Effect of Transplanting Densities on Growth, Development, Yield and Quality of Astragalus membranaceus var. mongholicus
Astragali Radix is an important medicinal and edible herb. To achieve standardized cultivation of Astragali Radix and improve cultivation results
Astragalus membranaceus
var.
mongholicus
was cultivated with a row spacing of 30 cm and different plant spacing (8
10
12
14
16 cm) in a test base of Longxi County
Gansu Province.
Method:
2
The growth and development dynamics of green strains and the yield and quality of medicinal materials were measured
and the comprehensive evaluation of membership function was used to determine the rational transplanting density and explore the standard production technology of
A
.
membranaceus
var.
mongholicus
.
Result:
2
The transplanting topping had a significant effect on the growth and development of
A
.
membranaceus
var.
mongholicus
under the condition of the row spacing of 30 cm. With the increase of topping
the biomass of astragalus on the ground decreased
and the ratio of root to shoot increased
but the yield of medicinal material per unit area decreased. The appearance traits were improved as the transplant density decreased. Under the row spacing of 14 cm
the content of astragaloside and calycosin-7-glucoside were the highest. Under the row spacing of 8-16 cm
the content of root extract of Astragali Radix was better than the
Chinese Pharmacopoeia
standard. The comprehensive evaluation index of each plant spacing treatment was 14 cm

12 cm in turn.
Conclusion:
2
Combined with the comprehensive evaluation of yield and economic benefit
the optimal transplanting plant spacing and row spacing were 30 cm×14 cm (with the density of 238 100 strains/hm
