The optimum temperature for pumpkin growth is 25-30℃ during the day and 15- 18℃ at night, which can tolerate high temperature of 35-40℃. A certain temperature difference between day and night is beneficial to fruit development and sugar accumulation.

Melon likes the environment with high temperature and dryness, strong light and large temperature difference between day and night, which requires high cultivation techniques. At present, it is mainly planted in greenhouses. Usually a large number of melons are listed in June and July, and gradually fade out of the market after autumn, which is greatly influenced by seasonal factors. The growth period of netted melon is relatively short, and it can be planted twice a year, both in spring and autumn.
