One or both supplementation methods can be selected according to actual production needs. 6.3.1 Leaf surface supplementation: Prepare a selenium solution with a concentration of 70mg/kg to 120mg/kg. Supplement selenium once each during the heart-leafing stage, tuber formation stage, and bulb enlargement stage, with 450kg to 650kg of selenium solution evenly sprayed per hectare per time. Ensure that both sides of the leaves are sprayed with selenium solution, with no dripping. Apply selenium on cloudy days or after 4 PM on sunny days. Use a fine mist sprayer to
