Seedling raising of watermelon cultivated in summer and autumn

It is appropriate to use small high border nutrition bowl to raise seedlings and cover nylon screen to effectively prevent thundershowers, insect pests and proper sunshade. Nursery beds should be built in high and dry places, generally 8 to 10 meters long and 1.2 meters wide. When building a seedling bed, first build a small high bed with a height of 15 centimeters and a width of about 1.5 meters, and discharge nutrition bowls on it. After the bowl is poured and sown with water, the thickness of the covered soil is about 1.5 cm, covered with plastic film, covered with soil or grass shade. The sowing date should be 5 to 7 days earlier than the live broadcast. After emergence, the mulch should be removed in time, properly watered, and often watered to keep moist.
