Description

The present invention relates to a natural straw cultivation apparatus, and in particular, a method for producing a natural straw that has a high degree of freedom in selecting an installation location of the cultivation equipment, can greatly reduce labor required for planting and harvesting, and can be easily harvested without requiring a natural straw extraction device. It is about.

 Conventionally, it is described in Patent Document 1 as having less labor at the time of planting and harvesting than a cultivation method in which natural culm is cultivated in a pipe buried in a mainstream cultivation field, and can significantly increase the yield per unit area. "Natural pod cultivation method and cultivation apparatus" has been proposed. This is because the lower end is buried in cultivated soil, and the soil is filled up to the substantially upper end in a pipe that is vertically held and arranged in one or more rows. At the time of harvesting, the pipe is removed from the cultivated soil and set in a special natural dredging device, and one end of the pipe is pressed by water injection and air pressure to take out the natural dred that has been grown as soil for use from the pipe.

JP 2009-296927 A

 However, in the above cultivation method, seeds of natural pods are planted at the substantially upper end of the soil filled in the pipe and grown while appropriately fertilizing and pouring water, so that the new pods are contaminated with fertilizers or agricultural chemicals. There is a concern that the normal growth of new pupae may be hindered by these effects.

 In addition, when harvesting, it is necessary to extract a heavy pipe filled with soil and new culm from the cultivated soil, and to transport and attach the extracted pipe to the place where the natural dredging device is installed. It will take a lot of time and effort. Moreover, this special natural picking device leads to an increase in the cost of natural picking as a product. Also, pipes need to be installed in a state where the lower end is buried in the cultivated soil and held vertically, so cultivated soil for that purpose is necessary, and can be installed directly on a concrete surface such as the roof of a building There is also a problem that the degree of freedom in selecting the installation location is low.

To solve the above problem,
The method for producing natural dredging according to claim 1 includes: a container having an open top and an opening in a bottom wall; and one end of a pipe being opened and the other end being closed, and the open end of the pipe being defined as the opening. In a method for producing natural pods, preparing a new culm breeding body inserted upwards, planting seed pods in the container, and cultivating and harvesting new culm in the new culm breeding body,
The pipe for growing the new cocoon is filled with the soil for growing the new cocoon and wetted with water. The soil area connected to the soil to grow the germination point of the seed pod is provided in the container, and the water is poured and moistened. A cultivated soil region where the main absorption roots of seed pods grow is provided adjacent to the soil region, and the soil region has a larger area than the upper surface of the soil region and allows the contaminated water to penetrate into the soil region. Cover with a water-impermeable sheet to prevent, arrange germination points of the seed pods on the water-impermeable sheet substantially at the center of the upper surface of the soil area, and disperse the main absorption roots in the cultivated soil area Then, fertilization and water injection are performed on the cultivated soil region outside the water-impermeable sheet.

The method for producing natural cocoons according to claim 2 is the method for producing natural cocoons according to claim 1,
The new pupa growing body is formed with a slit over the entire length in the longitudinal direction of the pipe, and is closed with one end of the pipe being opened and the other end being suppressed on the outer periphery of the end, Covering the slit and having a covering member that prevents the soil from flowing out, measuring the spread of the slit width accompanying the enlargement of the new cocoon, and estimating the degree of enlargement of the new cocoon and taking necessary enlargement measures It is a thing.

According to the natural dredging production method of claim 1, a soil area connected to the soil of the new straw growing body and a cultivated soil area adjacent to the soil area are provided in the container, and the soil area is placed on the soil area. Cover with a water-impermeable sheet that has a larger area than the top surface and prevents contaminated water from penetrating into the soil area, so that the germination points of seed pods grow in the soil area, and the main absorption roots grow in the soil area. As a result, fertilization and water injection were applied to the cultivated soil area outside the water-impermeable sheet, so contaminated water mixed with water injection, rainwater, fertilizers, fungicides, insecticides, etc. descended the cultivated soil area to the container. It is discharged outside and penetration into the soil area is prevented. For this reason, it is prevented that the disease germs that move with the contaminated water enter the soil region, and the germination point of the seed pod grows healthy without being violated by the disease fungus in the soil region and extends downward to It is possible to grow and harvest natural straw without disease in the soil.

