摘  要:
The improvement of low-medium yielding farmlands is a basic engineering to promote the development of agriculture. It has important pole on meliorating the agriculture foundation condition, promoting agricultural comprehensive productive ability, increasing the effective supply of major agricultural products and fanners' and income, etc. This improvement is also a comprehensive system engineering, which involves agronomy, engineering, hydrology, pedology, economics, ecology, etc. There have abundant research results on improving low-medium yielding farmland. Based on a lot of previous work, the paper main introduces the concepts, type, cause and technology on low-medium yielding farmland, and discusses the existing problems of current works and future research direction.
