摘　　要：热区(橡胶)林下套种模式具备珠芽魔芋所需的高温遮阴环境,为珠芽魔芋多苗接力生长提供10个月超长生长期,大幅增加叶面积指数,改变花魔芋单叶低产原有的模式,种植周期由3 a缩至1-2 a,显著提高生物产量并使其成为高产作物,提高林地产出效益。以胶树落叶为覆盖物可起保墒压草及增加有机质,利于疏松土壤。采用"挖大留小"就地越冬及叶面球茎自然滚落方式可实现珠芽魔芋低成本种植。The plantation environment suitable for A. bulbifer group, all of which with epiphyllar bulbils at the top center of the rachis and along the three main rachises under warming shading surroundings of rubber tree are the main problems solved in this paper. The corm bulking rate increases sharply from its multi- relay seedlings releasing taking about 10- month growing period, leading to sharp increase of leaf area in shady areas of tropical regions. Fallen leaves as mulches from rubber tree retaining soil moisture, suppressing weeds, and supplying additional nutrients to plants. Height chemical inhibitors used to control the plant overgrowing in deep shady areas. The baby corms unharvested and the falling mature bulbils as natural propagation materials after large corm collected for no fear of winter chilling injury. The plantation period for processing corm shorten from 3 years to 1-2 years.
