Detailed Explanation of Key Techniques for Raising Tomato Seedlings in the Autumn-Winter Season

1. Select good varieties: sow early at the right time. Choose good varieties that set fruit easily early, tolerate low temperatures and weak light, are suitable for dense planting, early-maturing, high-yielding, high-quality and strongly disease-resistant. Each bottle of New High-Lipid Membrane stock solution is generally diluted with 5-10 kg of liquid; after soaking the seeds, remove them and let them dry before sowing. It can preserve heat, retain moisture and promote imbibition, improve the seed germination rate and make the seedlings sturdy. It repels underground pests and isolates viral infection. It can also be mixed with seed coating agents.

2. Seedbed preparation: during the seedling-raising period for autumn-winter season tomatoes in a solar greenhouse, the seedbed should have conditions for preventing rain and waterlogging, ventilation and cooling, and must be covered with film; only seedlings cultivated under such conditions can adapt to greenhouse conditions. Apply 20 kg of decomposed farmyard manure per sq m, dig 10 cm deep, and rake the bed surface level.

3. Sowing: irrigate the seedling bed thoroughly; after the water seeps down, sow in holes at a plant and row spacing of 10-12 cm, sow 2-3 seeds per hole, and cover with 1 cm of nutrient soil. Keep the bed surface moist before emergence.

4. Seedling-stage management: after emergence, keep one sturdy seedling per hole and cut off all the rest. Avoid drought during the seedling stage and maintain air-dried, wind-dried conditions. Spray New High-Lipid Membrane + insecticide once every 7 days to prevent the spread of viral diseases. Autumn-winter season tomato seedlings are raised in about 30 days into age-appropriate sturdy seedlings with 4-5 leaves and a plant height of 20-25 cm.