According to the natural cocoon production method of claim 2, in the natural cocoon production method according to claim 1, the new cocoon breeding body is inserted into the container opening of the pipe with a slit formed over the entire length in the longitudinal direction of the pipe. The side that is released and the other side is closed with the outer periphery of the end being suppressed, the spring pressure effect of the pipe plate is strengthened, and a new cover is provided that has a covering member that covers the slit in the pipe and prevents the soil from flowing out As we tried to enlarge the soil so that sufficient earth pressure was applied, we measured the widening of the slit width associated with the enlargement of the new cocoon, estimated the extent of the new cocoon enlargement, and applied the necessary enlargement measures. Can surely harvest the enlarged natural cocoons. For this reason, the work which confirms the quality of the natural selection by trial digging before the harvest like the conventional one is unnecessary.

Hereinafter, embodiments will be described with reference to FIGS . 1 to 11 .

In FIG. 1, the natural pod cultivation apparatus 1 is mainly composed of a gantry 2, a container 25 for planting seed pods 45 (see FIG. 2) to grow main absorption roots 47 (see FIG. 2), and new pods 46 (FIG. 2). And a new pupae growing body 15 that grows and enlarges them, and these are combined together and installed on a base 62 whose height is adjusted to the ground 63. The gantry 2 is integrally formed by a support 3, an upper connecting body 4, a middle connecting body 5, a lower connecting body 6, a holding bar 7 and a support bar 8. Two holding bars 7 are attached on both short sides of the middle connector 5, and two support bars 8 are attached on both short sides of the lower connector 6.
In addition, although the mount 2 of the present Example 1 showed what was formed with the timber, not only this but the structure comprised combining iron pipes etc. may be sufficient.

In the container 25, a side wall 26 and a bottom wall 27 are integrally formed and an upper portion is opened. Each of the side walls 26 is formed in a box shape by integrating two long sides and short sides, and the bottom wall 27 has a plurality of openings 28 into which the pipes 16 of the new pupae growing body 15 are inserted with a central interval of 250 to 250. Two rows are provided in the long side direction at 300 mm, and a plurality of drain holes 29 (see FIG. 2) are opened. The diameter of the opening portion 28 was formed to be 4 mm larger than the outer diameter of the pipe 16 so that the new cocoon growing body 15 could be easily extracted from the opening portion 28 when harvesting natural pods. Two net struts 55 are respectively attached to both short sides of the side wall 26 of the container 25 with a fixture 56, and a cucumber net 57 is interposed between the net struts 55 along the long side of the side wall 26. It is stretched and attached.
In addition, although the container 25 of the present Example 1 showed what was formed with the timber, not only this but the thing formed with the hard plastic material with low heat conductivity may be sufficient.

In FIG. 2, the internal configuration of the new pupa growing body 15 and the container 25 and the relationship with each other are shown in detail.
The new pupa growth body 15 is configured by combining a pipe 16, a cap 18, and a cover member 20, and a slit 17 (see FIG. 1) is formed in the pipe 16 over the entire length. As the pipe 16, a gutter made of vinyl chloride having a name 75 (outer diameter 74 mm, inner diameter 71.8 mm, thickness 1.1 mm) and a length of 1200 mm was used. The cap 18 uses a plastic flower pot, and the end of the pipe 16 is inserted in a state in which the inner periphery of the open end of the cap 18 is fitted to the outer periphery of the lower end of the pipe 16 with the slit 17 of the pipe 16 closed and the outer periphery is suppressed. They are closed and fixed with a cloth-containing adhesive tape (not shown).

The covering member 20 prevents the soil 41 from flowing out when the slit 17 is pushed and expanded with the enlargement of the new tub 46, and is formed of a transparent sheet made of vinyl chloride having a thickness of 0.25 mm. The slit 17 is blocked by receiving the earth pressure of the soil 41 filled in the pipe 16 and pressing it against the inner wall of the pipe 16. In addition, although the covering member 20 is not necessarily limited to a transparent sheet, it is preferable to use a transparent sheet because the wetness of the soil 41 when the width of the slit 17 widens can be seen from the outside. As the soil 41, fine red and sterile red soil suitable for growing the new cocoon 46 was used.
First, a gourite 40 is laid on the bottom of the cap 18 to improve drainage, and then the soil 41 is filled and poured to wet the soil 41. Excess water is discharged from the drain hole 19.

