Description

  The present invention relates to a cultivation container.

  Conventionally, lotus root has been cultivated for a long time and is a highly demanded crop. In recent years, however, production has continued to decrease due to factors such as the aging of growers, the decrease in suitable land, and heavy labor for work.

  As a conventional method for growing lotus roots, the method of harvesting by hand using tools such as straw (Kuwabori) was common, but in recent years, digging with heavy machinery and using a water flow called a water moat have been used. As a harvesting method, a highly productive harvesting method has been established.

  However, such cultivation methods depend on the cultivation environment such as soil quality, the management scale of the cultivation farmer, and the like, and the cultivatable areas and growers are limited. In addition, such cultivation methods can harvest lotus roots in large quantities, but it is expensive capital investment, requires a certain level of management scale and labor, and as a result, small growers tend to decrease. is there.

  In view of this situation, the conventional lotus root cultivation method has been modified, a certain amount of soil is put in a box-shaped cultivation container of a certain size, seed lotus root is planted, and water maintains a certain height from the surface of the soil. In some cases, lotus root can be cultivated by managing in this way (see, for example, Patent Document 1).

  According to such a cultivation technique, lotus root cultivation that has been conventionally performed in limited places such as wet fields and ponds can be easily cultivated regardless of location, and small-scale cultivation and domestic cultivation are also possible. It becomes possible. In addition, by increasing the number of cultivation containers, etc., large-scale cultivation is possible, and an increase in the lotus root market supply can be expected.

It is a cross-sectional enlarged view which shows the modification of an operating rod. It is a figure explaining a mode that a lotus root is harvested.

  Hereinafter, the cultivation container which concerns on embodiment of this invention is demonstrated, referring FIGS. However, the scope of the invention is not limited to the illustrated examples. In addition, in the following description, what has the same function and structure attaches | subjects the same code | symbol, and abbreviate | omits the description.

  First, the cultivation container P which concerns on this embodiment is demonstrated, referring FIG. 1 (A) and the same figure (B). In the description of the present embodiment, front and rear, up and down, and left and right mean front and rear, up and down, and left and right with reference to a state in which the cultivation container P is viewed from the side surface to which the operation rod 6 is attached.

  As shown to FIG. 1 (A) and the same figure (B), the cultivation container P is comprised including the portable box-shaped container main body 1 by which the upper surface was open | released. The container body 1 can be made of an appropriate material such as resin or earthenware, but is preferably lightweight considering the ease of operation during harvesting. In this embodiment, the container body 1 is made of, for example, polypropylene. Yes. Further, the container body 1 has a bell-like shape in which the vertical and horizontal inner dimensions of the upper surface opening portion are slightly larger than the vertical and horizontal inner dimensions of the bottom surface, that is, the vertical and horizontal inner dimensions gradually expand from the bottom surface to the upper surface opening. . In this embodiment, the inner dimension (BW × BD) of the bottom surface of the container body 1 is 1125 mm × 690 mm, the dimension of the top opening (OW × OD) is 1210 mm × 778 mm, and the height inner dimension H is 445 mm, It has a capacity of 400L. The inner dimension of the bottom surface and the inner dimension of the upper surface opening portion may be the same, and each dimension is not limited to those described above, and can be set as appropriate. Here, the larger the size of the container body 1, the higher the yield can be expected. However, if it is too large, it will be difficult to turn the container body 1 over as described later, so it can be turned over manually by two adults. It is preferable that the size is approximately the same. In addition, the four corners of the container body 1 have an R shape.

