Preliminary Analysis on Vegetative Growth of Dryopteris crassirhizoma
摘要
Abstract
In order to understand the growth law of Dryopteris crassirhizoma,2～4-year-old Dryopteris crassirhizoma with the same habitat was selected to measure and analyze a total of 11 growth indicators,including crown width,plant height,leaf number,leaf length,leaf width,leaf fresh weight,leaf dry weight,rhizome fresh weight,rhizome dry weight,total fresh weight and total dry weight.The results showed that the growth indexes of Dryopteris crassirhizoma increased significantly with the increasing of age.The growth rate of crown width,leaf number,leaf length,leaf width,leaf fresh weight,leaf dry weight,rhizome dry weight,total fresh weight and total dry weight increased rapidly in the third year,but slowed down in the fourth year.The growth rate of plant height and rhizome fresh weight slowed down in the third year,increased rapidly in the fourth year.The study found that compared to the 2-year-old Dryopteris crassirhizoma,the dry matter accumulation of rhizome was nearly 19 times in two years,which provided a favorable guarantee for the rhizome of Dryopteris crassirhizoma to be used as medicine.关键词
