The main reason for the late emergence was due to the low temperature and rainy weather after the nursery. The water in the bed was infiltrated, and the water surface of the bed soil was lack of water and the seedlings were affected. Should be selected at noon on a sunny day with a sprayer to spray water to add moisture, maintain humidity and promote seedlings.
Burning seedlings sprouting occurred in the middle of growing seedlings with varying temperature, which is a kind of high-temperature physiological disaster caused by poor management during seedling period. The ventilation management should be well done on sunny days, especially when the temperature at noon on sunny days exceeds 20°C and the film is fully uncovered.
Flash seedlings are a kind of physiological disease caused by improper ventilation and management that cause mutations in the growth environment of seedlings. After the seedlings have been removed from the membrane, atrophy occurs, and then the leaf margins roll up and the leaves turn white and dry. Attention should be paid to timely ventilation. The air outlet should be opened on the leeward surface and the air outlet should be replaced.
Zombies and seedlings are physiological obstacles caused by poor soil management and irrational seedbed structure in seedbeds. They are characterized by small yellow leaves, slow growth, and fine and hard stalks. The light should be increased, and the water in the seedling stage should be filled timely, and the soil moisture in the bed soil should be maintained 70%~80%, and the foliar fertilizer should be sprayed to enhance the seedling growth.
Seedling disease prevention Pepper seedling disease is mainly damping-off disease, blight. Low temperature and high humidity can easily cause damping-off, and high-temperature and high-humidity are prone to blight. Use 70% thiophanate-methyl 800 times or 50% mancozeb 500 times liquid spray for prevention.
