“Anniversary high-yield production technology mum for tomatoes by low- and multi-stage combined cultivation” (SHP Kanto Regional Agricultural Research and Promotion Council: March 2010)

  The technique described in Patent Document 2 (low-stage dense planting method) is to plant a strain on an elongate submerged hydroponic bed at intervals of 10 cm to 20 cm, but the strain is compared with the hydroponic bed. When planting at a high density, there is a problem that diseases occurring in one strain are likely to spread to other strains. In addition, there is a limit to improving the yield because only low-level fruits are harvested.

  On the other hand, the methods described in Patent Document 1 and Non-Patent Document 1 both achieve year-round cultivation by shifting the cultivation time in the upper and lower stages of multi-stage cultivation to achieve high yield. Such a cultivation method is suitable for the Netherlands where the climate is relatively mild and changes little, but in order to adopt this method in Japan, which is hot and humid in summer, the temperature management of the cultivation facility (house), etc. There is a high possibility that the cost will be high. Moreover, the cultivation apparatus used for this requires the mechanism for raising and lowering the cultivation apparatus arrange | positioned in multiple steps, and there also exists a problem that an apparatus becomes complicated.

  The present invention has been made to solve the above-mentioned problems of the prior art, and is capable of harvesting high-quality fruit vegetables in a high yield within an appropriate period even in an environment where the appropriate period of fruit harvesting is limited. It is an object to provide a method and a cultivation apparatus suitable for the method.

  In order to solve the above-mentioned problems, the present invention is a high-density cultivation using independent pots for each strain, and a multi-stage cultivation method capable of synchronous harvesting (hereinafter referred to as a spatial horizontal division multi-stage synchronous harvest cultivation method) and cultivation. It is an object to provide an apparatus.

  That is, the cultivation method of the present invention is characterized by the use of an independent pot for each strain, low-stage dense planting harvested at low stages of flower bunches, low-stage dense planting multi-stage and synchronous harvesting. Specifically, the step of arranging the seedlings planted in the pot in a predetermined horizontal direction at a predetermined interval and similarly arranging the rows of pots arranged in the horizontal direction at intervals of 60 cm or more and 120 cm or less in the vertical direction. A step of centering in a state in which the flower bunches grow more than the stage florets, a step of growing until the flower bunches become fruit bunches, and a step of harvesting fruit bunches at the same time for the pot rows arranged above and below. The growing step includes a step of supplying water and fertilizing the stock planted in the pot as appropriate.

Moreover, this invention provides the cultivation apparatus suitable for the said space horizontal division | segmentation multistage synchronous harvest cultivation method.
That is, the cultivation apparatus of the present invention comprises a pot support means for placing a plurality of pots planted with plants, a support supporting the pot support means, and a plurality of pots placed on the pot support means. Water supply means for supplying water to each of the pot support means, and the pot support means is composed of at least two upper and lower stages, and the interval between the stages is 60 cm or more and 120 cm or less.

  According to the cultivation method of the present invention, since the independent pot is used, the weight as a whole becomes light, the amount of soil necessary for plant growth can be reduced, and workability is also improved. Moreover, since it is a multistage synchronous harvest, fruit vegetables can be harvested in a short time and with a high yield in a suitable cultivation period considering the physiology of the plant. In addition, since it can be harvested in a short time, the facility space can be used effectively. In other words, it is possible to cultivate the same kind or different fruit vegetables with a high yield by varying the optimum cultivation period.

  Further, according to the cultivation method of the present invention, since it is an independent pot cultivation and harvested in a short period, there is no risk of encountering environmental stress as in a long-term multistage cultivation, and management of diseases and the like is easy. Furthermore, according to the cultivation method of the present invention, the fruit at the appropriate time and in the lower stage is harvested, so that the harvested fruit is high quality and heavy in weight, so that the marketable fruit rate can be improved.

  The cultivation apparatus of the present invention is a cultivation apparatus suitable for the above cultivation method, and can effectively utilize the facility because the facility space can be utilized in multiple stages. In the case of two stages, the distance between the stages is as narrow as 120 cm or less, so that the work can be performed without using a high-altitude work cart or the like, and management is easy.

