Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a pot-type seedling grower for pulp raw materials.

(Objective) The object of the present invention is to obtain a pot-type seedling raising device that has a sufficient internal volume and allows for good growth.

Another object of the present invention is to provide a pot-type seedling growing device in which the top soil supplied between the pots swells and has good water absorbency, allowing efficient watering.

(Prior art) As described in Japanese Patent Application Laid-open No. 56-144017, a pot made of pulp, beet moss, natural fibers, and synthetic resin is made of a small trapezoidal pot when viewed from the side and placed on the bottom side. A large number of pot-type seedling growers arranged in a row in front, back, left and right are well known.

Furthermore, as described in Japanese Patent Application Laid-open No. 49-30128, a pot-type seedling growing device is known in which pulp raw material is scooped out on the inner surface of a wire mesh trapezoidal container and dried.

(Problems to be Solved by the Invention) In the former, disclosed in Japanese Patent Laid-Open No. 56-144017, the details of the inner and outer structures of the pot are not clear.

Furthermore, in the conventionally known method described in JP-A No. 49-30128, the pulp raw material is scooped out on the inner surface of a trapezoidal container made of wire mesh. A mesh-like smooth surface is formed by scooping, and an uneven surface is formed by solidifying the inner surface while being scooped. If the inner surface is uneven, the internal volume will not be sufficient, so in this known example, an inner mold is prepared separately and the method of shaping using the inner mold is used, which is cumbersome.

However, it would be more rational to form the outer surface of the pot into an uneven surface that is solidified after being scooped out, rather than a smooth mesh-like surface, and to form the inner surface of the pot into a smooth mesh-like surface. That is, if the outer surface is formed into an uneven surface, the top soil supplied between the pots will swell and become soft, improving its water absorbency and allowing efficient watering. By making the inner surface a mesh-like smooth surface, a pot-type seedling nursery with sufficient internal volume and good growth can be obtained.

In other words, it is preferable to use a configuration opposite to that described in Japanese Patent Application Laid-Open No. 49-30128.

(Means for Solving the Problem) Therefore, in the present invention, the inner surface 1a is formed into a mesh-like smooth surface formed by being scooped out by the outer surface of the mesh trapezoidal form 3, and the outer surface 1b is solidified while being scooped out. This is a pot-type seedling raising device for pulp raw material, in which pots 1 formed on an uneven surface are successively arranged in front, back, right and left on the bottom side.

(Example) An example of the present invention will be described with reference to the drawings.
is a pot exclusively for rice and wheat, with a base area of 1 cm ² to 3 cm ² and a height of about 1 cm to 3 cm, with a trapezoidal appearance.

The pot 1 may have a truncated pyramidal shape or a truncated conical shape, and in some cases, it may change from the bottom to the top.

Pot 1 has the same shape on the bottom side,
1... is connected in series to form a pot-type seedling nursery. A hole 2 is formed at the top of the pot 1.

These pots 1, 1, .
It is formed by scooping up the pulp solution and drying it, either as is or with optional detachment. Therefore, the pots 1, 1... have relatively smooth mesh-like inner surfaces 1a, 1a that are in close contact with the outer surface of the mesh formwork 3.
...and a highly uneven outer surface 1b that has been scooped up and left exposed to dry.

(effect) Next, we will discuss the effect.

In the seedling raising container formed as described above, place a thin layer of covering soil into each pot 1, 1, with the wide mouth facing upward, sow the seeds, and then cover the seedling raising box 4 with the bed soil. Turn the pots upside down, fill the gaps between each pot 1, 1, and so on with top soil and water.

In this case, the inner surfaces 1a, 1a of pots 1, 1...
is a mesh-like smooth surface that is scooped out by the outer surface of the trapezoidal mesh formwork 3, so the internal volume of the pot 1 is constant, the amount of supplied bed soil is uniform, and the growth of seedlings is smooth. It disappears.

In addition, since the outer surfaces 1b of the pots 1, 1, etc. are formed into an uneven surface that has solidified while being scooped out, the top soil supplied between the pots 1, 1 may get stuck on the uneven surface and become clogged. Because it is in a relatively swollen and soft state, it is rapidly absorbed when watered, allowing for efficient watering.

In addition, the structure of the outer surface 1b of the pots 1, 1, etc. is an uneven surface, so there is no crushing, and since it is not in a press-like high-density form, it has good water absorption and is difficult to dry out, making it possible to reduce the frequency of watering. .

Furthermore, even if the watering work is delayed and the pots dry out, since the outer surfaces 1b of the pots 1, 1... are uneven, it is difficult to form gaps between the pots 1, 1... and the top soil. The inside of 1, 1... does not dry out, and there is no problem with growth.

(Effects) In the present invention, the inner surface 1a is a mesh-like smooth surface formed by being scooped out by the outer surface of the trapezoidal mesh formwork 3.
Since the outer surface 1b is a pot-type seedling raising device for pulp raw material in which the pots 1 formed on the uneven surface that are solidified while being scooped out are connected in a row from front to back and from side to side on the bottom side, the inner surfaces 1a of the pots 1, 1... Since 1a is a mesh-like smooth surface formed by scooping out the outer surface of the net trapezoidal form 3, the internal volume of the pot 1 is sufficient and constant. Therefore, the amount of soil supplied to the bed is sufficient and uniform, and the seedlings grow well and without spots.

The outer surfaces 1b of the pots 1, 1... are formed into uneven surfaces that have been solidified while being scooped out, so
The top soil supplied between pots 1 and 1 is hard to get stuck on the uneven surface and is in a relatively swollen and soft state, so it is rapidly absorbed when watered, resulting in good water retention and easy irrigation. .

The structure of the outer surface 1b of the pots 1, 1... is an uneven surface, so there is no blindness, and since it is not a press-like high-density structure, it has good water absorption and water retention properties, and the frequency of watering can be reduced. .

Even if the watering work is delayed and the soil dries, the outer surfaces 1b of the pots 1, 1... are uneven, so that gaps are unlikely to form between the pots 1, 1... and the top soil.
Therefore, the insides of pots 1, 1, etc. do not dry out, and growth is not hindered.

This effect is achieved.
