Description

  TECHNICAL FIELD The present invention relates to a winding cloth for straw cultivation, and more particularly to a winding cloth for straw cultivation suitable for artificial cultivation of enoki mushrooms.

  The artificial cultivation of enoki mushrooms uses a cultivation bottle with a bottle mouth of a predetermined size on the upper side, and after cultivating this cultivation bottle with a medium, inoculated with enoki mushrooms and cultured in a predetermined atmosphere. It is done by germination and growth. In this bottle cultivation, wrapping paper is wound around the bottle mouth in a cylindrical shape so that the enoki mushrooms extend straight.

  This wrapping paper has a length that slightly rounds the bottle mouth and the ends slightly overlap each other, and has a substantially fan shape as a whole, and can be detachably attached to the bottle mouth. For attachment to the bottle mouth, there are a method of winding a wrapping paper around the mouth of the bottle and hanging a rubber band from the outside, and a method of using a stopper such as a clip or a stapler instead of the rubber band hook. However, both of these attachment methods require the work of removing the rubber band, clip and stapler in addition to the work of removing the wrapping paper, which increases the work man-hours and makes the work cumbersome. It is also necessary to manage the equipment. In addition, since the wrapping paper is used in a humid cultivation environment, if the clip or stapler is made of iron, it will rust due to water wetting and fall off from the bottle mouth or adhere to the rusted wood and reduce quality. There are issues such as inviting.

  Therefore, recently, a wrapping paper has been developed in which a hook-and-loop fastener is used instead of these stoppers, and the hook-and-loop fastener is bonded to a wax paper with an adhesive or thread-sewn. The wrapping paper using the surface fastener is easier to attach and remove the wrapping paper than other methods. However, the wrapping paper using the hook-and-loop fastener is generally made of wax paper, and the hook-and-loop fastener is adhered or thread-sewn to the wax paper. There is a problem that the hook-and-loop fastener is easily detached from the wax paper due to damage or a decrease in adhesive strength. A wrapping paper devised to solve this problem is disclosed in Patent Document 1 below.

  Hereinafter, with reference to FIG. 5, a wrapping paper disclosed in Patent Document 1 below will be described. 5 shows a wrapping paper disclosed in Patent Document 1 below, FIG. 5 (a) is a front view of a state in which a through hole is formed in the wrapping paper, FIG. 5 (b) is a plan view of a hook-and-loop fastener member, and FIG. (C) is sectional drawing of a hook_and_loop | surface fastener member.

  The wrapping paper 20 for cultivating is a fan-shaped wrapping paper (base material) provided with through holes 22a and 22b for fixing the hook-and-loop fasteners 16a and 16b at both ends in the longitudinal direction, and a hook-and-loop fastener member fixed to these through-holes. 24a and 24b, and the surface fastener 26 and the adhesive support sheet body are thermocompression-bonded via a thermosetting adhesive. The hook-and-loop fastener is attached using a pair of hook-and-loop fastener members 24a and 24b (see FIG. 5C), and these hook-and-loop fastener members 24a and 24b are bonded to the through holes 22a and 22b of the wrapping paper. For these adhesions, first, the hook-and-loop fastener members 24a and 24b are folded in two across the line A, and are folded so as to straddle the lower end edge of the wrapping paper 20, and are bonded to the front and back surfaces of the wrapping paper 20. At this time, since the through-holes 22a and 22b are provided in advance in the site where the surface fasteners 16a and 16b of the wrapping paper 20 are bonded, the through-holes can be obtained by pasting the surface fastener members 24a and 24b from the front and back surfaces of the wrapping paper 20. At the portions where 22a and 22b are formed, the sheet bodies 26 of the hook-and-loop fastener members 24a and 24b are directly bonded to the front and back surfaces. FIG. 5C shows a state in which the hook-and-loop fastener member 24a is attached to the portion of the wrapping paper 20 where the through hole 22a is provided. That is, the hook-and-loop fastener member 24 a is folded in half, and the sheet body 26 is bonded to both sides of the wrapping paper 20, so that the hook-and-loop fastener 16 a is supported by the wrapping paper 20. According to this attachment, the through-hole 22a is provided in the wrapping paper 20, and the surface fastener 16a is bonded so that the front and back surfaces of the wrapping paper 20 provided with the through-hole 22a are sandwiched between the sheet bodies 26 of the surface fastener member 24a. The sheet body 26 is securely bonded integrally at the portion provided with, so that the hook-and-loop fastener 16a is not peeled off and detached from the wrapping paper 20.

