- Intervention effect Shading significantly increased rhizosphere soil organic carbon and hydrolyzable nitrogen in cigar tobacco.
- Intervention effect Shading significantly increased rhizosphere soil ammonium nitrogen and nitrate nitrogen in cigar tobacco.
- Intervention effect Shading significantly increased nitrogen contents in tobacco plants.
- Intervention effect Shading significantly affected the arginine biosynthesis pathway in the rhizosphere soil.
- Intervention effect Under shading, the levels of L-oxornithine, citrulline and L-arginine in rhizosphere soil significantly increased.
- Intervention effect Shading significantly altered the rhizosphere microbial community structure and the nitrogen cycling process.
- Intervention effect Under shading, the abundance of organic nitrogen-decomposition genes (gdhA, ansB) significantly increased.
- Mechanism Flavobacterium and Stenotrophomonas may play important roles in the nitrogen cycle in the rhizosphere.
- Association Flavobacterium and Stenotrophomonas were significantly positively correlated with L-glutamic acid, L-ornithine and L-arginine (p < 0.05).
- Mechanism Shading affects nitrogen absorption in crops via changes in the rhizosphere microbial community and the nitrogen cycling process.
