With the development and popularization of tobacco floating seedling technology, and the professional service intervention of tobacco farmers' professional cooperatives in the process of tobacco seedling cultivation, the model of base-based seedling cultivation, professional services, and commercial seedling supply has achieved full coverage; the early stage of tobacco floating seedling preparation focuses on two aspects: one is the leveling of the bottom of the seedling pond; the other is the laying of the pond membrane; in the laying of the pond membrane, since the current seedling greenhouses are all medium greenhouses or large greenhouses, the seedling ponds in the greenhouses are mostly arranged in a grid format, and the pond membrane specifications used are generally 3.5m wide and 4.2m wide. Both types are relatively wide, and the weight of a single pond membrane is heavy, generally more than 15kg, and it is not easy to move at will. In addition, the seedling pond is generally surrounded by hollow cement bricks with sharp edges and corners, which can easily scratch the pond membrane, causing the seedling pond to leak, and in the process of laying the pond membrane, auxiliary devices are needed.

[0003] There are currently two traditional methods for laying pond membranes in seedling ponds. One is to do it manually, in which the pond membrane is placed on the ground and pulled to roll the membrane tube on the ground. This method of laying can easily damage the pond membrane, resulting in waste of the pond membrane. The other is to use a wooden support frame, insert a steel pipe into the membrane tube and place it in a U-shaped groove of the support frame, and lay the pond membrane through the cooperation between the support frame and the steel pipe. This type of pond membrane support frame is usually an integrated structure, and the height and spacing cannot be adjusted according to the needs of pond membrane laying during use.
