In the figure, a protective sheet 10 for fruits and vegetables is made of a brass plate 5 thin metal plate or the like 2, and includes a corrugated plate 16 in which a convex ridge surface 12 and a concave surface 14 are alternately continuous, and a corrugated plate 16 that has a continuous convex ridge surface 12 and a grooved surface 14, and a convex ridge surface 12. The fruit/vegetable locking portion 18 is comprised of a large number of concave portions or convex portions, and a plurality of holes 20 are formed in the concave direction 14.

Then, in order to plant melons, watermelons, etc. in the field, a protective sheet 10 for fruit vegetables is laid on the top surface of the vinyl film covering the ridges, and the vines of the seedlings of fruit vegetables planted in the ridges are covered with -F of the protective sheet 10. The fruits and vegetables that have ripened while growing along the surface are received by the convex ridge surface 12, and the gaps with the four-striped surface 14 maintain air permeability and light emitting properties, without causing corrosion or loss of color in the fruits and vegetables. , it becomes possible to produce high-quality fruits and vegetables.

As shown in FIGS. 3 and 4, the fruit and vegetable locking portions 18 provided in large numbers on the convex ridge surface 12 are recessed downward on the upper surface of the convex ridge surface 2, and the inner bottom surface 22 is located on both sides of the convex ridge surface 12. It includes a concave portion 18a that is recessed so as to communicate with the surface, and a convex portion 18b that is stepped upwardly on the upper surface of the convex ridge surface 2 as shown in FIG.

The vegetable locking portion 1 is composed of the concave portion t8a and the convex portion 18b.
8, it is possible to prevent the growing fruits and vegetables from slipping when the protective sheet [0] is laid down at an angle.

In addition, since the inner bottom surface 22 of the recess 18a communicates with both sides of the convex ridge surface 12, the water sprinkled on the vines of growing fruits and vegetables flows out from within the recess 18a and does not accumulate, causing rot. It never becomes. Moreover, even in the case of the convex portion 18b, water does not accumulate.

Furthermore, fruits and vegetables have a convex ridge surface 12 provided with a large number of concave portions 18a.
or the many convex portions 18b, and the concave surface 1
Together with the gaps 4, ventilation and light emitting properties are improved, and it is possible to prevent rotting and loss of color in growing fruits and vegetables.

The holes 20 formed in the grooved surface 14 of the corrugated plate 16 are used for drainage of water flowing through the grooved surface 4, and for attaching the protective sheet 10 by driving wedges into the ridges through the holes 20. Alternatively, in the joint portion of the protective sheet 10, the ends of the corrugated plates 16 are overlapped with each other, and wedges are driven into the communicating holes 20 for jointing. Furthermore, the whiskers of the growing vine can enter the holes 20 to stabilize the vine.

FIG. 6 shows the state in which the protective sheet 10 is used. The protective sheet 10 is spread on both sides of the upper surface of the ridge 26 covered with the vinyl film 24, and the seedlings that have been planted in the center of the ridge 26 are grown. 28 on the -F side of the protective sheet 10 to grow fruit vegetables 30 such as melons and watermelons.

Therefore, the growing fruits and vegetables 30 are supported by the corrugated plate 16 in which the convex ridge surface 12 and the concave surface 14 of the protective sheet 10 are alternately continuous, and grow with gaps on the lower surface. It has improved air permeability and light emitting properties, and is free from vinyl burn, rot, color loss, etc., and is grown as a high-quality fruit and vegetable.

Moreover, when the protective sheet 10 is formed of a transparent member,
When sunlight passes through, the ridges 26 are covered with the vinyl film 24 on the lower surface, raising the soil temperature. Effective for growth.

Since the protective sheet 10 is a corrugated plate 16, it can be easily rolled up and stored, and the fruits and vegetables 3 that have ripened can be easily removed from the ridges 26 without the need for removing the fruits and vegetables after harvesting.
Compared to the case where a pedestal is placed on the floor, it is possible to save labor in managing fruits and vegetables, and it can be stored compactly without being bulky when stored.

Moreover, the protective sheet 10 may be used as a pot sheet for pot cultivation of strawberries, flowers, etc., and in this case, it is effective in preventing root rot.

Although the fruit and vegetable locking portions 18 have the same shape and are arranged at regular intervals in the embodiment, the present invention is not limited to this, and they may be arranged with different shapes and intervals.
