FORCING CULTURE SYSTEM FOR JAPANESE HORSERADISH IN GREENHOUSE

摘要

PPROBLEM TO BE SOLVED: To provide a forcing culture system for Japanese horseradish in a greenhouse by which the period required for cultivating Japanese horseradish can be shortened; irrigation water resource is not limited to spring water or mountain runoff water; not so large quantity of water is necessarily secured; the Japanese horseradish is prevented from disease damage such as soft rot or inking as much as possible, and cultivation management work is reduced and rationalized so as to enable power saving. PSOLUTION: The forcing culture system for Japanese horseradish in a greenhouse is provided: with air- and water-permeable ridges formed by piling culture soil composed of coarse fragment material in an appropriate thickness on the rooftop of the greenhouse; a watering pipe through which cultivation water is supplied toward the culture soil from above; and a pump supplying water under pressure. In the system, the pump is connected to the watering pipe to supply culture water to the culture medium through the watering pipe; the water is collected or drained to or from the blind ditch by gravitational force during cultivating Japanese horseradish, and meanwhile, the pump is connected to the blind ditch to introduce pressure water for washing the culture medium to the culture medium from the blind ditch, and the culture medium is washed via the pressure of the pressure water to force the Japanese horseradish in the greenhouse.
