Increasing crop yield per unit area and water use efficiency (WUE) has been a key problem of dryland agriculture on the Loess Plateau. Since the
film mulching technology was introduced into China’s agricultural production
in the 1980s, it has undergone several updates. At present, on groove ridge
tillage of plastic film mulching cultivation mode gradually develop into a
rainfed agricultural region on the loess plateau of farming technology, its
traditions in farming technology and experience, on the basis of combined with
conservation tillage technology, greatly expand the application and promotion
of space, effectively solve the problem of thetime the crops drought, It provides
strong support for stable and high yield of grain in this area. This paper
summarizes the development of furrow and ridge film mulching technique in
upland area of loess Plateau, and explains the reasons for high yield of furrow
and ridge film mulching technique from aspects of moisture, temperature and
light. At last, the negative effects of furrow and ridge mulching were analyzed
in order to continuously improve the furrow and ridge mulching system and
provide reference for future agricultural technology innovation in arid areas.
