Abstract
We selected for study the eastern block of the Luohui Irrigation District, which is called the Luodong block. The research area is in the southeast part of the Loess Plateau, which is in a semiarid climate zone. Furrow and border irrigation in the block have been practiced over about 32,000 ha of irrigated area, where crops such as cotton, wheat and fruit are predominant. Based on onsite experiments in the research area, we classify salinization processes, reveal causes of farmland salinization, and propose countermeasures to prevent these phenomena. Lowering groundwater level by improving drainage systems, controlling dumped saline soil, and managing the use of saline irrigation water are recommended.
