Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an apparatus for hydroponics of vegetables,
A method for growing leafy vegetables (hereinafter referred to as "leaf vegetables") mainly using the leaf portion as an ingredient by the hydroponic cultivation apparatus;
Further, the present invention relates to a vegetable transport unit for transporting the same.

[0002]

2. Description of the Related Art Leaf vegetables, such as leafy vegetables, for example, sunny lettuce, endive, etc., which are large in one plant and are shipped in units of one plant, when growing, the leaves of adjacent plants are mutually separated until the leaf vegetable is harvested. To avoid interference, separate the strains from each other,
It was raised by soil planting or hydroponics. When cultivating by soil planting, for example, "planter vegetable making" (incorporated association)
As described in Agriculture, Mountain and Village Cultural Association, pages 112 to 113), lettuce such as sunny lettuce is thinned out at the time when cotyledons are completely opened, and then several dozens later. Planted and raised at centimeter intervals. On the other hand, when growing by hydroponics, for example, as described in “Guide to Hydroponic Culture in Institutional Horticulture” (Japan Institute for Horticulture, p. 134), for example, in the case of lettuce, Use a urethane mat for hydroponic seedlings, sprinkle 2-3 grains per block, and after germination,
It is described that one block is thinned out. After that, planting is performed by burying one block at a time in a planting hole of a dedicated cultivation bed set in the channel.

[0003] When cultivating leafy vegetables using such an apparatus, by the time of harvesting, the base of the vegetable stem passes through the planting hole in the cultivation bed, and the leaf portion is located above the cultivation bed. The roots will spread below and grow, and when harvesting, they will either cut the roots of the vegetable stalks one by one, or otherwise pull them out of the vegetable planting holes with force and cut them. The remaining roots were removed. In addition, the leafy vegetables thus harvested have been shipped immediately or before they are damaged without any damage.

[0004]

In hydroponic cultivation, facilities are more expensive than soil planting, and the use efficiency per cultivated area becomes important. However, for example, leaf vegetables have no commercial value unless the size and total amount of leaves of a single strain are constant, and until they grow to that extent, for example, in the case of sunny lettuce, an average of about 60 days a year It is unavoidable to spend the training period. In the case of hydroponic cultivation, particularly in the summer, there is a high possibility that a disease will occur about 45 to 50 days after germination. However, if you try to harvest before the disease-prone period, you have not grown enough to ship. In addition, especially in the summer season, only the stem grows high and the growth of the leaves is delayed, and if the size and the amount of the leaves that can be shipped are obtained, so-called "bolting" occurs, and the commercial value decreases. On the other hand,
As in the related art, it takes time and effort to cut or pull out the grown leafy vegetables one by one. Furthermore, after the mowing operation is completed, the vegetable growing panel is removed, the stems of the vegetables remaining in the vegetable planting holes and the roots attached to the bottom surface of the vegetable growing panel are removed, or when the vegetables are pulled out. It was necessary to remove the cut roots from the hydroponic bed, and such cleaning work was a great deal of labor and time.

[0005] Furthermore, once the root portion is cut off, leaf vegetables begin to be damaged, the freshness is lost during shipping and transportation and during the sales process, and the leaves become darkened or wilted. descend. In particular, this problem is remarkable in salad vegetables which emphasize freshness of leaves. Furthermore, leaves that are as fresh as when cultivated have a problem that, unlike withered leaves when the roots are cut off and shipped / sold, leaves tend to break because they are tense, and they are also fresh and easily damaged. . Therefore,
A first object of the present invention is to improve the efficiency of growing and harvesting leafy vegetables by a hydroponic cultivation apparatus. A second object of the present invention is to avoid the occurrence of diseases of leafy vegetables grown by hydroponics, which tend to occur particularly in summer. Further, a third object of the present invention is to cultivate leaf vegetables having a good shape and a high commercial value even in hydroponics in summer. A fourth object of the present invention is to reduce the work of harvesting leafy vegetables. Further, a fifth object of the present invention is to solve the problem of freshness deterioration during transportation and during the sales process, and at the same time, to transport the leaves without damaging the leaves and maintaining the shape of the leaves during cultivation. Is to do so.

[0006]

SUMMARY OF THE INVENTION The present invention relates to a conventional method for planting or germinating plants one by one at a sufficient interval so that the leaves of adjacent leaf vegetables do not interfere with each other during the growth period of leaf vegetables. The technique of growing thinned leaves is the opposite of the conventional method, that is, planting and growing so that the leaves of adjacent leafy vegetables interfere with each other, and harvesting leafy vegetables in a shorter growing period than before. Is what you get. In addition, the leaf vegetables are shipped as one shipping unit. The first to third objects of the present invention include hydroponic cultivation comprising a step of growing a plurality of vegetable strains until harvest at intervals at which leaves interfere with adjacent strains in the course of vegetable growth.

Further, even if a special device is not prepared, the above method can be carried out by planting in a vegetable planting through hole formed in a vegetable planting panel of a conventional device for hydroponics. Further, according to the embodiment of the present invention,
Since the plurality of vegetable strains are 4 strains, it is possible to maintain a close state between the strains and suppress excessive growth of the stem portion, and at the same time, in the outer periphery of the vegetables, each strain is It can maintain the space where leaves grow and promote the growth of leaves.
Further, according to the embodiment of the present invention, the step of growing the plurality of vegetable stocks is performed in a plurality of vegetable planting holes formed close to each other in the vegetable planting panel of the hydroponic cultivation apparatus. Since the plants are planted and grown one by one, a gap is formed between the bases of adjacent stems, which facilitates the work of removing dead leaves.

Further, according to the embodiment of the present invention, since the plurality of vegetable planting holes are four, a close state is maintained between the plants, and more stems are grown than necessary. At the same time, the growth of leaves can be promoted by maintaining the space in which the leaves of each plant grow on the outer periphery of the vegetables. Further, the above method of the present invention is a hydroponic bed for liquid fertilizer, and the number of strains constituting one shipping unit provided on the hydroponic bed and adapted to accommodate a nursery bed for vegetable planting. And a vegetable support material having a plurality of vertical through holes corresponding to, the plurality of through holes, the roots so that the leaves interfere with each other between adjacent plants in the process of growing leaf vegetables. It can be carried out by an apparatus for hydroponic culture of leaf vegetables arranged at intervals allowing for planting. Further, according to the embodiment of the present invention, the plurality of through holes are four, and the four through holes are arranged at equal intervals on the same circumference, so that they are adjacent to each other. The tightness between the strains can be made uniform, and thus each strain can be grown uniformly. Further, the fourth object of the present invention can be achieved by the apparatus for hydroponic cultivation of leaf vegetables, wherein the vegetable support material supports one shipping unit of vegetables. Since the vegetable support material supports leaf vegetables in one shipping unit, the vegetable support material can be shipped together with the vegetable support material, and the grown leaf vegetable is cut off between the base and the root or pulled out from the through hole of the root. The labor for harvesting can be reduced, and the cleaning of the roots remaining on the hydroponic cultivation bed can be omitted.
