<p>[PROBLEMS] To provide a soil culture method capable of culturing various plants (field crops) at low cost without agricultural chemicals by using a simplified facility. [MEANS FOR SOLVING PROBLEMS] In this chemical-free soil culture method, a framework for forming a space for culturing is manufactured on the ground, the outside of the framework is covered by a near ultraviolet cutting type film or sheet to form an outer film, and an insect-proof net is installed on the inside of the framework to form an inner film. A film or a sheet (hereafter, referred to as a waterproof sheet) preventing underground water from being oozed up in an area wider than the width of the framework is laid on the underside of a culture medium, and a mechanism (hereafter, referred to as a water drain mechanism) for rapidly draining rain water fallen on the surface of the outer film to the outside of a field is installed on the outside of the framework on the waterproof sheet. Also, a pipe or a tube for both irrigation, fertilizing, and ventilation is buried in the culture medium.</p> |
