Vernalization generally refers to the phenomenon that plants must undergo a sustained low temperature for a period of time to go from the vegetative stage to the reproductive stage. In the test cultivation process of wheat, the wheat is also required to be subjected to vernalization treatment, so that the wheat is subjected to vernalization and then grows. Winter wheat and semi winter wheat which are not vernalized can not be subject to the phenomena of heading or delayed heading after sowing, heading irregularity and the like, and the yield is low.

In the greenhouse planting and experimental cultivation process of wheat, an artificial vernalization chamber or a low-temperature box is generally adopted to provide a low-temperature environment for one end time for wheat to finish vernalization. However, because the space in the vernalization room or the low-temperature box is limited, people usually adopt a concentrated close planting vernalization method, and the utilization rate of the vernalization room or the low-temperature box is ensured by transplanting after vernalization. However, the traditional transplanting work needs to scoop gaps around wheat seedlings, then digs out the wheat seedlings and roots integrally by utilizing a scoop, and needs to match with both hands so as to avoid that the root soil falls off in a large amount, and the process is complex, time-consuming and labor-consuming.
