At present, there are more and more growers of asparagus in the market, and the scale of planting asparagus is also increasing. After harvesting a large number of asparagus, it is impossible to sell all of them on the same day, and they need to be stored to ensure the quality of asparagus However, most of the storage methods currently on the market are relatively traditional, and the storage time should not be too long. After a long time, the quality of asparagus will decline or even rot. This will bring a lot of troubles to large-scale growers and bring great economic loss
