[Problems to be solved by the device]

 Among the above-mentioned technical documents, the invention of JP-A-1-104120 catches the problem of root rot. However, according to the present invention, a part of the nutrient solution supply passage provided in a part of the plant cultivation medium is used as an air passage, and a part of the plant cultivation medium is always present in the nutrient solution. (The plant cultivation medium is in a wet state.). Therefore, when the roots of the cultivated plant extend to the wet part, a problem of root rot occurs. In addition, since the structure does not form an air passage directly at the root occupying site (position), the intake of air to the root occupying site is not always sufficient, and it adversely affects growth. There are issues such as. On the other hand, in the structure of the present invention, that is, in the structure in which the medium for plant cultivation has a semi-cylindrical shape, a rectangular tube shape, etc., and the nutrient solution supply passage serving as an air passage is opened on the lower surface thereof, the nutrient solution and the lock rule are Since the contact area is not uniform, the capillaries of the rock wool are biased, the nutrient solution cannot be properly supplied to the cultivated plant (cultivated crop), and the uneven growth may occur. There is a problem. Furthermore, since the nutrient solution supply passage is formed to a large extent, a large amount of mineral wool such as rock wool is generated, resulting in waste of resources, and an increase in the cost of the plant cultivation medium. There's a problem.

[0007]

[Means for Solving the Problems]

 Therefore, the present invention is to reliably prevent root rot through sufficient air supply to the roots of cultivated plants through the air intake means provided in rock wool, and to ensure contact between nutrient solution and air. For the purpose of maintaining the nutritional balance of the nutrient solution and evenly supplying the nutrient solution to the cultivated plant through the uniform contact between the nutrient solution having the nutritionally balanced nutrient and rock wool. , Adopted the following configuration.

That is, the growing block having the germination plug (rock wool pot, seed block) of the present invention is a growing block made of mineral cotton such as rock wool, and the growing block and / or At the root occupying site with a germination plug, air intake means with a coarse density distribution, or air intake means consisting of hollows such as through holes and kerfs, or lattice-like through holes and kerfs The air intake means composed of the hollow portion is provided.

[0009]

[Action]

 Next, a system for supplying fresh air to the roots of cultivated plants through the air intake means of the present invention will be explained. First, plants (crops are the same) are cultivated in germination plugs (Fig. 8), and A large number of rows are provided on the cultivation bed, and the nutrient solution is supplied to the cultivation bed by an intermittent method or a dropping method (without limitation). Since this germination plug is provided with an air intake means (it may be possible to provide no air intake means), when the nutrient solution supply is stopped and the germination plug is released to the atmosphere, Air is taken into the germination plug through the air intake means, and the contact with the air avoids the wet state of the germination plug, thereby preventing the germination plug from becoming a root of so-called root rot. It has a structure that eliminates wet conditions.

As described above, when the germination plug is grown to a predetermined size, the germination plug is inserted into the small hole of the growing block (which may be a seedling block), and the growing is performed. The next cultivation is started using the cultivation block and the growing mat and through the dropping method (Fig. 9). Since this growing block is provided with an air intake means, when the supply of the nutrient solution is stopped and the growing block is released into the atmosphere, the growing block is fed through the air intake means. By taking in air into the plant and avoiding over-humidity of the growing block (generally, the root is immersed in water) through contact with air, it becomes the root of so-called root rot. It has a structure that eliminates the over-humidity of the growing block.

As described above, when the growing block is grown to a predetermined size, the growing block is provided with a growing mat (rock fiber, rock wool mat, rock wool bed, or sand and rock wool). There is also a case where a growing mat is placed on top of it.) The next cultivation is carried out by using the growing mat and using the dropping method (Fig. 10). When this growing mat is also provided with air intake means, when the nutrient solution supply is stopped and the growing mat is released into the atmosphere, the air intake means is used to The air is taken into the growing mat, and the contact with the air avoids the over-humidity of the growing mat, and eliminates the cause of the so-called root rot.

By adopting the above-described cultivation method and rock wool mechanism (apparatus), the over-humidity state of the growing block and the growing mat (hereinafter, both are collectively referred to as a growing block, etc.) is maintained. In addition to avoiding, the air taken in by the air intake means can be pushed up to the upper part of the growing block etc. by the nutrient solution so that the air can be supplied to the whole roots in the growing block etc. There is an effect that this nutrient solution can be uniformly supplied to the entire growing block and the like through the contact of the entire lower portion (the entire bottom surface) of the growing block and the like.
