Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a seedling raising device for supplying water or a culture solution to germinate a large number of plants from seeds and growing the seedlings, or for growing small seedlings until a root pot is formed.

[0002]

[Prior art]

 Conventionally, seedling incubators in which many thick pots of about 5 cm are formed of thick plastic are used. Cultivated soil is put in this pot, seeds or small seedlings are planted, and water is supplied in a shower form from above to grow. In this seedling incubator, the shower water is absorbed by the soil, but the excess water is drained immediately. The water absorbed by the soil is evaporated from the soil surface and dried. Therefore, water must be supplied from above two to four times a day. In order to reduce the number of times of water supply, it is necessary to increase the cultivation volume and increase the water absorption. This has an adverse effect on the plant due to excessive water, and has a problem that the root grows downward, so that it takes time and effort to remove the seedlings at the time of transplanting the plant, and the root shape is easily broken. Furthermore, due to the shower-like water supply, the interior of the house was over-humidified and the working environment was degraded. Conventional seedling raising equipment requires a large amount of cultivation soil and increases costs. In addition, since the pot is about 5 cm deep, it takes a long time to form the root pot.

[0003]

[Problems to be solved by the invention]

 The problem to be solved by the present invention is to solve these problems in the past, and to reduce the time and effort of water supply by automatically supplying water. It is an object of the present invention to provide a practical bottom irrigation seedling that can be formed in a short period of time, can supply an appropriate amount of water, and does not increase the humidity in the house.

[0004]

A plastic seedling pot pallet that is immersed in the tank and formed with many shallow recesses for growing seeds or seedlings is placed on the water supply sheet, and openings are provided on the bottoms of the recesses. Bottom watering and raising seedling device characterized by interposing a water permeable sheet that does not allow the passage of roots between the part and the water supply sheet 2) The water permeable sheet is joined to and integrated with the bottom of the recess, and the water supply sheet is placed above the water surface The bottom-watering seedling raising device according to the above 1), wherein the supporting base to be supported is erected in the water storage tank 3) The bottom-watering seedling raising device according to the above 1) or 2), wherein the depth of the concave portion of the seedling raising pallet is 8 mm or less. 4) Provide a water-supply sheet with water permeability by capillary action above the water surface of the water tank for storing seedling-raising water and culture solution, immerse one end of the water-supply sheet in the liquid in the water tank, and add seeds or seedlings. A plastic seedling pot pallet having a large number of through-holes for growing the seedlings was placed on the water supply sheet, and a water-permeable sheet that did not allow the passage of roots was interposed between the opening below the hole and the water supply sheet. 5) A watering and raising seedling raising apparatus according to the above item 4), wherein the water-permeable sheet is joined to and integrated with the bottom surface of the seedling growing pot pallet, and a support base for supporting the water supply sheet above the water surface is erected in the water storage tank. Bottom watering and raising equipment 6) The bottom watering and raising equipment according to 4) or 5) above, wherein the depth of the hole of the seedling raising pallet is 8 mm or less.

[0005]

[Action]

 In this invention, the water and culture solution for raising seedlings in the water storage tank rises up the water supply sheet by capillary action from the soaked portion, and through the water-permeable sheet, from the opening of the seedling raising pot pallet or the opening of the hole or the recess. It moves into the hole and is cultivated in the recess or hole, or water is directly supplied to the root. In this way, the plant is supplied with a necessary amount of water, there is no need to supply excess water, and there is no need to waste an expensive culture solution containing the growing nutrients of the plant. Also, the amount evaporated to the atmosphere can be greatly reduced, and the inside of the house does not become humid. The permeable sheet also prevents the roots from growing downward, grows horizontally, and forms disc-shaped root pots in shallow recesses. Particularly, when the depth of the concave portion is 8 mm or less, a horizontally expanded root pot can be effectively generated.

[0006]

[Embodiment of the invention]

 It is sufficient that the water tank of the present invention has a water depth of about 20 mm. The water tank may be a plastic container having a height of about 30 mm or a water channel having a water depth of about 20 mm. The water supply sheet is a thick woven or fiber cloth, and the water permeable sheet can be a thin woven sheet made of synthetic resin such as nylon or a fine mesh sheet. The water-permeable sheet should be adhered to the bottom of the recess or the bottom of the hole in the seedling pot pallet, and the opening should be completely sealed to prevent the root from stretching downward. The seedling raising pot pallet having a large number of recesses can be easily manufactured by a manufacturing method in which a single sheet of hard plastic having a large number of openings is formed by integral molding to form the recesses. The size of the concave portion may be about 30 mm × 30 mm and a depth of about 5 mm. The seedling raising pallet in which a number of holes are formed can be manufactured at a low cost by manufacturing the method by drilling holes in a foamed resin board having a thickness of 5 to 10 mm.
