The present invention relates to an improvement of a method for producing seedlings, and more specifically, a port unit containing a plant growth accelerator, and an adjacent port unit may be naturally separated into unit units when the seed is close to the transplanting time after germination. After transplantation, the present invention relates to a method for producing a seedling pot having a structure that is completely rotten and manure and the port is foldable and thus convenient to package and store.

The seedling method of planting seeds to germinate and nurturing the pot has many advantages over the conventional method of directly planting seedlings in rice fields and then removing the soil and transplanting it to the farmland.

For example, the roots are effectively protected during transplantation and are easy to transplant. That is, in the conventional method, when the seedling is to be planted from the seedling to the arable land, the seedlings are removed together with the clay so that the roots of the shoots are not damaged, then they are bundled together so that the clay does not fall from the roots, or paper or vinyl It was wrapped in a back and transported to a farmland.

This conventional method has a very bad root, and the work is also very cumbersome in the process of transferring the shoots grown in the nursery.

In view of such a situation, it is the pot seedling method that appeared. Seedling cultivation by pot is, as mentioned above, beneficial for transplanting seedlings but there is much room for improvement.

Conventional seedling pots were mostly made of synthetic resin, and only a part of them were used to make an envelope-shaped pot from waste paper.

Since the resin or paper is buried in the ground, it does not rot and interferes with the formation of capillaries between the main fabric and the drainage.

Conventional pots also need to be released from the pots once they are sown, so in general, the components of the pots are naturally separated when vomiting or when transplanted by pushing the bottom of the pots with fingers. When separated, part of the roots of the shoots were lost.

These pots are further improved because they protect the roots of sprouted seedlings more securely, do not need to be harvested easily and efficiently after harvest, and do not meet the expectation that they will be buried and rotting and oiled with the soil as it is. An improvement was required.

The present inventors easily rot when they are buried together with the shoots when transplanting, the rotten becomes manure, and the unit port (unit) is planted with seeds, and when transplanted, the water-soluble adhesive at the adhesive site is dissolved in water, and the adjacent ones are separated from each other. It contains a growth accelerator, which greatly helps seed germination and growth after transplantation. In addition, the pot where several units are folded becomes a small volume when folded, and it is easy to pack and store. As a result of the study, the present invention has been completed.

That is, the cleansing of the port unit of the present invention mixes 10-15 parts of cationic starch with 100 parts of fiber (cellulose) in a fiber suspension, thereby making it possible to use anionic wood pulp cellulose. And 2.7 parts of the low-polymerization cationic urea was mixed with 100 parts of the above-described cellulose, and 0.2 parts of sodium silicate was added thereto to fix the urea resin at the same time immediately before the formation of the marsh. PH is adjusted to 7-8 to form wet peel in alkaline.

The characteristic of the unit material completed by this method is that it has good stiffness as an alkaline paper material, contains sodium silicate and starch, and has the stiffness of the paper. -strength) is stably maintained at 20-25% as well as rich in permeability and permeability due to starch sizing, while having high wet strength to create a good environment for aerobic bacteria to grow, thereby fertilizing soil at the root part Promotes

In addition, the seed drainage is reduced by smoothing the water drainage phenomenon of the soil, the germination rate is high, and starch contained in cellulose decays and promotes buffing of cellulose.

In addition, the above-mentioned phenomenon is that by using the depolymerized urea resin, the residual urea resin is used to promote the plant growth by improving the soil, since the acidic soil is converted into alkaline soil along with the elution of the alkaline ingredients and the buffet. .

Each unit made of such materials consists of a pipe model with a completely open top and bottom of a certain shape, for example triangular, square or hexagonal.

The units are not irrigated, but are formed by a method in which adjacent surfaces are joined together by adhesives continuously in front, rear, left, and right to form a port, and the bottom plate supporting the bottom of the unit and the outer insulation in the unfolding direction ( Unlike the geology of the unit, the side plate supporting the outer surface of i) is formed of a material that is resistant to water or moisture, and contains no harmful ingredients such as synthetic resins and Fuji treated with harmless fat.

In order to form a unit, it is cut to a certain size, and a bend line is given in the transverse direction of the cut material as a method for achieving the surface accurately and uniformly. The number of fold lines is equal to the number of sides of the unit to be formed.

The adhesive used for joining the first and last surfaces to form a tubular shape, among which the different surfaces are formed at the boundary of the bend line in one unit, is a water-resistant adhesive, so that the joint surface of the unit until transplantation is performed. The loosening can be prevented from breaking up and dispersing.

However, after some time of transplantation, it is good to melt and be absorbed into the soil. That is, the rate of dissolution in water is slightly slower in time than the general water-soluble adhesive rather than a completely water-resistant adhesive.

Water-soluble adhesives are used for bonding the unit. When transplanting the appropriately grown shoots after sowing, the units that have been planted together with the unit, which have been united as a unit, have to be separated separately, so that the unit and the unit can be easily separated to facilitate the separation of these units. Should fall.

For this reason, the unit-to-unit bonding requires a water-soluble adhesive. Water soluble adhesives are, however, subject to conditions that will allow them to remain bonded for some time.

