Native to Eurasia, China produces about 50 species, mostly grassland psammophytic, xerophytic deciduous shrubs, forage green manure plants. Widely distributed in the northwest, Inner Mongolia and other places. It is also distributed in the people's Republic of Mongolia and Siberia of the former Soviet Union.

Caragana microphylla is scattered in the arid steppe community, with a height of 40-70cm, much branched and shrub-like. Caragana korshinskii is tall, 150-300cm high, its bark is golden, and its leaflets are lanceolate or rectangular, which are desert psammophytic and xerophytic shrubs, scattered on mobile sandy or semi-fixed sandy land in desert and semi-desert areas. Caragana intermedia has a lower plant height of 70-250cm, and its bark is yellowish gray, yellowish green or yellowish white, distributed in the sandy land of steppe and desert steppe. Caragana cultivated in production, or Caragana, is generally mixed with Caragana and Caragana. Cold-resistant, drought-resistant, not afraid of sand pressure and wind erosion. It has the function of preventing wind and fixing sand and preventing soil and water loss. It is better to sow in rainy season without soil preparation, strip sowing or on-demand sowing, with a sowing rate of 15-22kg per hectare. After Lignification, it affects its palatability and can be processed into grass powder, which can be mixed with other grass powder to feed livestock. In addition to feeding, it is used as a windbreak and sand-fixing shrub belt or biological fence on desert steppe.
