Description

technical field [0001] The invention relates to the technical field of fruit and vegetable preservation, in particular to a fruit and vegetable preservation carton. Background technique [0002] Fruit and vegetable rot is the root cause of the short shelf life of fruits and vegetables, and the humidity, temperature, cleanliness and oxygen concentration of the fruit and vegetable storage environment are the main factors causing fruit and vegetable rot. The rot speed of fruits and vegetables is proportional to the values ​​of the above four factors. , that is, the higher the temperature, the greater the humidity, the worse the cleanliness, the greater the oxygen concentration, and the faster the rot of fruits and vegetables. [0003] At present, the fresh-keeping methods of fruits and vegetables mainly include methods such as low-temperature storage, controlled-atmosphere storage, and chemical agents. Both low-temperature storage and controlled-atmosphere storage require cert...
