The hottest unmanned helicopter in the development

  • Detail

Prospects for the application of unmanned helicopters in the development of China's agriculture and forestry industry and the prevention and control of diseases and pests

the current problem of agriculture and forestry production in the development of the national economy is that in addition to the prominent position and significance of insiders, the development of agriculture and forestry production is a top priority related to the national economy and the people's livelihood. At present, diseases and pests are still the natural enemies of China's development of agricultural production. The annual losses caused by diseases and pests are very huge, and the cost of prevention and control is also very considerable

plant pest control is a long-term task. At present, China mainly relies on chemical control. The control effect of chemical pesticides is not only restricted by the nature and performance of the agent itself, but also affected by the timing of application, technical quality and medical equipment. At present, there are many problems and difficulties in the prevention and control of conventional drugs and instruments in China due to different regional environmental conditions:

first, the occurrence of pests and diseases is time-dependent, especially feeding or boring pests, such as locusts, jujube geometrids, slime worms, heartworms, etc., which must be treated in a short time to eliminate them in the larval stage. However, the speed of spraying pesticides manually is slow and the effect is poor

second, the particularity of the position where diseases and pests occur. Because the habits of diseases and pests are to inhabit the back of stems and leaves, the cracks of warped skin, branches and back, and spray the artificial spray machine liquid only on the front of the peripheral branches and leaves, the effect cannot be exerted normally, but it is easy to make diseases and pests resistant to drugs

third, the plant surface is not easy to be attached with chemicals. Because the plant surface has smooth wax skin layer or linear hair (seta), it is very difficult to form a "drug film" by spraying large droplets on the plant surface, so that diseases and pests will have opportunities

fourth, the prevention and control of plant diseases and pests in mountainous areas. Due to the complex terrain and rugged roads in mountainous areas, it is difficult to use water. Once diseases and pests occur, it is difficult to control them. Even the use of conventional spray machine is a drop in the bucket, and it is difficult to achieve timely prevention and control

fifth, it is particularly difficult to prevent and control in forest areas. Due to the wide forest area, tall and dense trees, it is very difficult to prevent and control manually

sixth, the quality of artificial spraying is poor, the speed is slow, and the labor intensity is high. It is difficult to spray the liquid medicine evenly with a hand-held spray gun, which can not play the role of disease treatment and pest elimination

therefore, the selection of small unmanned helicopters for agricultural and forestry production and pest control is the only way for China's agricultural development. It has the advantages of low cost, high efficiency, fast speed and good effect, and can overcome all the disadvantages brought by manual prevention and control, so as to achieve twice the result with half the effort. In particular, low altitude remote sensing technology can achieve early monitoring, early prevention and control, and eliminate all pests and diseases in the bud. We can really cure the early, the small and the late. It not only saves medicine, time and labor, but also reduces disaster losses. In addition, it can also be equipped with ordinary computers to a minimum. Moreover, it can greatly improve work efficiency and reduce the harm of pesticides to personnel and environmental pollution

with the development of aviation technology, the technology and application of unmanned helicopters are becoming more and more mature. In particular, agricultural unmanned helicopters are quite common in developed countries such as the United States and Japan. According to relevant data, Yamaha Rmax series alone has more than 1200 unmanned helicopters currently used in agriculture and forestry in Japan, with more than 6500 controllers. In Japan, this kind of unmanned helicopter can sow, cultivate, fertilize, spray pesticides, prevent and control pests and diseases. Yamaha Rmax unmanned helicopter can spray pesticides by 7-10 hectares per hour, and one Rmax can spray pesticides by 80 hectares per day. One hectare of paddy field uses 7 liters of pesticide per liter of water

according to the statistics over the years, at present, the planting area of crops in China is as follows:

(I) the total area of agricultural cultivated land: hectares

1. The area of grain crops: hectares of grain, hectares of beans, hectares of potatoes

2. Oil plants: hectares

3. Cotton: hectares

4. Hemp: 376000 hectares

5. Sugar: hectares

6. Tobacco: hectares

7. Medicinal materials: 278750 hectares

8. Vegetables: hectares

9. Others: hectares

(II) grassland and grassland area:

1. Grassland Slope hectares

2. Grassland hectares

(III) occurrence and prevention area of various disasters

1 Occurrence area of diseases and pests: hectares

prevention and control area: hectares

2. Occurrence area of rat pests: hectares

prevention and control area: hectares

3. Occurrence area of farmland grass pests: hectares

prevention and control [automobile manufacturers] in the concept car, the elements used in the concept car will not all produce infiltration effect area: hectares

domestic crop areas with perennial diseases and pests: rice area, wheat area, cotton area, rape area, sugarcane area Sugar beet area, tea tree area, test tobacco area, etc

sudden pest areas: aphids, grassland grasshoppers, rice planthoppers, leafhoppers, etc. in Xinjiang cotton area

explosive pest areas: locusts, wheat rust, etc

in view of the above, we believe that unmanned helicopters have an extremely broad market and application prospect in China's future agricultural and forestry development. (end)
