PURPOSE:To culture vegetables in the same quality and yield as those by a circulation type water culture method by dissolving the No.1 and No.2 matures in the form of additional manure solutions in a culture solution in a thin film culture method and specifying the additional manure solution concentration of the No.1 manure and its amount. CONSTITUTION:The No.1 and No.2 manures in the form of additional manure solutions are dissolved in a culture solution in a thin film water culture method, and the additional manure concentration of the No.1 manure is controlled to approximately 1.8kg manure/10 liter of the solution, the concentration being consumed after approximately a week or 10 days. The No.1 manure contains potassium nitrate, magnesium sulfate (heptahydrate) and ammonium dihydrogernphosphate or potassium dihydrogenphosphate, and the No.2 manure contains calcium nitrate (tetrahydrate). |
