Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a plant cultivation device.

[Conventional technology]

Conventionally, when cultivating plants in flower pots, it is necessary to water them regularly, and depending on the type of plant being cultivated, it is necessary to supply an appropriate amount of water. The use of automatic watering devices can be considered, but these devices are not used by general gardening enthusiasts due to their handling, cost, space, etc., and watering is done by hand.

(Problem to be solved by the invention) As mentioned above, the current situation is that general gardening enthusiasts manually water the plants in an appropriate amount at a cycle that suits the plants they are cultivating. If you neglect to water the plant, it will wither. On the other hand, if you plant it in a container without bottom holes and supply a large amount of water at once to extend the interval between watering, the roots will not be exposed to the air, and the water in the supplied water will die. Oxygen m content decreases rapidly, resulting in root rot.

Therefore, when growing plants in flowerpots, you will need to regularly water them, and if you neglect this care, the plants may wither, or you may have to leave the plants alone for a relatively long period of time when you are traveling or on vacation. If left untreated, the plants would die, which was a big problem for gardening enthusiasts.

The above-mentioned problem is solved by providing a plant cultivation device which is composed of an open container body, and has a cultivation section formed on one side and a water chamber formed on the other side through the inner wall. be.

[For production]

In the present invention, the cultivation area is formed on one side and the water chamber is formed on the other side through the inner wall having minute water-permeable gaps, so when the water chamber is filled with water, water permeates into the inner wall due to osmotic pressure. The water passes through the water-permeable minute gaps in the inner wall and gradually seeps into the cultivation area, and an appropriate amount of water is supplied throughout the cultivation area. The amount of water supplied to the cultivation area is always small and is distributed throughout the entire cultivation area, making it possible to prevent root rot and other problems caused by excessive water, and watering can be carried out over a relatively long period of time. You can grow plants without.

In addition, when this plant cultivation device is placed outdoors, a drainage hole is provided at the bottom of the cultivation section to prevent rainwater from flowing into the cultivation section and causing more water than necessary to accumulate in the cultivation section. , excess water is drained from this drainage hole,
In addition, the drainage holes can provide ventilation to the bottom of the cultivation area, and the evaporation prevention means provided on the top surface of the water chamber prevents water from evaporating and dirt from entering.
