant workers in cities is higher than that in rural areas, making agricultural production unattractive. Farmers have to increase labor costs to carry out agricultural production, but even so, when pests and diseases break out in large areas, farmers will still face the dilemma of not being able to hire people.

Rural land transfer is accelerating, and there are more and more family farms and large planters, and the demand for pest and disease control is growing. Traditional knapsack sprayers are difficult to meet the needs of large-scale and sudden pest and disease control.

Agricultural pest control drone company can provide a completely modern solution to the above problems. Using drones for spray application saves time, effort and medicine (a plant protection drone can cover thousands of acres of land a day, saving 40% of medicine, 90% of water, and 50 times the efficiency of manual work), especially in continuous In the process of using on a large-scale farm, it can prevent and control diseases and insect pests in a timely and efficient manner.

At the same time, when the drone is used for spraying operations, when the liquid droplets are sprayed from the sprayer, they are accelerated by the downward pressure wind field of the rotor to form an aerosol flow, which directly increases the penetration of the liquid droplets to the crops and improves the The deposition and coverage of the liquid medicine on the target crops can reduce the "medicine" and "water" and improve the treatment effect.

Due to the use of remote control, the poisoning caused by manual exposure to pesticides for a long time is reduced. In addition, in the context of the structural shortage of young and middle-aged labor and the continuous increase in agricultural labor costs, the development of agricultural apple tree drone sprayer must play an important role in the stable development of agriculture.

Advantages of agricultural drones

1. Autonomous operation of flight control and navigation

Plant protection citrus tree drone sprayer can use long-distance remote control operation and flight control navigation to operate autonomously. Autonomous flight only needs to collect GPS information of crops in the farmland before spraying operations, and plan the route and input it to the internal control of the ground station. In the system, the ground station gives instructions to the aircraft, and the aircraft can carry the spraying device, complete the spraying operation autonomously, and automatically fly back to the take-off point after completion.

While the aircraft is spraying, the progress of the spraying operation can be observed in real time through the display interface of the ground station. (The current agricultural drone automatic navigation operation can realize automatic fault alarm, automatic spraying, automatic generation of flight trajectory, 3D naked eye obstacle avoidance, one-key take-off and one-key landing of agricultural aircraft operation flight control and navigation system for continuous spraying at breakpoints)

2. High coverage density and good control effect

The higher and more uniform the coverage density of the atomized liquid medicine per unit area, the better the control effect.

The droplet drift test of the medicinal liquid reflects an advantage of the spraying operation of the plant protection drone on the degree of pesticide drift. When the medicinal liquid droplet is sprayed from the sprayer, it is accelerated by the downward airflow of the drone propeller to form an aerosol flow , directly increases the penetration of the droplets of the liquid medicine to the crops, reduces the degree of pesticide drift, and the deposition amount of the liquid medicine and the coverage rate of the liquid medicine are better than the conventional ones, so the control effect is better than the traditional one, and it can also prevent the pesticides from soil pollution. 4. Low cost of water saving and medicine saving

Plant protection drone spraying technology can save at least 30% of pesticide use and 90% of water consumption by spraying, which will greatly reduce resource costs. Moreover, electric plant protection drones have low depreciation rate, low energy consumption, low labor cost per unit operation, and easy maintenance.

With the application of plant protection drones in agriculture, it will fill the gap in the application field of agricultural drones in my country, and it is also a revolution in China's important agricultural unmanned machinery and technology. The application of agricultural drone technology will mark my country's agriculture has truly entered the era of high-tech agriculture.
