Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an apparatus for growing rice seedlings.

[0002]

[Prior art]

 It is known that in order to produce paddy rice in a paddy field, it is necessary to grow paddy rice seeds to a certain extent by using a growing method in advance and then transfer them to the paddy field. As shown in FIG. 4, a conventional method for growing rice seedlings is to put a soil 50 containing a fertilizer into a dish 40 having a large number of drain holes 41 formed on the bottom surface, and then put the rice seeds into the soil 50. The roots of the rice seedlings 60 obtain nutrients by the fertilizer contained in the soil 50 and the water being supplied at regular intervals, and the rice seedlings grow. During the rice planting season, as shown in FIG. 5, the band-shaped soil 50 is taken out of the dish 40, and the rice seedlings 60 are taken out together with the soil 50 and transported to a rice planting machine (not shown). . When transporting the seedlings 60 to the rice planting machine, it is necessary to wind the band-shaped soil 50 slightly before transporting the seedlings 60 at a time, and thus transport the seedlings 60.

[0003]

[Problems to be solved by the invention]

 1. With the recent frequent development of land, the land at the mountain slope has been overdeveloped, has been considerably destroyed, and the loss of debris has reached a point of concern. It is important to select another medium for growing rice seedlings instead of the soil 50.

[0004] 2. The soil 50 is not solid, and it is inconvenient to carry when transporting. Further, the soil often falls during the transportation, and the seedlings 60 may fall together with the soil.

[0005] 3. It is necessary to go through a preparation process such as a crushing process, a softening process, a sorting process, and a fertilizer adding process of the mountain slope soil until the soil 50 where the seedlings can be grown is obtained. And the preparation time is uneconomical. In addition, there is a possibility that pests and their eggs may be contained in the soil 50. In such a case, the pesticides may be disinfected, and the pesticides may remain in rice cultivation.

[0006] 4. Although the seedlings 60 and the soil 50 are transported together, the weight of the transport is heavy, so there is considerable difficulty in transporting them. Further, since the soil 50 is easy to fall, cleansing after transportation is also a difficult task.

[0007] 5. Instead of soil, other growing media have been developed, such as a mixture of coconut shells and bark, or peat soil. However, since the source of the material is not widespread, the cost is much higher than that of the soil and the economic effect is not achieved. Therefore, there is a demand for a rice seedling growing apparatus that uses a growing medium that can reduce the cost and makes transportation more convenient.

[0008]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides a growth plate having a large number of through holes in the thickness direction to provide a growth space for the roots of rice seedlings, and a nutrient for growing rice seedlings. In order to allow the liquid to pass through, a number of through holes are provided on the bottom surface, and a mounting plate for mounting the growth plate, and a plurality of mounting plates formed at a predetermined depth for storing nutrient solution can be mounted. A seedling of paddy rice is sown on the breeding plate, and the roots of the grown rice seedlings are passed through the through holes and through holes to come into contact with a nutrient solution to obtain nutrients. The present invention provides an apparatus for growing rice seedlings, wherein the rice seedlings grow and the growing plate is made of cardboard.

The rice seedling growing device of the present invention uses a growing plate made of cardboard instead of soil. The cardboard used as the material for the breeding plate is made of recycled general used cardboard, which not only reduces costs but also makes it easier to obtain materials, and recycling waste is environmentally advantageous. It is. In addition, since the cardboard growing plate can maintain the shape of the plate while having flexibility, there is no danger of falling down like soil when winding, so that all seedlings can be retained during transport and even if transported roughly. No problem occurs. Therefore, transportation becomes very convenient.

[0010] In addition, instead of the corrugated cardboard, a paper plate formed by collecting and compressing paper debris and forming a predetermined size may be used as a growth plate.

Further, the paper plate may contain wood chips.

