| Research Abstract |
The purpose of this study is to clarify how to construct of the saving water system and to improve of rice paddy field lot environment applying a winter puddling and direct seeding culture on well-drained rice paddy field. As a result, it was clarified that 20~30 percent of water was saved and irrigation water and soil temperature were stabilized and water environment was preserved applying the deep ponding and non-ponding release irrigation systems. Furthermore, it was clarified that the functions of effective rainfall and storage water were increased.
