PURPOSE:To culture plants over a year without using an agricultural chemical by applying the physical actions of an energy-saved heat generator to perform soil disinfection, seedling growth temperature control, insect pest removal, seedling growth stimulation, etc. CONSTITUTION:A heat-insulating depressed box is set in a wide green house, and a carbon surface heat generator 2 for irradiating far IR rays and a carbon electric field-generating sheet 5 for producing a (-) potential of 1000-8000V are buried in the box. Resin meshes 6 are further buried in the box, and are covered with soil 7 mixed with fertilizers and manures. As physical actions, far IR rays irradiated from the carbon surface heat generator 2 give a soil- sterilizing effect by the control of the generated heat and also applied to the growth temperature of plants. Since set at such a position that (-) ions are generated in all of the plants, the carbon electric field-generating sheet 5 produces a strong electric potential in air, has an effect to lose insect pests their visual senses, and stimulates the circulation of nutrients in the plants. |
