摘要: 以对植物具有促生作用兼具重金属抗性的里氏木霉FS10-C为功能菌株,通过对载体、润湿剂、分散剂、保护剂的筛选,确定了里氏木霉FS10-C可湿性粉剂的最佳配方,并测定其施用对伴矿景天生长的影响。结果表明,该可湿性粉剂最佳配方为:孢子粉10%、高岭土74.6%、十二烷基苯磺酸钠5%、木质素磺酸钠10%、维生素C 0.4%。该配方悬浮率可达到72.48%,符合国标要求。盆栽实验结果显示,该制剂500倍稀释液对伴矿景天有良好的促生效果,使其地上部鲜重和干重与对照相比分别提高了14.70%及23.14%。

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.
