| Abstract: |
| The strain of Yumi 2 was used as a material to study the grain yield and water use efficiency of proso mil-
let under different water saving treatments in standstorm area along the Great Wall . The results show that the water saving ways may improve field catchment and water retention, increase soil water content，reduce water consumption amount and water consumption intensity. The grain yield of proso millet with film mulching on ridge and double furrows was largest， reaching 6 927.43 kg/hm2 and increasing by 40% compared to CK，while its water use efficiency was 17.22 kg/ (hm2·mm)，increasing by 60.19%. Film mulching on ridge and double furrowss may improve field catchment and water reten-tion，and increase grain yield and water use efficiency. |
