Detailed Explanation of Key Techniques for Raising Watermelon Seedlings in Summer-Autumn Cultivation

It is advisable to use small raised-bed nursery pots for raising seedlings, covering them with nylon mesh to effectively prevent thunderstorms and pest damage and to provide appropriate shade. The seedling bed should be built in a high, dry location, generally 8 to 10 m long and 1.2 m wide. When building the seedbed, first make a small raised bed 15 cm high and about 1.5 m wide, and arrange the nursery pots on it. After arranging the pots, watering thoroughly and sowing, cover with soil to a thickness of about 1.5 cm, cover with plastic film, and then cover with soil or straw matting for shade. The sowing date should preferably be 5 to 7 days earlier than direct sowing. After seedlings emerge, promptly remove the covering, water appropriately, and water frequently to keep moist.
