摘　　要：为充分利用热带人工林下弱光资源,在云南开割橡胶园,通过定量的叶片生理和结构指标聚类分析,同时结合定性的引种试验,综合评价了8种豆科覆盖绿肥的耐荫性。8种绿肥按其耐荫性强弱可划为3类,第1类,耐荫性强的绿肥,假地豆、硬毛宿苞豆、大叶山蚂蝗、大叶拿身草,长势好且能完成其生活史。第2类,耐荫性中等的绿肥,距瓣豆、羽叶决明,长势好或能完成其生活史。第3类,耐荫性弱的绿肥,十一叶木蓝、毛蔓豆,长势差且未能完成其生活史。In order to make full use of low-light resources under tropical plantation,shade-tolerance of eight leguminous green manure mulching was evaluated comprehensively in Yunnan tapped rubber plantation,through quantitative leaves physiological,structural indicators of cluster analysis,combined with qualitative introduction tests.Shade-tolerance of thoseplants can be classified as strong or weak in three categories,among which type 1:highly shade-tolerance green manure,like Desmodium heterocarpon(L.)DC.,D.laxiflorum DC.,D.gangeticum(L.)DC.and Shuteria hirsuta Baker,grow well and can finish its life cycle.Type 2:medium shade-tolerance green manure,Centrosema pubescens Benth and Chamaecradta nictitans Senecio,also grow well and probably can finish its life cycle.Type 3:weak shade-tolerance green manure,Indigofera spicata Forsk.and Calopogonium mucunoides Desv.,grow poorly and failure to complete its life cycle.
