Abstract:
Taking ‘Zhonggan 21’ cabbage as the test material,seven treatments including control,microplastics (MPS),and mixed application of straw and microplastics (SMPS) were set up.Illumina high-throughput sequencing was used to perform high-throughput sequencing of ITS1 region and FunGuild functional prediction to study the effects of microplastics and straw application on soil fungal microbial communities,in order to provide reference for ecological research on microplastic pollution in coastal saline alkali areas.The results showed that the number of species and Chaol index observed in MPS2 treatment (microplastic concentration 5%) increased，the relative abundance of soil dominant phylum Ascomycota in SMPS2 treatment increased significantly，and the relative abundance of microbial functional pathological nutrition type decreased significantly.Compared with the control，the Shannon index and Simpson index of the fungal community in the soil added with microplastics decreased，and the Chao1 index increased when the microplastics concentration was 5%.The addition of microplastics affected the alpha diversity of the soil to a certain extent.After adding straw，the above indexes showed a decreasing trend.In terms of soil community structure，the dominant phylum of fungal community was Ascomycota regardless of whether microplastics were added to the soil or not and whether microplastics were mixed with straw.The relative abundance of Ascomycota increased with the increase of microplastics concentration.The relative abundance of Ascomycota increased significantly after the addition of straw.The relative abundance of SMPS2 Ascomycota was more than 94%.The addition of straw provided soil aeration，nutrients and other environmental conditions for microorganisms，resulting in changes in the dominant genera of soil microorganisms.The relative abundance of saprophytic microorganisms increased and the relative abundance of pathological nutrients decreased.