  On the left side surface of the container body 1, a first drain port 2 a and a second drain port 2 b that are opened in a circular shape are provided above and below at a predetermined interval. That is, the second drainage port 2b is provided above the first drainage port 2a. The first drainage port 2a can be set to an appropriate height from the bottom surface, and considering a lotus root cultivation environment, a height of 15 to 25 cm is preferable from the bottom surface, and in this embodiment, about 250 mm from the bottom surface. The first drain port 2a is opened at a height. In addition, the second drainage port 2b is set with an appropriate dimension upward from the first drainage port 2a, and considering the cultivation environment of the lotus root, the second drainage port 2b is 5 higher than the height at which the first drainage port 2a was established. It is preferably a position that is higher by -15 cm and lower by 5-15 cm than the upper end of the container body 1. In this embodiment, the position is about 10 cm higher than the first drain port 2a. It is established at a height of about 350 mm from the bottom. On the other hand, the length from the 2nd drain 2b to the upper end of the container main body 1 is made into a little less than 10 cm. In addition, although the opening area of the 1st drain port 2a and the 2nd drain port 2b is made the same, you may differ. Further, in the present embodiment, the first drain port 2a and the second drain port 2b are opened at positions that are substantially coincident with each other in plan view, but may be opened at positions that are shifted in plan view. Moreover, the surface opened by the 1st drain port 2a and the 2nd drain port 2b may differ, for example, the 1st drain port 2a is opened in the left side surface of the container main body 1, and the 2nd drain port 2b is a container. You may make it open on the right side surface of the main body 1. Moreover, in this embodiment, it is set as the structure which provided the 2nd drainage port 2b in addition to the 1st drainage port 2a, By doing in this way, the quantity of water stored by the container main body 1 in the growing season of a lotus root is made constant. It is possible to maintain the soil, and it is easy to monitor the soil. Further, it is possible to suppress the dilution of the agricultural chemicals to be sprayed for the control of pests such as aphids. Moreover, when the lotus root volume increases due to the growth of the lotus root, the soil rises by that amount, and the height of the soil fluctuates. Therefore, by providing the second drainage port 2b, the amount of water can be adjusted accordingly. It becomes possible, and it becomes possible to reduce the labor of cultivation work. Further, by providing the drain ports 2a and 2b, when opening the plug, for example, even if flooding occurs and flooding occurs, water does not accumulate above the opened drain port, so that it is difficult to be washed away. However, the second drain port 2b may not be provided. Moreover, you may make it provide three or more drain outlets.

  The first drain port 2a and the second drain port 2b can be closed by drain plugs 4a and 4b, respectively. That is, in this embodiment, the drain plug 4a that closes the first drain port 2a functions as the first drain control unit, and the drain plug 4b that plugs the second drain port 2b functions as the second drain control unit. It is functioning. The drain plugs 4a and 4b are formed by integrally molding a cylindrical body portion and a head portion provided at the rear end thereof. The outer shape of the body portion is formed so as to substantially match the opening shape of the first drain port 2a or the second drain port 2b, and the outer shape of the head portion is more than the first drain port 2a and the second drain port 2b. Largely formed. Therefore, the drain plugs 4a and 4b can be inserted into and removed from the first drain port 2a and the second drain port 2b. In addition, the first drain port 2a and the second drain port 2b may be configured by, for example, drain pipes, and may be configured to control the discharge of water in the container body 1 by opening and closing valves.

  In addition, two memory lines (first memory line 5a and second memory line 5b) are provided on the inner peripheral side surface of the container body 1. The first memory line 5a provided below the two memory lines is at a height of about 250 mm from the bottom surface, and the second memory line 5b provided above is a height of about 350 mm from the bottom surface. It is in. The 1st memory line 5a is a line used as a standard which sets the soil height mentioned later, and the 2nd memory line 5b is a line for grasping | ascertaining the height of the soil raised for the growth hypertrophy of the lotus root. is there. That is, the area below the height at which the first memory line 5a is formed functions as a soil storage space. In the present embodiment, it is preferable that the height of the soil accommodated in the container body 1 is 250 mm or less. If the soil height is exceeded, the weight of the container body 1 becomes too large, and the lotus root is harvested. At this time, it is difficult to turn the container body 1 over. In this embodiment, the memory line may not be provided.

  Further, a flange portion 3 having a concave cross section is provided on the outer periphery of the upper end of the container body 1 so as to protrude outward, and a plurality of reinforcing ribs 3a are provided on the inner periphery of the concave flange portion 3. Are provided where appropriate.

  In addition, mounting holes 3b and 3b are provided on the upper surface of the flange portion 3 on the front side of the container body 1 to attach an operating rod 6 (see FIG. 3), which will be described later, at positions spaced a predetermined distance from the left and right ends. ing.

  Then, the cultivation point of a lotus root using the cultivation container P comprised as mentioned above is demonstrated, referring FIG.