By including wood chips in the paper plate, a large number of through holes are naturally formed in the thickness direction of the plate, the step of providing the through holes in the plate can be omitted, and the cost can be further reduced.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[Embodiment of the invention]

 FIG. 1 is an exploded perspective view of a preferred embodiment of the present invention, FIG. 2 is a perspective view after assembling each member of the embodiment, FIG. 3 is a cross-sectional view of the embodiment, FIG. 4 is a cross-sectional view of a conventional growing method, and FIG. 5 is a schematic view of a transport state of the conventional growing method.

As shown in FIG. 1, the rice seedling growing apparatus of the present invention mainly includes a cardboard growing plate 10, a mounting plate 20, and a storage container 30. The growth plate 10 was placed on the mounting plate 20.

The growth plate 10 is provided with a large number of through holes 11 in the thickness direction in order to obtain a growth space at the root of the rice seedlings 60. In order to allow the nutrient solution 31 for growing the rice seedlings 60 to pass through, the placing plate 20 was provided with a large number of holes 21 on the bottom surface. The storage container 30 is formed at a predetermined depth to store the nutrient solution 31.

As shown in FIGS. 2 and 3, rice seeds are sown on the breeding plate 10, and the roots of the grown rice seedlings 60 are passed through the through holes 11 and the through holes 21 so that the nutrient solution 31 is formed. When they are brought into contact with each other, their roots can obtain nutrients and can extend through the through-holes 11, and the rice seedlings 60 grow.

The breeding plate 10 is made of cardboard, and the root of the rice seedling 60 is passed through the through hole 11. Further, since the roots are entangled with the bottom surface of the growth plate 10, even if the growth plate 10 is immersed in a liquid, the shape of the plate is not completely collapsed while being maintained. Further, since the cardboard growing plate 10 has flexibility, even if the soil is rolled and conveyed, the soil does not fall and the conveyance becomes convenient. Also, after the rice seedlings 60 are planted in the paddy soil with the rice planting machine, the cardboard made of the material for the growing plate 10 can be spoiled naturally and gradually, and furthermore, the cardboard and the soil have good fusion properties. In the soil of the paddy field, the rice seedlings 60 can also maintain a good growth state.

The following effects can also be achieved by using a paper plate formed of a predetermined size instead of the cardboard as a growth plate 10 by collecting and compressing paper chips.

When the paper dust has ink, the ink is removed together with the water by repeating the short-time immersion step many times, so that the ink is removed from the seedling 60 or the seedling. The adverse effect on the soil of the paddy field can be prevented.

[Effect of the invention]

 Since the present invention has the above configuration, the following effects can be achieved.

1. Conveyance is convenient and the shape of the plate can be maintained while the cardboard growing plate has flexibility, so there is no danger of soil falling when winding the soil as described above, and all seedlings are retained during transportation. It is possible, and no problem occurs even if it is transported roughly. Further, since no pests or eggs thereof are present on the cardboard growing plate, there is no problem of pesticide residues.

[0023] 2. The cardboard as the material of the growth plate has good water retention, and even if the seedlings are taken from the nutrient solution in the storage container, the nutrient solution held by the cardboard will continue to provide sufficient nutrients to the seedlings be able to.

[0024] 3. The cardboard used as the material for the breeding plate is made by reusing general used cardboard, which not only reduces costs but also makes it easier to obtain the material. Reusing waste is environmentally friendly. It is advantageous.

[0025] 4. The process consists of cutting the cardboard growing plate into a predetermined size and making holes without going through the conventional preparation process consisting of the steps of crushing, softening, sorting, and adding fertilizer to the soil of Yamasaka. A simple preparation process suffices, greatly reducing the cost and time of preparation.

[0026] 5. The good compatibility of the product with the soil after the corrugated cardboard, which is the material of the growth plate, has spoiled naturally, has no negative impact on the environment.

[0027] 6. Instead of the corrugated cardboard, paper scraps are collected and compressed, and a paper plate formed into a predetermined size is used as a growth plate. The through hole is formed, and the step of forming the through hole in the plate can be omitted, and the cost can be further reduced.
