When does watermelon ripen?
In summer, the south ripens in early June, and hundreds of watermelons ripen at different times. Watermelon is on the market in May of the lunar calendar. Watermelon has obvious seasonal characteristics in large-scale production because of its own habits, product attributes and people's consumption habits. The first is flowering and fruit setting, especially the growth and development of fruits need relatively high temperature conditions, and the growth and development will stagnate when the temperature is lower than 15.
Watermelon can be divided into fresh watermelon and seed watermelon. The selected watermelon varieties are mostly fresh watermelons, which are the main types of watermelon cultivation and the varieties with the highest utilization rate of heterosis. Seed melon has strong adaptability, high seed setting rate of lateral vines and extensive management, and its seed selection is the same as that of fresh watermelon.
Matters needing attention in purchasing watermelon
1. Look at those melons and vines. The greener they are, the fresher they are Yellow or shriveled for a long time. Then it is thinner than thick and sweeter than straight. By the way, look at the appearance after watching the melon vines. We mainly eat local mineral melons. The rounder the better. We should buy as few melons as possible.
2, take a shot, the most commonly used method, you can distinguish the thickness of the melon skin by shooting, the thinner the better. After the thin-skinned watermelon is photographed, the fingers can feel the buzzing rebound sound, which sounds like a drum, or like the sound of patting people's chest, and it can be confirmed that it is a mature sand melon. If the sound is boring and there is no rebound, don't buy it.
3. Look at the navel of the melon, which is the circle at the bottom of the watermelon. Many people can see whether it is a "mother" watermelon through this point. This circle is big and small, and it is a good watermelon, regardless of the size. On the contrary, buy less if it is not round.
