There are many ways to accelerate the germination of watermelon seeds. Here are some common methods:
Method of accelerating germination in incubator: adjust the incubator to 28 ~ 30℃ when accelerating germination (adjust it to 30 ~ 32℃ when accelerating germination of seedless watermelon). Drain the soaked seeds, spread them on the wringed wet gauze with a thickness of no more than 2 ~ 3 layers, cover them with 1 ~ 2 layers of wet gauze, and then wrap them with plastic cloth.
You can also mix the seeds with the same amount of river sand and put them in an aluminum box. The humidity of river sand should be rubbed by hand but not squeezed out with water, and covered with a wet towel. The treated seeds are put into a constant temperature box to accelerate germination, and can basically germinate in 24 ~ 36 hours.
Body temperature germination method: wrap the seeds not exceeding 100g with wet gauze, put them in a double-layer plastic bag, tie the bag mouth tightly, put them in the innermost clothes pocket close to the body, and germinate by body temperature. Replace the inside and outside of the seed bag every once in a while to make it evenly heated. Generally, germination begins in 24 ~ 36 hours, and most seeds can be sown when they turn white.
Electro-optical germination method: use old paper boxes, spread thermal insulation materials such as cotton coats on the bottom and around the paper boxes, wrap seeds with double-layer cotton cloth that has been twisted with water, wrap them with agricultural film to keep them moist and put them on the thermal insulation at the bottom of the paper boxes, and insert a thermometer into the seed bag and extend out of the paper boxes to check the temperature.
Hang a 40-watt light bulb on the seed package10 ""15 cm, and cover the top of the carton with a cotton coat. Turn on the light for heating. When the temperature rises to 28 ~ 30℃, pay attention to the change of thermometer. If it exceeds 32℃, you can increase the height of the bulb, or peel off the cotton-padded clothes covered on it. If the temperature does not reach 28℃, the height of the bulb can be reduced.
The method of accelerating germination with electric blanket: put the electric blanket flat on the quilt or mattress, spread a layer of plastic agricultural film on the electric blanket, put wet water on the plastic agricultural film and screw out a double-layer cotton cloth, put the seeds on the cotton cloth, then wrap the seeds with a double-layer wet cloth, insert the thermometer into the seeds and extend out of the quilt, then cover them with the agricultural film for moisture retention, then wrap them with the electric blanket, and finally cover the electric blanket with the quilt to keep warm, and turn on the power to accelerate germination.
Extended data:
Large-fruit watermelon variety Yi is a medium-ripe watermelon variety, which is famous for its large melon size and high sweetness. Its appearance is particularly beautiful. The whole growth period is about 100 days, and the plants grow vigorously, with good and neat fruit setting, rapid melon expansion, thin skin and toughness.
Watermelon variety No.1 with large fruit type has strong crack resistance, storage and transportation resistance, oval fruit, good peel color, clear and uniform stripes, no random lines, red flesh, crisp and tender meat, excellent quality, central sugar content 13 degree, average single fruit weight 10-20 kg, and strong disease resistance. It is an excellent watermelon cultivated in greenhouse and open field.
Shi Lei 5 1 1 is a new variety improved on the basis of No.5, with darker color, better taste and round fruit, which can be planted all over the country.
Watermelon seed Shi Lei No.5 is the best watermelon seed in China at present, with large fruit shape, thin skin, small seed, red flesh, single melon 10- 15 kg, strong disease resistance and strong fruit setting. The fruit is highly round, does not crack, has fast transportation speed and high sugar content.
Watermelon seed is a giant fruit, weighing 9- 18kg, with vigorous growth, strong disease resistance, continuous cropping resistance, easy fruit setting, oval fruit, uniform fruit and no deformity. The flower skin is large, the color is green, and the skin is thin and tough, which is suitable for long-distance transportation.
