  1. 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

    利用不同栽植代數杉木人工林根際土、非根際土及杉木各器官浸提液進行杉木種子發芽試驗,研究杉木人工林自毒作用,研究結果表明:杉木林根際土及非根際土中均存在抑制杉木種子萌發的物質,隨栽植代數增加抑制作用更趨明顯;杉木各器官浸提液對杉木種子萌發也有抑制作用,其中以杉木葉的抑制作用最為明顯,杉木林下常見植物對杉木種子發芽則表現為低促高抑效應,說明杉木人工林存在自毒作用,這可能是杉木連栽障礙的原因之一。