  In addition, the wrapping paper determines the quality of enoki mushroom cultivation in bottle cultivation, and its characteristics are important. If the wrapping paper to be used is, for example, one with poor air permeability, the enoki mushrooms that are grown tend to become mushrooms, and conversely, if the air permeability is good, they become easy to dry and hinder growth. In addition, if there is no smoothness, the growth of the side branch in contact with the wrapping paper may be hindered, and the same growth may be hindered. And as for the conventional wrapping paper, the wax paper which apply | coated the wax (wax) on the surface of the paper material which has air permeability is used like the wrapping paper of the following patent document 1. FIG. This wax paper can be given air permeability by adjusting the amount of wax applied, and it can prevent water mushrooms due to the moisture properties of the paper material, and also prevent water wetting. Can be used repeatedly. In recent years, the cultivation of enoki mushrooms has become popular with white enoki mushroom cultivation. This white enoki mushroom is easier to dry than conventional enoki mushrooms, and if you use conventional wax paper, there will be problems such as poor side branch elongation and a wide open umbrella. . Therefore, a wrapping paper devised to solve such problems has been proposed.

  For example, the wrapping paper disclosed in Patent Document 2 below uses a fan-shaped polyethylene film made of a gas-permeable blocking material and fan-shaped wax papers respectively disposed on the front and back surfaces of the polyethylene film and laminated them. Thus, the structure is integrated and bonded together. This wrapping paper is manufactured by sandwiching a polyethylene film between two sheets of paper, thermocompression bonding, applying wax (wax) on both sides, and squeezing the wax to squeeze it. According to this wrapping paper, since the polyethylene film is sandwiched between them, the air permeability can be lowered as compared with the wrapping paper using the conventional wax paper. In addition, since wax paper is bonded to the front and back surfaces of the polyethylene film, it is said that it can be prevented from becoming a mushroom due to the hygroscopicity of the wax paper. Further, the wrapping paper disclosed in Patent Document 3 below uses a paper material having air permeability and moisture absorption as a core material, and applies a brazing material to both surfaces of the paper material, thereby preventing wetting and smoothing the surface. The paper material is subjected to a waterproofing treatment in order to obtain the performance and to suppress the air permeability of the paper material. This waterproofing treatment is performed by a method in which a synthetic resin is thinly coated on a paper material and then the surface is coated with a brazing material, or a paper material is coated with a brazing material containing a waterproofing material. This wrapping paper is supposed to obtain the same result as the wrapping paper of Patent Document 1.

Japanese Patent No. 3481606 (paragraphs [0015] to [0018], FIGS. 2 to 5) Japanese Patent Laid-Open No. 3-228622 (the second column, lower right column, FIG. 2) Japanese Patent Laid-Open No. 7-203762 (paragraphs [0010] to [0013], FIG. 1)

  Among the above wrapping papers, wax paper can give a certain degree of air permeability, can prevent water mushrooms due to the moisture of the paper material, and can be used repeatedly to prevent water wetting It has become. However, since the wax paper is obtained by applying wax (wax) to a paper material, it is worn out repeatedly and has a problem in durability. In order to solve this problem, a wrapping paper in which a polyethylene film is sandwiched between paper materials is proposed in Patent Document 2 described above. However, this wrapping paper requires a special manufacturing technique and a dedicated device, and is easily manufactured. There is a potential problem of being unable to do so. Therefore, the wrapping paper of Patent Document 3 is an improvement over that of Patent Document 2. However, since the wrapping paper of Patent Document 3 is also obtained by processing a paper material, the problems of wear and durability are not solved. Moreover, in the cultivation field of enoki mushrooms, a wound fabric using a non-woven fabric, for example, “Tyvek 1082D” (registered trademark) manufactured by Asahi DuPont Flash Spun Products Co., Ltd. is used. This wrapping cloth is superior in durability to wrapping paper such as the above-mentioned wax paper, but has room for improvement due to air permeability. Therefore, such wrapping paper and wrapping cloth cannot be cultivated with high quality and high yield unless the air permeability is suitable for cultivation of enoki mushrooms. On the other hand, in recent years, due to diversification of distribution channels for sales, supermarkets and other stores are demanding better quality and high quality enoki mushrooms, but this demand cannot be met.

