内容記述 | Recently, many paddy fields-(flooded rice fields)-have been rotated from paddy to dry crop farms. In order to control the over-production of rice, about 20 percent of all paddy fields in Japan, are changed temporarily to dry farming without major changes of the geophysical nature of the land. For these multi-use farm lands, many additional miles of drains are needed. Although many miles of drains are installed each year, they are still based on the trial and error system of the past. This report investigates the planning and use of tile drains for these rotational farms. The results of this study are as follows;(1) the designed requirement of drainage is theoretically determined,(2) the criteria of whether or not drains are needed,(3) the calculation of spacing of drains, and (4) the integrated drainage systems installed are pointed out. | |||||
