Preparation of Trichoderma Microbia-fertilizer and Evaluation of Its Application to Maize Stalk Rot
In the study,Tichoderma afroharzianum Tr35 obtained in the early stage was selected as the research object. Trichoderma agent and Trichoderma microbial fertilizer were prepared through carrier screening. By measuring the plant height,root length and fresh weight of Trichoderma agent and Trichoderma microbial fertilizer with different contents,the treatments with obvious growth promotion effect were screened,and the control effect of Trichoderma agent and Trichoderma microbial fertilizer on stalk rot of maize seedling was evaluated through indoor pot experiment. The results showed that maize stalk powder had the advantages of strong water absorption,non-toxic to Tr35 and high release rate.and co-fermented with Tr35 to prepare Trichoderma agent,had a significant growth promoting effect when the soil to fertilizer was 5∶1,and achieved 51.77％ prevention effect on maize seedling stalk rot. The best growth promotion effect was achieved when the agent soil was 7∶1 with rotted sheep manure,Trichoderma microbial fertilizer was prepared in this proportion and the prevention effect of stalk rot on maize seedling reached 61.31％. The results provided a preliminary basis for the application and development of Tr35 agent and microbial fertilizer.
