混交林的生态和经济效益越来越引起人们的关注，为了探讨混交林中各树种的生化关系，研究了分布于陕西省宁陕县火地塘林场的华山松(Prunus armandii)和锐齿栎(Quercus acutissima)林下土壤及凋落物浸提液对油松(Prunus tabulaeformis )种子发芽、胚根和幼茎生长的影响.结果表明：各个浓度水平的两种森林林下土壤浸提液对种子发芽，幼茎生长和胚根生长都无显著影响；各个浓度水平的凋落物浸提液对胚根和幼茎生长有显著影响，经α=0.05水平检验，1∶10液对胚根生长有显著的促进作用，原液和1∶20液无显著影响，1∶10液和1∶20液对幼茎生长有显著的促进作用，而原液无显著影响.

In recent years, much attention has been given to the economic and ecological benefits of mixed forest.In this paper, the grow th of Prunus tabula eformis seed, treated with the aqueous extracts of Prunus armandiii and Quercus acu tissima forest which lies in Ningshan County，Shanxi Province, is studied by v a riance analysis, so that the constitution of trees in the mixed forest is also d iscussed. The results indicate: each concentration level of aqueous extracts from soil un der two kinds of forests has no significant effect on seed-pullulating, radicle and radicle growth; each concentration level of aqueous extracts from forest li tter has significant effect. The concentration of 1∶10 equeous extracts from li tter accelerates the radicle growth significantly, but those of the original and 1 ∶20 have no significant effect; and the concantions of 1∶10 and 1∶20 accelera te the tender stem growth, but the original has no significant effect.