  Moreover, the cultivation apparatus of the present invention is provided with an open / close valve in each stage water supply system and a check valve between the water supply systems, so that when multiple stages are used simultaneously, only one stage is used, or one water supply system fails. Various usage forms such as diversion of other water supply systems can be provided.

  Furthermore, the cultivation apparatus of the present invention is provided with at least an attracting means for attracting the growth of the lowermost plant, so that it does not collide with the pot positioned above it or its supporting means, and does not shade them. Plants can be grown.

The figure which shows the relationship between a pot and a pot support means Diagram showing water supply means Diagram showing attracting means Diagram showing the relationship between the inducement means and the upper stage of the device

Hereinafter, one embodiment of a cultivation device of the present invention is described with reference to drawings.
The cultivation apparatus 1 shown in FIG. 1 is a cultivation apparatus for multi-stage cultivation, and mainly includes a plurality of support columns 10 and 11 extending in a vertical direction, a pot support unit 20 in which a pot 50 in which plants are planted is placed, and a pot support unit 20. The water supply means 30 for supplying water to the pot placed in the water and the attraction means (attraction bar 41, attraction string 45) for guiding the growth direction of the plant in a predetermined direction are provided. The pot support 20 is provided in at least two stages with a predetermined interval in the vertical direction. In the following description, the case of a two-stage type will be described as an example, but it is possible to have three or more stages.

  In the illustrated embodiment, a plurality of pairs of support columns 10 and 11 are provided at both ends of the apparatus 1 and a plurality of pairs with the pot support 20 interposed therebetween. When the length of the apparatus in the longitudinal direction is short, a pair of intermediate struts may be used or may be omitted. Moreover, it is good also as a pair of support | pillars instead of one at both ends. The struts 10 and 11 are fixed on a pedestal 12 or the like so as not to easily fall down.

  The pot support 20 is fixed to the support columns 10 and 11 in a plurality of stages in the vertical direction. The interval between the steps differs depending on the target fruit and vegetables, but in any case, it is preferably in the range of 60 cm to 120 cm in order to perform low-stage dense planting cultivation. In general, fruit vegetables such as tomatoes have multi-stage bunches (the stage of the bunches is not related to the number of stages of the cultivation apparatus), but by setting the step interval of the pot support 10 within the above-described range, the low-stage fruit Can be reliably grown, and workability at a relatively low position is possible. In particular, in the case of two stages, it is possible to dispense with a dedicated platform for working at high places.

  Since the structure of the pot support 20 at each stage is common, only one pot support 20 will be described. The pot support unit 20 includes a plate-like member 21 on which a pot is placed and a pair of rod-like members 22 positioned immediately above the plate-like member 21. As shown in FIG. 2, the plate-like member 21 is fixed to a fixing member 15 whose longitudinal direction is provided on each column 10 so that its main plane is substantially horizontal.

  In the present embodiment, as a particularly preferable form, the plate-like member 21 has an elongated reinforcing member 23 fixed on the fixing member 12 along the longitudinal direction of the apparatus, and the plate-like member 21 is fixed to the reinforcing member 23. Yes. Here, the reinforcing member 23 is a pipe-shaped circular member, and the plate-like member 21 is rotatably fixed around the cylindrical reinforcing member 23 as an axis, so that the main plane of the plate-like member 21 is changed from horizontal to vertical. Can be changed. Since the plate-like member 21 is rotatable, workability of pot placement work or pick-up work or fruit harvesting work can be improved. Note that the plate-like member 21 only needs to be rotatable with respect to the support column 10 and may be directly attached to the support column without using the reinforcing member 23.

  Further, the pot support portion 20 arranged in the first stage may be supported by a fixture directly fixed to the floor except for both ends of the apparatus, and in that case, the fixing member 15 fixed to the column 10 can be omitted. .

  The rod-shaped member 22 is made of, for example, a metal pipe, and both ends in the longitudinal direction thereof are fixed to the columns 10 positioned at both ends via a fixture. In the middle part in the longitudinal direction of the apparatus, the support 10 may be fixed with a simple wire or the like, or a fixing device similar to both ends may be provided.

