Description
Summary:Background and aims The problem of desertification is becoming increasingly serious in the Zoige Plateau. How to carry out vegetation restoration more efficiently in desertified area has been a hotspot. This study aims to improve the vegetation restoration capacity in the desertified area of Zoige Plateau. Methods In this study, Elymus sibiricus , Elymus dahuricus Turcz and Avena sativa were used as restoration plants in desertified areas. The application concentrations of palygorskite fertilizers (PF), bacterial fertilizers (BF) and phyto-hormones were determined by orthogonal test. The restoration effects were determined based on the fractional vegetation cover (FVC), soil physicochemical properties and soil microbial community after restoration. Results The results showed that FVC was improved in desertified lands through the addition of PF, BF and phyto-hormones, and the best performance of the combined application improved the FVC up to 67.9%. Meanwhile, the contents of available phosphorus and available nitrogen were also significantly increased compared with the control. Moreover, 16S sequencing analysis showed that Flavobacteria and Herbaspirillum were increased in the plots with high FVC compared to the ones in the control ( p
