    Cultivation Guidelines
    1. Soil Preparation – Select loose, fertile, well-drained soil; apply fully decomposed organic fertilizer. Avoid chemical fertilizers to prevent seed or seedling rot.
    2. Sowing – Follow local sowing schedules. Seeding rate: 200-300 g per mu for nursery raising, 1000-1500 g for direct sowing.
    3. Transplanting – Cover with mulch before winter. Standard spacing: 19 × 17 cm. Transplant seedlings when 6-8 g weight, 0.4-0.6 cm pseudostem thickness, 3-5 true leaves, and dark green color.
    4. Bolting Management – Remove flower stalks if bolting occurs; this does not reduce yield.
    5. Watering – Maintain soil moisture during bulb expansion; stop irrigation 7 days before harvest.
    6. Harvesting – Avoid trampling plants during bulbing to prevent yield loss.
