Scope

Scope: This standard specifies the terms and definitions, planting environment, pre-planting preparation, planting process, field management, harvesting, and storage in the cultivation of alfalfa. This standard applies to the cultivation and management of alfalfa. Main technical content: Terms and definitions. The following terms and definitions apply to this standard: 3.1 Fall dormancy of alfalfa is a growth characteristic of alfalfa. In autumn in the northern latitudes, due to reduced sunlight and decreasing temperature, changes occur in the morphological type and production capacity of alfalfa. Under short-day conditions, different types of alfalfa show distinct responses to low temperatures. Southern types are referred to as non-fall dormant (generally in grades 7-9), while northern types are called fall dormant (generally in grades 1-6). 4 Planting environment. Alfalfa is not particularly demanding on soil conditions. It is most suitable for growing in high and dry, flat, well-drained, deep and loose soil with a pH value of 7-8 and a soluble salt content of less than 0.3%. The groundwater level should not be lower than 1m. 5 Pre-planting preparation 5.1 Seed selection and treatment 5.1.1 Variety selection. Choose drought-resistant, salt-resistant, cold-resistant, high-quality and high-yielding varieties with high protein content and fall dormancy grades of 3-5, which have passed national or provincial approval, such as the domestic varieties of the Medicago series; foreign varieties such as Golden Queen, Argonqueen, Pioneer, and WL324. For the Hetao region, Golden Queen, Argonqueen, and the Medicago series are recommended. 5.1.2 Seed treatment. Before sowing, the seeds are cleaned to remove impurities and immature seeds. The purity and germination rate of the seeds should reach more than 85%. They are exposed to sunlight for 2-3 days to break dormancy and improve seedling emergence. For seeds harvested in the same year, they must be exposed to sunlight for
