The frost-free growing season within the Amur River basin varies significantly based on latitude and proximity to the interior:

  • Southern regions: Near Harbin, the frost-free period lasts for approximately 130 days.1
  • Northern and inland regions: The duration of the frost-free period decreases to about 90 days.1

This variation is largely influenced by the basin's northern location and the impact of monsoon winds that characterize the climate of East Asia.1
