How to germinate watermelon seeds
1. Sun drying
Before the seeds are treated, they need to be dried in the sun, and the drying time should not be too long. Generally, they need to be dried for a few hours to dry out some of the moisture inside the seeds. During the drying, the seeds should be re-heated to be evenly heated to ensure that the water loss is even. Seeds after sun drying are easy to germinate, which is good for seed soaking.
2. Stirring seed soaking
For seed soaking, the seeds must be soaked in warm water. Generally, the water temperature is around 50°C. If the skin is thin, the water temperature can be adjusted to ensure that the seeds cannot be harmed. The general water temperature will also gradually drop. Stirring seed soaking, after a period of time when the water temperature drops, you can soak seeds directly without stirring.
3. Insulation and germination
The seeds can germinate after swelled by absorbing water, about one to two days after soaking. Germination is mainly heat preservation and germination. There are many methods. For example, the common method is to wrap the gauze in the insulation box to germinate after draining the seeds. Set it between 22°C and 25°C, wash it once a day, and germinate or germinate after a few days. Generally, the seeds are wrapped with a damp cloth, and then wrapped with a waterproof cloth bag, which is sprouted on the body and germinated by body temperature, which can be viewed and removed after the germination. Most methods of germination are heat preservation and germination.
Four, rapid germination
If you are about to pass the sowing period, but want to sow, you can also urgently germinate, and quickly plant after germinating. However, some special treatments should be performed on the seeds. After soaking, use small scissors to artificially break the seed coat at the top of the seeds. Just cut a small mouth and do not hurt the inside of the seeds. Then put it in the incubator to germinate, so that the white is faster.
5. Sowing
Seeds that germinate and show off white should be sown, pay attention to that, the sprouts should be facing down, or covered with thin sand, otherwise the new shoots will easily lose water and die. It is best to sow in containers, not in open fields. Container sowing is easier to manage and saves seeds. After sowing, the fine sand culture soil is directly configured, which is easy to grow and moisturize, which is beneficial to emergence.
