There is an "artificial oasis" in the tropical desert, and China's rice grows!

The Qingdao Sea Rice R&D Center team, led by Yuan Longping, an academician of the Chinese Academy of Engineering, recently conducted field tests on rice that was experimentally planted in the tropical desert of Dubai . The maximum per mu production exceeded 500 kilograms. This is the first time that the world has successfully experimented with rice cultivation in tropical deserts, adding "China's contribution" to improving the self-sufficiency of grain in desert areas, safeguarding global food security, and improving the ecological environment in desert regions.

Agricultural drones refer to drones for plant protection, which can be used for pesticide spraying by remote control or flight control. Agricultural drones features cheap price, small volume, light weight, and convenient transportation, which can realize vertical take-off and landing (while rotor-winged drones and fixed-wing drones need a runway) and be flexibly controlled. In addition, they show perfect adaptability for different regions, plots, and crops. Therefore, in China's northern or southern areas, hills or plains, big or small blocks, agricultural drones have broad application. Agricultural drones can be divided into the stiff-wing, single-rotor, and multi-rotor drones according to the flyway. Electric multi-rotor drone is well acknowledged by customers and occupies the highest market share nowadays because of its cheap price, as well as easy maintenance and operation. The advantages of agriculture drones 1. Safety and efficiency The working efficiency of the agricultural droes is at least 30 times higher than that of conventional spraying. They can be operated through remote control, thus the risk of pesticide poisoning can be prefectly avoided while the security of the spraying can be effectively improved. 2. Perfect prevention efficiency The higher the coverage density of the spraying liquid on a unit area, the more uniform the control effect is. The drone is a spiral machine slurry and has a low working height. When the liquid droplets are ejected from the sprayer, they are accelerated by the downward airflow of the rotor to form an aerosol flow, which directly increases the penetrating power of the liquid droplets on the crops and reduces the loss of pesticides. The deposition of liquid chemicals and liquid coverage are superior to those of conventional spraying. It has a better control effect and reduces the pollution of pesticides on the soil. 3. Saving pesticide The drone spraying technology can save up to 50% pesticide and 90% water, which will red
