Description

The present invention relates to a plant cultivation device, and more particularly, to a plant cultivation device capable of cultivating plants in a sanitary manner without using soil.

In recent years, cultivation apparatuses for cultivating plants by directly supplying water to the plants without using soil have been developed. For example, in Patent Document 1 below, nutrient water located at a lower water level than a microporous fired body having a water-absorbing ability is supplied to the microporous fired body by capillary force, and the inside of the microporous fired body is supplied. There is disclosed a cultivation device for directly sucking nutrient water retained in a plant root into a plant. According to the cultivation apparatus,
According to the company, it does not require maintenance, saves water, and does not require soil, making it easy to miniaturize and indoor cultivation.

However, when the cultivation apparatus is downsized for indoor use (for example, to the extent that it is placed on a table or the like), the volume of the microporous fired body is reduced, and as a result, it can be held inside the microporous fired body. The amount of water is reduced, and the supply of water only by capillary force from a low water level makes it difficult to supply water uniformly to the whole of the microporous fired body, especially for plants having a relatively large water demand. However, there is a problem that it may be difficult to sufficiently supply water to the plant evenly.

Patent Document 2 below discloses a tank for storing water, a holder provided on an upper part of the tank, and a microporous which is detachably attached to the holder and absorbs water in the tank through a string. Disclosed is a water-saving type plant cultivation device that includes a planting member made of a bodily body, is easily miniaturized, and is suitable for indoor cultivation.

However, even in the plant cultivation device described in Patent Literature 2, it is difficult to uniformly supply water to the entire planting member only by supplying water through a string, and has the same problem. Further, in this plant cultivation device, when the water in the tank becomes dirty, the soiled water is directly absorbed through the string, so that there is a problem that the planting member is easily stained by adhesion of various bacteria and the like. Was.
