Description

Background field

Necessary conditions for conducting hydroponic cultivation of this solid medium bottom are lighting instead of sunlight, water, temperature (temperature), and a culture soil having a liquid phase suitable for the cultivation environment in the growing area. It is possible to cultivate many varieties regardless of the season by controlling etc. Hydroponics has made it possible to cultivate vegetables, but it is necessary to cultivate cereals, potatoes, fruits, and root vegetables that can save people from hunger. If it is cultivated in an appropriate cultivation environment, cereals, potatoes, fruits and root vegetables can be cultivated.

Vegetables can be cultivated in hydroponics plant factories, and hygienic vegetable cultivation is now possible, but only vegetables are produced, and it is difficult to grow nutritious grains, potatoes, fruits and root vegetables, but solid Cultivation by changing the liquid phase in which the culture medium is in an appropriate soil environment enables a plant factory for grains, potatoes, fruits and root vegetables that can save people from hunger.

The present invention is water management, which is currently carried out in hydroponics, is the management of light by lighting, and in addition to seasonal temperature management, a liquid-phase culture soil suitable for growth is provided. By using it, it is possible to cultivate any plant, water is stored in a tank placed under the cultivation container, and a water absorption string with good water absorption is placed on the bottom of the cultivation container containing culture soil with a liquid phase suitable for cultivation. After fixing, the tank water is sucked up by bottom irrigation, and the culture soil is sucked up and cultivated. At present, it has been confirmed that in the cultivation of flowers and trees, water can be stored in a small container and water and LED lighting can be used to cultivate in 70% red corn soil and 30% humus soil using a combination of aircon. However, there was no problem with flowers and trees in the culture soil of 70% akadama soil and 30% humus soil, but the fruits did not grow with root vegetables and fruits. Water was frequently irrigated, but no fresh fruit was obtained even in the cultivation of eggplant. For this reason, the cultivation experiment of fruits and vegetables was carried out in the culture soil which raises the liquid phase of black soil, red soil 70%, and humus 30% currently used for local planting. This soil is not impossible because it can be cultivated by natural land planting. However, will the fruit grow if grown in high liquid-phase culture soil? The challenge is to increase the irrigation of water like rain once every 10 days.

Means for Solving the Invention

In order to carry out hydroponic cultivation of vegetables etc., vegetables have succeeded by providing light management instead of sunlight, temperature management with air conditioners and storing water. The above cultivation conditions are the same for the solid culture medium hydroponics, but a suitable culture soil for cultivation of flowers and trees is mixed with 70% red crust and 30% humus, 30% liquid phase, 30 vapor phase. In order to prevent a decrease in the liquid phase of the cultivated soil, which tends to dry, so that it can be cultivated in about 1% culture soil and periodically return to the saturated liquid phase state, irrigation is necessary for the cultured soil once every 10 days. Tree cultivation was successful. However, for cereals, potatoes, root vegetables and fruits, the use of red jade soil for the cultivation of land planting resulted in a lower liquid phase of the cultured soil, so the fruit did not grow. However, cereals, potatoes, root vegetables and fruits are currently cultivated in many areas. 70% of black soil and red soil and 30% of humus soil are stored in tanks, and the soil is periodically saturated. To return, the culture soil is irrigated once every 10 days to prevent the liquid phase of the culture soil that tends to dry. In addition, when irrigated and cultivated, the bottom of the cultivation container is immersed in a tank placed underneath, becoming saturated liquid phase or more and root rot, so a tank is provided with a drain hole so as not to store more than a certain amount of water. Flow outside so that does not accumulate. In addition, a large tank that can store a large amount of water for long-term labor-saving cultivation should be used to prevent the water stored for a long time from being spoiled by light. For cereals, potatoes, root vegetables, and fruits, if the water content of the culture soil is low, it will not actually increase, so in order to increase the liquid phase, the water absorption string is thickened, the water absorption string head is enlarged, and the water storage capacity of the tank is increased. Growth is improved by irrigation once every 10 days.

Effect of the invention

With this solid medium bottom irrigation cultivation system, water is stored in a large tank for labor-saving cultivation, but the bottom of the cultivation container is structured so that it does not immerse in the tank, so air can escape from the bottom to the surface, providing good ventilation In the cultivation of the flowers and trees, good cultivation was achieved with 70% red crust and 30% humus. In addition, since the liquid phase of the culture soil is periodically saturated, if the soil is irrigated about once every 10 days indoors, the culture soil can always be satisfactorily close to the saturated liquid phase. In the case of cereals, potatoes, root vegetables and fruits, culture soil with too good ventilation, such as red crust, has poor moisture retention, and the fruit does not grow, so the liquid phase is raised with culture soil of 70% red soil, black soil, and 30% humus soil. In order to increase the amount of water to be sucked up, the water-absorbing string is set to about 2 cm and the head of the water-absorbing string is enlarged. In addition, with a water absorption string shaped to prevent evaporation, if the head liquid phase at a suction distance of 0 cm is 100%, about 90% of water is sucked up even at 15 cm suction, and the liquid phase of the head of the water absorption string from the culture soil It is possible to cultivate by moving water to the culture soil because it is high, and by this method, it is cultivated as a plant factory that grows indoors regardless of the weather or season, so that it can be used for cereals, potatoes, root vegetables, etc. Fruit can be produced and added to fertilizer to grow it. Mass production is possible, and it is a way to save people suffering from hunger and famine from around the world. ,.

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front perspective view of an embodiment of the present invention, in which a tank is formed into a long box shape with concrete, and three water absorbing strings are fixed to a C water absorbing string fixing hole on the bottom of one cultivation container having a D water draining hole. Draw up the water and drop the excess water down from the bottom drain hole of the D cultivation container. The water absorption cord body of the B water absorption string is formed in a cylindrical shape with a diameter of about 2 cm as shown in FIG. 2 inside the E Katou tube to prevent evaporation. Fix the front end of the body part orthogonally to the center of the piece. 1 C water supply string fixing hole at the bottom of 1 cultivation container is about 1 per 10 cm square area, and the number is increased in proportion to the size of the bottom, but 2 culture soil put into 1 cultivation container is about 50 cm deep, cereals, Plants that grow fruits such as moss, root vegetables and fruits use 70% black and red soil and 30% humus.
