The invention discloses a movable lotus root-cultivating pool as well as a manufacturing method thereof, belonging to a cultivating and breeding system. Piles (13) are fixedly arranged on a foundation of the movable lotus root-cultivating pool. The outer sides of the piles (13) are connected with cloth-connecting clamps (6) through a special tool. The waterproof cloth (1) of cloth-supporting clamps (8) is served as a pool dam. The joint parts (15) of the piles (13), the waterproof cloth (1) and the foundation are provided with connecting mechanisms. A drain valve (17) and a feed valve (18) are arranged in the pool. The invention has the advantages of leaking stoppage, water level regulation, no pollution and reduced cost. The effect can be better if the tilled land and wasteland of paddy fields as well as the ceilings and cement foundations of urban tall buildings are utilized. The method comprises the following steps of laying 15-20 centimetres of soil by utilizing the special tool; transporting up and down in a building; plowing and weeding; ditching;burying lotus roots; and harvesting, wherein water with the height thereof 20 centimetres is introduced in the pool, so that the lotus roots can grow in the shallow soil layer plane in all directions. Thus, the lotus roots can be harvested easily. Especially, the acre yield is increased to 12 kilograms from more than 1 kilogram. The economic benefit is twenty-six thousand per acre each year, which becomes ten times on year-on-year basis. Meanwhile, the movable lotus root-cultivating pool has the advantages of purifying air, regulating air temperature, beautifying cities and the like.
