<p>PROBLEM TO BE SOLVED: To improve workability at the time of supplying to a pot with a pot automatic sowing machine by adding suitable specific gravity and flowability for pot raising seedling to a rice hull charcoal impregnated into unhulled rice vinegar, and to provide a suitable PH control liquid for a soil for horticulture used for a paddy-rice raising-seedling.SOLUTION: By mixing the rice hull charcoal impregnated into unhulled rice vinegar with a mixture consisting of calcium granular fertilizer and phosphorous acid granular fertilizer, while adding the suitable specific gravity and the non-blocking at the time of supplying to a seedling raising pot with an automatic sowing machine, a root zone restriction material composition is considered to have a nutrient for growth of a seedling. As PH control liquid, the mixture of the unhulled rice vinegar of PH4 and the chicken-droppings combustion ash aqueous solution of PH11.5 is used. The root zone restriction material composition 5 is arranged to the bottom of the seedling raising pot 1, and a moulding 4 whose PHs is adjusted with PH control liquid, a soil cover 2 and pre-germinated unhulled rice 3 are arranged in order.</p> |
