The company is working to reduce production costs and improve its product varieties to supply higher quality products.

[0004]

[Problems to be solved by the invention]

 However, farmers who germinate and take root on their own (hereinafter referred to as self-produced farmers) place seeded trays and grafted seedlings in a vinyl house, and hang or remove them on top of them. The temperature and humidity of the soil and air inside the greenhouse are kept constant. However, in such a method, the fluctuation range of the temperature and humidity becomes large, so that the germination rate and the rate at which the graft is normally established are reduced. In particular, in the summer when the heat during the day is severe, and in the winter when the cold at night is severe, the survival rate is about 75%, the germination rate is as low as about 50%, and the production efficiency is extremely low. There's a problem. On the other hand, if a germination and germination device such as that owned by the JA Nursing Center is used, the germination and germination ratio can always be over 90%, but such a device is very large and requires high installation costs. As a result, self-produced farms cannot be owned by individuals, and even if they are able to do so, the production capacity of the equipment is too large for the number of seedlings grown by the self-produced farmers, and waste is increased. There's a problem.

[0005] In view of such circumstances, the present invention provides a plant cultivation system that can increase the rate of germination and germination, can easily adjust the temperature, has a low installation cost, and can be owned by a self-produced farmer. The purpose is to provide.