  The distance between the pair of rod-like members 22 is designed to be wider than the width of the pot placed on the pot support 20. The distance in the height direction between the plate-like member 21 and the rod-like member 22 is designed to be approximately the same as the height of the pot. As a result, as shown in FIG. 3, the sheet 25 is arranged so that the plate-like member 21 is the bottom surface and the side surface between the plate-like member 21 and the rod-like member 22 is a space for receiving the pot 50. The As a structure for fixing the rod-shaped member 22 to the support column 10, it is also possible to adopt a structure in which the height h of the rod-shaped member 22 and the distance d between the pair of rod-shaped members 22 are variable. It is possible to correspond to the pot 50. However, it is important that the plant placed in the lower part of the apparatus is not shaded by the sheet 25 or pot.

  The water supply means 30 is provided between a flexible water supply pipe 31, a supply source 32 that supplies water (including liquid containing fertilizer and the like) to the water supply pipe 31, and the water supply pipe 31 and the water supply source 32. It consists of a plurality of valves 33-35. The water supply pipes 31 are arranged along the longitudinal direction of the pot support portions 20 of the respective stages, and are used to supply water to pots placed on the pot support portions 20, and as shown in FIG. A thin tube 35 with a nozzle for supplying water is connected. Water is supplied by inserting the tip of the nozzle of the narrow tube 35 into the pot.

  The water supply pipe 31 is connected to the water supply source 32 via opening / closing valves 33-1 and 33-2 and electromagnetic valves 35-1 and 35-2 for each stage, and is opened and closed between the water supply pipes 31 of each stage. A valve 33-3 and a check valve (backflow prevention valve) 34 are connected, and an open / close valve 33-4 is connected between the water supply pipe 31 closer to the electromagnetic valve 35. When cultivating in two stages, only the electromagnetic valve 35-1 connected to the first stage water supply pipe 31 may be opened, and the open / close valves 33-1 to 33-4 may be opened to supply water. Water may be supplied from the water supply source by opening both the electromagnetic valves 35-1 and 35-2 connected to the first and second water supply pipes. Moreover, when cultivating only in the 1st stage, it is also possible to supply water with only the opening / closing valve 33-1 opened and the other opening / closing valves 33-2 to 33-4 closed. When cultivating only in the second stage, the electromagnetic valve 35-2 and the open / close valve 33-2 are opened, or the electromagnetic valve 35-1 and the open / close valves 33-4, 33-2 are opened to supply water.

  The attracting means has a function of attracting the growth direction of the plant planted in the pot in a predetermined direction and preventing the plant placed on the lower stage from colliding with the pot support part 20 on the upper stage as a result of the growth. An attracting bar 41 disposed along the longitudinal direction of the pot support 20 above the pot support 20 and an attracting bar support 42 for movably supporting both ends of the attracting bar 41 with respect to the columns 10 on both sides of the apparatus. Including. For example, as shown in FIG. 5, the attracting rod support portion 42 includes a first support portion 421 that can move in the vertical direction with respect to the support column 10, and a direction (horizontal) with respect to the first support portion 421. And a second support portion 422 that slides in the direction), and the attracting rod 41 is fixed to the tip of the second support portion 421. With this mechanism, the attracting bar 41 can freely change the vertical position with respect to the pot 50 placed on the pot support 20 (plate member 21) and also change the position of the plate member 21 in the width direction. be able to.

  As shown in FIGS. 5 and 6, an attraction string 45 is stretched between the plant planted in the pot and the attraction bar 41, and the plant is attracted in the direction in which the attraction string extends. ing. Although the position of the attracting bar 41 in the height direction varies depending on the type of plant, as shown in FIG. It may be the same as or higher than member 21). The height can be adjusted by moving the first support portion 421. If the height of the attracting bar 41 is higher than that of the upper plate member 21, the upper pot 50 or the sheet 25 prevents at least the sheet 25 from growing in the shade of the planted portion of the grown lower step. It is important that the horizontal distance between and the attraction string 45 is 5 cm or more. The position of the attracting bar 41 in the horizontal direction can be adjusted by moving the second support portion 422.

  Since the attracting bar 41 is movable as described above, the plant growing point which is increased by changing the position of the attracting bar 41 is accompanied by the growth of the plant that changes with the season, and the bottom surface of the pot support 20 on the upper stage. It is possible to prevent the growth from being inhibited. Moreover, it can prevent the planted part of the grown lower stage from being shaded.

