In exploring the development of modern agriculture, drones are also playing an increasingly critical role in ensuring food security. However, how to continuously improve agricultural production efficiency and increase China's food self-sufficiency rate? Digital agriculture may become the key to problem solving.
In the previous tweet, it was mentioned that the farmland prescription map can be generated through the plant protection data collected by the multispectral camera, which can judge the crop growth and provide a more accurate data reference for farmland management.
But how to use farmland prescription maps efficiently?
With a plant protection drone with precise spreading (spraying) function, variable spreading can be realized. Simply put, it means spreading more fertilizer in weaker growing areas, and less or no spreading in better growing areas, thereby further increasing farmland yield, reducing costs, and ultimately increasing planting profits.
In 2020, AGR Agriculture will set up 200 acres of “precision fertilization” experimental fields in Jiangsu Sino-German Crop Production and Agricultural Technology Demonstration Park. Use the multi-spectral AGR A16 drone to monitor growth in the "catching yellow pond" and spike fertilizer stages, generate prescription maps, and then guide precise variable fertilization.
The results after several rounds of operations showed that variable fertilization effectively adjusted the difference in field growth and improved the uniformity of growth. In terms of field inspection and fertilizer application efficiency, drones have also reached about 5 times that of manual operations.
