Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a hydroponic cultivation device used for cultivating plants. Hydroponic cultivation that can promote plant growth and harvest without using It presents the structure of the device.

0002

[Conventional technology]

Conventionally, hydroponic cultivation equipment uses electric circulation equipment, as shown in Figure 2. It is known what was used. The hydroponic cultivation device shown in the figure is a storage tank formed between a bottom wall 12 and an intermediate wall 13 of a cultivation tank 11. A nutrient solution is injected into the liquid chamber 14, and a plant to be cultivated is placed in the nutrient solution chamber 15 formed on the intermediate partition wall 13. A cultivation container 17 planted with a substance 16 is placed in the liquid storage chamber by an electric circulation pump 18. The nutrient solution in 14 is circulated through the nutrient solution chamber 15 and the cultivation container 17, and is further circulated into the liquid storage chamber 14. It is configured to flow.

0003

[Problem that the invention attempts to solve]

The conventional hydroponic cultivation device described above uses an electric circulation pump 18 to store water. The nutrient solution in the liquid chamber 14 is circulated through the nutrient solution chamber 15 and the cultivation container 17, and Since it is configured to circulate the water to the plant, it not only requires electricity, but also Because there is no stagnation of nutrient solution in the roots of the target plants, root elongation is observed, but hairy roots The occurrence of this phenomenon was low, and plant growth was not always sufficient. This invention does not require electrical power equipment and can produce sufficient plant growth. The purpose of this study is to present the structure of a hydroponic cultivation device that can achieve this goal.

0004

[Means to solve the problem]

This invention takes into consideration the problems with the conventional hydroponic cultivation equipment described above, and has developed a cultivation tank. The nutrient solution is injected into the storage chamber formed between the bottom wall and the middle septum, exhibiting capillary action. made of a material, penetrates the middle partition wall, and immerses the lower end in the nutrient solution. The material is made of breathable and water-absorbing material that does not allow the hair roots of plants to pass through. The upper surface of the intermediate partition wall and the water absorbing member is A covered plant support that supports the roots of the plant to be cultivated is placed on the water-retaining sheet. and further includes a lid member that covers the cultivation tank and the plant support. It is something.

[0005] The water absorbing member that penetrates the middle partition wall and has its lower end immersed in the nutrient solution is made of rock wool, Water-retentive material made of sponge etc. and coated on the middle wall and the upper surface of the water-absorbing member The sheets are made of woven fabrics, non-woven fabrics, etc. that have excellent moisture absorption properties and do not allow hair roots to pass through. is used, and a middle partition wall above the storage chamber has a It has a slope of about 1/20 to 1/10 cm, and a communication hole leading to the liquid storage chamber. provided.

[0006]

[Effect]

The hydroponic cultivation device according to the present invention having the above-mentioned structure exhibits capillary phenomenon. The water absorbent is made of a material that penetrates the middle wall and has its lower end immersed in the nutrient solution. The member absorbs the nutrient solution in the liquid storage chamber, raises it, and coats the water absorption member and the intermediate partition wall. The water-retaining sheet disperses the nutrient solution absorbed by the water-absorbing member, and The lid member that covers the cultivation tank holds the hair roots in place to encourage the growth of hair roots. Prevents liquid drying and maintains humidity of 80% or more.

[0007]

【Example】

As shown in FIG. 1, a bottom wall 2 and a middle wall 3 are provided in a cultivation tank 1 to form a liquid storage chamber 4. The lower end of the water absorbing member 5 made of a sponge exhibiting capillary action is attached to the bottom wall 2. The top surface of the water absorbing member 5 and the top surface of the middle partition wall 3 are made to face each other and penetrate the middle partition wall 3. is covered with a water-retentive sheet 6 made of non-woven fabric to support the plants 7 to be cultivated. For this purpose, plant support 8 (200 × 250 × 100 mm) was placed on the water-retaining sheet 6, and then the cultivation tank 1 and the plant support A hydroponic cultivation apparatus was assembled by arranging a lid member 9 to cover 8.

[0008] Strawberries were cultivated using the hydroponic cultivation apparatus described above under the following conditions. Nutrient solution Mixed Hydroponic Fertilizer No. 1 (Main ingredient: KNO ₃ , etc.) Mixed Hydroponic Fertilizer No. 2 (Main ingredient: Ca (NO ₃ ) ₂ , etc.) Prepare (x1) of the nutrient solution and add 2 liters to the cultivation equipment. Then, 10 strawberry (Nyoho) seedlings (seedlings obtained by dividing from runners in June) were planted on plant support 8, and grown in a greenhouse under the following conditions. June to September Maximum temperature 30℃, daytime shading October to December Maximum temperature 25℃, no shading January to February Maximum temperature 23℃, no shading March to April Maximum temperature 30℃, minimum temperature 5℃ Aphids and spider mites Disinfection was performed twice each, and nutrient solution was added at a rate of 1 liter every two weeks.

[0009] As a comparative example, the conventional hydroponic cultivation device shown in Figure 2 with the following specifications was used to produce the same results. A growth test was conducted. Specification summary of conventional hydroponic cultivation equipment External dimensions: 870 x 415 x 315 (mm) Equipment weight: 3.5Kg Total weight: Approximately 8Kg Tank capacity: 45 liters Pump: AC 100V, 50/60HZ, 10/9W

[Effect of the idea]

As described above, the hydroponic cultivation device according to the present invention is arranged between the bottom wall of the cultivation tank and the middle partition wall. The nutrient solution is injected into a storage chamber formed in A water-absorbing member with its lower end immersed in the nutrient solution is placed through the middle partition wall to provide ventilation. A water-retaining sheet made from a material that is both strong and absorbent, and does not allow the hair roots of plants to pass through. The middle partition wall and the upper surface of the water absorbing member are covered by the The plant support is placed on the water-retaining sheet, and the cultivation tank and the plant support are further covered. By having a structure in which the lid member is placed, there is no need for an electric pump, and the structure is Although it is easy to absorb water by penetrating the middle wall and immersing the lower end in the nutrient solution, The member raises the nutrient solution in the liquid storage chamber by capillary action, and the water absorbing member and the middle partition wall The water-retentive sheet covered with the water-absorbing material disperses the nutrient solution absorbed by the water-absorbing member. In addition, the lid member that covers the cultivation tank holds the growth of hair roots. It prevents the nutrient solution from drying out in the culture tank and maintains a humidity of 80% or more, making it easier for cultivation. The growth of elephant plants is significantly promoted and a large harvest is obtained, leading to industrial effects. It's extremely large.