Next, the usage method of the said cultivation apparatus is demonstrated.
First, as a preparation stage, the cultivation apparatus 1 is assembled in a facility such as a house with a predetermined interval (interval perpendicular to the longitudinal direction of the cultivation apparatus) so that the longitudinal direction of the apparatus is the east-west direction. The interval is appropriately determined in consideration of the angle of sunlight and the height of the cultivation device.

  Next, a sheet 25 as shown in FIG. 3 is laid on the plate-like member 21 of the pot support 20 at each stage, and the pots 50 in which seedlings are planted are arranged on the sheet 25 at a predetermined interval. The end of the sheet 25 is hooked on the rod-shaped member 22 and fixed from above with a clip or the like. The sheet 25 functions as a receiving part that prevents the pot 50 from toppling over, and also functions as a drainage receiver.

  On the other hand, as shown in FIG. 5, one end of the rope 45 is fixed to the attracting bar 41 at a position corresponding to the pot 50, and the other end is fixed to the trunk portion near the root of the seedling with a clip or the like. The rope 45 is pasted between the rod 41. Further, the water supply pipe 31 is routed along the longitudinal direction of the pot support portion 20 at each stage, and the nozzle portion of the thin tube 35 with a nozzle connected to the water supply pipe 31 is pierced into the culture medium of the pot 50 so that water can be supplied. After that, fruit vegetables are grown until harvesting while appropriately supplying water and fertilizing through the water supply pipe 31.

  Further, during the process of plant growth, the position of the attracting bar 41 is adjusted in the vertical and forward / backward directions as necessary, and the growth point of the plant that has grown is brought into contact with the upper pot support 20 to inhibit the growth. Prevents the plant from covering or covering. At this time, by adjusting the length of the rope 45 clipped to the base, the rope 45 can always be stuck between the base and the attracting bar 41.

  The cultivation apparatus of the present invention can enable pot-set multi-stage synchronous harvest cultivation with a simple structure. In addition, since the intervals between the steps are within an appropriate range, workability is good. In addition, by providing an open / close valve in each stage water supply system and a check valve between each water supply system, even if there is a failure in one water supply system, water supply continues from the water supply system in which there is no failure in that water supply system Is possible.

  Although the cultivation apparatus of this invention is suitable for the cultivation method of this invention demonstrated below and the space horizontal division | segmentation multistage synchronous harvest cultivation method, it is also possible to use it for other cultivation methods. For example, you may grow using only one part among multistage pot support parts, and the density etc. of the pot arrange | positioned at one stage can be changed according to the kind and kind of plant. In addition, the material and fixing method of each member described in the above embodiment are not limited to the above embodiment, and it goes without saying that known materials and mechanisms can be adopted as long as they have similar functions.

  Next, the cultivation method of the present invention will be described. The cultivation method of the present invention preferably uses the cultivation apparatus described above, but is not limited thereto, and has cultivation means having a multi-stage pot support section and means capable of supplying water to each stage pot. Any apparatus can be used. Below, the cultivation method is demonstrated to the case where the cultivation apparatus 1 of FIG. 1 is used as an example.

  First, as described above, seedlings grown by pot cultivation are arranged between predetermined strains on the pot support portion 20 of the cultivation apparatus 1 installed with predetermined intervals. In addition, the streak is determined in consideration of the incident angle of sunlight at the time of cultivation. Specifically, in the case of winter cultivation from November to February, the length is about 120 to 140 cm. When the incident angle becomes higher than that, it is possible to make the gap narrower than that.

  The interval between individual pots, that is, between the strains, adopts an independent pot method in the method of the present invention, so it can be narrowed to the same interval as the outer diameter of the pot, but from the viewpoint of ensuring air permeability and controlling the vigor. , And preferably about 15 to 20 cm.

  The seedling is preferably planted in an independent pot in a state where about 2 to 3 seedlings are grown separately in a seedling pot. In the cultivation method of the present invention, cultivation is performed in the same independent pot until the fruit is harvested after planting. Therefore, it is preferable to use a cultivation soil that is excellent in water retention, air permeability, and fertilization ability. Specifically, a soil that is excellent in water retention and air permeability and is preferably mixed with an organic material such as peat moss or coconut dust and a clay material such as zeolite, bentonite, or kaolinite that absorbs water in an appropriate ratio. As an example, the bulky soil disclosed in Japanese Patent No. 4865196 can be used.

