Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention uses a long seedling mat that is longer than a conventional seedling mat and has a length of about 6 meters as a seedling for a rice transplanter. The present invention relates to a device for storing the long seedling mat before the planting.

[0002]

2. Description of the Related Art A conventional seedling mat for rice transplanters has a rectangular seedling mat having a width of 28 cm and a length of about 60 cm. However, in the rice transplanters etc.
With the conventional seedling mats, the seedlings quickly disappeared, and the operator had to turn around and splice the spare seedling mat onto the seedling mounting table, which frequently caused operator fatigue. Of. Also, in the case of conventional seedling mats, the number of sheets to be transported as spare seedlings increases,
Management and transportation were troublesome tasks.

[0003]

In the case of a long seedling mat, the root portion of the seedling is entangled with the bed soil as in the conventional case, and
With only one seedling mat, it is not possible to hold a long mat in one piece, and the seedbed part is cut during transportation or seedling raising. By using this long seedling mat, it is necessary to use a nonwoven seedling-raising sheet instead of soil in order to replenish the fact that the length of the mat becomes easier to cut and the length cannot be maintained.

The present invention makes it easy to store and store a long-length seedling mat when the long-length seedling mat solves the problem of increasing the number of seedling joints of the normal-length seedling mat. . The long seedling mat is as long as 6 meters, and is too heavy to store the long seedling mats in a stack in a usual manner. The present invention facilitates storage and transportation by rolling this long seedling mat into a spiral shape.

[0005]

The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described. The long seedling mat according to claim 1, wherein a seedbed sheet 4 is laid as a floor soil material inside the long seedling tray 1 and seeded on the seedbed sheet 4, and the seedlings are grown by hydroponic culture. The seedling mat is spirally wound and stored / transported as a long seedling mat M in a rolled state.

According to a second aspect of the present invention, in the long seedling mat storage device according to the first aspect, a storage cylinder U for carrying the rolled long seedling mat M is provided, and a caster is provided below the storage cylinder. The wheel W is provided.

According to a third aspect of the present invention, in the long seedling mat storage device according to the first aspect, the rolled long seedling mat M is enclosed in a synthetic resin bag Z, and the bag Z is sealed. The vegetation gas and the vegetation nutrient solution are injected into the inside of the.

According to a fourth aspect of the present invention, in a long seedling mat in which a seedbed sheet 4 is laid as a floor soil material inside the long seedling tray 1 and seeded on the seedbed sheet 4 and seeded by hydroponic cultivation, The long seedling mat is folded into two pieces, and the mats are locked and hung on the hanger rod Y for storage.