The reason for this is that when the seeds are sprouted in the unit and germinated, three or four leaves emerge, and the period is not constant depending on the season, the soil, the type of plants, etc., but it usually takes about 40-60 days after planting.

Therefore, the state of bonding with water-soluble adhesives needs to last for at least one month, which can be transported when transplanted.

The water-soluble adhesive as described above is also used for the joining between the unit and the side plates positioned in the left and right side end rows toward the unfolding.

The bottom plate and side plate that protect each unit and the unit in the left and right row in the direction of deployment are a unitary unit, and the bottom plate is formed in the same size as the plane consisting of a set of deployed units, and the drain hole of the bottom plate is for each unit. Consider being assigned more than one.

As such, the seedling pot completed by the present invention is beneficial to transfer the unit to the mainland with the topsoil when transplanted and rotted to make manure necessary for plant growth, and also to prevent the damage of the roots due to the scattering of the topsoil during transplantation. When compressed and folded, the volume is significantly reduced during deployment, so that the convenience of packaging, transportation, and storage can be obtained.

Hereinafter, the manufacturing method of the present invention will be described in detail with reference to the accompanying drawings based on the embodiments.

[Step 1]

Composition of Port Unit Material

By mixing 13 parts of catchonized starch with 100 parts of fiber suspension, 2.5 parts of low-polymerization catchable urea resin with a low degree of polymerization of 100% fiber immediately before wetting the starch into the anionic wood pulp fiber by ion bonding. Mix with and 0.18 parts of sodium silicate to fix the urea resin.

At this time, the concentration of pulp suspension (pH) was adjusted to 7 to form alkaline paper, and then coated on the surface of the mixture of lime silicate and plant growth promoter in a ratio of 3: 1 at a density of 20 g / m ² and wound up. It is wound up on a roll and made of a winding unit material (p).

Second Process

Manufacture of unit

As shown in FIG. 5, a bend line for dividing the surface of the raw material p obtained by the first process by the roll 7 of the bending line forming line of the processing machine is provided, and then the adhesive material is also a pintain roll ( In 8), the water-resistant adhesive 5 is applied on the outer surface to be the first surface 4 of the unit 4 and dried by passing through the dryer 9 once.

The remaining surfaces 4a to 4g of the material are coated with the rotary roll 10 on the water-soluble adhesive in another adhesive application line. In this process, restrictions are applied to the coated surface.

That is, in Fig. 1, a completed honeycomb port is shown. Referring to this figure, both ends of the upper and lower "end" ports (in Fig. 1, the horizontally arranged unit units are referred to as "ends", Unit units arranged vertically are denoted by " columns. &Quot; Fig. 6 is a unit 41 located in the " stage " in the waterline direction and " columns " , (42), (43) and (44) materials are not attached to the side plates (3) and (3 '), but the top and bottom "ends" of the unit material and center "ends" except for the two sides touching the adjacent unit. The unit material to be positioned at both ends is located on both sides of the second "end" and the fourth "end" from the top of the four sides, which are all sides to be contacted. All of the unit 49 material is adhesive is applied to the front surface of all the contacted.

The water-resistant adhesive 5 has already been applied to the first surface 4 of all the materials to be the unit.

The surface on which the water-soluble adhesive 5 is coated with the water-soluble adhesive is the same as the outer surface of the unit material.

However, after the water-soluble adhesive is selectively applied depending on where it is located, the dryer 12 is introduced into the bending device 13 of the bending line.

In this bending apparatus 13, it is bent so that the side by which the adhesive agent 5 of the 1st surface 4a of the raw material of the unit 4 was apply | coated, and the side which the adhesive agent of the 7th surface 4g was not applied and abut may overlap.

After the bending is completed, the first unit 4a and the seventh surface 4g are assembled while passing through two press-contact rolls 14 having a heating device, and the compression unit tube 15 before the extrusion is rolled. To form.

More specifically, as shown in FIG. 1, a polypropylene plate having a thickness of about 1 mm is formed on the left and right sides when the regular hexagonal unit 4 aggregates 5 and 5 " columns " The outer surface of the outer unit is the width of the bottom plate, and the bottom plate 2 is formed with the drainage holes 6 and the bent side pipes 3, 3 'such as the height of the unit, and the vertical bend line 16 at the center of the bottom plate.

[4th process]

Completion of the port

The unit materials are press-bonded by laminating and heat-pressing the n unitary compressed tube 15 in the compressed state before the cutting in the second process in the same manner as in FIG.

This will be explained in more detail in the first six-degree first " row " unit tubes 15-1, 15-3. They are arranged with a distance S on one side of the hexagonal unit and are arranged in the second "row" unit tube 15-2. They are arranged such that one side of the hexagon is located between the above-mentioned distances S and such an arrangement is arranged as "rows" (15-n) as necessary.

That is, as shown in FIG. 1 of the present invention, six "columns" of two 7 "columns" are alternately arranged. This arrangement is continuously pressed by a heating press roll (not shown) to complete the honeycomb-shaped pot before cutting and cutting it to a suitable length, for example, to the height of the side plates 3, 3 'of FIG. As shown in FIG. 2, the honeycomb seedlings can be compressed and used to expand the bottom plate and the side plate.
