摘要
This paper mainly studies the effects of different propagation materials and cultivation years on the yield of Polygonatum odoratum under the forest.In this study,the cultivation experiment of P.odoratum was carried out by using the stem tip,stem body and seeds of P.odoratum as propagation materials.The yield of P.odoratum in different cultivation years with propagation by rhizome was also investigated.That is,the continuous growth of P.odoratum and the yield of P.odoratum each year after cultivation was statistically analyzed.The results showed that the germination rate under stem tip cultivation was fast,and the emergence time was also fast,which was more than 2 weeks earlier than that under stem body cultivation,and the seedling emergence rate reached 100%.The stem body was a new plant formed by sprouting from the buds of internodes,and the emergence rate was more than 95%.P.odoratum propagated by rhizome was harvested in the third or fourth year after cultivation,and the third year was the best harvest time.