  In addition, the wrapping paper is used by being detachably attached to the bottle opening. However, the attachment using a hook-and-loop fastener such as the wrapping paper of Patent Document 1 uses a stopper such as a conventional rubber band or clip. Compared with conventional wrapping paper, it is not necessary to manage the stopper and the attachment / detachment work is simplified. However, the wrapping paper of Patent Document 1 requires a punching operation for forming a through hole in the wrapping paper (base material) and a fixing operation for an adhesive support sheet body provided with a surface fastener member in the through hole. The work is extremely troublesome and causes high costs. In addition, although the thing using a hook-and-loop fastener is commercialized, the fixation of the hook-and-loop fastener to the cloth of a base material becomes an adhesive agent or thread sewing to the base cloth. In this type of wrapping fabric, the hook-and-loop fastener can be easily detached from the base fabric when the adhesive strength of the adhesive is reduced. Yes.

  Therefore, the inventors verified the conventional wrapping paper, etc., and if the air permeability of the wrapping paper is too low, the yield is increased, but it tends to become a mushroom, and the shelf life is deteriorated. If it is too high, it will be difficult to become a mushroom, the thickness of the stem will become thick and the shelf life will improve, but the yield will decrease, and instead of the paper wrapper, use a non-woven fabric roll If the air permeability of the roll cloth is set within a predetermined range, the yield and quality are balanced, and it is found that the yield of A product can be increased, and further, high quality and long-lasting enoki mushrooms can be cultivated, As for the attachment to the bottle mouth, a hook-and-loop fastener is used, and the hook-and-loop fastener can be fixed to the base material without using any conventional adhesive or thread stitching, thereby completing the present invention. With That. In addition, A goods point out what is not inferior goods, and has become the quality display normally used in the cultivation industry.

  The present invention has been made on the basis of the above-mentioned findings while solving the above-mentioned problems of the prior art, and an object of the present invention is to adhere to a nonwoven fabric composed of fibers containing a thermoplastic resin with an adhesive or thread stitching. Another object is to provide a winding fabric for straw cultivation in which a hook-and-loop fastener is fixed by heat fusion.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the embodiment shown below exemplifies the winding fabric for straw cultivation for embodying the technical idea of the present invention, and is not intended to limit the present invention to the following embodiment. The present invention can be equally applied to various modifications without departing from the technical idea shown in the claims.

  First, a general cultivation method for enoki mushroom will be described with reference to FIG. In addition, FIG. 4 is process drawing of the cultivation method of an enoki mushroom. In addition, this method is a cultivation method using the winding cloth for straw cultivation of the Example of this invention.

  As shown in FIG. 4, the cultivation of enoki mushrooms is performed by first mixing an additive such as rice bran or flour beet into a base material such as sawdust or corn cob at a predetermined ratio, and adding a predetermined amount of water to water. The rate is adjusted to a predetermined value, and the prepared medium is packed into a bottle container of a predetermined size (S1, S2). In the culture medium packed in the bottle container, one or a plurality of inoculation holes having a depth reaching from the upper surface to the bottom of the culture medium are formed (S3). This inoculation hole is formed in order to allow the inoculum to fall to the bottom of the medium, to allow the mycelia to smoothly grow throughout the medium, and to improve the flow of air in the medium.

  The bottle container in which the inoculation hole is formed is conveyed to the sterilization chamber to sterilize the culture medium, and the sterilized culture medium is inoculated with the inoculum of enoki mushrooms and conveyed to the culture chamber of a predetermined atmosphere and cultured (S4 to S6).

  In the next fungus mushroom (S7), in order to generate enoki mushrooms from the mycelia in the vigorous medium, an operation of removing the hyphae of the aged fungus species is performed.

  After the fungus has been sown, sprouting management (also referred to as the generation operation) is performed in a predetermined atmosphere (S8), and then, the buds are grown and the growth of the stems is suppressed while promoting the enlargement of the umbrella parts. And smoothing (also referred to as the early growth period) (S9). This leveling and suppression is because the fruiting body (mushroom) has a small umbrella and a soft stem, is not susceptible to low temperature and drying, and has a relatively high ambient temperature (14-15 ° C) in the previous process. And then suddenly encountering a low temperature (4-5 ° C.) in this suppression step, the fruit body umbrella dries out and no longer grows. 7-8 [deg.] C.) and then the temperature is lowered (3-4 [deg.] C.) to suppress stem growth. Then, the temperature is maintained at 5 to 7 ° C. through a wrapping paper (wrapping cloth) (S10), and late growth management (S11) is performed. In addition, for example, there is a trade name “Tyvek 1082D” (registered trademark) manufactured by Asahi DuPont Flash Spun Products Co., Ltd.

