摘要
林药间作模式是现代生态农业的一种创新实践,科学规划药用植物与橡胶林的生长周期协同性,可最大化挖掘橡胶林林下空间的复合生产潜力,实现林下资源的高效利用。为进一步探究林药间作的标准化栽培体系,通过在橡胶林林下探索研究积雪草栽培关键技术,提出一套集园地选择、品种培育、定植规范、田间管理及采收处理于一体的栽培模式,且经过实践发现,在4龄南北行向胶园林下间作积雪草,平均收获积雪草干重可达22.35g/m^(2),较大棚种植(18.75g/m^(2))和裸露种植(5.55g/m^(2))分别提高19.20%和302.70%,产量显著提高。该研究结果可为热带地区橡胶林林下经济高效发展、积雪草产业化种植提供技术支撑与实践参考,助力农民增收。
The forestry-medicinal plant intercropping model represents an innovative practice in modern ecological agriculture.By scientifically coordinating the growth cycles of medicinal plants and rubber trees,this approach maximizes the integrated production potential of understory spaces in rubber plantations,thereby enabling the efficient utilization of forest resources.To further establish a standardized cultivation system for forest-medicinal plant intercropping,this study explored the key cultivation techniques of Centella asiatica under rubber plantations and proposed a comprehensive cultivation model integrating orchard site selection,variety breeding,standardized planting,field management(including irrigation,seedling replenishment,fertilization,weeding,and pest and disease control),as well as harvesting and processing.The results revealed that intercropping Centella asiatica in 4-year-old rubber plantations with a north-south row orientation achieved an average dry yield of 22.35 g/m^(2),representing increases of 19.20%and 302.70%compared with greenhouse cultivation(18.75 g/m^(2))and open-field cultivation(5.55 g/m^(2)),respectively.The findings of this study provided technical support and practical reference for the efficient development of understory economy in tropical rubber plantations and the industrialized cultivation of Centella asiatica facilitating income increase for the farmers.
