Effect of Nitrogen Fertilizer on Carbon Metabolism and Growth and Development of Acanthopanax senticosus Seedlings
To study the effect of different nitrogen application rates on the growth and carbon metabolism of
Acanthopanax senticosus
seedlings
and screen out the rational fertilization conditions
in order to provide basis and guidance for scientific fertilization of artificially cultivated
A
.
senticosus
.
Method:
2
A single-point
single-factor field experiment was conducted to study the seedlings of growing evenly
A
.
senticosus
.Five different nitrogen application treatment groups were set up to treat the seedlings
namely N1 group (30 g·m
-2
)
N2 group (60 g·m
-2
)
N3 group (90 g·m
-2
)
N4 group (120 g·m
-2
)
N5 group (150 g·m
-2
) and CK group (0 g·m
-2
)
respectively.Three months later
plant height
root circumference
stem circumference
root-shoot ratio and SPAD were measured at harvest time.The contents of protein
sucrose
starch
soluble sugar and reducing sugar in fresh leaves were measured.
Result:
2
N3 treatment was the best treatment method for the growth and development of
A
.
senticosus
seedlings
and the growth of
A
.
senticosus
seedlings was the best under this treatment.The protein content of
A
.
senticosus
seedlings in N3 treatment was the highest.Starch and sucrose were best accumulated in N5 treatment group and CK treatment group.N5 treatment had the highest soluble sugar content and reducing sugar content.
Conclusion:
2
There is a dose-effect relationship between the growth and development of
A
.
senticosus
seedlings; that is to say
low and high nitrogen application treatments will cause stress on
