Abstract

Abstract:

Yongyou grapes were used as the experimental materials to explore the effect of self-made Trichoderma microbial agent on grape quality，yield，and rhizosphere soil microbial community. The results showed that the application of self-made non-inactivated Trichoderma microbial agents significantly（p<0.05）improved grape fruit quality，with a significant increase of 28.93% in cluster weight and 13.00% in vitamin C content compared with CK （pure water）. The yield of non-inactivated Trichoderma microbial agent treatment was the highest，significantly increasing by 20.68% compared with CK. In terms of microbial community，the number of soil bacteria significantly increased by 17.13% and the number of fungi significantly decreased by 16.84% treated with non-inactivated Trichoderma microbial agents compared with CK. The results of this study can provide a reference for the promotion of microbial agent.

Key words: grape, Trichoderma, microbial agent, yield, quality
