Propagation methods for kohlrabi
1. Seed treatment: To prevent the seeds from carrying pathogens, soak the seeds in carbendazim for 24 hours before sowing to disinfect them.
2. Seedbed soil disinfection: 20 days before sowing, pour 50 milliliters of formalin mixed with 3 kilograms of water onto the nutrient soil, then cover with plastic film and pile it to ferment for about 5 days. You can also mix 50% carbendazim wettable powder into the nutrient soil to disinfect and sterilize the soil.
3. Cultivating strong seedlings: Starting in mid-December, use the small arched shed method to raise seedlings in seedling trays. Prevent raising seedlings too early, because a long seedling age easily causes bolting.
4. Seedbed management: Generally, seedlings emerge 5 days after sowing. Check the seedbed every day. When the temperature is high, pay attention to ventilation to prevent the seedlings from being scorched; when the temperature is low, cover the film well to prevent the seedlings from freezing. Replenish water once a week; when the seedlings grow to 2 leaves and 1 heart, thin the seedlings to prevent excessive growth and ensure the seedlings are uniform in size; when the seedling stem diameter reaches more than 0.5 cm, try to keep the temperature above 15°C to avoid passing through the vernalization stage; 7 days before transplanting, ventilate to harden the seedlings. When the seedlings grow to 5-6 true leaves, transplanting can be carried out.
