Effect of Different Nitrogen Application Rates on Growth, Yield and Quality of Two-year-old Belamcanda chinensis
To investigate the effects of different nitrogen application rates on the growth, yield and quality of
Belamcanda chinensis
and to provide a theoretical basis for the quality and production efficiency improvement of
B. chinensis
.
Method
2
A field experiment was carried out on the basis of 120 kg·hm
-2
phosphate and potassium fertilizers, with five nitrogen fertilizer treatments: 0 (N
0
), 60 (N
60
), 120 (N
120
), 180 (N
180
) and 240 (N
240
) kg·hm
-2
. The effects of different nitrogen application rates on the agronomic traits, yield, mineral element accumulation and flavonoid content of
B. chinensis
were studied.
Result
2
Application of nitrogen fertilizer was beneficial to dry matter accumulation and significantly increased the yield of rhizome. After the application of nitrogen fertilizer, the yield of rhizome increased by 48.75%-86.62%. The nitrogen application at 60-180 kg·hm
-2
increased the active components such as tectoridin, iridin and irisflorentin, while it was not conducive to the accumulation of tectorigenin and irigenin in the rhizome. The accumulation of Mn and Fe reached the highest when the nitrogen application rate was 120 and 60 kg·hm
-2
, respectively. The principal component analysis of active component content showed that the comprehensive score was ranked as N
180
>
N
120
>
N

>
N
240
>

. The correlation analysis indicated that the tectoridin content had a positive correlation with N accumulation and a negative correlation with Ca accumulation in
B. chinensis
. The content of tectorigenin was negatively correlated with N accumulation and positively correlated with Ca accumulation. The content of irigenin had positive correlations with Ca and Zn accumulation.
Conclusion
2
The nitrogen application at 120-180 kg·hm
-2
can increase the rhizome yield and the content of tectoridin, iridin and irisflorentin in the rhizome, so as to improve the yield and quality of this herb.
