Description

Technical Field

[0001] The invention relates to the technical field of storage boxes, in particular to a sweet potato seed storage box. Background Art

[0002] Sweet potato seed storage can generally be divided into equipment storage and cellar storage. Cellar storage cannot flexibly control storage conditions. The appropriate temperature for sweet potato seed storage is controlled at 10℃ to 14℃, and the humidity is maintained between 85% and 95%. This is the best way to ensure the quality of seed potato preservation. Cellar storage cannot well control and adjust storage conditions. On the other hand, the workload is large and it is not convenient to check the storage conditions regularly. Therefore, more and more storage boxes are used to store sweet potato seed potatoes. However, there are still some problems in the use of existing storage boxes, as follows: The existing storage boxes cannot separate and store the sweet potatoes well during storage, and most of them are stacked for storage. This is not only not conducive to the gas flow inside the storage box, but also causes different respiration degrees of the sweet potatoes in different positions. At the same time, since it is impossible to completely guarantee that each sweet potato can be stored normally, it is necessary to open the storage box regularly for inspection. However, the existing storage boxes cannot be conveniently inspected for storage conditions due to the stacking method, and the storage box needs to be completely opened, which will cause all the sweet potatoes in the storage box to be exposed to the current air environment for a long time, which will cause abnormal respiration of the sweet potatoes, thereby greatly increasing the probability of sweet potato corruption and disease. Therefore, the existing storage boxes cannot guarantee the storage effect of the sweet potatoes well. For this reason, we propose a sweet potato seed potato storage box. Summary of the invention
