| Abstract: |
| In order to provide a scientific basis for irrigation of forage oats （Avena spp.） in the region of Darhan Maoming’an Union Banner（hereinafter referred to as Damao Banner）, Inner Mongolia, The Penman-Monteith formula method recommended by the Food and Agriculture Organization of the United Nations (FAO) was used to analyze meteorological data for 30 years (1991 to 2020), and research was conducted on the water demand pattern of forage oats and irrigation quotas for the Damao Banner area in Inner Mongolia. The water requirements of forage oats in Damao Banner, Inner Mongolia, were 497 mm, 422 mm, and 919 mm for the 1st, 2nd, and full production periods, respectively. The water demand intensities were 5.5 mm/d, 4.1 mm/d and 4.8 mm/d, respectively. Irrigation water requirements were 435 mm, 292 mm and 728 mm, respectively. Irrigation quotas were 512 mm, 344 mm and 857 mm, respectively. |
