| 枇杷根际土壤用木霉P3.9菌株孢子悬浮液灌根，Illumina平台高通量测序，分析引入木霉P3.9菌株对枇杷根际细菌多样性及其群落组成的影响。结果表明枇杷根际土壤细菌优势菌群为Proteobacteria变形杆菌门、Actinobacteria放线菌纲、Propionibacteriales丙酸杆菌目、Nocardioidaceae类诺卡氏菌科、Aeromicrobium气微菌属。引入木霉P3.9菌株虽然导致枇杷根际细菌多样性略有下降，但是优势菌群种类及数量未发生变化。Nitrospirae硝化螺旋菌门1门；Nitrospira硝化螺菌纲、Phycisphaerae纲2纲；Desulfurellales硫还原菌目、Nitrospirales硝化螺旋菌目、Tepidisphaerales目3目；Desulfurellaceae硫还原菌科、Tepidisphaeraceae科、Rhodothermaceae科3科；Nitrospira硝化螺旋菌属、Nitrosospira亚硝化螺菌属、Nitrosomonas亚硝化单胞菌属、Chryseobacterium金黄杆菌属4属；Micromonospora auratinigra、Pseudonocardia khuvsgulenisi、Bacteroides vulgatus、Arabidopsis thaliana 4种急剧增加。Thermoleophilia油菌纲1纲；Corynebacteriales目、Frankiales目、Solirubrobacterales土壤红球菌目、Kineosporiales目、Ktedonobacterales目5目；Nocardiaceae诺卡氏菌科、Geodermatophilaceae科、Mycobacteriaceae分枝杆菌科、Hyphomicrobiaceae生丝微菌科、Solirubrobacteraceae土壤红色杆菌科、Cryptosporangiaceae 科6科；Amycolatopsis拟无枝酸菌属、Smaragdicoccus属、Solirubrobacter土壤红杆菌属、Blastococcus芽球菌属、Azohydromonas嗜血杆菌属、Rhodococcus红球菌属、Bauldia属、Nocardia诺卡氏菌属、Micromonospora小单孢菌属、Parviterribacter帕维特杆菌属、Fodinicola?矿生菌属11属；Rhodococcus wratislaviensis、Nocardia neocaledoniensis、Fordinicola feengrottensis 3种急剧下降。说明木霉P3.9菌株促使枇杷根际有益细菌增加，致病细菌减少，对连作枇杷根际土壤有修复作用。 |

| In order to analyze the effects of Trichoderma P3.9 strain on bacterial diversity and community composition in loquat rhizosphere，Loquat rhizosphere soil irrigated with T. P3.9 spore suspension were tested by high throughput sequencing on Illumina platform.The results showed that the dominant bacterial community in loquat rhizosphere soil were Proteobacteria,Actinobacteria,Propionibacteriales,Nocardioidaceae,Aeromicrobium. Bacterial diversity in loquat rhizosphere soil added T. P3.9 slightly decrease,but the species and quantity of dominant bacteria did not change.There are dramatically increase one phylum of Nitrospirae,two classes of Nitrospira and Phycisphaerae,three orders of Desulfurellales,Nitrospirales and Tepidisphaerales,three families of Desulfurellaceae,Tepidisphaeraceae and Rhodothermaceae,four genera of Nitrospira, Nitrosospira,Nitrosomonas and Chryseobacterium,four species of Micromonospora auratinigra,Pseudonocardia khuvsgulenisi,Bacteroides vulgatus and Arabidopsis thaliana.There are dramatically decrease one class of Thermoleophilia,five orders of Corynebacteriales,Frankiales,Solirubrobacterales,Kineosporiales and Ktedonobacterales,six families of Nocardiaceae, Geodermatophilaceae,Mycobacteriaceae,Hyphomicrobiaceae,Solirubrobacteraceae and Cryptosporangiaceae ,eleven genera of Amycolatopsis,Smaragdicoccus,Solirubrobacter,Blastococcus,Azohydromonas,Rhodococcus,Bauldia,Nocardia,Micromonospora, Parviterribacter and Fodinicola,three species of Rhodococcus wratislaviensis,Nocardia neocaledoniensis and Fordinicola feengrottensis.Trichoderma P3.9 strain promoted the growth of beneficial bacteria and inhibited growth of pathogenic bacteria in loquat rhizosphere. It could remediate the rhizosphere soil of continuous cropping loquat. |
