| Abstract: | The effect of the factors of clone, site and stand on the yield and quality of Chinese fir seed was analysed by using qualitative theory I model The results showed that the factors of site, clone and stand had significant effect on the yield and quality which suggested that the orchard site should be located on sunny exposure slope and its stand closed degree be less than 0 6,and the clone be high yield and quality ones such as Yc 65033 |