The new pupa breeding body 15 is inserted into the opening 28 of the container 25 with an average gap of 2 mm from the open end of the pipe 16 and protrudes from the bottom surface of the container 25 to a predetermined length so that the slit 17 of the pipe 16 can be easily formed. The bottom surface of the cap 18 is placed on the support bar 8 toward the long side (passage side) of the gantry 2 so that it can be observed, and is held by the binding band 60 so that the position of the pipe 16 does not shift laterally when receiving external force. Fastened to bar 7.
Here, the bottom surface of the cap 18 is protruded from the end of the support bar 8 in order to make it easy to take out the new culm growing body 15 at the time of harvesting, and the drainage hole 19 is opened to the protruding part and closed by the support bar 8. I try not to peel it off. As described above, the pipe 16 is opened so that it is not blocked by the support bar 8. As described above, one open end of the pipe 16 is inserted into the opening 28 of the container 25 with a certain narrow gap, and the other end is closed in a state where the outer periphery is suppressed by the cap 18, so that both ends are closed. Since the outer periphery is suppressed, the spring pressure effect by the pipe plate around the slit 17 is sufficiently strengthened. It should be noted that when sunlight directly hits the new cocoon growing body 15, the temperature of the pipe 16 reaches about 50 ° C., which is not preferable for the healthy growth of the new cocoon 46. The irradiation of sunlight on the body 15 is blocked.

  A goro stone 35 is laid on the bottom of the container 25 to improve drainage. A second water-impermeable sheet 37 made of a polyethylene sheet having a thickness of 0.2 to 0.3 mm is provided on the upper end portion (open end portion) of the pipe 16 so as to cover the portion. The lower end portion of the mesh cylinder 38 formed by rounding a cylindrical sheet of polypropylene having a thickness of about 1 mm with a large number of holes of about 2.5 mm square and fastening the seam with a stapler is the second water-impermeable. A soil region 42 that is attached to the upper end portion of the pipe 16 with the adhesive sheet 37 interposed therebetween and is connected to the soil 41 by filling aseptic mountain soil or red soil with fine particles is formed inside the mesh tube 38. When the mountain soil or red soil is stuffed into the net tube 38, the soil region 42 is moistened by water injection. Around the net tube 38, adjacent to the soil region 42, cultivated soil excellent in air permeability, drainage, water retention, fertilizer retention, etc. suitable for the growth of the main absorption root 47 and the auxiliary absorption root 48 of the seed potato 45 The cultivation soil area | region 43 which consists of is provided. The cultivated soil was prepared by appropriately blending Bora soil, Akadama soil, vermiculite, mountain soil, humus soil, and the like.

As described above, since the open end portion of the pipe 16 is covered with the second water-impermeable sheet 37, the open end portion of the pipe 16 of the new culm breeding body 15 includes the pipe 16, the covering member 20, and the covering member 20. Covered with the second water-impermeable sheet 37, the soil 41 in the vip 16 is isolated from the surroundings. For this reason, even if contaminated water mixed with bactericide and insecticide used for fertilizer / stems and leaves increases in the lower part of the cultivated soil region 43, these penetrate and penetrate the pipe 16 of the new culm breeding body 15. Entry from the open end is prevented, and nematodes and brown rot bacteria that move with them are prevented from entering the interior.
Even if there is a large amount of rainfall in the container 25, it is immediately discharged from the gap between the opening 28 and the pipe 16 and the plurality of drain holes 29, and rainwater accumulates at the bottom of the container 25, The cultivated soil region 43 is not excessively humid, and the open end of the pipe 16 is not soaked in water.

  The upper portion of the net tube 37 is covered with a first water-impermeable sheet 39 made of a polyethylene sheet having a thickness larger than the upper surface of the soil region 42 and having a thickness of 0.2 to 0.3 mm. Specifically, the first water-impermeable sheet 39 was a circular one having a diameter of 110 mm with respect to the outer diameter of the net cylinder 38 of about 78 mm. And the water injection hose 65 connected to the water supply apparatus which abbreviate | omitted illustration penetrates the 1st water impermeable sheet | seat 39, the earth area | region 42, and the 2nd water impermeable sheet | seat 37 to the earth 41 in the pipe 16. Water is injected as appropriate.

