The baiba grass of the Mongolian steppe is not suitable for growing crops.

Most of the regions of Mongolia belong to the continental temperate steppe climate, with obvious seasonal changes, long winters, and frequent heavy snowstorms. The summer is short, and the temperature difference between day and night is large; Spring and autumn are short. It is the most powerful Mongolian high pressure center in the world and one of the sources of winter "cold waves" in the Asian monsoon climate zone.

The frost-free period is about 90-110 days from June to September. Precipitation is very small, with an average annual precipitation of about 120-250 mm, 70% concentrated in July-August; The northwestern region has a temperate coniferous forest climate, with many peaks covered with snow all year round.

Extended Materials. The temperature range of the grassland in Inner Mongolia is significant, and the temperature range in most areas is generally 65 -85, and the diurnal temperature range is 13 -16 per year, which is the largest temperature range in China, which is very conducive to the storage of sugar and the condensation of substances in grassland plants.

The large temperature difference between day and night, high altitude and cold climate of the Inner Mongolian prairie minimizes the epidemic of infectious diseases in livestock. Pure pastoral areas generally have more cold weather, and some pastoral areas have begun to snow in October, such as Hulunbuir Hailar in Inner Mongolia.
