When planting watermelons, select seeds with full and undamaged seeds, and then soak them in carbendazim for 10- 15 minutes to eliminate the germs on the surface of the seeds and reduce the infection rate of watermelons. Then put the watermelon seeds in an environment of about 33 degrees to accelerate germination and promote their vigorous growth.

2. Planting method

Watermelon is suitable for growing in loose and breathable sandy loam. When planting watermelon, it is necessary to spread its seeds evenly on the soil surface and then cover them with plastic film to keep the temperature in the soil constant. After watermelon emerges, it is necessary to cut the plastic film near its seedlings with a knife to make the plants grow healthily.

3. Maintenance management

When maintaining watermelon, it is necessary to apply human and animal manure once after the plants germinate, which is beneficial to improve the growth speed of watermelon. During the growth of watermelon, it is necessary to spray potassium dihydrogen phosphate regularly to promote the differentiation of flower buds. After the watermelon blooms, the extra flower buds should be cut off to improve the fruit quality of the plant.