In order to cultivate natural cocoons in the natural cocoon cultivation apparatus configured as described above, first, from late March to early April, 50 to 100 g of cut seed buds are germinated by a known method, and the vine length is about 100 to 200 mm. Planted in a container around the end of May.
At the time of planting, first, a guide rod (not shown) from the top of the first water-impermeable sheet 39 is placed on the soil region 42 so as to protrude about 150 mm from the surface at a position that becomes the center of the net tube 38. The first water-impermeable sheet 39 is fixed by depositing 10-15 mm of new soil such as mountain soil, red soil, etc. on one water-impermeable sheet 39. The germination points of the seed potatoes 45 not shown are placed on the new soil along the guide rods, the main absorption roots 47 are dispersedly arranged in the cultivation soil region 43, and the seed potatoes 45 are covered with rice husks etc. The new soil was covered with about 50 mm so as not to touch the soil directly. On the main absorption root 47, about 10 to 15 mm of cultivated soil was piled up, and a fertilizer effect type fertilizer was applied once to save labor, and the cultivated soil was covered with about 50 mm and watered. Subsequent watering is carried out approximately once every three days, although depending on the weather, and the liquid fertilizer is applied almost once a week on the cultivation soil region 43 outside the first water-impermeable sheet 39. Water was poured into the water.
Before the rainy season was over and the sunshine was strong, we laid a paddle to control the ground temperature and prevent weeds from breeding.

  Thereafter, when the vines 49 were elongated and the leaves 50 increased, the vines 49 were attracted to the cucumber net 57 to reduce the overlapping of the leaves 50 and receive sunlight evenly. In addition, the main absorption root 47 also grows and extends in the cultivated soil region 43, and the germination point grows and penetrates through the first water-impermeable sheet 39, and extends downward in the soil region 42 to form the second water. The new pupa 46 grows in the pipe 16 through the impermeable sheet 37. However, although the neck part 46a about 200 mm below the germination point is an inedible part having an intermediate property between the stem and the cocoon, a large number of auxiliary absorption roots 48 are generated, and a large number of holes in the net tube 38 lead to the cultivation soil region 43. It stretches and absorbs moisture and fertilizer and contributes to the growth of the new pod 46.

 However, the neck 46a has a habit of bending due to obstacles, high temperature, excessive humidity, and the like, and the growth point of the cocoon is weak against fertilizers, soil diseases, and the like. In order for the new cocoon 46 to grow in the pipe 16, it is necessary for the neck 46 a to extend soundly without bending the soil region 42 and reach the open end of the pipe 16. Therefore, in the first embodiment, the soil region 42 is formed of aseptic fine soil or red soil with fine particles to remove obstacles such as stones, and the first water-impermeable sheet 39 is provided on the soil region 42. It is arranged to prevent penetration, over-humidity, and high temperature of contaminated water mixed with water injection, rain water, fertilizer, fungicide, insecticide, etc., and the neck 46a extends straight downward. . However, for a slight bend, the neck 46 a is guided by the net tube 38 and penetrates through the second water-impermeable sheet 37, and a new cocoon 46 grows in the pipe 16.

  As shown in FIG. 3 (a), the new culm breeding body 15 immediately after planting the seed pod does not yet contain the new culm 46, so the slit 17 of the pipe 16 is closed. As shown in FIG. 3B, the covering member 20 receives the earth pressure of the soil 41 and is pressed against the inner wall of the pipe 16 to close the slit 17. In addition, when filling the soil 41 into the pipe 16, the outer periphery of the pipe 16 was tied at four places with hemp strings not shown.

In the initial stage of planting the seed pod 45, it grows vegetatively by receiving the nutrition of the seed pod 45, but since the midsummer has passed and the temperature starts to drop, the new pod 46 enters the hypertrophication period due to reproductive growth that grows by receiving nutrition from the leaves and roots. . As shown in FIG. 4A, the width of the slit 17 is widened with the enlargement of the new heel 46 in the new heel breeding body 15 when the new heel 46 is enlarged. In this case, the cap 18 is fitted on the outer periphery of the lower end portion of the pipe 16 and the upper end portion is inserted into the opening portion 28 of the container 25 with a small gap, so that the spring pressure that suppresses the force for expanding the slit 17 is suppressed. The effect is greater than the spring pressure effect when the slit 17 is simply provided. For this reason, it is equivalent to the general cultivation system (the pressure applied to the new cocoon 46 is the spring pressure of the pipe + the earth pressure applied from the surrounding soil) in which the clever pipe provided with the slit 17 over the entire length is embedded in the soil. The earth pressure that enlarges the newborn cocoon 46 is obtained.

