[Objective] The paper aimed to study the accumulation and distribution rule of dry matter in Scutellaria baicalensis Georgi with different growth life-spans.[Method] The two-year-old skullcaps had been sampled since March 29,respectively before turning green,after turning green,during the squaring period,flowering stage,filling stage,ripe period,before wither and after wither;while the three-year-old skullcaps were sampled one time every 15 days from March 26 until the shoot part was completely withered on October 13.[Result] It was verified that stems and leaves of the domestically grown skullcaps grow primarily in the earlier period;in the intermediate stage of growth,the organic matters are massively transported to the reproductive organs,such as flower buds and fruits,etc.;in the final period,which is the main period of forming the root output,the organic matters were massively transferred to roots.The crisscross curved about the proportion of shoot and root weight of two and three-year-old skullcaps shaped like a “scissor” [Conclusion] The research could provide scientific basis for the high-efficient cultivation and timely harvest of domestic Scutellaria baicalensis Georgi.

[Result] It was verified that stems and leaves of the domestically grown skullcaps grow early in the earlier period; in the intermediate stage of growth, the organic matters are massively transported to the reproductive organs, such as flower buds and fruits, etc . in the final period, which is the main period of forming the root output, the organic matters were massively transferred to roots.The crisscross curved about the proportion of shoot and root weight of two and three -year-old skullcaps shaped like a “scissor” [Conclusion] The research could provide scientific basis for the high-efficient cultivation and timely harvest of domestic Scutellaria baicalensis Georgi.
