摘　　要：糙毛假地豆(Desmodium heterocarpum DC var. strigosum Van Meeuwen)是多年生豆科草本植物,在广东省郁南县自然条件下零星分布,未形成大面积种群。研究表明,该植物适应光照能力强,适于荫蔽林下生长;其叶片冬季具有较高的叶绿素含量及一定的净光合能力,且根部仍具有固N活性根瘤;根系发达,地上部分形成密实覆盖层,与其他杂草竞争能力强,具有多种生态功能,在开发利用当地生物资源中具有较高的应用价值。Desmodium heterocarpum DC var. strigosum Van Meeuwen is a perennial herb which is rare in Yunan County, Guangdong Province. It has high adaptability to sunshine which enables it to grow very well under shady conditions. Even in winter its leaves have relative high contents of chlorophyll and can sustain certain net photosynthetic rate. It also has an extensive root systems and dense canopy and its root bears some nodules which can fix atmosphere nitrogen. Those characters enable it to compete with weeds. It has multi-ecological functions. Then this herb has high application value in the utilization of local biore-sources.
