Abstract: To explore the effects of Trichoderma fertilizer on wheat growth, disease resistance, yield and soil enzyme activities under salt stress.Plant height, root length, root number, physiological and biochemical indexs, diseased ears rate, disease index, control efficiency, thousand seeds weight and soil enzyme activity of Xinong 979 were measured under salt stress by using Trichoderma Fertilizer instead of 30% chemical fertilizer and using 100% chemical fertilizer.The results showed that compared with chemical fertilizer, the application of Trichoderma fertilizer significantly increased plant height, root length and root number of wheat by 10.91%, 43.45% and 42.86% under salt stress, respectively.Secondly, under salt stress, the activity of phenylalanine ammonia-lyase (PAL) and content of chlorophyll in wheat leaves increased significantly after Trichoderma fertilizer application, while the contents of malondialdehyde (MDA) and hydrogen peroxide (H2O2) in wheat leaves were significantly lower than that of chemical fertilizer.Moreover, the incidence rate of Fusarium head blight in wheat after Trichoderma fertilizer application was significantly lower than that in wheat applied with chemical fertilizer, with the control efficiency of 88.36% to Fusarium head blight.The thousand grains weight of wheat grain increased by 9.5% after Trichoderma fertilizer application compared to control.In addition, the activities of soil enzymes including urease, sucrase, dehydrogenase, catalase, peroxidase and polyphenol oxidase in wheat rhizosphere and non-rhizosphere were much higher after Trichoderma fertilizer application.In sum, under salt stress, Trichoderma fertilizer enhanced the disease resistance of wheat by increasing activities of antioxidant enzymes and chlorophyll content as well as improving the ecological environment of soil, subsequently increasing yield and improving quality of wheat grains.
