Abstract:
A two-factor design experiment with three different soil and light intensity levels was conducted to exploring the effect of soil and light intensity on growth and photosynthesis of Lycoris longituba utilizing flowering bulb of Lycoris longituba.The results showed that leaf length，dry weight and wet weight ratio of bulb and Pn were raised as light intensity increasing，but leaf number was reduced.Although appropriate soil nutrient would improve leaf number and length，dry weight and wet weight ratio of bulb，the more nutrient would have no significant effect and depress them later.The light intensity had a positive effect on Pn while soil had not.The interaction of two factors had significant effect as well，and the influence of light intensity was bigger.In conclusion，Lycoris longituba was a sun plant at its foliage stage，so in order to improve its production appropriate nutrients and sufficient light were needed.
