How should spring corn seeds be treated before drought-resistant sowing?
Before sowing, select and sun-dry the seeds. Choose uniform, consistent seeds and sun them for three days on a sunny day to improve germination vigor, disease resistance, and seedling uniformity. Conduct a germination test before sowing. The purity of the selected seeds should be no less than 96%, the cleanliness no less than 98%, and the germination rate no less than. Seed coating.

Before sowing, select and sun-dry the seeds. Choose uniform, consistent seeds and sun them for three days on a sunny day to improve germination vigor, disease resistance, and seedling uniformity. Conduct a germination test before sowing. The purity of the selected seeds should be no less than 96%, the cleanliness no less than 98%, and the germination rate no less than.
Seed coating. Use a drought-resistant compound seed coating agent to coat corn seeds, to prevent and control pest and disease damage at the seedling stage, and to enhance root vitality and the plant's own stress resistance. Corn seeds that have been pre-germinated must not be coated, to prevent chemical injury.
Pre-germination. 2-3 days before sowing corn, soak the seeds in 40°C water for 8-12 hours, then remove them and place them at room temperature of 20°C-25°C for pre-germination. After the seeds show white sprouts, place them in a cool, dry, shaded place to air-dry for 6 hours to harden the sprouts.
