棉花—花生轮作对产量及其土壤微生物群落基因功能的影响
Effects of Cotton-Peanut Rotation on Yield and Genetic Functions of Soil Microbial Communities
摘要
Abstract
In this study,peanut continuous cropping(HC)and cotton continuous cropping(MC)were used as controls,and cotton-peanut rotation(MR)and peanut-cotton rotation(HR)were used as ex-perimental treatments.The harvest yields of different cropping patterns were measured,and their in-ter-root soils were subjected to macro-genome sequencing to comprehensively analyze changes in the microbial communities and functions in the rhizosphere soils of cotton and peanut after long-term cot-ton-peanut rotations.Peanut-cotton rotation increased the yields of cotton and peanut by more than 1 100 kg/hm2.The soil rhizosphere microbial communities of Acidobacteria,Aspergillus,Bradyrhi-zobium,and Green Bentobacteria exhibited the highest richness and effectively improved the soil envi-ronment;there were significant differences in the functions of soil rhizosphere microbial communities under different cropping modes,and the functions of the membrane transporting microbes under the peanut-cotton rotation mode were relatively.Under the peanut-cotton rotation,the membrane trans-porting microbial function was relatively strong;the genes of glycoside hydrolases and glycosyltrans-ferases were the most abundant in the rhizosphere microorganisms in the cotton-peanut rotation;there were significant differences in the protein functions of rhizosphere microorganisms under different cropping modes,and the genes of mycobacterial proteins were mainly based on metabolism function groups,carbohydrate metabolism and amino acid transport;denitrification was significantly increased in the cotton-peanut rotation.Cotton-peanut rotation pattern increased the diversity and abundance of rhizosphere soil microorganisms,enhanced the activities of carbohydrate-active enzymes,metabolic ac-tivities of major metabolic pathways,and increased the abundance of N-related functional genes in the inter-root soil microbial community.The results of the study provide theoretical support for under-standing and utilizing microbial communities and gene functions in the rhizosphere under cotton and peanut rotation system,thereby improving the productivity and quality of cotton and peanut.关键词
