Key Technical Points for Seedbed Management During the Watermelon Seedling Emergence Stage

(Agricultural Wealth Network) First, check promptly. If the seedbed soil is too dry or there are signs of seedling scorching, the problem should be solved promptly. Second, uncover the film and water promptly. When 80% of the melon sprouts have emerged from the soil, the plastic film covering the seedbed can be removed. If the seedbed soil is too dry when the melon sprouts emerge, or if the soil is too wet and forms clods, the sprout roots may be exposed and die from drying. Water should be applied promptly to firm the surface soil, or the soil clods should be crumbled and the seedlings covered again. Third, remove the caps. Some varieties emerge with the seed shell still attached, so the caps should be removed promptly when the film has just been uncovered, after watering, or before ventilation each morning while the seedbed soil is moist. Fourth, ventilate appropriately. After most of the melon seedlings have emerged, the seedbed should be ventilated appropriately to lower the temperature and humidity, control excessive leggy growth, and reduce disease.
