Effect of Micro-fertilizer Containing Rare Earth on Growth,Yield and Quality of Angelica sinensis
To investigate the effects of micro-fertilizer containing rare earth of different types and concentrations on the growth,yield and quality of
Angelica sinensis
.
Method
2
On the basis of the single-factor randomized block design, the growth and index components of
Angelica sinensis
were determined with rare earth-containing nitrate and chloride micro-fertilizers of different concentrations as foliar fertilizers.
Result
2
Spraying 0.8 g·mL
-1
rare earth-containing chloride micro-fertilizer could increase the economic yield of
A. sinensis
, with the fresh yield per mu (1 mu≈667 m
2
) reaching 855.4 kg and the dry yield per mu 350.7 kg,which increased by 15.16% and 28.70% respectively compared with that in the control group CK1. Spraying 1.2 g·mL
-1
rare earth-containing nitrate micro-fertilizer could promote the growth and development of
A. sinensis
and significantly increase the content of index components, with the plant height reaching 93.05 cm,the stem diameter 15.60 mm,the root diameter 16.10 mm,the main root length 36.5 cm,and the number of leaves 11.25 pieces per plant, which increased by 32.76%,31.98%,41.98%,53.36%,and 45.16%, respectively, compared with those in the control group CK2. Besides, the content of ferulic acid,volatile oil,ligustilide, and extract was 0.96%,0.41%,0.30% and 48.76%,respectively,which increased by 12.94%,17.14%,11.11%, and 12.07%,respectively,compared with that in the control group CK2.
Conclusion
2
Spraying 0.8 g·mL
-1
rare earth-containing chloride micro-fertilizer and 1.2 g·mL
-1
rare earth-containing nitrate
micro-fertilizer can promote the growth and development of
A. sinensis
,improve the medicinal properties,and increase yield and quality. Rare earth-containing micro-fertilizers can be applied in the standardization of
A. sinensis
cultivation, which can change the production status of
A. sinensis
that depends on chemical fertilizers and single fertilization, and promote the green, organic and ecological cultivation of
