Scope: This standard specifies the terms and definitions, production area, technical requirements, test methods, inspection rules, labeling, packaging, transportation, and storage for the geographical indication product, Huining Youshi Wheat (Huining County People's Government Document No. 10 [2017]), which was approved by the former State Administration for Industry and Commerce Trademark Office for registration in accordance with the Trademark Law of the People's Republic of China and other laws and regulations (registration number: 23307868). Main technical content: The product requires strong adaptability to the environment, high yield potential, good quality, and resistance to lodging. Currently, suitable varieties include Dingyoushi No. 5, Dingyoushi No. 6, Dingyoushi No. 7, and Baiyoushi No. 18. Site conditions: Youshi wheat prefers cool, humid, and sunny environments and is intolerant of high temperatures. Seeds can complete the vernalization stage and germinate slowly at 2-3°C, and the optimum growth temperature for emergence to jointing is around 15°C. During the booting stage, a temperature of around 20°C is required. Youshi wheat is a long-day crop, requiring 16 hours of sunlight daily with strong illumination. Insufficient light during the four-leaf differentiation period (about 12 days before heading) may lead to poor pollen development and severe empty grain. The growing area should be in cool and humid regions. Huining Youshi wheat is located in the temperate monsoon climate zone of the Longxi Loess Plateau, with an altitude of 1,600-2,100 meters and an annual rainfall of 180-450 mm. Soil requirements: The soil should be loose, fertile, with an organic matter content of over 1% and a total nitrogen content of 0.15-0.18%. The phosphorus content should be 8-18 ppm, and the fertility should be moderate or above. Water requirements: The irrigation water must meet the second-level standards of GB 15618, the environmental and air quality must meet the fir
