Watermelon should be turned over in time

Since watermelon always has one side in contact with the ground when it is sitting on the melon, the side that touches the ground is called the pubic surface because it cannot be directly irradiated by sunlight. The growth of the watermelon epidermis is relatively slow, and the internal development of the fruit is not uniform. The melon is hard, the melon is thick, and the sugar content is low. If you turn the melon in time after setting the melon, it will improve the commerciality of the watermelon.

Specific practice: Turn the melon at noon to evening in the sunny day, hold the melon handle in one hand while turning the melon, and secure the melon body with one hand, with both hands, gently twist. Every time you turn in the same direction, you must never twist. Every 2 to 3 days, the angle of rotation should not exceed 30 degrees. Generally, each side of the melon turns 2 to 3 times to turn the shade to the sun. In case of rainy days, increase the number of turning melons. Linyi Fertilizer Network Copyright
