Description

  The present invention relates to a novel crossing prevention or crossing prevention member, plant cultivation device, and plant cultivation method used for plant research such as genetic recombination by collecting seeds.

  For example, in pot (pot) cultivation in plant research, the cultivation (nurturing) pots are often cultivated densely because the cultivation space in a laboratory or the like is limited. The problem at this time is crossing or crossing between adjacent plants. In plant research, several strains of the same kind with different strains may be cultivated in the same space. At this time, it is a big problem that crossing occurs until seed collection and the mixed seeds are mixed. In addition, when sampling plants, if adjacent plants are crossed and entangled, the plant body may be damaged when taking out, which is also a big problem.

Therefore, in order to solve these problems, there have been examples in which dice are usually difficult to splint or a cross-prevention cylinder that has been sold has been used. There are the following problems.
(1) Since it is sold in a cylindrical shape, it is bulky at the time of delivery and storage.
(2) It can only handle pots of a certain size.
(3) Since the hole is opened in advance, it is impossible to divert to moisturizing adjustment immediately after seedling transplantation.

  The present invention has been made in consideration of the above-mentioned matters. For example, it can cope with cultivation of plant pots of various sizes, and can save space during transportation and storage, or can be further moisturized to prevent crossing or crossing prevention. It aims at providing the member of this, a plant cultivation apparatus, and a plant cultivation method.

  In order to achieve the above object, the present invention is a member for preventing crossing or crossing of plants, comprising a flexible and light-transmitting synthetic resin sheet, and one side end and A locking part and a locked part for connection are formed on one side end part and the other side end part in order to connect the other side end parts facing each other and assemble a cylinder. A crossing prevention or crossing prevention member (Claim 1) is provided.

  Further, in the present invention, the material of the sheet has at least one of an antistatic function, a light amount adjustment function, a transmission wavelength selection function, an antibacterial function, and a water repellent function. A member for preventing or crossing is provided (claim 2).

  Further, according to another aspect of the present invention, in order to prevent crossing or crossing between adjacent plants, each plant is coated with the crossing prevention or crossing prevention member described in claim 1 or 2. The plant cultivation apparatus (Claim 3), and each plant is coated with the member for preventing crossing or crossing described in Claim 1 or 2 in order to prevent crossing or crossing between adjacent plants. A plant cultivation method (claim 4) is provided.

  In the present invention, plant crossing means solid crossing having genetically different traits. Moreover, the intersection of the plants in this invention means the state where an adjacent plant is entangled. Further, in the present invention, connecting one side end portion of the synthetic resin sheet having flexibility and light transmittance and the other side end portion facing this to each other means that both side end portions are overlapped and both side end portions are overlapped. Any of the cases where both end portions are joined without overlapping the portions is included. In the present invention, as a cylinder assembled by connecting one side end of the synthetic resin sheet and the other side end facing the synthetic resin sheet, only when the synthetic resin sheet is rolled into a cylindrical shape and assembled. In addition, the case of assembling into a square cylinder having a polygon in a plan view such as a triangle or a quadrangle in a plan view is included. Furthermore, the place of application of the present invention is limited to cultivation (nurturing) pots (plant pots), planters, fields, and fields as long as crossing or crossing between adjacent plants may occur. is not. Moreover, the plant cultivation apparatus and the plant cultivation method of this invention, for example, when the cultivation pot is used for plant cultivation, the method of covering to cover each adjacent plant with a cylinder is to the cultivation soil accommodated in the cultivation pot. When the tube is pierced, it includes any case where the tube is not pierced into the cultivation soil, and further includes the case where the cultivation pot is covered with the tube.

  The material of the synthetic resin sheet in the present invention is not particularly limited as long as it has flexibility and light transmission, and in order to make it easier for the user to perform deformation work and cutting work, as described above. It is desirable that the material be as thin as possible as long as the cylindrical shape can be maintained. In the present invention, it is also possible to select a material having the following functions shown in (1) to (5) as the material for the synthetic resin sheet. (1) When a material having an antistatic function is selected, seeds and the like can be prevented from adhering to the inside of the cylinder due to static electricity during seed collection. (2) In the case of having a light quantity adjustment function, for example, by arranging tubes with different light passage amounts in the respective plant pots, it is possible to carry out a test according to the light quantity even though the same growth equipment such as lighting is used. (3) When having a transmission wavelength selection function, for example, by arranging tubes having different light transmission wavelengths in the respective plant pots, a growth test for each wavelength is carried out even though the same growth equipment such as lighting is used. This is preferable. (4) In the case of a material having an antibacterial function, deterioration of the plant growth environment such as the propagation of bacteria inside the cylinder is prevented, and it is preferable because a test in the same environment can be established. (5) In the case of a material having a water repellent function, it is suitable because there is no possibility of causing a decrease in strength even when wet.

