The present invention relates to a kind of for constructing the ridge rice field between boundary block. The present invention is configured as continuously fixed boundary block and is connected to each other, and by crest line rice field between fixed device transfer hole, boundary and boundary paddy field and outside between a kind of rice field, the ridge between construction rice field can be facilitated in this way, and shortening construction period. Because water level drainage unit, which executes drain operation, is equipped with boundary block by selective rotation side, draining selectively execute in rice field adjacent to rice field subregion, pass through the boundary block and only adjusting to allow the rice field of water level by the boundary block to external neighbouring rice field subregion. The device of connection valve and spraying spraying chemicals is mounted across the boundary block that the side wall in hole is pricked in top installation if fertilizer or insecticide side are provided with longitudinal fluid supply line so that fertilizer or insecticide smooth can spray to rice field subregion by the boundary block. Since the side of connection valve is provided with the installation of longitudinal flow supply pipe by the side wall upper part boundary block in installation bundle hole, sprinkler is selectively connected to connection valve and promotes operation watering crop. Therefore, the boundary block, wherein being equipped with connection valve applied to rice field, field and vinyl house, therefore, sprinkler operation is used for the rice field of plant culture, field and vinyl house, can be easy to carry out.Copyright KIPO 2017