  First, as shown to FIG. 2 (A), the soil which comprises the soil SO of the container main body 1 is produced | generated. For the production of the soil, first, after depositing a mixture of soil and compost from the bottom of the container body 1 to a height of about 20 to 25 cm, an appropriate amount of organic fertilizer and water are added thereto, Mix these. The amount of water to be added is, for example, such that the soil accumulated in the container body 1 is slightly higher than the water surface. At this time, the first drain port 2a and the second drain port 2b are both opened, and are adjusted so that excessive water is not stored in the container body 1.

  The seed lotus root SLR is planted in the soil SO thus generated. In this embodiment, the amount of seed lotus root SLR to be planted is, for example, 0.5 to 1.5 kg, and lotus root R having a weight of about 10 times can be harvested at the time of harvest. In FIG. 2, only one seed lotus root SLR is shown for easy understanding of the explanation, but actually, a plurality of seed lotus root SLRs are planted. In addition, as a planting time of the seed lotus root SLR, for example, around April is suitable, but it is not limited to this, and planting may be performed at an appropriate timing as long as the growth environment of the lotus root R allows.

  The cultivation container P in which the seed lotus root SLR has been planted in this way is placed outdoors, for example, and is not required to be transferred until the harvesting period. Thereafter, an appropriate amount of organic fertilizer is added about once a month while observing the growth state of the lotus root leaves. Moreover, you may administer a chemical fertilizer according to the growth time of the lotus root R.

  Thereafter, as shown in FIG. 2B, the lotus root R grows and the standing leaves SL are observed. In this embodiment, the standing leaf SL is observed from around May. At this time, the amount of water absorbed by the lotus root R increases. At this time, the first drain port 2a is closed with the drain plug 4a. Thereby, water WT can be stored in the range of the height of the opening position of the 2nd drainage port 2b from the surface of soil, ie, the water depth can be maintained now at about 10 cm. In this embodiment, the water depth can be maintained at such a high level, so that the state of the soil can be easily confirmed, and the pesticide to be administered when a pest such as aphid is generated is excessive in water amount. This reduces the possibility that the effect of dilution will be diminished. The water WT may be supplied as rainwater, but if it is insufficient, it is appropriately supplemented by irrigation. Here, the lotus root R has a plurality of growth points, and repeats extension and branching while forming nodes from the growth points. In the node portion, roots and leaves grow, and the leaves extend upward from the surface of the soil SO and can be observed. The lotus leaf has a floating leaf FL that grows in a manner that floats on the water surface, and a standing leaf SL that extends to a position higher than the water surface. At this time, after the occurrence of the standing leaf SL, the propagation of the standing leaf SL occurs. Is observed.

  Thereafter, in the present embodiment, as shown in FIG. 2C, the soil SO rises due to the increase of the roots and the lotus root R around July to August. In the present embodiment, there may be a case where a soil uplift of about 10 cm is confirmed. For this reason, the surface height of the soil and the height of the opening position of the second drain port 2b come close to each other, so that a sufficient water depth cannot be obtained and water shortage may occur. Therefore, in the present embodiment, the second drain port 2b is closed with the drain plug 4b at this timing. Thereby, water WT can be stored in the range of the upper surface height of the container main body 1 from the surface of the soil after the uplift, that is, the water depth can be maintained at about 10 cm. At this time, the amount of water absorbed by the lotus root R further increases and transpiration proceeds, so that irrigation is performed as necessary.

  Thereafter, in the present embodiment, when it reaches around the end of August, it becomes an enlarged period, the growth of the lotus root R is slowed down, and the edible portion of the lotus root R is enlarged.

  In the present embodiment, harvesting is possible from around September to October. When harvesting, for example, as shown in FIG. 2D, the first drain port 2a and the second drain port 2b are opened to drain the stored water WT. Thereafter, the leaves SL and FL are cut down. In addition, since lotus root R can be stored in the soil, for example, when lotus root R is cultivated in a plurality of cultivation containers P, it can be harvested at different times, and harvest Since the amount can be adjusted, it is economically advantageous.

  Next, the operation rod 6 used for convenience in harvesting the lotus root R will be described with reference to FIGS. 3 (A) and 3 (B).