  Cigarette (wrapping cloth) is a unique process of enoki mushroom cultivation. By covering the periphery of enoki mushroom with a paper roll, the concentration of carbon dioxide is increased, the growth of the umbrella is suppressed, and the growth of the stem is promoted. Done for. This cigarette has a longer stem than wild enoki mushrooms, increases yield, and is easy to handle in terms of distribution and sales. On the other hand, for the growth of enoki mushrooms, the environment becomes worse, and malformations of enoki mushrooms and water mushrooms are more likely to occur. Therefore, papers with different air permeability have been proposed, but if you do not use a paper roll (wrapping cloth) that matches the growth environment of the enoki mushroom, it must be of high quality and The yield cannot be increased, and a product with good shelf life cannot be obtained. That is, if the air permeability is too bad, it tends to become a mushroom, and the yield increases, but the shelf life becomes bad. On the other hand, if the air permeability is too good, the increase in carbon dioxide concentration becomes insufficient and the yield decreases.

  Therefore, the winding fabric for straw cultivation according to Example 1 of the present invention (hereinafter sometimes simply referred to as a winding fabric) has an air permeability of 1.9 to 11.0 instead of the conventional wrapping paper and the winding fabric. It is comprised with the nonwoven fabric selected in the range of the second (JIS L1096: 1999 8.27 B method). With this wound cloth, the yield and quality are balanced, and the yield of the A product can be further increased, and the higher quality and long-lasting enoki mushroom can be cultivated. In the cultivation of enoki mushrooms, indoor air control is performed, but in combination with this air control, the air permeability is small as measured using the Gurley tester in accordance with the above-mentioned JIS L1096: 1999 8.27 method B That is, the above-mentioned cultivation effect can be achieved by using a non-woven fabric with good air permeability as a wound fabric. In addition, it is preferable that the wound fabric has a wear strength of class A (JISL1096: 1999 8.17 Method C, determination of appearance change). Since the wear strength is Class A, that is, the surface has a high degree of smoothness and is slippery, the stems are difficult to stick to the winding cloth during the cultivation of enoki mushrooms, and the growth of the stems is not inhibited. In addition, since it is highly durable, it can be used repeatedly. Furthermore, since it is hard to get dirt, it becomes hygienic.

  In the following, the shape of the sown cultivation fabric and the method for producing the nonwoven fabric that will be the fabric of this sushi cultivation fabric will be described. As shown in FIG. 1, this wrapping roll for straw cultivation 1 has a sector shape having arc-shaped upper and lower sides 1 a and 1 b and substantially straight left and right sides 1 c and 1 d, and part of the left and right sides 1 c and 1 d. It has the structure which provided the attachment means which can be attached or detached freely. This attachment means is composed of hook-and-loop fasteners 2a and 2b. This surface fastener will be described later.

  Although this wrapping fabric 1 for silkworm cultivation processes and produces a nonwoven fabric, an example of the manufacturing method of this nonwoven fabric is shown below. This nonwoven fabric is manufactured by using an original fabric made of a directly-spun type nonwoven fabric. In other words, this non-spun type non-woven fabric is a method in which a thermoplastic polymer material is melted and discharged into a continuous long fiber, and is generally called a spunbond method. In the production of the nonwoven fabric by the spunbond method, raw material polypropylene pellets are supplied to an extruder, and the pellets are heated and melted, and sent to the next spinning / drawing step. In this spinning and drawing process, the melted raw material is extruded from a plurality of (for example, 10,000 nozzles (one nozzle diameter is 1 mm or less, for example)), and simultaneously with this extrusion, it is pulled by an ejector and cooled between them. By thinning the melted raw material, a thin thread having a diameter of 20 μm or less is formed. Next, the yarn discharged from the ejector is dropped onto a net-like conveyor called a collector and conveyed to the next fusion process. In addition, the state of the thread that has fallen on the collector is called a web and is a cotton-like fiber. Next, heat is applied to the web with a heat roll to fuse the fibers. The heat roll is usually embossed, and a soft sheet such as a cloth is formed by spot fusion of the fibers. The sheet is wound with a winder to complete the nonwoven fabric. Then, the air permeability and abrasion strength are adjusted by passing a heat roll of a predetermined temperature through the nonwoven fabric, and the sheet material is completed.

