Advantages of agriculture drone
In recent years, Farmland aviation spray has gradually introduced the agriculture drone. It has a farm manned fixed wing spray aircraft more than 140 aircraft, more than 60 helicopters, but there are still more areas are not suitable for large-scale use of people spray aircraft, so that unmanned aerial vehicles sprayed into a new agricultural equipment industry. Although the agricultural sprayed is still in the beginning stage, but the application of spray unmanned aerial vehicles will become the fastest growing in recent years, an emerging field.
Monitoring of vegetation coverage in agriculture drone
Vegetation coverage is an important parameter to describe the distribution of vegetation on the surface, which is of great significance in the analysis of vegetation cover parameters and evaluation of ecological environment in the area, which is of great value to guide the production of crops. With the promotion and development of precision agriculture in China, relying on remote sensing to detect the change of crop coverage has become an important means of monitoring.
Satellite optical remote sensing and artificial ground acquisition of digital images as a common practice of vegetation coverage statistics in China, there are flaws that are vulnerable to cloud cover and are costly; and artificial ground collection of digital images can not meet the space while being affected by the weather Resolution and time resolution requirements, time-consuming applications in a large area of time-consuming, low efficiency.
The emergence of low-altitude unmanned aerial vehicles is a good way to make up for the lack of satellite remote sensing, improve the efficiency of artificial ground acquisition of digital effects, reduce labor and time waste, improve the accuracy of vegetation coverage monitoring.
China has applied the means of monitoring the vegetation coverage of unmanned aerial vehicles to the coverage of winter wheat. The data can monitor the coverage rate of winter wheat and obtain the threshold of vegetation index dynamically for the study area.
Drone Agriculture sprayer use in agriculture and forestry operations, especially in agricultural plant protection applications, with its efficient, fast, low cost advantage has been the majority of rural collective economic organizations and farmers welcome. However, the current agricultural and forestry plant protection UAV prices generally higher farmers can not afford to bear, seriously hampered the modernization of agricultural plant protection process. Coupled with the crop height and density restrictions, large machinery is difficult to enter the land spraying pesticides, even if the selection of advanced pesticide spraying machinery will cause a certain area of damage to crops, thus affecting the yield. Artificial work, labor intensity is not large, long operating time, poor ventilation and other factors easily lead to the work of drug poisoning and the degree of uneven spraying and so on, fail to achieve the desired results. The solution to these problems seems to be non-agricultural unmanned aerial vehicles.
Efficient and environmentally friendly
Relative to the fixed-wing aircraft, Agriculture drone light weight, small size, mobility is good, do not need professional runway, in the lawn and peace can take off and land, very suitable for the province of complex terrain pesticide spraying pesticide operations. And unmanned aerial vehicles in the operation, the flight speed, and crop distance, spray height and so on can be based on the needs of crops for flexible adjustment. Professional agricultural unmanned aerial vehicles and crops from the minimum distance can be maintained at a fixed height of 1-2m, the scale can also reach 80-100 acres per hour, the efficiency of at least 100 times higher than conventional spraying. Will not cause excessive pesticide spraying phenomenon, can greatly save pesticides and water resources, and to avoid excessive consumption of pesticides and agricultural products harmful to the occurrence of human health; nor pesticide spraying is not enough to eliminate the pests and diseases caused by crop reduction. Environmental pollution can be greatly improved, and due to the use of remote control aircraft, pesticides on the harm of the applicator can also be greatly reduced.