  The operating rod 6 is a metal rod-like member bent in a U-shaped cross section, and is attached along the longitudinal direction of the front flange portion 3 of the container body 1. The length of the operation rod 6 is larger than the length of the flange portion 3 in the longitudinal direction. When the operation rod 6 is attached, both ends protrude from both ends of the flange portion 3 and can be gripped by the operator. It is set as a mode.

  As shown in FIG. 3B, the operating rod 6 is fitted so that the flange portion 3 is covered by the inner periphery thereof, and the insertion hole 6 b of the operating rod 6 is aligned with the mounting hole 3 b of the flange portion 3. . Then, after inserting the bolt 6a from the insertion hole 6b opened on the upper surface side of the operation rod 6, it passes through the mounting hole 3b of the flange portion 3 and the insertion hole 6c opened on the lower surface side of the operation rod 6, The nut 6d is screwed. Thereby, the operating rod 6 can be fixed to the container main body 1. When the operation container 6 attached to the container body 1 is used to turn the cultivation container P upside down, the operation load is uniformly applied to the entire lower end surface of the flange portion 3 together with the reinforcing rib 3a. The container body 1 can be prevented from being flexible and the harvesting operation can be facilitated. Thus, in this embodiment, the operating rod 6 functions as an operating member by being attached to the container main body 1 as described above.

  Here, a modified example of the operating rod will be described with reference to FIG. FIG. 4A is an enlarged cross-sectional view showing a first modified example of the operating rod, and FIG. 4B is an enlarged cross-sectional view showing a second modified example of the operating rod.

  As shown in FIG. 4 (A), the operating rod 16 of the first modified example is a metal rod-like member (sometimes referred to as C-shaped steel) bent into a C-shaped cross section, and FIG. It is attached to the flange portion 3 of the container body 1 in the manner shown and described above. In the operation rod 16 of the first modified example, the tip of the lower surface is bent upward to form a flange shape. When an operation of turning the cultivation container P upside down using the operation rod 16 is performed, the operation load is the operation rod 16. Since the flange portion at the tip of the lower surface of the container is applied to the plurality of reinforcing ribs 3a formed on the inner periphery of the flange portion 3 of the container body 1, the load uniformity is inferior to the operating rod 6 shown in FIG. The flexibility of the container body 1 can be suppressed, and even in this way, the lotus root harvesting operation can be made easy.

  As shown in FIG. 4B, the operation rod 26 of the second modified example includes a wooden thick plate-like operation member 26 </ b> A attached to the upper surface of the flange portion 3 of the container body 1, and the flange portion 3. It is also provided with the same wooden thick plate-like support member 26B attached to the lower surface. The operation member 26A is longer than the length of the flange portion 3 in the longitudinal direction. When the operation member 26A is attached, both ends protrude from both ends of the flange portion 3 and can be gripped by the operator. It is set as a mode. On the other hand, the length of the support member 26 </ b> B substantially matches the length of the flange portion 3 in the longitudinal direction. The operation member 26A and the support member 26B may be made of metal. The operating rod 26 of the second modified example is such that the operating member 26A is first placed on the upper surface of the flange portion 3 so that the insertion hole 26b opened in the operating member 26A and the mounting hole 3b opened in the flange portion 3 are aligned. The bolt 26a is inserted through the insertion hole 26b of the operation member 26A together with the washer 26a '. Thereafter, the support member 26B is brought into contact with the flange portion 3 from below so that the bolt 26a is inserted through the insertion hole 26c provided in the support member 26B. Thereafter, the washer 26d 'is inserted into the bolt 26a, and the nut 26d is screwed into the bolt 26a. When the operation container 26 attached to the container main body 1 is used to turn the cultivation container P upside down, the operation load is applied to the entire lower end surface of the flange portion 3 together with the reinforcing rib 3a by the support member 26B. Since it takes uniformly, it can suppress that the container main body 1 flexes, and can perform a harvesting operation easily. That is, although the operation rod 26 of the second modification is inferior in that the number of parts is larger than that of the operation rod 6 shown in FIG. 3, the same effect as the operation rod 6 shown in FIG. 3 can be exhibited.

