Study on the Structure of Management in Seed Forest of Phellodendron amurense

Abstract

Through the theory of forest level and structure of forest population,we took the level of Ⅰ and Ⅱ as choiceness forest level of Phellodendron amurense in the seed forest management,and Ⅲ as disuse.We brought forward that the best proportionment for male and female had been 1∶1.The quality of seed and the progeny test showed that the thousand kernels weight and germination percentage of level Ⅰ and Ⅱ were higher than control,and they were by 7.95%～15.91% and 2%～12% respectively.
