胡枝子属植物主要分布于东北,西北、华中及内蒙古等地的干旱半干旱草原区内的山坡草地,丘陵及石质山坡等。在东北松嫩草原上主要分布有兴安胡枝子(称达呼里胡枝子)和细叶胡枝子,(又称铁扫帚,尖叶铁扫帚),根据我们在松嫩草场几年来的野外调查统计,裁培试验及营养价值分析证明,兴安胡枝子和细叶胡枝子具有耐寒、耐旱和良好的防风固沙功能,其抗逆性强、营养价值丰富,是干旱半干旱草原植物饲料中重要的蛋白饲料来 Lespedeza is mainly distributed in hillside grasslands, hills and stony slopes in the arid and semi-arid steppe regions of Northeast, Northwest, Central China and Inner Mongolia. In the northeast Songnen grasslands are mainly distributed in Leshan Lespedeza (Lesser vicuña) and Lespedeza bicolor (also known as the iron broom, pointed leaf broom), according to our past years in the Songnen pasture field survey statistics , Cutting experiment and nutritional value analysis showed that Lespedeza and Lespedeza obtusifolia had the functions of cold tolerance, drought tolerance and good windbreak and sand fixation, and their strong resistance and rich nutritional value were important in plant feed of arid and semi-arid steppe Protein feed comes
