Abstract The use of Trichoderma biofertilizer (BOF) has been proposed to observably elevate plant growth and crop productivity. In addition, mowing can greatly accelerate plant shoot regrowth to increase aboveground biomass and nutrient contents. We aimed to measure the effects of Trichoderma BOF on Medicago sativa growth in saline-alkali soils, especially the effects on the underlying microbial ecological mechanisms, under non-mowed and mowed conditions. We thus carried out a pot experiment to investigate the growth of M. sativa under different fertilization regimes and utilization conditions, and the corresponding responses of soil physicochemical variables and the soil microbiome were also explored. Fertilization, mowing and their interaction had significant (P = 0.000) effects on M. sativa shoot dry weight, while only fertilization had a significant (P = 0.000) effect on M. sativa root dry weight. Compared with nonamended fertilizer (CK) and organic fertilizer (OF) treatments, Trichoderma BOF treatment significantly (P

苜蓿和土壤微生物群对木霉作为碱性盐渍土壤中的生物肥料的反应

摘要 已建议使用木霉生物肥料 (BOF) 显着提高植物生长和作物生产力。此外，割草可以大大加速植物芽的再生，以增加地上生物量和养分含量。我们旨在测量木霉 BOF 对盐碱土壤中苜蓿生长的影响，特别是在未割草和割草条件下对潜在微生物生态机制的影响。因此，我们进行了盆栽试验，研究了不同施肥方式和利用条件下苜蓿的生长情况，并探讨了土壤理化变量和土壤微生物组的相应响应。施肥、割草及其相互作用对 M. sativa 茎干重有显着 (P = 0.000) 影响，而只有施肥对 M. sativa 根干重有显着 (P = 0.000) 影响。与未改良肥（CK）和有机肥（OF）处理相比，木霉BOF处理显着（P
