Effects of Planting Amorphop hallus bulbifer in Rubber Forest on the Soil Fungal Community
摘要
Abstract
This study aimed to explore the effects of planting Amorphop hallus bulbifer under a rubber forest on the soil fungal community and provide a scientific basis for the high-yield cultivation of A.bulbifer under a rubber forest and its in-dustrial development.The fungal community structure and diversity of nonintercropped soil and intercropped A.bulbifer soil(rhizosphere and root zone)under a rubber forest in Puwen Town,Jinghong City,were compared and analyzed through ITS sequencing and bioinformatics analysis.The results showed that the abundance and diversity of the fungal community in the soil without A.bulbifer(ZYK10)were significantly higher than those in the rhizosphere soil(ZY10)and root soil(ZYX10)intercropped with A.bulbifer.A total of 10 phyla of soil fungal communities were detected in the three groups of soil samples,namely Basidiobolomycota,Mucoromycota,Kickxellomycota,Rozellomycota,Glomeromycota,Zoopagomycota,Chytridio-mycota,Basidiomycota,Mortierellomycota,and Ascomycota.Changes in soil structure or certain substances secreted by the root system of A.bulbifer may inhibit the development and reproduction of Rozellomycota;certain substances secreted by the root system of A.bulbifer promote the development and reproduction of fungi belonging to Basidiobolomycota,Basidiomy-cota,and Glomeromycota.LEfSe analysis revealed that all three groups of soil samples had distinguishable biomarkers.Planting A.bulbifer had significant effects on the community structure and diversity of soil fungi in rubber forests,and the root exudates of A.bulbifer may promote or inhibit the growth,development,and reproduction of certain fungi.By analyzing the diversity of fungal communities in the soil(rhizosphere and root zone)where A.bulbifer was planted under a rubber forest,and the soil where it was not planted,this study clarified the impact of planting A.bulbifer on soil fungal diversity and pro-vided a reference for the development and utilization of the underrubber forest economy.关键词
