This experiment was carried out to clarify the effect of cultural years on the growth and yield of Fritillaria thunbergii. It was planted on Middle September, with high ridge between $100cm\;(2 lines){\times}interrow 9cm$ and N-P-K=8.1-11.2-8kg/10a of fertilizers treated basal application...
This experiment was carried out to clarify the effect of cultural years on the growth and yield of Fritillaria thunbergii. It was planted on Middle September, with high ridge between $100cm\;(2 lines){\times}interrow 9cm$ and N-P-K=8.1-11.2-8kg/10a of fertilizers treated basal application. Cultural years were 1, 2 and 3 years, the block of 2 or 3 years was additional same amount of fertilizers at early spring. The results were summarized are as follows. Rapid bulb filling stage was begun 32 days after sprouting, and completed bulb growth needed 72 days. Dry weight/fresh ratio of bulb was ranged from $27.2{\sim}30.3$%. Rate of over 5g bulb weight was 89% at 1 year, 87% at 2 years and 77% at 3 years and bulb yield were 638kg/10a at 1 year. Compared with yield at 1 year, the yield increased 88% at 2 years and 189% at 3 years.
