云南胶园耐荫豆科绿肥资源调查与评价

Investigation and Evaluation of Shade-tolerance Leguminous Plant Resources in Yunnan Rubber Plantation

本文系统调查了云南主要植胶区开割胶园中豆科绿肥资源种类、地理分布、结瘤情况等,并对绿肥资源现状与结瘤特征进行了评价。研究结果表明,云南胶园现有耐荫豆科绿肥22属42种。绿肥虽然分布广泛,但植株个体数量少;生活型以草本、藤本、亚灌木为主;属中种类少;基本未被开发利用。所调查豆科绿肥结瘤率达88.2%,根瘤大且数量多,形状以球形、椭球形为主,颜色多为粉红、红色。

The plant species,their geographic distribution and nodulation of leguminous green manure plant in Yunnan tapped rubber plantation were investigated and evaluated in this paper. The results showed that there were 22 genera and 42 species leguminous plants growing under rubber tree canopy in Yunnan Province. These plants were widely distributed with low plant population. Herbage,vine and bush were main growth types. There were a few species in each genera. The exploitment of these resources were limited. The nodulation rate of these plants was 88.2%. The large,round or oval shape,and pink or red color of root nodules were observed and recorded.