  In the present embodiment, the operation rod 6 is attached only to the front side of the container body 1, but the operation rod 6 may be attached to both the front and rear sides. In addition, the operation basket 6 may not be attached, and the cultivation container P may be turned over without using the operation basket 6 to harvest the lotus root R.

  Next, a procedure for harvesting the lotus root R by the cultivation container P to which the operation basket 6 is attached as described above will be described with reference to FIG.

  First, as shown in FIG. 5 (A), in a state where the operation rod 6 is attached to the container body 1, the soil on the side where the operation rod 6 is attached (in the region indicated by the symbol SOa in FIG. 5 (A)). To some extent. Thereby, while the cultivation container P is reduced in weight, the center of gravity of the cultivation container P is displaced to the rear side, and the operation of turning over with the operation rod 6 can be facilitated. In addition, in performing the operation which turns the cultivation container P upside down, it is not necessary to discharge the soil.

  Subsequently, as shown in FIG. 5B, an operation of turning the cultivation container P upside down by two workers FM is performed. At this time, one operator is arranged at each end of the operation basket 6, and both ends of the operation basket 6 are simultaneously moved so as to swing the cultivation container P in the direction of the arrow with the rear bottom of the container body 1 as a swing axis. By operating it, the cultivation container P can be turned over relatively easily.

  Then, as shown in FIG. 5C, the grown lotus root R together with the soil SO is discharged from the cultivation container P, and the lotus root R can be easily taken out.

  After the lotus root R is discharged, the cultivation container P can be washed and reused. At this time, the useful life can be extended by storing the product away from direct sunlight.

  As described above, according to the present embodiment, the cultivation container P is provided at a position at a predetermined height from the bottom surface of the portable container body 1 with the top surface opened and the side surface of the container body 1. A first drainage port 2a capable of discharging the water in the container body 1, a soil storage space capable of storing soil for cultivation plants such as lotus root R formed below the first drainage port 2a, and a first And a drain plug 4a capable of setting the drain port 2a to either the open state or the closed state. As a result, it is possible to provide a cultivation container in which lotus root cultivation can be managed in a place with good workability, not in a swamp, and a harvesting operation can be easily performed. That is, lotus root can be cultivated by a simple method, and the lotus root can be harvested by a simple method of turning the cultivation container P upside down. Cost can be reduced. Furthermore, for lotus roots to select a cultivation place, by using this cultivation container, it can be cultivated anywhere as long as workability is good, regardless of the cultivation place. it can.

  Moreover, according to this embodiment, it is provided on the side surface of the container body 1 between the height at which the first drainage port 2 a is provided and the upper end of the container body 1 to discharge the water in the container body 1. Since it has the possible 2nd drainage port 2b and the drainage plug 4b which can make the 2nd drainage port 2b either a plugged state and a plugged state, it keeps the amount of water in lotus root cultivation constant That is, since the water depth can be kept constant, soil management becomes easy. Further, even when the soil rises and the height of the soil surface rises due to the growth of the lotus root, it is possible to store a certain amount of water by closing the second drain outlet. As a result, lotus root can be cultivated more easily.

  Moreover, according to this embodiment, since the 2nd drainage port 2b is 5-15 cm higher than the 1st drainage port 2a, and is provided in the position 5-15 cm lower than the upper end of the container main body 1. In the lotus root cultivation process, the amount of water can be managed more appropriately.

  Moreover, according to this embodiment, since the 1st drainage port 2a is provided in the position of the height of 15-25 cm from the bottom face of the container main body 1, the planted lotus root can be made to grow stably. , Lotus root can be cultivated more appropriately.

  Moreover, according to this embodiment, the container main body 1 is formed in the box shape, and the flange part 3 which protrudes outward along an upper end edge is formed. The operation rod 6 extends along the upper end edge of the container body 1 and has a length protruding from the front end portion and the rear end portion of the upper end edge, and supports at least the lower end portion of the flange portion 3. Thus, it attaches to the flange part 3 so that attachment or detachment is possible. As a result, the lotus root cultivated in the cultivation container can be harvested by turning the cultivation container upside down. However, since the operation of turning it over can be facilitated, the efficiency of the harvesting work can be improved. Moreover, since the load generated by the operation of the operation rod can be dispersed, the deformation of the container body 1 can be suppressed, and the harvesting operation can be performed more easily.
