| Abstract: | Three-year continuos test and production practice in northShaanxi proved that yield of film-covered corn in terraced land increased 19.4%～58.3% and WUE increased 23.8% compared with that by routine cultivation techniques; film covering and the correspondent techniques are key measures to achieve high and steady production of crops in new-built terrace and to ensure safety of local food supplies. It is also an important base for achieving the strategical goal of reducing cultivated land to plant more forest and grass. |
