Potato is generally planted in the soil, but the land needs to be dug during planting and harvesting, which is time-consuming and laborious. When fertilizing, it is not easy for the fertilizer to act directly on the roots of the potato, and it occupies a lot of land.

[0003] Therefore, there have emerged a potato virus-free seedling hydroponic planting device disclosed in the utility model patent with application number 202220717215.5 and a potato hydroponic bed disclosed in the invention patent with application number 201610539570.7, which use hydroponics to plant potatoes, improve planting efficiency, and reduce land occupation.

Potato seedlings need to be used for soil culture or hydroponics, resulting in poor practicality. Therefore, there is an urgent need for a cultivation method and equipment for improving the uniformity of processed potato tubers. Summary of the invention

After the potato seeds germinate and grow into seedlings, the root system passes through the fixing mechanism and extends into the supporting mechanism, and the pressurizing mechanism is closed, so that the feeding mechanism continues to provide water and nutrients for the potato seedlings, so that the potato seedlings continue to grow, and the roots of the potato seedlings are agglomerated, and the size of the potato tubers is detected by a detection mechanism, and then the feeding mechanism is used to supplement nutrients for the smaller potato tubers, so that the size difference between the potato tubers is reduced, and the potatoes are harvested after they are mature, thereby improving the practicability of the equipment and a cultivation method and equipment for improving the uniformity of processed potato tubers.
