[0002] Seedling cultivation means to cultivate seedlings. Originally, it refers to cultivating seedlings in nurseries, hotbeds or greenhouses in preparation for transplanting them into the soil for planting. It can also refer to the stage when various organisms are artificially protected when they are small until they can survive independently. As the saying goes, "a strong seedling is halfway to the harvest." Seedling cultivation is a labor-intensive, time-consuming and technical job, and seedlings are moved short distances by carts.

[0003] During the use of the existing seedling cart, the ground is relatively bumpy, which may cause the car body to shake while driving, causing the seedling tray to slide on the pallet and fall from the pallet to the ground, resulting in seedling losses. For this reason, we propose a seedling cart. Utility Model Content
