Key Technical Points and Methods for Direct Seeding Afforestation of Caragana microphylla
Caragana microphylla, a shrub or small tree of the Fabaceae (Papilionaceae) family, is extremely light-demanding, resistant to severe cold and intense heat, highly tolerant of drought and barren soil, and highly adaptable. It is an excellent tree species for sand fixation and soil conservation in deserts and grasslands. Its tender branches and fresh leaves are good fodder for livestock, especially sheep, and it is also a good firewood plantation species. Seeds can be collected for direct seeding afforestation. The seeds mature from July to August; harvest when the pods are hard and yellow-brown. The time from fruit maturity to pod dehiscence is very short, so harvest as they ripen. Dry the harvested pods in the sun and remove the pod shells and debris. Good seeds are yellow-green or cream-yellow and glossy.
