| |
| Abstract: | Mole drainage has been considered as one of the effective measures for water-logging control and the technology of which has widely been used at home and abroad. However, mole irrigation is something new. In regions of sajong black soils in the north catchment basin of Huai River,the author made a feasibility study on the dual-obiective function of mole system for both irrigation and drainage,with proper spacing, depth and other factors included.
