　　As temperatures continue to rise, Northeast China is welcoming the busy spring sowing season.

　　At a vast farm in the Changchun National Agricultural High-Tech Industry Demonstration Zone in Changchun, Jilin province, a group of unmanned agricultural machines are plowing, sowing, fertilizing and covering crops.

　　The machines, equipped with the Beidou Navigation Satellite System, can accurately execute planned routes and work autonomously in the field.

　　There is also some testing equipment at work to provide data such as soil moisture, fertility, illumination and rainfall, to a big date platform.
