Abstract:
【Objective】 To clarify the appropriate sowing date and sowing amount of ripe seedling raising in
Angelica sinensis producing areas by carrying out its seedling raising test in cultivated fields and comparative test of drug preparation stage.
【Methods】 The experiment adopted the two-factor split zero group design by setting up different sowing dates and sowing amounts to cultivate seedlings in the cultivated fields of
A.sinensis, and measured the morphological indices and calculated the survival rate, early-bolting rate, plant characteristics, yield and ferulic acid content after transplanting.
【Results】 There were differences in the size, yield and survival rate after transplanting, early-bolting rate, morphological indexes, crude drug yield and ferulic acid content of
A.sinensis seedlings.The root weight of
A.sinensis seedlings in the first and second sowing date ranged from 0.45-0.63 g, which met the production requirements.In the second sowing date, the yield was 76.26% higher at 5 kg/667m
2 than that at 7 kg/667m
2 in the same sowing date and the early-bolting rate was 0.
【Conclusion】 In the production area of
A.sinensis, seedlings should be raised in cultivated fields in late June, the sowing amount controlled in the range of 5-6 kg/667m
2, and the seedling age controlled in 110 days, which might meet the production demand for the
A.sinensis seedlings.
