Hanyuan Prickly Ash is a type of GI products with very deep cultural essence.From such humanistic factors as name origin,historical origin,fame,cultivation technology,and management measure,and such natural factors as climatic environment and soil conditions,this paper analysis key factors for protection of GI product Hanyuan Prickly Ash.Then it discusses about industrial development of Hanyuan Prickly Ash from suitable planting areas and climate.It proposes that we should gradually raise safety and hygienic indexes,revise and implement local standards,strengthen popularization of harmless production technologies and quality control of product,promote "enterprise + base" industrial model,and implement government marketing of brand and industry. 展开更多

Understanding how nutrient absorption processes in plants are related to arbuscular mycorrhizal(AM)association is critical for predicting the effects of AM symbiosis on elemental cycling for plants. Both mulberry(Morus alba) and Chinese prickly ash(Zanthoxylum bungeanum) are AM-associated plants, widely distributed in southwest China. It was hypothesized that if the nutrient absorption processes were efficiently associated with AM symbiosis in both mulberry and Chinese prickly ash, foliar nutrient concentrations—especially calcium(Ca)—would be primarily determined by the soil conditions in different regions. To investigate this, AM colonization levels of soils, nutrient levels in soils and leaves, and δ^(13)C values of leaves were analyzed for mulberry and Chinese prickly ash.In this study, spore density in soils with low p H was higher than that in soils with high p H. The average concentrations of sugar delivered to roots in both mulberry and Chinese prickly ash in soil with relatively low p H and soil extractable cations were higher than those in other areas.The values of foliar δ^(13)C in both mulberry and Chinese prickly ash in low soil-pH and soil extractable cations were lower than those in contrast areas, indicating that water availability was impacted by soil characteristics. The efficiency in AM-mediated processes might play an important role in translocation between soil nutrients and plant tissue.The results suggest uptake and translocation of nutrients,especially Ca, in AM-associated plants may be affected by an efficiency of AM-mediated processes. Since Sr does not appear to be similarly affected, expressing Ca and other nutrient concentrations relative to Sr could be used to evaluate whether the uptake and translocation of Ca and other nutrients are affected by AM-mediated processes. 展开更多
