Correlation Analysis Between Bulb Quality and Rhizosphere Soil Factors of Fritillaria taibaiensis
To explore the correlation between bulb quality and rhizosphere soil factors of
Fritillaria taibaiensis
of different origins and years
in order to provide theoretical basis for the high quality and safe production of
F
.
taibaiensis
.
Method:
2
Totally 11 samples of bulb and rhizospheric soil of
F
.
taipaiensis
of different origins and years were taken as the research objects. Available N
available P
available K
organic matter
pH and six soil enzyme activities in rhizosphere soils were determined by soil agrochemical analysis method. Peimisine and nine nucleosides in
F
.
taibaiensis
bulbs were determined by HPLC
and total alkaloid content was determined by UV. SPSS 22.0 software was used to analyze the correlation of the measured data.
Result:
2
There were significant differences in rhizosphere soil factors and bulb quality between
F
.
taibaiensis
of different origins and years (
P
<
0.05). In terms of soil factors
the contents of available N
available K
organic matter and six soil enzyme activities in rhizosphere soil of wild varieties were higher than those of cultivated varieties
while the contents of available P and pH were lower than those of cultivated varieties. With the increase of growth years
the soil nutrient index of cultivated varieties showed different change trends
while that of wild varieties did not change significantly. However
most of the soil enzymes in both groups decreased in varying degrees. In terms of bulb quality
the contents of nine nucleosides and alkaloids in
F
.
taibaiensis
bulbs decreased with the increase of growth years
with larger change trends of cultivated varieties
while that of wild varieties was not significant. The contents of nucleosides and alkaloids in most cultivated varieties were higher than those in wild varieties. The correlation analysis showed certain correlations between soil factors in rhizosphere as well as soil factors and bulb quality. In general
soil nutrient status and bulb quality decreased with the increase of years.
Conclusion:
2
The quality of
F
.
taibaiensis
is mainly affected by its rhizosphere soil factors. In the process of field conservation and artificial cultivation
attention shall be paid to increase or decrease of the content of soil nutrients and their proportional relationship according to actual situations
