Abstract: Optimal formula of the wettable powder of Trichoderma reesei FS10-C,with functions of plant growth-promoting and heavy-metal-resistant effect,was defined by screening carriers,wetting agents,dispersing agents,and protecting agents,and a pot experiment was conducted to determine its effects on the growth of Sedum plumbizincicola. The results showed that the optimal formula of the wettable powder was confirmed as follows:10% Trichoderma reesei FS10-C conidia,74.6% kaolin,5% dodecyl-benzene sulfonic acid sodium,10% sodium lignosulphonate,and 0.4% vitamin C. The suspension rate of the formula was 72.48%,which matched the national formulation standard. Results of the pot experiment demonstrated that 500 times dilution of Trichoderma reesei FS10-C conidia WP presented a favorable growth-promoting effect on S. plumbizincicola,under which the aboveground fresh weight and dry weight of the plant increased by 14.70% and 23.14% respectivelycompared with the controls.
