The temperature in Yanggao county often falls to as low as -20 Celsius, and in the past farmers concentrated on planting crops that were low-value but resistant to freezing weather conditions. Since 2017, the team led by professor Li Lingzhi from Shanxi Agricultural University has promoted special tomato cultivation techniques suited to cold and alpine regions in Yanggao county.

The introduction of technologies and equipment involving heat preservation, sterilization, and artificial lighting has helped provide ideal conditions to grow high-quality tomatoes. Standardized packaging, mature e-commerce platforms and a professional logistics system have made the product easier to transport across the country. And upgrades to agricultural technology have further helped local farmers increase their incomes. [Photo/Xinhua]