As described above, after the beginning of August, when the period of hypertrophy due to reproductive growth begins, it is important to observe the widening of the slit 17 and grasp the condition of enlargement of the newborn cocoon 46. When the enlargement is slow, it is necessary to take measures to promote the enlargement, such as necessary additional fertilization or water injection to the soil 41 in the pipe 16 by the water injection hose 65.
FIG. 5 shows the relationship between the outer diameter of the pipe 16; 74 mm (diameter), the diameter of a new cocoon at the time of harvesting; d (mm) and the width of the slit 17 of the new born growing organism 15; It is a graph of the example of measurement shown. As is clear from the figure, a slit width of about 25 mm or more is a standard for harvesting natural pods having a diameter of about 30 mm or more with good quality.

The harvest season begins when the leaves turn yellow or frost and stems and leaves end in late November.
In order to harvest natural cocoons, it is necessary to extract the new cocoon breeding body 15 from the opening 28 of the container 25 as shown in FIG. At this stage, the foliage is withered, and the neck 46a remains in the soil region 42 (see FIG. 2) from the upper end surface of the new cocoon breeding body 15.
The procedure for extracting the new pupae growing body 15 is to first remove the binding band 60 (see FIG. 2), and then remove the lower end portion of the new shoot growing body 15 from the support bar 8 that is placed laterally. Since the weight of the new pupae growth body 15 is about 7 kg, it can be easily lifted and moved laterally by hand to remove it from the support bar 8. Then, since the height dimension from the lower exit of the opening part 28 to the ground (63) is formed larger by the dimension H (mm) than the full length of the new heel breeding body 15, the new heel breeding body 15 has its own weight. It can be naturally dropped to the ground or can be easily pulled down to the ground by adding a small amount of manpower, and can be easily carried out of the gantry 2 by holding the extracted new culm breeding body 15 by hand.
As described above, according to the configuration of the first embodiment, it is possible to greatly reduce the labor burden on the operator when the new pupa growing body 15 is extracted from the container 25 and carried out to the outside.

 The newly-born cocoon growing body 15 carried out to the outside is first placed horizontally at the work place as shown in FIG. 7A, and the slit 17 is manually spread as shown in FIG. The convex portion 66 a is sandwiched and tied with the hemp string 67 together with the pipe 16. When the covering member 20 is pulled out in the longitudinal direction, the soil 41 appears between the widened slits 17. Next, as shown in FIG. 7 (c), when the newly born growth body 15 is shaken up and down with the slit 17 widened by turning the state of FIG. Since the soil 41a is discharged to the outside, the space in the pipe 16 is increased by that amount and the new tub 46 is exposed, so that it can be easily pulled out of the pipe 16 by hand. The time required to extract the new shoot breeding body 15 and harvest the new shoot 46 was able to be completed within about 3 minutes. The harvested natural pods generally had a length of 700 to 1200 mm and a weight of 300 to 600 g.

As described above, according to the harvesting method of the first embodiment, it is possible to easily harvest natural cocoons without requiring a special natural cocoon extraction device, and it is possible to remarkably reduce the labor burden of workers required for harvesting. Furthermore, if this harvesting operation is performed on a work table of an appropriate height, the labor burden on the operator can be further reduced because it can be performed without bending at all.
In addition, although the harvest number of the natural selection in this Example 1 depends on the size between the stocks, it can be expected that about 6000 to 7000 are obtained per 10 ares of the place where the cultivation apparatus is installed. This is an increase of 3 to 3.5 times compared to an average of about 2000 harvested trees by the standard clever pipe cultivation method.

FIG. 8 shows what forms the soil region 42 and the adjacent cultivated soil region 43 without using the net tube 38 in FIG. 2, and the parts not marked in FIG. 8 are the same as those in FIG. 2. The symbols are omitted.
The formation of the soil region 42 and the adjacent cultivated soil region 43 in Example 2 is performed as follows. That is, first, a cylindrical body 70 having a length equal to or greater than the height of the soil region 42 upward with the second water-impermeable sheet 37 provided so as to cover the upper end (open end) of the pipe 16 being sandwiched. In the cylinder 70, a soil area 42 connected to the soil 41 of the pipe 16 is provided, and a cultivation soil area 43 is provided outside the cylinder 70. Then, the cylinder 70 is removed and adjacent to each other. A land area 42 and a cultivated soil area 43 are formed.
The cylindrical body 70 is filled with aseptic mountain soil or red soil with fine particles to form a soil region 42 connected to the soil 41. When the soil or red soil is packed into the cylindrical body 70, water is injected. The soil area 42 is moistened. The implementation procedure after planting the seed pods after that is the same as in the case of Example 1.
When the number of natural cocoons planted reaches several tens to several hundreds, the net cylinders 38 are used to form the soil areas 42 and the cultivated soil areas 43 adjacent to each other. It is necessary, and the material cost and processing cost required for its formation are extremely high.
According to the second embodiment, the soil region 42 and the cultivated soil region 43 can be sequentially formed using a small number of cylinders 70 which are tools common to each container 25. It can be formed with very little effort and cost.