  As described above, seedlings that have been planted in pots with appropriate soil are placed on the pot support and water is supplied regularly. As explained for the cultivation apparatus, a thin tube 35 with a nozzle of a water supply pipe 31 routed along the pot support 20 is inserted into each pot, and a fertilizer having a predetermined concentration is dissolved from the water supply source 32 as necessary. Supply appropriate amount of water. The amount of water to be supplied and the frequency of water supply are appropriately adjusted according to the capacity of the pot, the environmental temperature, and the growth condition.

  The strain continues to grow while undergoing the flower bud differentiation stage, the fruiting stage, the hypertrophy stage, and the fruit maturation stage. After passing through the fruiting stage after pollination, for example, the strain is cored in a state where it has grown in two or more stages. In the case of tomatoes, the leaves are left on the two-stage inflorescence, and then centered. After that, the plant is allowed to grow while appropriately supplying water and fertilizer, and the fruit is matured and harvested at an appropriate time. In conventional multi-stage cultivation, since different growth stages of plants are mixed, it is necessary to perform fruiting work and leaf removal work in consideration of the tree vigor, but in the cultivation method of the present invention, plants of the same stage are grown. Such work can be omitted.

  Although the period from pollination to harvest varies depending on the type and variety of plants, for example, when tomatoes are harvested in a two-stage fruit bunker, it takes about 50 to 70 days to harvest the first fruit bun after pollination. It takes about 10 days from the bunch harvest to the second bunch harvest.

  As explained above, according to the cultivation method of the present invention, fruit vegetables can be harvested in a high yield in a short period of time, and it is possible to standardize the work without requiring skilled work and management in consideration of the tree vigor. it can.

In order to confirm the effect of the cultivation method of the present invention, the following test was performed.
First, in order to see the relationship between pinching position and planting density, the following three test plots were provided and tomato cultivation was carried out. The implementation period was four months from November to February.
1st section: 2 leaves on the 4-stage inflorescence and core removal 2nd area: 2 leaves on the third-stage inflorescence centering, 3 leaves: 2nd leaves on the second-stage inflorescence

  In each test section, the longitudinal direction of the cultivation apparatus was set to the east-west direction, the striations were 106 cm, and the strains were 15 cm. The position of the first inflorescence of the seedlings used in the test was approximately 45 cm from the top of the medium, and the plant height at harvest was about 145 cm in the first section, about 115 cm in the second section, and about 90 cm in the third section. By the way, for the seedlings in late July, which was sown in early June and planted in late June, the position of the first inflorescence was approximately 60 cm from the top of the medium, and the plant height at harvest was about 105 cm in the 3 wards. It was.

  As a result, it was confirmed that for tomatoes, when low-stage cultivation of the three wards was performed in multiple stages, although there was a difference in cultivar and cultivation season, the interval between each stage should be 120 cm or less even if there was a margin. Moreover, it was confirmed that it should be 60 cm or more in consideration of attracting growth in the front-rear direction with the attracting rod 41.

In each test area, each fruit cluster is fruited, leaving 4 fruits, and harvesting the first fruit cluster about 70 days after pollination, then the second fruit cluster, the third fruit cluster (1st and 2nd wards), Four fruit bunches (1 ward only) were harvested approximately 10 days apart. Table 1 shows the yield of each test plot.

  As can be seen from the results shown in Table 1, when looking at the yield per pot, the greater the number of fruit bunches (1st ward), the greater the yield, but the amount of time until the final harvest. become longer. There was a time difference of about 20 days between the 1st and 3rd wards. Further, since the fruit weight of the fruit bunches decreases as the stage becomes higher, harvesting can be increased by increasing the number of stages by harvesting twice at a low stage. Specifically, when the 3 wards are arranged in two upper and lower tiers, a yield of 3.264 kg (= 1.632 kg × 2) can be expected, so the yield can be improved compared to the 1 ward, and the harvest time is greatly increased. Can be shortened.

  ADVANTAGE OF THE INVENTION According to this invention, the cultivation method and apparatus which can provide a high quality fruit vegetable without a high yield and complicated management and work are provided.
