The temperature of tomato transportation is generally controlled at 10-13℃, and the humidity is kept at 85%~90%. If the transportation time is long, air-conditioned refrigerated vehicles can be considered to be used. By adjusting the gas composition in the vehicle, the oxygen content is reduced, the carbon dioxide content is increased, the fruit respiration is inhibited, and the shelf life is prolonged.

[0003] A kind of shock-absorbing fresh-keeping box suitable for tomato cold chain transportation is disclosed in Chinese patent No. 202222326485.6, comprising a box body and a shock-absorbing part arranged in the box body.
