Abstract: To study the effect of tobacco growth on Trichoderma population, we investigated the occurrence of Trichoderma species in the rhizosphere of tobacco plant during the period from transplanting (June) to harvesting (October) and measured relative environmental factors. Eleven species of Trichoderma were isolated, among which T. harzianum, T. viride, T. hamatum, T. atroviride, T.longibrachiatum, T. virens, T. koningii were identified, other four species Ty1, Ty2, Ty3, Ty4are new species. Of the species which occurred at high frequencies, T. harzianum and T. hamatum were most abundant in the July and T. viride in the August. The occurrence of the above three abundant species correlates significantly with the developmental phase of tobacco and correlates apparently with the soil moisture content, but not with the temperature. For the other eight species,no obvious correlation was found between the above factors and them.……