  According to the present invention, the following effects can be obtained. (1) The crossing prevention or crossing prevention member of this invention is made of a synthetic resin sheet and is an assembly-type cylinder that can be assembled from the sheet. Therefore, it is not an assembled cylinder during transportation and storage. As in the case of paper having a size such as that used in a copier, for example, with the sheet having a locking portion and a locked portion for connection formed on at least one side end portion and the other side end portion. Can be stored. For example, even a plurality of sheets as shown in FIG. 3 can be delivered by an envelope (a necessary number of sheets can be delivered in an envelope). (2) When carrying out pot cultivation using, for example, a cultivation pot for plant cultivation, as described above, conventionally, there is a problem that only a certain size pot (pot) can be handled. By changing the size of the sheet, it is possible to create (assemble) tubes for cultivation pots of various sizes. Furthermore, for example, two sheets of the same size can be connected and used, so that it can be used for various cultivation pots such as a large cultivation pot. (3) As described above, conventionally, since the cross-prevention cylinders that are sold have holes in advance, diversion to moisturizing adjustment such as immediately after transplanting seedlings was impossible, In the present invention, if necessary, the sheet purchaser before assembling can make a ventilation window for moisture retention adjustment on the sheet as needed. For example, the ventilation window can be formed, for example, in the middle of one side end and the other side end of the sheet. It is also possible to purchase a sheet in which such a ventilation window is formed. And after the said purchaser obtains the pipe | tube which has the said ventilation window, during cultivation, the said ventilation window can be opened and closed, for example, and a moisture retention adjustment can be performed, and favorable plant cultivation is possible. (4) It can greatly contribute to the promotion of plant research from the viewpoint of economics such as shortening the working time (labor reduction) of researchers engaged in plant research such as genetic recombination and saving the cost of plant research.

That is, each of the engaging section B has a tongue 10 formed by the slit b _1, b _2, b _3, which are cut in these three linear. In addition, two locked portions B ′ and B ′ that can be locked to the two locking portions A and A are also provided between the one side end 2 and the other side end 3, respectively. It is formed at the same height as B and B. The locked portion B ′ has the same shape as the locked portion B. In the cylinder 4 shown in FIG. 3, the locked portion B ′ also functions as a ventilation window. In other words, the locked portion B ′ has a tongue piece 10 ′ having the same shape as the tongue piece 10 formed by the upper side slit b ₁ and the lower side slit b _{2, and} by opening and closing the tongue piece 10 ′, For example, moisturizing can be adjusted during cultivation. Further, in this embodiment, apart from the locked portion B ′, the cylinder 4 (the sheet 1) has a single tongue piece portion 7 functioning as a ventilation window during cultivation on one side end. In the middle of the two upper and lower locking portions A, A in the portion 2. The tongue piece portion 7 includes a tongue piece 7 ′ formed by an upper lateral slit a ₁ ′ and a lower lateral slit a ₂ ′ cut in a straight line from the side in the vertical direction, and the tip of the tongue piece 7 ′. A straight vertical piece M as a part is formed so as to be flush with the vertical side L of one side end portion 2. Further, if necessary, the purchaser himself / herself can make a ventilation window by making a cut in a necessary portion of the sheet 1 using scissors or a knife. 8 is a bottomed substantially cylindrical cultivation (nurturing) pot (pot) (plant pot) in which the seedling P ′ sprouted on the accommodated cultivation soil 9 is vegetated.

Thus, when cultivating plants by closely arranging cultivation pots (plant pots) 8 adjacent to each other, each cultivation pot 8 has a cylinder (tubular body) 4 for preventing or crossing plants P. Each plant P can be covered with the cylinder 4 by inserting the lower part 4a of the plant and inserting it directly into the cultivation soil 9. That is, in this embodiment, the case where the lower part 4a of the cylinder 4 is pierced into the cultivation soil 9 accommodated in the cultivation pot 8 is adopted as a method of covering the plant P with the cylinder 4. Here, the timing of covering the cylinder 4 is set at the time when seeds are sown, for example, on the cultivated soil 9, or after the seeds sown like the plant P ′ in the cultivation pot 8 shown in FIGS. Or as shown in FIGS. 1 (A) and 1 (B), the plant P is expected to grow to some extent, and the adjacent plants P, P are expected to start to entangle with each other. Whether it is immediately before the start depends on the characteristics of the plant being studied and the purpose of the test. For example, when at least one of the many cultivation pots 8 shown in FIG. 1 includes a plant in which pollen is likely to scatter around, it affects other plants and crosses, so when seeds are sown. Is preferable. Further, in this embodiment, in order to assemble the crossing prevention or crossing prevention cylinder 4, the sheet 1 is overlapped with one side end portion 2 and the other side end portion 3 opposed thereto from the unfolded state. The one side end portion 2 and the other side end portion 3 are connected by a locking portion A and a locked portion B. In this case, the tongue piece 10 of the locked portion B among the locking portion A and the locked portion B constituting the connecting portion that connects the one side end 2 and the other side end 3, that is, , upper horizontal slits b _1, the length S of the lower horizontal slit b ₂ is a 20mm, is formed by a lower horizontal slits b ₂ of length S of the upper horizontal slits b ₁ and 20mm of length S of 20mm Since the tongue piece 10 has a lateral width of 20 mm, in the case of the cylinder 4 of this embodiment formed from one sheet 1, the size of the circumference can be adjusted up to 20 mm. And after use, the cylinder 4 can be disassembled and discarded.

