2. Description of the Related Art As a seedling cultivation container for growing herbaceous seedlings or woody seedlings, a small lightweight container in which a black synthetic resin film is molded into a flowerpot has been generally popular. A trader sells cultivated seeds, fertilizers, etc., sown or seedlings grown in this container and grown to a certain size at a horticultural store. Consumers purchase seedlings or seedlings in this state (hereinafter abbreviated as seedlings) and transplant them in fields, planter boxes, flower pots, etc., but at this time, the seedlings must be removed from the seedling cultivation container and replanted. First, the used container is incinerated.

As a peculiar cultivating container, the actual Kaihei 2-13
"Folding cultivation container" proposed in Japanese Patent No. 7842

This cultivation container serves as a planter box as it is, and it is disclosed that the far-infrared ceramic sheet is used to enhance the growing effect, but the purpose and the configuration are different from the seedling cultivation container of the present invention. is there.

[0004]

The above-mentioned container that has been widely used in the past is a container that is simply formed by molding a synthetic resin film and is used for growing seedlings so that it can be transplanted. Since it is a container that is stable, impermeable, and non-rotable, it cannot be transplanted to fields, planter boxes, etc., and the seedlings must be removed from the container and replanted. Therefore, when removing it from the container,
Fine roots, which were densely and densely packed in the culture soil, were often released from the culture soil, so that there were drawbacks such that growth after transplantation was impaired, and serious death occurred. Furthermore, since the used containers are incinerated, they were also a source of pollution.

The present invention eliminates such drawbacks of conventional containers, further improves the growth effect, and enables transplanting as it is as a seedling cultivation container, and is excellent in water permeability and air permeability, and within a desired period. Moreover, the purpose of the present invention is to provide an inexpensive seedling cultivation container which is rotted and serves as compost by itself, and naturally does not cause pollution due to incineration.

[0006]

As a material for forming the seedling cultivation container of the present invention, a sack cloth woven from jute stem fibers of jute, which is a plant fiber, is used. This sackcloth is a material cloth to be used for bags such as so-called Nanjing bags that store grains and the like, and is usually made of semi-bleached yarn or woven fabric. In general, jute is another hemp,
Compared to cotton, etc., it is particularly weak against alkalis, and its dye easily binds to chlorine in the bleaching powder used during semi-bleaching, so it has the property of being weakened by the action of sunlight, air, and moisture. Is cheap.

In the present invention, a semi-drifted jute sack cloth is used as a raw material.
Carboxymethyl cellulose (hereinafter abbreviated as CMC), vinyl acetate resin, starch paste, poval, etc. are dispersed in an alkaline organic binder prepared by mixing according to a predetermined combination, and the jute sack cloth is padded with this liquid. Alternatively, the material cloth is coated with a liquid and dried to be finished to an appropriate hardness, prevents fraying of the rough cloth, and becomes a material cloth having water permeability and air permeability in which far-infrared radiation ceramics are dispersed and fixed. The far-infrared radiation ceramics are preferably ceramics containing alumina or zirconium as a component, and by using 3 to 5 weight% of fine powder of 3 to 5 microns, the growth of seedlings can be further promoted.

The present inventor paid attention to the above-mentioned properties of jute and, as a result of repeating experiments over a long period of time, as a result
It was confirmed that the period from transplanting to a planter box or the like until the container rots can be predicted by selecting the mixture of the binder and adjusting the PH throughout the four seasons (using the gardening house only in winter).

The molding of the seedling cultivation container of the present invention will be described with reference to the drawings. As shown in FIG. 1, the processed material cloth is first provided with a notch 6 below the right side 5, and three notches 7 are formed at regular intervals in the vertical direction from the bottom 3.
Cut it into a fan shape. When the bottom surface forming portions 8, 9, 10, 11 of the fan-shaped cloth 1 are sequentially folded in the front direction as shown in FIGS. 2 to 3 and are overlapped with each other, the right side 5 passes through the cutout portion 6 on the lower right side, and the right side 5 becomes the left side. Since they overlap with each other, when the overlapped portions are attached by, for example, a stapler or an appropriate adhesive means, a round-shaped round-shaped flowerpot-shaped seedling cultivation container having a square bottom and a circular top is formed very easily.

