RESUMO
In this study,field cultivation experiments of Notopterygium incisum had been carried out for three years, and samples had been collected monthly during growth seasons, and biomass and nutrient elements of aerial and underground part of sampled plants had been determined to assess their seasonal and interannual dynamics respectively. The results showed that biomass of underground part (dry weight) increased mainly in the second year after seedling transplanting, i.e., biomass increased about 32 times in the second year whilst less than 6 times and 2 times in the first year and in the third year, respectively. Therefore, efforts for yield improvement should be focused on the first two year in artificial cultivation of N. incisum. Accumulation of nutrient elements increased steady in the underground part during the first and second year, then showed a sharp decline in the first phase of growth season in the third year, while its accumulation in July to August of third year was higher than the value of second year. Ca, Fe, B and Zn were larger demand nutrient elements to meet growth demands whether for the underground part or aerial part during the second year and third year for N. incisum cultivation. This result provided instructional guidance and scientific basis for artificial cultivation and specific fertilizer of N. incisum.
RESUMO
Notopterygii Rhizoma et Radix, the underground part of Notopterygium incisum and N. franchetii, is used as a classical traditional Chinese medicine, and as raw materials for 262 Chinese patent drugs production in 694 pharmaceutical factories currently. It plays an important role in the whole Chinese medicine industry with irreplaceable important economic and social values. However, wild resource of was abruptly depleted, and large-scale artificial cultivation has been inapplicable. In this study, Utilization history and the industrialization status of Notopterygii Rhizoma et Radix were summarized. Resource distribution, ecological suitability of Notopterygii Rhizoma et Radix and core technologies for seeds production, seedling breeding, large-scale cultivation has been reported by current studies, and basic conditions are already available for industrialization production of Notopterygii Rhizoma et Radix. However, there still some key technical problems need to be solved in the further research, and some policy dimensions need to be focused on in the coming industrialization cultivation of Notopterygii Rhizoma et Radix.
RESUMO
The major contributing factors for growth of endangered medicinal plants of Fritillariae Cirrhosae Bulbus were screened on the GIS platform by using the MaxEnt model, and spatial distribution data of the medicine quality suitability were generated by geostatistics interpolation based on reported measured data of ecology and quality suitability assessment. On this basis, a functional production cultivation regionalization with high feasibility and operability were formatted for protection, wild monitoring, and cultivation of this plant by fuzzy superposition of spatial suitability data of ecology and quality, as well as integrated with land use and cover data. Therefore, a novel assessment and regionalization method were presented for ecology, growth and quality suitability of the Chinese traditional medicinal plants. This method is expected to overcome shortage of traditional regionalization methods difficult to distinguish the contribution of ecological factors and quality factors, which provide an innovative theory and methodology for regionalization, and is helpful to practical application of wild resource protection, monitoring, and commercialization cultivation for traditional Chinese medicinal plants.