  Next, the example of the method of processing the said sheet material and producing the winding fabric 1 for straw cultivation is demonstrated. A plurality of substantially fan-shaped winding cloths are cut from a sheet material adjusted for air permeability and the like, and a winding cloth for straw cultivation 1 is created. As shown in FIG. 3, when the wrapping cloth for straw cultivation 1 is wound around the bottle mouth of the cultivation bottle 3, the upper edge and the lower edge are slightly arcuate so that the upper part becomes a slightly open cylindrical shape. At the same time, both ends overlap to form a length that covers the entire circumference of the bottle mouth. That is, as shown in FIG. 1, the wound fabric 1 is formed into a piece of cloth having arcuate upper and lower sides 1a and 1b and substantially straight left and right sides 1c and 1d. The winding cloth 1 is also provided with detachable attachment means on part of the left and right sides 1c and 1d.

  For the attachment means, hook-and-loop fasteners 2a and 2b are used. A common hook-and-loop fastener, for example, a commercially available one, has a female surface in which a large number of loop-shaped female engaging elements are implanted on one side, and a shape that is entangled with the female coupling element, such as a hook shape or a mushroom shape. And a pair of fastener members having a male surface on which a plurality of male engaging elements are implanted, and a pair of fastener members provided with these engaging elements are coupled. Since the surface fastener requires predetermined elasticity and rigidity for the female and male coupling elements, respectively, a resin material having a high melting point, such as nylon or polyester, is used as the material. Such a hook-and-loop fastener is used by being fixed to a sheet material such as cloth. The fixing differs depending on the sheet material, and is usually fixed by heat fusion, thread stitching, an adhesive, or the like.

  Since such hook-and-loop fasteners are widely used in various applications such as clothing and bags, the inventors tried to heat-seal the wound fabric 1 using the hook-and-loop fasteners. However, it has been found that this hook-and-loop fastener is heat-sealed to the webbing 1, but is easily removed when a slight force is applied without sufficient heat-sealing. It was found that the cause is that the melting points of the materials constituting the surface fastener and the wound fabric are different. That is, a commercially available hook-and-loop fastener is formed of a high melting point resin material as described above, while the nonwoven fabric of the wound fabric 1 is made of polypropylene, which is a low melting point thermoplastic resin material, Since the melting points of these materials are different, heat fusion cannot be made sufficient. For this reason, until now, such a surface fastener has not been fused to a sheet substrate made of a thermoplastic resin. Needless to say, such a surface fastener that has been heat-sealed to a wrapping paper or a webbing fabric has not been put into practical use, and a method using an adhesive or thread stitching or a fixing method disclosed in Patent Document 1 is employed.

  Therefore, in Example 1 of the present invention, a hook-and-loop fastener is manufactured using the same type of material as that of the webbing 1, and the hook-and-loop fastener is heat-sealed. By forming the hook-and-loop fastener with the same type (same quality) material as that of the wound fabric 1, the melting points of both are the same and can be firmly fixed. This hook-and-loop fastener may have a slight decrease in performance, particularly elasticity and rigidity, compared to conventional hook-and-loop fasteners. However, this decrease is due to the size of the hook-and-loop fastener or the shape of the female and male coupling elements. For example, in the case of a female engagement element, the size and density of the loop shape are changed, and in the case of a male engagement element, the female engagement element is entangled with the change of the female engagement element. Thus, it can be compensated by changing the size and density of the hook shape and mushroom shape, and even if used for bottle cultivation of enoki mushroom, there is no problem.

