Abstract:
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.
