Abstract:
The annual Scutellaria baicalensis cultivars were used to study the effects of planting density on yields and dry matter distribution，and to determine the most suitable planting density for the artificial cultivation of Scutellaria baicalensis.The results showed that the planting destiny had no significantly effect on the main stem branching numbers and stem height.However，it had significantly on stem diameter and root length，and showed a trend of Ⅴ(row spacing 20cm)>Ⅳ(row spacing 16cm)>Ⅲ(row spacing 12cm)>Ⅱ(row spacing 10cm)>Ⅰ(row spacing 5cm).The numbers of forked blade root had increased and the root had become slender with the increase of planting destiny，while the appearance quality of root had become poor.Group root weight，the floor area of dry weight and the root canopy ratio improved significantly with the increasing of planting destiny in certain range.The results showed that raised the planting destiny were the effective step to increasing the yield of Scutellaria baicalensis.With the increasing of planting destiny，the root weight and floor area of dry weight of per plant decreased，and showed a tread of Ⅴ>Ⅳ>Ⅲ>Ⅱ>Ⅰ；the effect of planting density on flavonoids content of root，stem and leaf，flavonoids content of root showed Ⅱ>Ⅲ>Ⅰ>IV>Ⅴ，flavonoids content of stem showed Ⅲ>Ⅱ>Ⅰ>IV>Ⅴ，flavonoids content of leaf Ⅱ>Ⅲ>Ⅳ>V>Ⅰ.In a word，proper density；coordinate the relationship between individual and group and the relationship between the ground part and underground part；prompt organ material distribution rationally and the best utilize of natural environment，such as light，temperature，water，CO2，fertilizer were the most important steps to achieved high yield and superior quality of Scutellaria baicalensis.