Therefore, in Example 1 of the present invention, a pair of hook-and-loop fasteners having female and male coupling elements is manufactured using the same type of material as the material of the wound fabric 1, that is, a polyolefin resin material containing polypropylene. This production is carried out by the same manufacturing method as that using a conventional resin material (nylon, polyester, etc.) as a raw material. In addition, since this manufacturing method is well-known, description is abbreviate | omitted. The produced surface fasteners 2a and 2b have female and male coupling elements 2a ₁ and 2b ₁ as shown in FIGS. 1 (a) and 1 (b). A pair of hook-and-loop fasteners 2a and 2b having female and male coupling elements 2a ₁ and 2b ₁ made of a polyolefin-based resin material are cut into predetermined sizes (for example, a quadrilateral having a side of about 1.5 cm). Then, the respective hook-and-loop fasteners 2a and 2b are fixed to the vicinity of the left and right sides 1c and 1d of the winding cloth 1 by heat fusion. When these hook-and-loop fasteners 2a and 2b are used, the hook-and-loop fasteners 2a and 2b and the wrapping cloth 1 have the same quality, so the melting points are the same and they are firmly fixed by heat fusion.

  In addition, as in the prior art, troublesome work such as a method using an adhesive or thread sewing or a fixing method disclosed in Patent Document 1 is not necessary. Winding cloth 1 is used by wrapping around the bottle mouth. At that time, if the area of the pair of hook-and-loop fasteners is small, the coupling region is narrow and the amount of winding cannot be adjusted. It is preferable to enlarge either one of the surface fasteners 2a ′ and 2b ′. As a result, the winding cloth 1 'can be attached by adjusting when the binding area is widened and wound around the bottle mouth.

  In Example 1, the hook-and-loop fastener is made of the same material as the material of the webbing 1, but may be heat-sealed by other methods. For example, a conventional surface fastener can be used by lining a thermoplastic resin film of the same type as the webbing 1. Moreover, even if it is a winding cloth of a prior art, heat fusion | fusion becomes possible by producing a hook-and-loop fastener with the same kind (same quality) as this winding cloth.

  The winding fabric for straw cultivation according to Example 2 adjusts the wear strength of a non-woven fabric used as a sheet material to Class B (JISL1096: 1999 8.17 Method C, change in appearance) and has air permeability of 0.2 or more. It is created in the same manner as in Example 1 except that it is selected from the range of less than 1.9 seconds and 11.0 seconds or more and less than 16.0 seconds (JIS L1096: 1999 8.27 B method).

The wound fabric for straw cultivation according to Example 3 does not perform temperature control on the nonwoven fabric raw material, that is, the raw material is used instead of the sheet material, and the air permeability is 0.46 to 116 cm ³ / cm ² · s. It creates like Example 1 except selecting from the range of (JIS L1096: 1999 8.27.2 A method).

[Comparative Examples 1 and 2]
The wrapping paper of Comparative Examples 1 and 2 is a known one, and the wrapping cloth of Comparative Example 1 is formed of a nonwoven fabric. The air permeability measured by the manufacturer using a Gurley tester is a target value ( 99.7% of the product is expected to fall within this range) as 17 to 45 seconds. Comparative Example 2 is a wound sheet in which a plurality of small holes are provided in a resin film, and the air permeability of this wound sheet cannot be measured structurally. In the measurement of air permeability, a material with good air permeability whose measured value by the JIS L1096: 1999 8.27 B method is 0.2 seconds or less is a fact in the JIS L1096: 1999 8.27 B method. Since it cannot be measured above, it is measured by the JIS L1096: 1999 8.27 A method instead.

  Using the wrapping papers of Examples 1 to 3 and Comparative Examples 1 and 2, tests were performed on yield, number of stems, defective product rate, and discoloration, and the results shown in Tables 1 to 4 were obtained. The test method is to prepare 10 containers for 16 cultivation bottles (ie, 160 cultivation bottles), and obtain data such as yield, number of stems, defective product rate and discoloration for each container. Each sample was taken and the average value of 10 containers was calculated.

この表１から、収量の平均値は、比較例２が２７１．２ｇで一番多く、続いて、比較例１の２６５．７ｇ、実施例１の２６２．０ｇ、実施例２の２５３．８ｇ、実施例３の２５３．０ｇと続いている。そして、実施例１〜３は、比較例２に対して３〜１０％少なくなっている。 Table 1 shows the yield.

From Table 1, the average value of the yield was the highest at 271.2 g in Comparative Example 2, followed by 265.7 g in Comparative Example 1, 262.0 g in Example 1, 253.8 g in Example 2, This is followed by 253.0 g of Example 3. And Examples 1-3 are 3-10% less with respect to the comparative example 2. FIG.