[0010]

Example 1 A jute sackcloth that had been semi-bleached in advance was used as a formulation example 1.
After passing through a padding machine with a 3-ball mangle containing the room temperature bath solution, squeeze it to 100% of the pick-up, and immediately dry it with a pin tenter dryer at 100 degrees Celsius (see Fig. 6), the appropriate tension and firmness The material cloth for molding the seedling cultivation container of the present invention having the above is obtained.

This material cloth is cut into a partially cut fan-shaped cloth 1 shown in FIG. The upper side 2 and the bottom side 3 of the fan-shaped cloth 1 form a gentle arc-shaped parallel line, and the lower side of the right side 5 is cut out in a strip shape. Then, by making cuts 7 from the bottom side 3 at equal intervals in the vertical direction, the bottom surface forming portions 8, 9, 10, 11 having a reverse trapezoidal shape separated into four pieces are defined. The size of the notch 7 is equal to the bottom of each section, and the lengthwise dimension of the strip-shaped notch 6 on the right side 5 is equal to the length of the notch 7, and the length of the notch 7 is left and right. About 30% of the side length is suitable.

The bottom surface forming portions 8, 9, 10 and 11 of the fan-shaped cloth 1 cut as described above are sequentially bent toward the front as shown in FIG. 2 and overlapped with each other, and if necessary, stapled, and the right side 5 Since the right side overlaps with the left side 4 through the lower cutout 6, by attaching the overlapped places with a stapler at two or three places, the bottom shown in FIG. The seedling cultivation container of the present invention having a flowerpot shape is formed. By the way, the dimensions of the fan cloth 1 are
Top side 225, bottom side 135, left side 110, right side 75
Rabbit + 35 r = 110 gr, 15 grit in the transverse direction of the notch, 3 cuts
When cut into 5 pieces, the bottom of the molded container is 35 pieces x 3 pieces.
The plant is a round open type seedling cultivation container having a square shape of 5 puffs, a height of 75 puffs and an upper surface having a diameter of about 65 puffs.

When the seedling cultivation container molded as described above is filled with culture soil, fertilizer, etc., and sown or seedlings are grown to grow seedlings, the seedlings are grown by the action of far-infrared ceramics dispersed and fixed in the container itself. Is promoted. As shown in FIG. 5, seedlings grown to an appropriate size were transplanted into soil such as fields and planter boxes together with the containers, and in the case of Example 1 using the bath solution of Formulation 1, it took about 1 year. After 6 months, the container rotted and composted.

As described above, the cause of the decay of the container in the soil is that the dye in the fiber is combined with chlorine when it is semi-bleached with the chlorine-based bleach together with the property that the jute is weak against alkali, resulting in sunlight. , It has the property of becoming brittle due to natural effects such as air and water. Therefore, the duration of decomposition and embrittlement is controlled by adjusting the type of binder that makes up the processing liquid and the pH of the bath liquid, and in addition to the heat of far infrared rays. It is considered that it is due to the effect and the additive effect such as the decomposition action by bacteria in the soil. In the case of the present embodiment, if it is desired to further shorten the decay period, the purpose is achieved by gradually decreasing the urethane resin and increasing the CMC by the amount of the decrease. For example, if the urethane resin was halved and the CMC was increased by that amount, the decay period could be shortened to about 10 months.

Formulation Example 1 Urethane resin (40% liquid) 20 parts CMC (10% liquid) 50 parts Far-infrared radiation ceramics (alumina type, particle size 5 micron) 3 parts Water 27 parts The above mixed solution is caustic soda solution. Adjust to PH8 and use.
