Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a plant cultivation bag, and more particularly to a plant cultivation bag formed of a synthetic resin such as a polyethylene resin or a vinyl resin.

[0002]

2. Description of the Related Art Conventionally, bag-type plant cultivation tools of this type include, for example, one having a drainage opening formed at a lower portion and an opening formed at an appropriate position on a peripheral surface to allow the buds of a plant to emerge. JP-A-59-70444 and JP-A-59-83331), those equipped with soil (see Japanese Utility Model Publication No. 2-28687), or those provided with an irrigation reservoir according to the proposal of the present applicant. (See Japanese Utility Model Publication No. Hei 7-26920).

[0003]

By the way, this kind of cultivation bag is not only capable of easily performing temperature control such as heating and warming, humidity control, etc., but also used in large quantities, and is inexpensive. It is desirable that the device be formed so as to facilitate manufacturing and reduce manufacturing costs.

[0004] However, the conventional product is obtained by subjecting a bag having an open top surface whose periphery is completely sealed to a desired processing. Therefore, according to the conventional product, it is only possible to control the heat retention, moisture retention, etc. from the opening on the upper surface, and in terms of production and cost, it is necessary to process the bag and drill the drain hole. The costs were inevitable.

[0005] In the conventional product, when a grown seedling is transplanted from a bag, since this kind of bag is made of resin and is not easily broken, an operator first turns the bag together with the seedling and then pulls the bottom of the bag. Had to be removed from the seedlings. Therefore, when a conventional product is used, it is cumbersome and inconvenient when transplanting seedlings.

[0006] The present invention has been proposed in view of such problems of conventional products. Therefore, the technical problem of the present invention is to not only simplify and simplify the temperature management and humidity management, but also to make it suitable for automation of production and mass production, thereby making it possible to reduce the cost. Container, simple,
An object of the present invention is to provide a plant cultivation bag formed so as to be easily removed.

[0007]

The present invention employs the following technical means in order to solve the above-mentioned problems.

That is, according to the present invention, as shown in FIG. 1, two resin sheets 1 are polymerized and the left and right side portions 2
The upper part 3 and the upper side part 3 are opened, and the other peripheral parts 4 are spot-welded at regular intervals (claim 1).

Here, the resin sheet 1 includes polyethylene resin, vinyl resin and the like. Two resin sheets 1
Are preferably selected to have the same size and the same thickness, but the present invention is not limited to this.

Usually, the resin sheet 1 is preferably formed in a transparent state, but may be colored in black or the like by kneading a black paint or the like with a resin liquid. Also, the two resin sheets 1
It is not necessary to use the same sheet of, for example, polyethylene resin. For example, a sheet of polyethylene resin and a sheet of vinyl resin may be combined. The present invention
Since two resin sheets 1 are polymerized and spot-welded at a predetermined position in this manner, there is an advantage that each resin sheet 1 can be selected and manufactured optimally according to cultivation conditions.

In the case of the present invention, the interval between the welding points 5 is arbitrary. If this interval is selected widely, for example, drainage is improved, and when transplanting a grown seedling, the operation of peeling off the two resin sheets 1 can be easily performed. However, on the other hand, the water retention deteriorates, so in the case of the present invention, the interval for spot welding may be appropriately selected according to the size and shape of the bag, the type of seeds and seedlings, and the type of soil.

Further, according to the present invention, as shown in FIGS. 5 and 6, instead of polymerizing two resin sheets 1, one resin sheet 1 is folded and the folded portion of the resin sheet 1 is The left and right sides 2 may be spot-welded at regular intervals by forming the bottom 10 and opening the upper part of the left and right sides 2 and the upper side 3. .

[0013] In this case, the number of welding points 5 can be reduced, so that it can be manufactured simply and easily, and at the time of transplanting grown seedlings,
When the upper side portion 3 of the bag is peeled off, it is connected via the bottom side portion 10, so that the bag is not completely separated. Therefore, according to this, there is an advantage that scattering of the resin sheet 1 can be prevented, and the resin sheet 1 is easily disposed. In addition, 5 is a welding position.

As shown in FIGS. 7 and 8, the plant cultivation bag of the present invention is obtained by folding one resin sheet 1 instead of polymerizing two resin sheets 1, Is turned to one side 2a, and
The other side 2b and the bottom 10 may be spot-welded at regular intervals by opening the upper part of the other side 2b.

In this case, as in the case of the embodiment shown in FIGS. 6 and 7, the production can be facilitated, the scattering of the resin sheet 1 can be prevented, and the drainage and water absorption from the bottom 10 can be performed. There is an advantage that water retention and moisture retention can be easily managed. In addition, 5 is a welding position.

[0016]

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

In the present invention, as shown in FIG. 1 and the like, two resin sheets 1 are polymerized, and the upper part of the left and right side parts 2 and the upper part 3 are opened to form another peripheral part 4. Are spot-welded at regular intervals.

In the present embodiment, the resin sheet 1 is made of a transparent polyethylene resin having the same thickness and has a rectangular shape.

Reference numeral 5 denotes a spot welded by spot welding.
In the case of this embodiment, the welding point 5a at the uppermost end of the left and right side portions 2 is selected at a position slightly above the center of the bag, and is formed so that the left and right side portions 2 are largely opened. .

Next, an example of use of the cultivation bag of the present invention of this embodiment will be described with reference to FIG. The operator first puts the soil 6 (see FIGS. 2 and 3) to a position below the uppermost welding point 5a, and then stores the product of the present invention in a container 7 (see FIG. 10) containing water. Let it. The product according to the present invention is provided with the welding points 5 adjacent to each other.
Is formed in the opening 8. Therefore, the water in the container 7 permeates the soil 6 from the opening 8.

Next, the worker takes out the product of the present invention from the container 7 and drains excess water contained in the soil 6 from the opening 8 naturally.

Thereafter, the worker inoculates seeds or seedlings and stops the left and right positions of the upper part of the bag with a stapler needle 9 if necessary for heating and keeping warm. However, if the temperature is high, this type of stapling is not required to prevent high temperature damage in the bag after sowing or planting seedlings. The stapling position is as shown in FIG.
It may be better than both ends of the bag. When the seedlings have grown and reached the stapled top, remove the stapler needle 9 and open the top. Water supply during seedling raising is performed by opening the upper part of the bag, but it is also possible to immerse the whole bag in a water tank.

According to the present invention, convection occurs when the temperature of the internal space rises, regardless of the presence or absence of the stapler on the upper portion of the bag, and warm air is released from the upper side 3. In addition, since outside air enters from a gap between the side portions 2 near the uppermost welding point 5a near the surface layer of the soil 6, the temperature and humidity of the internal space can be easily controlled.

When transplanting the grown seedlings, first, the upper sides 3 of the two resin sheets 1 are gripped and pulled so as to separate them from each other. Thereby, the resin sheet 1 is peeled off from the welding location 5. Then take out the seedlings in this state,
It is planted on a new nursery and the resin sheet 1 is discarded.

[0025]

As described above, according to the present invention, the two resin sheets are polymerized, and the upper and upper sides of the left and right side portions are opened, and the other peripheral portions are spaced at a constant interval. Spot welding.

Therefore, when the present invention is used, not only can the cultivation environment such as temperature control and humidity control be easily and easily created, but also the production, automation and mass production are easy, so that the product can be provided at low cost and the resin sheet can be provided at low cost. The seedlings grown by peeling off the seedlings can be taken out of the bag, so that the work of taking out the seedlings at the time of transplantation can be performed simply and easily.
