The invention relates to a method for cultivation of crops in solid phase, air phase is under the solid phase, and water phase is under the air phase. The water and nutrition which the growth of the crops need are extracted from the liquid phase by a thin film (belt) having absorbability and transfusion function as capillary into the solid phase passing through air phase. The crops need not watering for a long time (more than 30 days) and no rotten root occurs by this method. The seawater can be used for planting by placing a molecular sieve (osmosis film) which can block the salinity but let the water molecule get past on water sucking substance at the bottom of solid phase. Thin method is suited for crops and flowers planting on desert, water surface, island, sand'stone land and space upin the air etc. The method can be used commercially.
