GROWTH OF YOUNG SEEDLING OF PADDY RICE PLANT AND MATERIAL THEREOF

摘要

PURPOSE:To avoid excessive obstacle of fertilizer component and shortage of fertilizer in growth of young seedling of paddy rice plant using an inorganic fiber mat as a sowing bed, making soil cover part not to be directly brought into contact with root part retain necessary fertilizer component. CONSTITUTION:After seeding is carried out in a sowing bed consisting of an inorganic fiber mat containing no fertilizer component, the sowing bed is covered with soil containing 0.05-0.3wt.% nitrogen, 0.05-0.3wt.% phosphoric acid and 0.05-0.3wt.% potassium as fertilizer components. A material having the following structure is preferable as a material for growing young seedling of paddy rice plant. Namely, the sowing bed is a rock wool mat containing no fertilizer component and the soil for cover is granulated artificial soil containing 0.05-0.3wt.% nitrogen, 0.05-0.3wt.% phosphoric acid and 0.05-0.3wt.% potassium as the fertilizer components.
