Comprehensive Benefit Evaluation of Interplanting Different Traditional Chinese Medicinal Materials under Camellia oleifera Forest

To explore the comprehensive benefits of planting different traditional Chinese medicinal materials under Camellia oleifera forest, choose 8 years old Camellia oleifera forest, respectively plant 10 kinds of traditional Chinese medicinal materials such as Ilex asprella, Ilex pubescens, Ficus hirta, Morinda officinalis, Millettia specisoa, Polygala fallax, Flemingia philippinensis, Uraria crinita, Dietyocline griffithii and Abrus cantoniensis in the gap between Camellia oleifera trees.We choose the Camellia oleifera forest without interplanting and traditional Chinese medicinal materials without interplanting as a control.Through this experiment, the incremental of fresh fruit of Camellia oleifera and the incremental of traditional Chinese medicinal materials were investigated, and the incremental index of them were also calculated.On this basis, the rate of growth of Camellia oleifera, the medicinal value of traditional Chinese medicinal materials, the economic value of traditional Chinese medicinal materials, fertilizer and management cost of planting traditional Chinese medicinal materials were further considered.The comprehensive benefit evaluation model of interplanting traditional Chinese medicinal materials under Camellia oleifera forest was established based on Analytic Hierarchy Process and weighted rank-sum ratio.The evaluation results showed that the interplanting of Ilex pubescens and Ilex asprella in Camellia oleifera forest could achieve high comprehensive benefits, and the interplanting of Ficus hirta, Morinda officinalis and Uraria crinita could achieve the second highest comprehensive benefits.The results of this research can provide a reliable reference for interplanting of traditional Chinese medicinal materials in Camellia oleifera forest.
