1. Seed selection treatment: select lettuce varieties with strong disease resistance and strong growth, select lettuce seeds with full grains, and soak the seeds in advance to accelerate germination.

2. Sowing and seedling raising: select loose and fertile organic nutrient soil, sow it, and keep it moist after sowing.

3. Planting: When the seeds germinate and grow two or three leaves, plant them at a reasonable density.

4. Field management: After lettuce planting, pay attention to daily watering and fertilization, weed regularly, and pay attention to pest control.
