The results indicated that the indigenous mulberry, Morusnigriformis Koidzumiand M. australis Poiret, had a good adaptability with tolerance to drought and shade in rubber plantations, and produced a yield of fresh branches and leaves in the three rubber plantations 80.0%, 72.2% and 38.2% of those under natural conditions. The microclimate in the rubber plantations was improved after the mulberry was intercropped, and the net photosynthesis and light use efficiency were enhanced simultaneously, which promoted the growth of rubber tree, especially the immature tree. Water and fertilizer were supplied during the intercropping, or the soil fertility would have been declined because nutrition was moved out of soil with the products harvested. The mulberry had a good ecological service function after intercropped in the rubber plantations. However, its service function tended to decrease with the age of the rubber tree. The total values of its six kinds of functions, including production of raw materials, storage of water resource, soil conservancy, carbon dioxide fixation and oxygen production, were 53284.43 RMB/hm2·a(3a rubber plantation), 45062.46 RMB/hm2·a (6a rubber plantation) and 16464.23 RMB/hm2·a (25a rubber plantation) respectively.
结果表明：(1)鸡桑和海南本土桑种唐鬼桑在胶园中具有较好的适应性，较强的抗旱性和适度的耐荫性，在3个年龄段胶园中的产量分别为纯桑林的80.0%、72.2%和38.2%；(2)间作桑树可改善胶园生态系统小环境，使胶树的光合效率与光能利用率均有所提高，从而有利于胶树的茎粗生长遥但生产中需要加强水肥管理，否则会因收获物带走养分而造成土壤肥力下降；(3)胶园间作桑树具有较好的生态服务功能，但随着胶园年龄的增加，其服务功能价值呈逐渐减少趋势遥间作在3、6、25龄胶园中的桑树，在原材料供应、涵养水源、保护土壤、吸收固定CO2、释放O2、净化环境等6大功能的总价值分别为53284.43、45062.46和16464.23元/hm2·a。
