Variation Pattern of Rhizospheric Soil Nutrient for Fritillaria taipaiensis
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:
2
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:
2
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:
2
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
