Wintering management of Astragalus membranaceus typically involves several methods depending on the scale of cultivation. One common approach is to transplant all the plants into a greenhouse for protection during the cold season, which is especially suitable for aquaculture operations. Another method involves setting up a plastic greenhouse over aquaculture ponds, making it ideal for small-scale farmers. However, this method requires constructing a greenhouse, which can be costly. For households in mountainous or rural areas, a simpler and more cost-effective option is to use a cement tank that is easy to manage. Before the water temperature drops below 5°C, it's recommended to add soil to the pond and shape it into a "10" pattern, then compact it slightly to help the Astragalus enter hibernation. The soil depth should exceed 30 cm to provide adequate insulation. When the temperature falls between 0°C and 5°C, the pond should be drained to prevent freezing. This helps harden the mud at the bottom and avoid damage from ice formation. To protect the soil from direct sunlight and reduce moisture evaporation, covering it with a straw curtain is highly recommended. Additionally, it’s important to spray water around the pond before and after noon to maintain proper soil humidity. As temperatures begin to rise in early spring, around 5°C, water can be gradually reintroduced into the pond, and a small amount of feed can be added to support plant growth. Proper monitoring and timely adjustments are essential to ensure the survival and health of the Astragalus membranaceus through the winter season.
