PROBLEM TO BE SOLVED: To provide a safe cultivation method of strawberry in which a field crop is made not contaminated or infected by saprophyte and pathogenic bacteria without adopting a disinfection process. SOLUTION: In a strawberry cultivation method by a washing farming system, at an artificial controllable environment, when an old bulb is performed by a runner growth to cultivate a strawberry sapling, in an old bulb growing period in which an old bulb is performed with a runner growth to take a runner, a routine cleaning is performed by a frequency of one time within six hours (process ST1), and in a raising seedling period of a new bulb after taking a runner, the routine cleaning is performed by a frequency of one time within four hours to 24 hours (process ST2). When a raised strawberry sapling is transplanted to a medium to cultivate strawberry, a regular washing is done by a frequency of one time within one day to seven days at an initial transplant raising seedling period after transplanting (process ST3), and the routine cleaning is performed by a frequency of one time within seven days to 14 days (process ST4). Hypochlorous acid water is used as a washing liquid at each of processes. COPYRIGHT: (C)2013,JPO&INPIT