In FIG. 9, the new pupa growing body 15 is characterized in that a rigid pipe 16 having no slit 17 is used in the pipe 16, unlike the pipe 16 with the slit 17 in FIG. 2. is there. Therefore, the covering member 20 is not necessary, and the other parts in the figure are the same as those in FIG. That is, although the rigid pipe 16 having no slit is used, the new cocoon 46 is grown in the new cocoon growing body 15 as in the case of the first embodiment.
By the way, in order for the new cocoon 46 to enlarge, the earth 41 has a certain earth pressure and the cocoon tends to be thick. If there is no earth pressure, the new cocoon 46 has a habit of growing long and thin, but if the earth pressure greater than the force that the new cocoon 46 tries to thicken is applied, it will not grow thick. For this reason, the inner diameter of the rigid pipe 16 with respect to the diameter of the new tub 46 to be aimed at is inevitably determined. With regard to this point, if the maximum diameter of natural ridges that can produce cocoons with good quality is about 35 mm, the internal diameter of the rigid pipe 16 is empirically about 100 mm.
As described above, in the third embodiment, the inner diameter of the rigid pipe 16 is larger than that in the case of using the pipe 16 with the slit 17 of the first embodiment, and the amount of the soil 41 is increased. As in the case of Example 1, it is simple and the degree of freedom of installation of the cultivation apparatus 1 is high.

The point of extracting the new pupae growing body 15 in the third embodiment from the opening 28 of the container 25 is the same as that in the first embodiment.
Next, a procedure for taking out the new tub 46 from the rigid pipe 16 will be described with reference to FIG.
Harvesting of natural selection is performed using a harvesting tool 90. The harvesting tool 90 includes two base plates 91, an upper connection plate 92 and a side connection plate 93 that connect the base plates 91, and a tightening bolt 95. A step 91a having a predetermined depth is provided on the upper one side of the base plate 91, and the two base plates 91 are arranged in parallel with the side on which the step 91a is provided facing each other. On the upper surface, upper connection plates 92 are arranged on both sides of the pipe 16 to be inserted and attached with tightening bolts 95, side connection plates 93 are arranged on the side portions of the base plate 91 and attached with tightening bolts 95, and harvesting tool 90 is attached. Are assembled and installed on the base 97. A cushioning material 94 is arranged on the base 97 between the base plates 91 so that the fallen new soot 46 is received.

  In order to harvest natural cocoons, the cap 18 (see FIG. 2) is removed from the new cocoon breeding body 15, and the pipe 16 is raised and moved up and down in the direction of arrow B to fall on the step 91a of the base plate 91 facing the lower end surface. The soil 41 in the pipe 16 is discharged. When the discharged soil 41a increases and the inside of the pipe 16 becomes loose, the pipe 16 is placed sideways, and the new culm 46 is manually pulled out and harvested. When the new heel 46 falls, the tip of the heel is received by the cushioning material 94 to prevent damage.

As shown in FIG. 11, the natural pod cultivation apparatus 1 according to the fourth embodiment has individual containers 25 installed on the gantry 2. An individual container 25 in which the bottom wall 27 and the cylindrical side wall 26 are integrated is installed on the mount 2. The individual containers 25 are made of plastic resin, and are preferably made of a material having low thermal conductivity such as polystyrene, polypropylene, polyphenol, polyvinyl chloride resin, etc., in order to suppress the high temperature due to sunlight. The procedure from planting seed pods to harvesting natural pods is the same as in Example 1.
In the figure, each symbol is the same as or equivalent to that in FIG. The other parts are the same as those in FIG. 2, and the reference numerals are omitted.
By installing the individual container 25, even if a disease occurs in the new tub 46 of one container 25, it is possible to prevent the disease from being spread only by the new tub 46 of the container 25 and spreading to the whole. There is. Moreover, since the container 25 in this case can be used only by adding some processing using a cheap commercial item, the cost of the whole cultivation apparatus can be reduced.