この表２から、茎数の平均値は、比較例２が８１１本と一番多くなっていたが、小さい芽が多く目立ち、足も細くなったものが多かった。これに対して、実施例１は６９３本、実施例２は６９０本、実施例３は６７７本で、比較例２の８１１本に対して最大で約１７％程度少なくなっていたが、小さい芽が少なく、５ｃｍ以下のものも少なく、しかも足が太いものが多かった。比較例１は７５０本で本数がそれらの中間にあったが、細いものが目立っていた。 Table 2 shows the number of stems.

From Table 2, the average value of the number of stems was 811 in Comparative Example 2, which was the largest, but many small buds were conspicuous and the legs were thin. On the other hand, Example 1 had 693, Example 2 690, and Example 3 677, which was about 17% less than 811 of Comparative Example 2, but small buds. There were few, and there were few things below 5cm, and many legs were thick. The comparative example 1 was 750 and the number was in the middle, but the thin one was conspicuous.

この表３から、この不良品率の平均値は、比較例２は１１．６％、比較例１は５．５％であったのに対して、実施例１は２．１％、実施例２は、３．５％、実施例３は２．７％であり、各実施例が比較例に対して不良品の発生を抑制していることが分かる、比較例１に対しては、２割〜３割程度に、比較例２に対しては４割〜６割程度に低減している。特に、比較例２は、見た目に水っぽさがあり、全体的に小さいものとなっていた。 Table 3 shows the defective product rate, and a product that meets at least one of the following five criteria is defined as a defective product. The defective product rate means the ratio of the number of defective bottles to the 16 bottles (percentage is rounded off to the first decimal place). For example, if one bottle is defective, the container The yield rate is 7. The criteria for judging defective products are: 1. The total length of the enoki mushroom is shorter than 13 cm or longer than 15 cm. 2. The thin stem is noticeable. 3. Umbrella (stalk head) has illness, etc. 4. It is a mushroom. The stems are not growing on average.

From Table 3, the average value of the defective product ratio was 11.6% in Comparative Example 2 and 5.5% in Comparative Example 1, whereas 2.1% in Example 1 and Example 2 is 3.5%, and Example 3 is 2.7%. It can be seen that each example suppresses the generation of defective products compared to the comparative example. It is reduced to about 40% to 60% for Comparative Example 2 to about 30% to about 30%. In particular, Comparative Example 2 had a watery appearance and was small overall.

この表４で、数字が大きい方が変色が激しくすなわち日持ちが悪いことを示している。変色度の平均値は３日間および６日間のいずれにおいても、各実施例１〜３の値が比較例１、２を下回り、比較例１、２に対して日持ちが良いことが分かる。特に変色度３日間の平均値は、比較例１は２７、比較例２は４０であるのに対して、実施例１、２はともに１９、実施例３は１６となり、各実施例１〜３は比較例２に対しては半分以下、比較例１に対しては３分２程度になっている。 Table 4 shows the shelf life. In this shelf life test, 10 strains were randomly taken out from each bottle, and left at room temperature (about 8 ° C. to 26 ° C.) for 3 days and 6 days in a packaged state to determine the degree of discoloration. The degree of discoloration was represented by a four-stage score of 10, 25, 50, and 75. “10” when the appearance is hardly discolored, “25” when the whole begins to change color but does not change color darkly, “50” when it is in a state that cannot be eaten due to considerable discoloration, and darker overall The case where the color is changed and partly rotten is set to “75”.

In Table 4, a larger number indicates that the color change is more severe, that is, the shelf life is poor. It can be seen that the average value of the degree of discoloration is lower than those of Comparative Examples 1 and 2 in both Examples 1 to 3, and the shelf life is longer than that of Comparative Examples 1 and 2. In particular, the average value of the color change for 3 days was 27 for Comparative Example 1 and 40 for Comparative Example 2, whereas 19 for Example 1 and 2 was 16, and 16 for Example 3. Is less than half for Comparative Example 2 and about 2/3 for Comparative Example 1.

  As described above, according to the enoki mushroom cultivation using the roll cloth according to each example, it is possible to cultivate the high quality and long-lasting enoki mushrooms as compared with the conventional wrapping paper and the roll cloth. Further, since the surface of the wound fabric is made of the same material as that of the wound fabric, it can be fixed by heat fusion, and the fixing becomes simple and firm, and does not come off during use.
