Description

[Detailed description of the invention] Industrial application field The present invention relates to a seedling raising device.

Prior Art Conventional seedling raising devices are made of resin, and their manufacturing method employs press molding of male and female shapes.

Problems to be Solved by the Invention When manufacturing a seedling raising device using paper, the method for manufacturing a resin seedling raising device cannot be adopted because the dissolved waste paper, which is dissolved in water, does not solidify rapidly. Also, even if a seedling pot is manufactured using a similar manufacturing method, both the inner and outer walls of the seedling pot will be smooth.
It has poor water absorption and is unsuitable for raising seedlings.

Means for Solving the Problems In order to solve the above problems, the present invention provides the following:
The following manufacturing measures were taken.

That is, in the present invention, a waste paper solution containing old newspapers and the like is applied to the outer surface of a mesh frame 4 in which trapezoidal pots with projections 5 protruding from the center of the top portion are lined up front and back and left and right. This is a method for producing a pot-type seedling nursery made of waste paper, which is produced by scooping up the waste paper and removing the waste paper attached to the outer surface of the net-forming frame 4.

Effects of the Invention According to the present invention, a waste paper solution containing old newspapers, etc. is dissolved in a mesh forming frame 3 in which trapezoidal pot-shaped pots with protrusions 5 protruding from the center of the top portion are lined up front and back and left and right. Scoop it up in a form that adheres to the outside surface,
Since it is manufactured in the form of paper-making, pot-type seedlings can be easily manufactured using recycled paper.Moreover, the inner surface 1a of the seedlings-raising pot is smooth, and the amount of bed soil for raising seedlings is uniform, so that the growth of seedlings is uniform during raising. , the outer surface 1b is uneven, increasing the surface area and increasing water absorption.
Since the manufacturing mold is provided with a protrusion 5 for forming a hole for germination, it is possible to form a predetermined hole 2 at the center of the top of the seedling growing pot.

Example First, let me explain the structure of this pot-type seedling raising device A made of waste paper.The floor area is about 1 to 3 cm ² and the height is 3 cm.
The upper edges of the pots 1, which are shaped like a truncated pyramid with a trapezoidal shape when viewed from the side, are continuous with each other, and each pot 1 has a hole 2 in the center of its bottom. If you take out a part and show it upside down, it is the first part.
It is as shown in the figure. As shown in Figure 2, the overall size is 60 cm in height and 30 cm in width.
It is sized to fit into a seedling growing box 3 having a size of cm.

Next, to manufacture this pot-type seedling nursery A,
A mesh forming frame 4 as shown in FIG. 3 is used. This net forming frame 4 has a net 4a made of metal in the same shape as the pot-type seedling grower, and a protrusion 5 separate from the net is integrally provided at the center of the bottom surface.

Then, a waste paper solution obtained by dissolving so-called waste paper such as newspaper or cardboard (usually dissolved in water) is scooped up onto the outer surface of the mesh forming frame 4 and deposited to a predetermined thickness. This state of adhesion is shown in FIG. 4, where only the waste paper is deposited on the surface of the net-forming frame 4 without being filtered, and the liquid flows down from the screen.
At this time, waste paper does not adhere to the protrusion 5, and this portion forms the hole 2. After draining the water in this state, the adhering waste paper and the frame 4 are separated to obtain a pot-type seedling raising device A as shown in FIG.

Pot-type seedling raising device A manufactured in this way
In this case, the inner surface 1a side that is in close contact with the mesh forming frame 4 is smooth with almost no unevenness, but the outer surface 1b side is a pox-scarred surface with severe unevenness. In particular, the unevenness becomes severe at the valley bottom between the pots 1, 1.

To raise seedlings in the pot-type seedling raising device A manufactured in this way, place the seedling raising device A on a board with the mouth side facing up, and add a little soil (covering soil). After sowing the seeds, filling them with bed soil and covering them with seedling raising box 3, turning them upside down, removing the upper board and watering to manage the seedlings, the seedlings will grow as shown in Figure 6. .

At this time, the inner wall surface of the seedling-raising pot is formed smoothly, so the amount of bed soil is constant and seedling growth does not occur, and the outer wall surface is formed with a rough, pox-scar-like uneven surface, so the surface area is The area becomes wider and absorbs water very well, making it possible to grow seedlings with just a short period of watering.
