Abstract:
Objective: To study the variation patterns of rhizospheric soil nutrient and the content of nutrient elements for Fritillaria taipaiensis,in order to provide the theoretical base for the soil improvement and balanced fertilization during the artificial cultivation. Method: Totally 14 samples of rhizospheric soil of Fritillaria taipaiensis from different origins and years were taken as the research objects. Total N,available N,total P,available P,total K,available K,organic matter,pH and 7 nutrient element contents (Ca,Mg,Na,Mn,Zn,Cu and Ni) were analyzed by the soil agrochemical analysis method combined with the atomic absorption spectrophotometry. SPSS 22.0 software was applied for data multiple comparison and correlation analysis. Result: The all results showed significant differences (P<0.05) and certain relative correlations between samples of different origins or years, and the rhizospheric soil nutrient or the content of nutrient elements of F. taipaiensis. The content of total N,available N,total P,available P and organic matter of rhizospheric soil collected from cultivated varieties decreased with the increase of years,and the content of total K,available K and pH decreased first and then increased. However,the soil physical and chemical properties of wild varieties had no obvious change with the increase of years. The content of Ca,Mg,Na and Cu of soil from cultivated varieties decreased with the increase of years,while the content of Mn decreased first and then increased. And Zn and Ni showed no significant change with the increase of years. Compared with cultivated varieties,the content of Ca,Mg,Na,Mn and Cu increased first and then decreased. The content of Zn and Ni showed no obvious change. In general,the rhizospheric soil nutrient and the content of nutrient elements for wild F. taipaiensis were superior to those of cultivated varieties. Conclusion: The third year is the turning point of F. taipaiensis growth. The rhizospheric soil nutrient and the content of nutrient elements decreased obviously after three years. Attention shall be given to the balanced fertilization,the improvement of soil quality and the prevention of the cropping during cultivation of F. taipaiensis.
