1. Watermelon seeds come from special watermelons, called seed watermelons, also called seed melons, which are a variety of watermelons. Because they are relatively strong, they need to be punched and kicked to open them, so they are also called "breaking melons". We can get the watermelon seeds we eat by "breaking melons".

2. Take the green-skinned black-seeded melon as an example. Generally, you can't pick it until the skin turns yellow, and then dig out the seeds about 15 days after ripening. You can use manual or mechanized automatic digging out the seeds. The melon seeds should be directly dried. If washed with water, the color of the melon seeds will become lighter and the appearance quality will decline.
