Farmers in southwest China's Xizang Autonomous Region have begun spring plowing this week, guided by a 700-year-old astronomical tradition at the Dapu Astronomical Observation Station. As sunlight streamed through the station's roof aperture on March 11, 2026, aligning perfectly with its ancient stone marker, local agricultural communities received their annual signal to prepare fields for planting.
The unique solar observation method, maintained continuously since the 13th century, demonstrates how traditional knowledge continues to inform modern agricultural practices. While satellite technology now supplements these observations, many farmers still regard the solar alignment ritual as crucial for determining optimal sowing times in the high-altitude region.
This year's plowing season coincides with new government initiatives to preserve cultural heritage sites while improving agricultural productivity. The Xizang Autonomous Region has allocated special funds to maintain the Dapu station and document its historical significance, ensuring this living link to China's astronomical heritage remains operational for future generations.
