When planting seedless watermelon, the seeds should be soaked in warm water for 6-8 hours, and then use sterilized scissors to cut the umbilicus, and plant it in the soil after germination at a constant temperature, and also control the temperature difference between day and night at 5-6 degrees.
The full name of seedless watermelon is triploid seedless watermelon, also known as unicorn melon, which is a hybrid of diploid watermelon and tetraploid watermelon, and its fruit does not contain seeds, so seedless watermelon itself has no reproductive ability.
Soak the seedless watermelon seeds with warm water at 50 degrees Celsius, stir constantly, soak them in water for 6-8 hours after cooling, wrap them in a wet towel after taking them out, and cut the umbilicus of the seeds with sterilized scissors in order to improve their germination rate, put them in the incubator, and germinate them after one day.
Before sowing, the soil is watered thoroughly, and then the seedless watermelon seeds are planted into the soil, and the germinated end is facing up, and its top soil ability is weak, so the thickness of the covering soil can not exceed 1 cm, and finally a layer of plastic film is spread on the bed surface to keep warm and moisturize.
After the seedless watermelon is planted, the temperature difference between day and night should be controlled between 5-6 degrees, which will help it accumulate sugar, and the plant is not resistant to strong direct light, and the shade net should be used at high temperature at noon to reduce water evaporation, and then gradually remove the cover after 3 days, appropriately increase the light intensity, and there will be no need for shade after a week.

Seedless watermelons are seedless.
In 1947, Japan cultivated the world's first seedless watermelon, which was put into production in 1949. Seedless watermelon is not only firm but also sweet and juicy, which is popular with many people.
To cultivate this seedless watermelon, the main thing is to use the mutagenesis method. Seeded watermelons are diploid plants, whereas seedless watermelons are triploid plants. Before cultivating triploid watermelon, it is necessary to choose excellent diploid watermelon, and then artificially induce it into tetraploid.
The successfully induced tetraploid watermelon is used as the mother, and then the double-Kai stove watermelon is used as the paternal parent, and then the two are cross-produced, and in this operation, we can obtain the triploid seed of Sun Xunzi, that is, the seeds of seedless watermelon.
