　　   Planting Conditions

　　　　    Baicheng City is a major mung bean production area in Jilin Province and even in China, with a long history of cultivation. Located in the heart of the Songnen Plain and the eastern part of the Horqin Grassland, the soil is mostly Quaternary alluvium from the Tao'er River, with surface layers consisting of chestnut calcareous soil and sandy loam, offering good permeability. The terrain is flat, with soil organic matter content ≥1.5%, total nitrogen content between 0.12% and 0.22%, total phosphorus content ≥0.20%, total potassium content ≥2.5%, and soil pH between 7.0 and 8.2—conditions particularly suitable for the production and propagation of mung beans. The region enjoys abundant light and heat resources, with a frost-free period of 125–140 days, 2,960 hours of sunshine annually, and effective accumulated temperature ≥10°C reaching 2,900–3,100°C. The temperature difference between day and night in August and September reaches 14–15°C, which aids in the accumulation of nutrients in crops and improves the quality of mung beans. Especially the dry climate in autumn is more conducive to the drying and coloring of mung beans, enhancing their quality. The mung beans produced in Baicheng are large, full, bright green, free of mixed colors and pollution, and have high protein content, enjoying high recognition in both domestic and international markets. The city’s Taonan City has earned the reputation of "China's Hometown of Mung Beans" for producing high-quality, high-yield mung beans.
