Abstract:

Trichoderma harzianum belongs to Trichoderma, it is a widely used biological agent and a fungus with various values. With the extensive application of Trichoderma harzianum in agricultural production, different functions of Trichoderma harzianum in plants have been widely concerned. This paper summarized the biological control mechanism of Trichoderma harzianum, including antibacterial effect, induced resistance and competition. It also reviewed the application of Trichoderma harzianum in biological control, plant growth promotion, quality improvement and salt tolerance. The paper further elaborated that there are still problems and deficiencies in the application of Trichoderma harzianum in plants, which need to be solved urgently. Finally, this paper discussed the application prospect of Trichoderma harzianum in plants under the background of green agriculture and pointed out the future research direction, aiming to achieve a more rational and safe use of Trichoderma harzianum in plants in agricultural production.

Key words: Trichoderma harzianum, biological control mechanism, promoting plant growth, improving quality, salt tolerance
