Crop Rotation Technology A two-minute silent educational picture film with Chinese and English captions. Real photographs are credited on screen; AI reconstructions are marked and are not microscopy or measurement evidence. Gentle digital camera movement does not represent recorded machine or biological motion. Field settings require local adaptation. Photographs come from different fields and dates, not a controlled comparison. Some images are reused across this series. Companion article: CA-009.