  It is to be noted that a tube thinner than the tube 4 can be formed by connecting the locked portion B ′ that also functions as a ventilation window and the locking portion A.

  FIG. 4 shows a second embodiment of the present invention in which two sheets 1 are used and the two sheets 1 and 1 are connected to each other. 4, the same reference numerals as those shown in FIGS. 1 to 3 are the same or equivalent. In this case, for example, the locked portion B of one sheet 1 (left side in the drawing) and the locking portion A of the other sheet 1 (right side in the drawing) are connected, and the locking portion A of one sheet 1 (left side in the drawing) is connected. By connecting the locked portion B of the other sheet 1 (right side in the figure), a cylinder 4 ′ larger than the cylinder 4 shown in the first embodiment can be assembled. Thereby, diversion to a cultivation pot with an inner diameter and an outer diameter larger than the cultivation pot 8 shown in FIGS. 1-3 is also possible. Similarly, three or more sheets can be connected. Of course, by changing the size of the sheet 1 to be processed, it is possible to create tubes for cultivation pots of various sizes.

  FIG. 5 is a cross-sectional view of a plurality of saw-tooth portions m whose tips are acutely sharpened by processing the lower portion 1a of the sheet 1 including the straight side N having no irregularities as shown in FIG. As a result, it is easy to directly insert the cylinder 4 into the cultivation soil 9 through the plurality of sawtooth portions m arranged in an annular shape, and the inserted cylinder 4 is a brell. 3 shows a third embodiment of the present invention configured to be able to hold the insertion state firmly against disturbances such as vibrations. 5, the same reference numerals as those shown in FIGS. 1 to 4 are the same or equivalent.

  In addition, the shape of the latching | locking part A and the to-be-latched part B is not restricted to the shape shown to said each embodiment, In this invention, what was deform | transformed into various shapes is applicable.

  Moreover, in this invention, it is also possible to provide a lid | cover on the top part of the pipe | tube (tubular body) 4 installed, for example in the cultivation pot 8 shown in FIG. 2 as needed. That is, in FIG. 2, by installing a lid (not shown) that covers the upper opening 4b of the tube (tubular body) 4, it is possible to prevent an external factor such as an insect from entering the growing environment. . In addition, there is no limitation in particular as a raw material of the said lid | cover, For example, it can form with the same material (same material as the synthetic resin sheet 1) as the cylinder (tubular body) 4. In addition, the lid may have a shape that can seal the tube (tubular body) 4, but for example, by making it a mesh shape or a perforated shape, the external factor can be eliminated while ensuring air permeability.

  Furthermore, in this invention, it is also possible to provide the taper-shaped bottom face member supported by the cultivation pot 8 on the bottom of the pipe | tube (tubular body) 4 etc. which are shown, for example in FIG. The bottom member has a hole through which a plant can penetrate at the center (tapered top), and a collection area having a substantially horizontal or U-shaped longitudinal section is provided on the outer periphery. FIG. 6 shows a bottom surface member 20 provided with a collection area having a substantially U-shaped longitudinal section on the outer peripheral portion. In FIG. 6, the bottom surface member 20 includes a hat-like tapered portion 21 having a truncated cone shape, and an outward flange (edge portion) 22 that forms a lower opening 21 a of the tapered portion 21. The flange 22 has an annular surface portion 23 and an outer peripheral surface portion 24 rising from the outer periphery of the annular surface portion 23. The annular collection area having a predetermined width is constituted by the flange 22. H is a plant through hole that constitutes the upper opening of the tapered portion 21.

  Thus, the bottom member 20 is installed (the cylinder 4 is mounted on the annular surface portion 23 of the flange 22). In this case, it is preferable that the lower end of the tube 4 and the outer peripheral surface of the lower portion 4a of the cylinder 4 are in contact with the upper surface of the annular surface portion 23 of the flange 22 of the bottom member 20 and the inner surface of the outer peripheral surface portion 24 of the flange 22, respectively. And when the seed 25 which set in the cylinder 4 falls by installing the bottom face member 20, after the seed 25 falls on the upper surface 21c of the taper part 21 of the bottom face member 20, the said seed | tip of the outer peripheral side is followed along the inclination. For example, the seeds can be easily collected without being attached to the cultivation soil 9 of the cultivation (nurturing) pot (growth pot) 8 shown in FIG. The support form of the bottom member 20 with respect to the cultivation pot 8 can be set as appropriate.
