First, the seed disinfection. Before sowing, the seeds were soaked in water for 2-3 hours and then dressed with a new high fat film. Can keep warm, moisturize, absorb, increase seed germination rate, make seedlings robust. Repel underground pests and isolate virus infections. Can also be mixed with seed coating agents.
Second, water and fertilizer management. Bottom water after adequate control of water pouring, especially after sowing and just emerged, should pay attention to appropriate water control and improve the management of temperature, avoid pouring large flooding or flooding. The timely spraying of photosynthetic nutrient film fertilizer at the seedling stage can help the growing vegetables absorb light energy, improve fertilizer efficiency, enhance vitality, moisten rain, and thrive.
Third, chemical control. Timely removal of diseased seedlings and adjacent diseased soils, combined with chemical control, can be achieved with roots and fungicides, followed by evenly spreading fine soil or plant ash to reduce the humidity of seedbeds, and pay attention to increase soil temperature after application.
