Rice planting usually includes sowing, seedling cultivation, transplanting and other processes. In Jiangsu and other places, the rice harvest progress has exceeded 90%, and a bumper harvest for the whole year is in sight. After the rice is harvested, the rice needs to go through processes such as shelling and milling before it can become the rice we eat daily.
