In addition, since the vegetable support plate 10 is made of Styrofoam, which has a relatively high foaming rate, it has the hardness and rigidity necessary to support salad vegetables, while allowing roots to enter during the growth process and allowing the roots to spread and grow. It does not prevent you from doing so. Styrofoam has the advantage that no harmful bacteria are propagated to vegetables.

Further, since the outer surface of the support frame 12 is coated with an antifungal agent or an antifungal agent, it is possible to prevent the formation of mold, and the support frame 12 can be used repeatedly. Further, since the styrofoam floats on water, it can be left floating on the liquid fertilizer without the support means of the vegetable support plate 10 in the step of germinating the salad vegetables, for example. Further, since the support frame 12 has a size suitable for growing one salad vegetable to a size up to the intermediate stage of the growth process, a plurality of germinated seeds in one hydroponics bed 2 with a time lag of a predetermined period. When the group's salad vegetables are continuously grown over time, the distance between adjacent salad vegetables is the minimum distance required for each growth stage of each group's salad vegetables, i.e., this distance for groups with smaller leaves. In the small and pre-harvest groups, the size can be adjusted to the necessary and minimum size that does not interfere with the growth of adjacent salad vegetables. As a result, the surface of one hydroponics bed 2 can be efficiently used through the production cycle of a plurality of groups of salad vegetables that are grown at different times using one hydroponics bed 2, and It is possible to improve efficiency.

Further, since the supporting frame has a size for one salad vegetable, it is possible to individually inspect the root growth condition,
The vegetable support plate can be raised and lowered according to its growth state. Further, according to the vegetable transport unit of the present embodiment shown in FIGS. 7 and 8, it is possible to assemble and transport salad vegetables that are easily harvested using the above-described vegetable hydroponics device as they are. . The salad vegetables thus harvested are securely fixed in the through holes 16 of the vegetable support plate 10, and the vegetable support plate is securely fixed at the flange portion of the insertion port of the lid portion. Since it is attached to the container body having a size that prevents the rollover, the salad vegetables can be maintained in an upright posture. This means that at harvest, the leaves will grow laterally and greatly, with a length of 2 leaves at the bottom.
It can reach 0 cm and prevent leaf damage, which is 40 cm in size for the whole salad. Further, the stems and roots of the salad vegetables harvested by the above method are not damaged by the harvest, and the roots absorb the hydration liquid in the root container well, so that the freshness of the salad vegetables is the same as when cultivating. Can be maintained.

Further, the insertion opening of the lid portion is sized so that the root portion of the salad vegetable can easily pass therethrough, that is, the support frame 12
Since it is almost the same size as the opening 14 of the, the root part can be easily inserted, and further, the vegetable support plate can be simply inserted into the insertion opening of the lid part, which facilitates the assembly work of the vegetable transport unit. Is. Further, the flange 32 of the lid portion 24 is fitted into the groove 19 of the vegetable support plate 6 in a liquid-tight manner, and the vegetable support plate 10 is made of non-permeable polystyrene foam. Since it is liquid-tightly attached to the container body 26, leakage of the liquid in the container 22 is further prevented. In addition, since the vegetable support plate 10 holds the vegetable support plate 10 at a distance from the bottom surface of the root container 20, the vegetable support plate 10 itself has an irregular shape,

It is installed at a position below the second opening 14. Furthermore, in the above-mentioned apparatus for hydroponic cultivation of vegetables, the support frame 12 is coated with a fungicide with a nitrogen-containing system and ethanol, but if the component does not dissolve in the liquid fertilizer, other protective solutions are used. It may be a fungicide. Further, the outer surface of the vegetable support plate 10 may be similarly coated with a fungicide.

Further, the salad vegetables grown by the above-mentioned vegetable hydroponic cultivation apparatus are designed to be shipped together with the roots. However, after harvesting by the above method, the roots may be cut off and shipped if necessary. . Also, as an example, it has been described that one salad vegetable is grown on one vegetable support plate, but in addition to sunny lettuce, bok choy, Mizuna, etc., a plurality of stems such as watercress, parsley, etc. You may cultivate a part and a root as one cultivation unit, and use it for growing vegetables having a split-shaped root. Further, it can be used for growing vegetables, such as wasabi, which also eats leaves and roots and has a root-shaped root. In this case, the thickness of the vegetable support plate 10 and the size of the through hole 14 are
The size may be set so as not to interfere with the growth of the root of the thick wasabi during the growth process. Further, the size of the opening 14 of the support frame 12,
The outer dimensions of the vegetable support plate 10 may be such that the root of the wasabi can easily pass through. In addition, although it has been described that it is used for leafy vegetables with severely damaged leaves during transportation and sale display, the vegetable transportation unit of the above-described example allows the vegetables to be maintained in a cultivated state even after purchase. For vegetables, such as parsley, which are much larger than the amount that one sales unit eats at one time, freshness can be maintained until they are consumed by supplying water to the vegetable transportation unit after purchase. In this case, parsley and the like may be picked up from the vegetable transport unit in the required amount each time.

Further, the vegetable transport unit of the above embodiment is
About one vegetable growing plate 10, one salad vegetable is grown and conveyed, but for example, it may be used for watercress or parsley that sells a plurality of stems together, and in this case, the vegetable hydroponics device is used. One cultivation unit may be matched with one sales unit. Furthermore, the vegetable transport unit of the above-described embodiment has been described as an example for transporting leafy vegetables that eat leaves such as salad vegetables, but, for example, it is used for vegetables that eat leaves and roots such as wasabi. Good. in this case,
