摘　　要：利用原子吸收光谱和常规生长量测定法,研究了木霉菌T23对7种微量元素Mn2+、Ca2+、Mg2+、Cu2+、Zn2+、Fe2+、Mo6+的吸收利用及7种微量元素对木霉菌T23生长的影响。结果表明:木霉菌T23对7种微量元素的吸收率存在明显差异,能够大量吸收Mg2+、Zn2+、Cu2+、Ca2+、Mn2+和Fe2+,基本不吸收Mo6+元素。在微量元素对木霉菌T23生长的影响方面,则表现为Ca2+、Mn2+、Zn2+可不同程度地促进木霉菌T23产孢,Cu2+、Mn2+、Mg2+、Ca2+、Zn2+在组合培养基中促进木霉菌T23菌丝生长,Mo6+抑制木霉菌T23的菌丝生长和产孢。Using atomic absorption spectrometry and the conventional measurement method of growth, the effect of Trichoderrna T23 on the absorption, utilization and growth of Mn2＋ ,Ca2＋, Mg2＋, Cu2＋, Zn2＋ ,Fe2＋ and Mo6＋ were studied in the present study. The results showed that the utilization percents of Trichoderma T23 to Mg2＋ , Zn2＋ , Cu2＋ , Ca2＋ , Mn2＋ , Fe2＋ and Mo6＋ were significantly different. Trichoderma T23 can largely absorb Mg2＋ , Zn2＋ , Cu2＋ , Ca2＋ , Mn2＋ and Fe2＋ , but can not use Mo6＋ in PD and compound culture media. On the effect of microelements on the growth of Trichoderma T23, Ca2＋ , Mn2＋ and Zn2＋ could promote sporulation of Trichoderma T23. Cu2＋ , Mn2＋ , Mg2＋ , Ca2＋ and Zn2＋ could promote mycelium growth of Trichoderma T23 in compound culture media. Mo6＋ could inhibit mycelium growth and sporulation of Trichoderma T23.
