In order to increase the weight of a single melon and make the melon shape straight, the melon sitting on the second female flower should be selected. If you put the melon too early, it will be small and the shape of the melon will not be straight. If it is too late, it is not conducive to the previous market. Generally, the melon embryo will grow obviously 3 ~ 5 days after pollination, so the melon should be left on the main vine first. Can't stay on the main vine, you can leave the melon on the side vine. In the case of bracket cultivation, when the melon grows to the size of a bowl, about 0.5 kg, it should be hung up in time to prevent the young melon from falling after growing. In the case of climbing cultivation on the ground, melons should be selected, padded and ploughed like arch shed cultivation.
