Effects of intercropping different quinoa cultivars on peanut rhizosphere microorganisms and yield in saline-alkali soil.

ABSTRACT: Intercropping is an effective ecological utilization strategy in saline-alkali land, however, the response of peanut rhizosphere microorganisms in saline-alkali soil to different quinoa cultivars used in intercropping is unclear. In this study, a field experiment was conducted to intercrop peanut (IXP, ILP and IQP) with three quinoa cultivars Xinli 3 (IXQ), Longli 4 (ILQ) and Qinling 2 (IQQ), which differed significantly in plant traits. Illumina-based 16S rRNA gene sequencing was used to investigate the microbial diversity of peanut rhizosphere and to explore the relationship between with environment. The peanuts primarily accumulated sodium (Na) in their roots, especially during the vegetative stage (17.5 g/kg), whereas all plant parts substantially accumulated Na in the reproductive sta
