Description of the Related Art Conventionally, a net-like rug having a width of about 30 cm × 30 cm or 30 cm × 15 cm and a thickness of several millimeters has been used for growing and transplanting lawn in a field. That is, a large number of such rugs are laid side by side next to each other on a field, soil is put on the rug, and a lawn seed is sown. Then, after the lawn buds emerged to grow the lawn, the rug was peeled off together with the lawn, conveyed in a stacked state, and transplanted to another place.

[0003]

However, the work of collecting a large number of rugs having a small area from a field is troublesome. In addition, the lawn root is cut between the rugs during collection. And because the area of the rug was small, the proportion of roots that would be cut was so high that it hurt the lawn. Furthermore, when transplanting the collected lawn to another place, many rugs had to be laid, and a gap was easily formed between the rugs, which was not good in appearance.

The present invention has been made in order to solve the above-mentioned problems, and it is easy to collect the grown lawn, the ratio of cutting roots is small, and it is difficult to form a gap at the time of transplanting, so that the appearance is improved. An object of the present invention is to provide a natural lawn winding device that can be used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. As shown in FIGS. 1 and 2, the rug used in this example has a strip shape having a width W of 1.2 to 1.8 meters and a length L of about 20 meters. The rug 1 itself is made of nylon and is extremely flexible. By using such a flexible thing, the lawn and the rug 1 can be wound and stored or transported due to the flexibility and the vitality of the lawn itself. The mesh-like mesh of the rug 1 may have various sizes, but if it is too large, the grass roots are less likely to be entangled, and the grass may fall off when the rug 1 is wound. Conversely, if the mesh is too small, it lacks flexibility and becomes difficult to wind. Therefore, it is desirable to adopt a mesh range having a size that satisfies the above two conditions.

A downward pin 3 is fixed to the lower surface of the rug 1 as a shift preventing means. The pins 3 are provided, for example, at intervals of 2 meters in the length direction of the rug 1, and the rug 1 is placed on the field.
