  7. The self - poisoning effects of chinese fir plantation are studied through the seed germination experiment with the extracts of organs, bulk soils and rhizosphere soil of different rotation plantations. the results are as follows : there are some poisonous substances inhibiting germination of chinese fir seeds in soils of chinese fir plantations. the inhibiting effect becomes stronger and stronger with increase of planting generations. extracts from the organs of chinese fir trees also have some inhibiting effects on seed ' s germination, but the effect of leaf is the strongest. lower concentration extracts of underground vegetation may be favorable to the seed ' s germination whereas the higher concentration will reverse the results. it indicates that the “ self - poisoning ” effects of chinese fir plantations might be one of the reasons for poor natural regeneration and soil degradation of chinese fir plantation
