Site conditions: Huining Mung Beans grow in semi-arid and cool climates, with some tolerance to early spring frosts. During the growing season, excessive humidity and rainfall can lead to weak vegetative growth and poor yields. Drought and high temperatures during the flowering and pod expansion periods can also reduce yields. Mung beans are not particularly demanding on soil texture, and can grow in a variety of soils, tolerating poor soils. The pH range for optimal growth is 4.5–8.2. However, the best soils are deep, well-structured, phosphorus- and potassium-rich, with neutral or slightly alkaline pH, good water and nutrient retention, and good drainage. Huining County has a temperate monsoon climate and belongs to the Lanzhou Loess Plateau hilly and gully region, with an average altitude of 2,025 meters, an average temperature of 6–9°C, and annual rainfall between 180–450 mm.
