Study on Autumn Seed Collection and Seedling Raising of Platycladus orientalis
Platycladus orientalis is a specialty tree species in China.As an evergreen tree,it is distributed in most parts of the country and has made positive contributions to urban greening construction.P.orientalis has important cultivation economic value,both cultivated and wild,and its requirements for soil quality are not high.Whether it is dry and barren mountains or humid and fertile areas,it can grow smoothly.At present,P.orientalis has become one of the most widely used ornamental trees in China.In order to further improve the economic value of P.orientalis and ensure the cultivation rate,it is necessary to conduct in-depth research on the two aspects of seed collection and seedling raising.In this paper,the autumn seed collection and seedling raising of P.orientalis were studied.
