摘　　要：为评价地不容在热带橡胶林下的间作发展潜力,在不同光照条件的橡胶园中开展了海南地不容、小叶地不容的间作试种研究。初步结果表明,在粗放的间作管理条件下,两者在南北行向的全周期间作模式胶园内生长良好并有较高的块根产量潜力,但在全自然光照的旷地种植会因光照过强而生长不良甚至植株死亡,而在郁闭度较高的常规橡胶林下则因光照不足生长缓慢且产量低。因此,地不容可作为中低郁闭度橡胶园的备选间作物。同时,本研究对其胶园间作技术进行初步总结,以供研究及生产者参考。In order to evaluate the intercropping potential of Stephania Epigaea Lo in rubber plantations,intercropping trial studies of Stephania Hainanensis H.S.Lo et Y.Tsoong and Stephania Succifera H.S.Lo et Y.Tsoong were carried out in different rubber plantations under different light conditions.Preliminary results showed that under extensive intercropping management condition,both of them grew well and showed high root yield potentials in southnorth direction rubber plantations of complete period intercropping pattern.When they were planted in the open land with full natural light,it would cause poor growth or even plant death due to excessive light.When they were planted under the conventional rubber plantations with high canopy density,the growth was slow and the yield was low due to insufficient light.Therefore,we considered that Stephania Epigaea Lo should be used as an alternative intercrop in rubber plantations with middle and low canopy density,and then made a preliminary summary of the rubber intercropping technology.It can be referenced by researchers and producers.
